Ghost Nets: Why They Keep Happening and What's Actually Working

Ghost Nets: Why They Keep Happening and What's Actually Working

A viral TikTok about fish aggregation devices drifting into marine protected areas got Andrew thinking about a topic he hasn't covered in a while: ghost nets. In this episode, he breaks down what ghost nets actually are, the scientific term for them (ALDFG, or abandoned, lost, or otherwise discarded fishing gear), and why they're a growing, well-documented problem from the ocean surface all the way down to the deep seafloor.

Andrew walks through what the peer-reviewed research shows: entanglement patterns across whales, seals, sea turtles, and coral reefs, a personal diving story off Big Cayman where he watched a ghost net get cut free from a loggerhead sea turtle, and the real economic and technical challenges holding back solutions like ropeless fishing gear and biodegradable nets. He also covers where progress is actually happening, from derelict net removal programs to circular economy recycling models.

This isn't a "just stop fishing" episode. Andrew makes the case that ghost nets are a solvable, adaptable problem, but one that needs more research funding, cheaper technology, and stronger enforcement to get there.

Takeaways from this episode:

  • Ghost nets (ALDFG) are found from the ocean surface to the deep seafloor, and they keep catching and killing marine life for as long as they remain in the water.
  • The animals most affected span whales, seals, sea turtles, and coral reef species, not just fish.
  • Solutions like ropeless gear and biodegradable nets are real and improving, but cost and fisher adoption remain the biggest barriers.
  • Stopping fishing altogether isn't a realistic fix. The path forward is better gear design, more funding, and stronger enforcement.
  • Listeners can support the fisheries and programs that are already investing in gear-loss prevention and removal.

00:00:00,000 --> 00:00:01,333
Something kind of crazy happened to me

2
00:00:01,333 --> 00:00:02,625
the other day on TikTok.

3
00:00:03,333 --> 00:00:05,000
I had a video that went viral, a post

4
00:00:05,000 --> 00:00:07,375
that I talked about FADs,

5
00:00:07,375 --> 00:00:08,083
the fish aggregation

6
00:00:08,083 --> 00:00:10,166
devices that were for tuna.

7
00:00:10,916 --> 00:00:12,916
And some of these fish aggregation

8
00:00:12,916 --> 00:00:14,166
devices, these FADs,

9
00:00:14,166 --> 00:00:15,500
were going into,

10
00:00:15,500 --> 00:00:16,875
floating into marine protectors.

11
00:00:17,416 --> 00:00:19,000
Essentially, they were lost. They were

12
00:00:19,000 --> 00:00:20,041
almost like a ghost net.

13
00:00:20,708 --> 00:00:22,791
And the post went viral.

14
00:00:23,250 --> 00:00:24,666
At this point of recording,

15
00:00:24,666 --> 00:00:26,500
I have over 100,000 views.

16
00:00:26,666 --> 00:00:27,625
And normally, I get like

17
00:00:27,625 --> 00:00:29,500
200 views, maybe 300 views.

18
00:00:29,541 --> 00:00:31,958
And it went viral. It went crazy. I got a

19
00:00:31,958 --> 00:00:33,208
lot of eyes on the profile.

20
00:00:33,208 --> 00:00:34,916
I got eyes on the podcast, which was

21
00:00:34,916 --> 00:00:35,875
great. And it was fun.

22
00:00:35,875 --> 00:00:36,958
I got some interesting comments, of

23
00:00:36,958 --> 00:00:38,708
course, but it was a lot of fun to be

24
00:00:38,708 --> 00:00:39,750
able to see that happen.

25
00:00:39,750 --> 00:00:41,500
And it made me think, you know what? I

26
00:00:41,500 --> 00:00:42,791
haven't done a ghost

27
00:00:42,791 --> 00:00:44,375
net podcast in a while.

28
00:00:45,083 --> 00:00:47,458
And with all of this AI and search engine

29
00:00:47,458 --> 00:00:49,208
optimization, just to be transparent,

30
00:00:49,666 --> 00:00:51,291
it's starting to look at, you know,

31
00:00:51,291 --> 00:00:54,416
podcasts and pages on websites that are

32
00:00:54,416 --> 00:00:55,916
showing that they know

33
00:00:55,958 --> 00:00:57,666
a little bit about certain parts of the

34
00:00:57,666 --> 00:00:58,500
subject. So what I wanted to

35
00:00:58,500 --> 00:00:59,833
do is cover a little bit about

36
00:01:00,041 --> 00:01:02,291
ghost nets, what they are, how do we, why

37
00:01:02,291 --> 00:01:03,416
they keep happening? Why

38
00:01:03,416 --> 00:01:04,333
do we keep seeing them?

39
00:01:04,708 --> 00:01:06,416
What's being done to clean them up and so

40
00:01:06,416 --> 00:01:07,083
forth. And we're going to

41
00:01:07,083 --> 00:01:08,416
talk about that on today's

42
00:01:08,416 --> 00:01:10,041
episode of the how to protect the ocean

43
00:01:10,041 --> 00:01:10,833
podcast, because this is

44
00:01:10,833 --> 00:01:12,708
where you find your weekday ocean

45
00:01:12,708 --> 00:01:16,625
news Monday to Friday on oceans. And this

46
00:01:16,625 --> 00:01:17,625
is your ocean resource. So

47
00:01:17,625 --> 00:01:18,916
this is what I want to do for

48
00:01:18,916 --> 00:01:21,125
you is be your ocean resource. So if you

49
00:01:21,125 --> 00:01:22,333
want me to get that, or

50
00:01:22,333 --> 00:01:23,375
you want me to provide that,

51
00:01:23,750 --> 00:01:25,916
you can go to your favorite podcast app

52
00:01:25,916 --> 00:01:26,625
that you're listening this on

53
00:01:26,625 --> 00:01:27,375
and say, Hey, you know what,

54
00:01:27,375 --> 00:01:28,791
I'm going to follow this, just click that

55
00:01:28,791 --> 00:01:30,208
button, don't tap it, click

56
00:01:30,208 --> 00:01:32,500
it, whatever you do. And I

57
00:01:32,500 --> 00:01:36,125
will be in your feed Monday to Friday. So

58
00:01:36,125 --> 00:01:36,833
you can take a look at that,

59
00:01:36,833 --> 00:01:37,750
or you can take a listen to

60
00:01:37,750 --> 00:01:39,791
that. So that's always fun. So follow

61
00:01:39,791 --> 00:01:40,833
that. And of course, if you want to

62
00:01:40,833 --> 00:01:41,708

if you feel the need to support all the

64
00:01:43,500 --> 00:01:44,166
stuff we do, we do the

65
00:01:44,166 --> 00:01:45,541
podcast, we do YouTube, I'm going

66
00:01:45,541 --> 00:01:47,125
to be starting doing ocean decoded live

67
00:01:47,125 --> 00:01:49,458
Monday to Fridays. I'm also

68
00:01:49,458 --> 00:01:51,500
going to be I do things on

69
00:01:51,541 --> 00:01:53,750
Tik TOK and Instagram and Facebook and so

70
00:01:53,750 --> 00:01:55,208
forth. And so if you enjoy

71
00:01:55,208 --> 00:01:56,416
that and you want to support

72
00:01:56,416 --> 00:01:58,333
me, you can go to speak up for blue.com

73

speak up for blue.com forward

75
00:02:02,958 --> 00:02:05,958
slash Patreon. Now I want to talk about

76
00:02:05,958 --> 00:02:07,916
ghost nets because ghost

77
00:02:07,916 --> 00:02:08,708
nets are really interesting.

78
00:02:08,708 --> 00:02:09,916
If you don't know what ghost nets are,

79
00:02:09,916 --> 00:02:12,791
essentially they are nets that have been

80
00:02:12,791 --> 00:02:14,500
lost at sea. So these

81
00:02:14,500 --> 00:02:17,000
are fishing nets that have been used and

82
00:02:17,000 --> 00:02:18,500
maybe lost because of bad

83
00:02:18,500 --> 00:02:19,583
weather, or maybe they're

84
00:02:19,583 --> 00:02:21,666
discarded over the boat, but they've

85
00:02:21,666 --> 00:02:23,125
essentially been lost. And what they do

86
00:02:23,125 --> 00:02:24,291
is these, these large

87
00:02:24,333 --> 00:02:27,416
nets are found all over the world in the

88
00:02:27,416 --> 00:02:28,541
oceans, whether it's in the

89
00:02:28,541 --> 00:02:29,750
deep sea, whether it's in the

90
00:02:29,750 --> 00:02:31,333
floating on the top or whether it's in

91
00:02:31,333 --> 00:02:32,541
the water column, and they

92
00:02:32,541 --> 00:02:34,916
continue to catch fish, marine

93
00:02:34,916 --> 00:02:37,875
mammals, sea turtles, other fish like

94
00:02:37,875 --> 00:02:41,041
sharks and so forth. And they die, they

95
00:02:41,041 --> 00:02:41,875
can't, they can't get

96
00:02:41,875 --> 00:02:43,250
out of it and they end up dying, but

97
00:02:43,250 --> 00:02:45,208
nobody's fishing them because

98
00:02:45,208 --> 00:02:46,208
it's just, it's a net that's

99
00:02:46,250 --> 00:02:48,583
just floating. It's a ghost net. And the

100
00:02:48,583 --> 00:02:50,416
scientific term actually is abandoned,

101
00:02:50,791 --> 00:02:52,583
lost or otherwise discarded

102
00:02:52,583 --> 00:02:55,833
fishing gear known as ALDFG.

103
00:02:55,916 --> 00:02:57,541
It's a huge acronym. It doesn't really

104
00:02:57,541 --> 00:02:59,583
sound like anything really important, but

105
00:02:59,583 --> 00:03:00,916
it's something that's, that's really

106
00:03:00,916 --> 00:03:02,541
important. It's defined as

107
00:03:03,208 --> 00:03:05,458
gear that continues to catch or kill

108
00:03:05,458 --> 00:03:08,250
marine life with no one checking or

109
00:03:08,250 --> 00:03:10,458
retrieving it. And it's a process called

110
00:03:10,458 --> 00:03:11,791
ghost fishing. So

111
00:03:11,791 --> 00:03:13,208
ghost nets, ghost fishing,

112
00:03:13,375 --> 00:03:15,416
go hand in hand. And it's recognized in

113
00:03:15,416 --> 00:03:19,083
the peer review literature as a major and

114
00:03:19,083 --> 00:03:20,708
growing contributor to marine plastic

115
00:03:20,708 --> 00:03:23,083
pollution distinct from other litter

116
00:03:23,083 --> 00:03:24,708
because it is specifically designed to

117
00:03:24,708 --> 00:03:26,458
catch and hold living things.

118
00:03:27,083 --> 00:03:29,666
Now, a 2023 deep sea survey around the

119
00:03:29,666 --> 00:03:33,000
Azores near Portugal or in Portugal used

120
00:03:33,000 --> 00:03:36,750
351 dives and 15 years of seafloor

121
00:03:36,750 --> 00:03:39,458
footage from 2006 to 2020

122
00:03:39,458 --> 00:03:41,666
and found an average of roughly

123
00:03:41,708 --> 00:03:47,666
597 items of ghost nets related gear per

124
00:03:47,666 --> 00:03:50,791
square kilometer on the seafloor. That's

125
00:03:50,791 --> 00:03:53,500
per square kilometer. It shows that it

126
00:03:53,500 --> 00:03:54,541
isn't just the surface

127
00:03:54,541 --> 00:03:55,625
or a coastal problem.

128
00:03:55,916 --> 00:03:58,125
It reaches the deep sea as well. So

129
00:03:58,125 --> 00:03:59,500
that's obviously something that we don't

130
00:03:59,500 --> 00:04:01,625
like to see, but this is something that

131
00:04:01,625 --> 00:04:04,250
we need to dive into. So why does ghost

132
00:04:04,250 --> 00:04:05,666
net really matter other

133
00:04:05,666 --> 00:04:06,666
than just catching fish?

134
00:04:06,958 --> 00:04:09,083
Well, a study using social media records

135
00:04:09,083 --> 00:04:12,041
from 2012 to 2023 documented 144

136
00:04:12,041 --> 00:04:16,458
individual animals across 35 species, 13

137
00:04:16,458 --> 00:04:18,041
of them were actually endangered or

138
00:04:18,041 --> 00:04:20,500
vulnerable were entangled in derelict

139
00:04:20,500 --> 00:04:22,291
gear in the Indian

140
00:04:22,291 --> 00:04:23,458
coastal and freshwater systems.

141
00:04:23,666 --> 00:04:26,583
So that's just one study. Now we know

142
00:04:26,583 --> 00:04:28,916
with the North Atlantic right whale, we

143
00:04:28,916 --> 00:04:30,958
see entanglements all the time. Sometimes

144
00:04:30,958 --> 00:04:32,958
we don't see those entanglements and you

145
00:04:32,958 --> 00:04:34,166
know, the whales will wash up or

146
00:04:34,166 --> 00:04:34,916
sometimes we don't see them

147
00:04:34,916 --> 00:04:35,666
at all, but they're entangled.

148
00:04:35,666 --> 00:04:38,333
And what happens is the nets get caught

149
00:04:38,333 --> 00:04:40,916
or the ropes get the lines get caught on

150
00:04:40,916 --> 00:04:43,208
their pectoral fins. And as they continue

151
00:04:43,208 --> 00:04:45,208
to swim, the lines dig into their

152
00:04:45,208 --> 00:04:47,750
pectoral fins and it continues to make a

153
00:04:47,750 --> 00:04:50,083
mark. It starts to bleed. It gets

154
00:04:50,083 --> 00:04:52,500
infected and eventually the animal can

155
00:04:52,500 --> 00:04:55,541
die. It can also be see seals and sea

156
00:04:55,541 --> 00:04:57,208
lines that like the nets around their

157
00:04:57,208 --> 00:04:58,000
neck. It can cause

158
00:04:58,000 --> 00:04:59,666
asphyxiation, strangle them.

159
00:04:59,708 --> 00:05:02,375
It could also cause a lot of problems

160
00:05:02,375 --> 00:05:04,541
trying to feed or anything like that.

161
00:05:04,916 --> 00:05:07,541
There are people who roam beaches to try

162
00:05:07,541 --> 00:05:10,500
and free sea lions and seals with these

163
00:05:10,500 --> 00:05:12,041
nets around their neck. And unfortunately

164
00:05:12,041 --> 00:05:13,666
it happens to too many people.

165
00:05:13,708 --> 00:05:15,333
And of course sea turtle hatchling

166
00:05:15,333 --> 00:05:17,708
mortality has been directly linked to

167
00:05:17,708 --> 00:05:20,333
derelict nets and synthetic rope

168
00:05:20,333 --> 00:05:23,333
entanglement in recent fishing in recent

169
00:05:23,333 --> 00:05:26,041
field research with over 200 dead

170
00:05:26,041 --> 00:05:26,750
hatchlings recorded

171
00:05:26,750 --> 00:05:29,000
primarily trapped in the gear.

172
00:05:29,416 --> 00:05:31,916
And that was a study in 2025. Now, of

173
00:05:31,916 --> 00:05:33,166
course, I talked a little bit about deep

174
00:05:33,166 --> 00:05:35,291
sea impacts, but researchers have found

175
00:05:35,291 --> 00:05:39,208
that ALDFG entangled in cold water coral

176
00:05:39,208 --> 00:05:41,375
colonies across multiple regions,

177
00:05:41,583 --> 00:05:42,666
including the northwestern Mediterranean.

178
00:05:42,708 --> 00:05:45,916
The Lingeran Sea, England's Atlantic

179
00:05:45,916 --> 00:05:49,208
Coast and the Azores showing is this is a

180
00:05:49,208 --> 00:05:52,375
consistent cross sectional pattern rather

181
00:05:52,375 --> 00:05:53,666
than an isolated finding.

182
00:05:54,291 --> 00:05:56,000
So this is something that's happening

183
00:05:56,000 --> 00:05:57,916
more and more in a related study

184
00:05:57,916 --> 00:06:00,458
specifically examined how abandoned ghost

185
00:06:00,458 --> 00:06:02,416
neck gear becomes incorporated into

186
00:06:02,416 --> 00:06:04,208
structural growth of the coral species.

187
00:06:04,750 --> 00:06:08,333
Dendrophilia, Philia, Dendrophilia ramia

188
00:06:08,333 --> 00:06:10,875
along Portugal's Atlantic Coast,

189
00:06:11,166 --> 00:06:11,666
illustrating how litter flies and the other.

190
00:06:11,666 --> 00:06:14,333
And how litter physically integrates into

191
00:06:14,333 --> 00:06:16,625
living restructures over time. Now, one

192
00:06:16,625 --> 00:06:18,583
of the interesting stories of like diving

193
00:06:18,583 --> 00:06:20,666
stories that I have is I remember diving

194
00:06:20,666 --> 00:06:22,583
off the coast of the

195
00:06:22,583 --> 00:06:24,208
Cayman Islands, Big Cayman.

196
00:06:24,625 --> 00:06:26,708
And I was diving with some older people

197
00:06:26,708 --> 00:06:28,833
like in their 50s and 60s. They have a

198
00:06:28,833 --> 00:06:29,958
lot more experience than I do. They were

199
00:06:29,958 --> 00:06:30,666
in rebreathers and stuff.

200
00:06:30,666 --> 00:06:33,125
And we were doing a dive start off at 100

201
00:06:33,125 --> 00:06:34,833
feet. That was our deepest depth. Then we

202
00:06:34,833 --> 00:06:36,750
started to kind of slowly climb up on a

203
00:06:36,750 --> 00:06:39,583
reef about 60 days, 70 feet body amount

204
00:06:39,583 --> 00:06:41,750
and kind of hanging out there.

205
00:06:41,750 --> 00:06:43,833
And one of the guys was a diver and

206
00:06:43,833 --> 00:06:46,125
obviously and he was doing something

207
00:06:46,125 --> 00:06:48,000
around a coral reef and I was like, Oh,

208
00:06:48,000 --> 00:06:48,666
what's he doing? So I kind of came around to watch.

209
00:06:48,666 --> 00:06:51,416
He had a knife out and he was actually

210
00:06:51,416 --> 00:06:54,458
taking off some fishing net gear that had

211
00:06:54,458 --> 00:06:56,291
been lost. So, you know, these ghost nets

212
00:06:56,291 --> 00:06:58,250
and there were some species in there like

213
00:06:58,250 --> 00:07:00,125
some little shrimp and some nematodes and

214
00:07:00,125 --> 00:07:01,416
some fish and stuff like that.

215
00:07:01,416 --> 00:07:03,666
So he was actually cutting them off. And

216
00:07:03,666 --> 00:07:05,000
what was interesting about it is like

217
00:07:05,000 --> 00:07:06,750
during that time, I'm saying you got a

218
00:07:06,750 --> 00:07:08,041
picture as both scuba diving.

219
00:07:08,041 --> 00:07:09,875
He's kind of floating above the reef. I'm

220
00:07:09,875 --> 00:07:11,125
floating above the reef, probably about

221
00:07:11,125 --> 00:07:12,916
two feet above him. And we're just kind

222
00:07:12,916 --> 00:07:13,666
of maybe a little bit more in line than that.

223
00:07:13,666 --> 00:07:16,041
Maybe it wasn't two feet and where

224
00:07:16,041 --> 00:07:17,541
there's a bit of a space in between us.

225
00:07:17,541 --> 00:07:19,708
And as we're watch as I'm watching this

226
00:07:19,708 --> 00:07:22,458
guy take the ghost net gear off this

227
00:07:22,458 --> 00:07:23,458
loggerhead sea turtle

228
00:07:23,458 --> 00:07:25,000
comes right over top of us.

229
00:07:25,375 --> 00:07:27,125
And he just kind of peaks his head. He or

230
00:07:27,125 --> 00:07:29,833
she, I don't remember peaks head and he

231
00:07:29,833 --> 00:07:31,375
starts looking at us and he looks at both

232
00:07:31,375 --> 00:07:32,125
of us and kind of

233
00:07:32,125 --> 00:07:34,083
feels like he gave a nod.

234
00:07:34,083 --> 00:07:35,875
I'm probably exaggerating a little bit,

235
00:07:35,875 --> 00:07:37,416
but it feels like he gave a nod and just

236
00:07:37,416 --> 00:07:38,750
kind of came out almost like a, Hey,

237
00:07:38,750 --> 00:07:39,375
thanks a lot for

238
00:07:39,375 --> 00:07:40,458
taking this away from us.

239
00:07:40,916 --> 00:07:42,541
But this is your stuff anyway. So take it

240
00:07:42,541 --> 00:07:44,250
back to the surface and keep it there,

241
00:07:44,250 --> 00:07:45,875
which is where we want to do. We don't,

242
00:07:45,875 --> 00:07:48,416
we want to keep it back at the surface

243
00:07:48,416 --> 00:07:50,083
because we don't want that to keep coming

244
00:07:50,083 --> 00:07:53,083
out onto the bottom, right?

245
00:07:53,083 --> 00:07:54,458
Because that's something that, you know,

246
00:07:54,458 --> 00:07:57,416
we just don't want to do. Now, one of the

247
00:07:57,416 --> 00:07:59,375
things that's interesting beyond like

248
00:07:59,375 --> 00:08:01,625
looking at seeing ghost nets in the

249
00:08:01,625 --> 00:08:02,625
waters, why it keeps happening.

250
00:08:02,708 --> 00:08:05,791
So some of the challenges that have been

251
00:08:05,791 --> 00:08:07,458
identified in some of the research that I

252
00:08:07,458 --> 00:08:10,291
looked up in the literature. So there's

253
00:08:10,291 --> 00:08:12,250
also there's an economic cost to the

254
00:08:12,250 --> 00:08:13,666
fishing industry itself, right? Because

255
00:08:13,666 --> 00:08:15,833
you lose the nets. It's

256
00:08:15,833 --> 00:08:17,666
something that's a big problem.

257
00:08:18,083 --> 00:08:20,666
A 2023 study modeling the English channel

258
00:08:20,666 --> 00:08:23,208
static gear fishery found real economic

259
00:08:23,208 --> 00:08:25,500
costs tied to gear loss and ghost fishing

260
00:08:25,500 --> 00:08:27,791
and found that current biodegradable gear

261
00:08:27,791 --> 00:08:29,916
designs need improvement before

262
00:08:29,916 --> 00:08:32,250
meaningfully reducing the

263
00:08:32,250 --> 00:08:34,500
costs of these types of gear.

264
00:08:34,500 --> 00:08:36,208
So there needs to be more research in the

265
00:08:36,208 --> 00:08:38,291
biodegradable gear in case it does get

266
00:08:38,291 --> 00:08:39,750
lost. It could just biodegrade. It could

267
00:08:39,750 --> 00:08:41,541
just basically disintegrate into the

268
00:08:41,541 --> 00:08:43,625
ocean without having problems. Obviously,

269
00:08:43,625 --> 00:08:44,708
we're not there yet and

270
00:08:44,708 --> 00:08:45,666
there still needs to be done.

271
00:08:45,708 --> 00:08:48,625
But look, about 10 years ago when I was

272
00:08:48,625 --> 00:08:50,500
at the International Marine Conservation

273
00:08:50,500 --> 00:08:53,375
Congress, there was a hackathon that was

274
00:08:53,375 --> 00:08:56,083
happening in Malaysia. And I remember it

275
00:08:56,083 --> 00:08:57,833
was a really cool thing. They had all

276
00:08:57,833 --> 00:08:59,041
these engineers, all these people who

277
00:08:59,041 --> 00:09:00,916
like to do these hackathons. And then we

278
00:09:00,916 --> 00:09:02,708
had a presentation. There were five ocean

279
00:09:02,708 --> 00:09:04,291
issues that we were dealing with. One of

280
00:09:04,291 --> 00:09:07,125
them was crab and lobster fishing and all

281
00:09:07,125 --> 00:09:08,708
that kind of coming up with a fishing

282
00:09:08,708 --> 00:09:10,666
gear that would reduce entanglement.

283
00:09:10,708 --> 00:09:13,500
And one of the ideas was to have a

284
00:09:13,500 --> 00:09:17,750
ropeless or a lineless lobster or crab

285
00:09:17,750 --> 00:09:21,125
trap. And so what was basically the idea

286
00:09:21,125 --> 00:09:22,708
that was done in the prototype that was

287
00:09:22,708 --> 00:09:24,166
done that actually won the competition,

288
00:09:24,666 --> 00:09:25,666
even though there's other

289
00:09:25,666 --> 00:09:26,541
issues that they covered.

290
00:09:27,250 --> 00:09:29,375
They actually had this ropeless one where

291
00:09:29,375 --> 00:09:31,166
you'd have balloons that would pop up.

292
00:09:31,625 --> 00:09:33,416
And when you press the button as you want

293
00:09:33,416 --> 00:09:35,083
to retrieve your gear and it

294
00:09:35,083 --> 00:09:36,333
would float to the surface.

295
00:09:37,500 --> 00:09:39,166
Now, when that first came out, people

296
00:09:39,166 --> 00:09:40,416
were like, "This isn't going to work.

297
00:09:40,416 --> 00:09:41,333
There's going to be a lot of problems.

298
00:09:41,333 --> 00:09:42,666
The ocean is pretty harsh. How are we

299
00:09:42,666 --> 00:09:43,916
going to find it?" All this kind of

300
00:09:43,916 --> 00:09:45,708
stuff. And we still need to put buoys to

301
00:09:45,708 --> 00:09:47,583
make sure we can find it and GPS tracks

302
00:09:47,583 --> 00:09:48,375
and everything like that.

303
00:09:48,500 --> 00:09:49,708
And there were a lot of problems when

304
00:09:49,708 --> 00:09:51,166
they tried it out. I remember talking to

305
00:09:51,166 --> 00:09:52,750
some fishers and they were saying, "Yeah,

306
00:09:52,750 --> 00:09:55,000
it's really expensive. We don't really

307
00:09:55,000 --> 00:09:57,166
know if it's going to be working." And

308
00:09:57,166 --> 00:09:58,250
some of the trials haven't

309
00:09:58,250 --> 00:09:59,666
really shown that it worked.

310
00:09:59,708 --> 00:10:01,916
But it gets better and better. The

311
00:10:01,916 --> 00:10:03,458
technology gets better and better as more

312
00:10:03,458 --> 00:10:05,416
experimentation happens and as people are

313
00:10:05,416 --> 00:10:07,833
trying it out. And now there's a lot of

314
00:10:07,833 --> 00:10:10,166
fisheries in Canada on the east coast

315
00:10:10,166 --> 00:10:12,833
that are experimenting with this and see

316
00:10:12,833 --> 00:10:15,000
how much retrieval can

317
00:10:15,000 --> 00:10:16,333
happen and all that kind of stuff.

318
00:10:16,333 --> 00:10:17,958
And the gear is getting cheaper and

319
00:10:17,958 --> 00:10:19,166
cheaper. So we're starting to see some

320
00:10:19,166 --> 00:10:21,750
headway. So, you know, with biodegradable

321
00:10:21,750 --> 00:10:24,916
nets, we might see some more headway as

322
00:10:24,916 --> 00:10:25,666
we move into the future.

323
00:10:25,708 --> 00:10:28,625
So I think it's good, but it isn't a

324
00:10:28,625 --> 00:10:31,666
simple fix yet. A 2025 laboratory

325
00:10:31,666 --> 00:10:34,375
comparison of biodegradable copolyester

326
00:10:34,375 --> 00:10:36,750
microfilaments against traditional

327
00:10:36,750 --> 00:10:40,833
polyamide monofilaments tested degrading

328
00:10:40,833 --> 00:10:42,250
degradation rates

329
00:10:42,250 --> 00:10:43,666
under accelerated aging.

330
00:10:43,666 --> 00:10:46,541
But part of an active research effort to

331
00:10:46,541 --> 00:10:48,291
find materials that break down fast

332
00:10:48,291 --> 00:10:50,041
enough to stop ghost fishing, but it

333
00:10:50,041 --> 00:10:52,708
didn't, but hold up long

334
00:10:52,708 --> 00:10:54,833
enough to still catch the fish.

335
00:10:55,500 --> 00:10:56,583
But there still needs to be

336
00:10:56,583 --> 00:10:58,166
experimentation on that one. And in

337
00:10:58,166 --> 00:11:00,291
economic feasibility research cited in

338
00:11:00,291 --> 00:11:02,916
2025, synthesis found biodegradable gear

339
00:11:02,916 --> 00:11:06,000
runs about 30 to 50% more expensive than

340
00:11:06,000 --> 00:11:07,666
conventional gear on average.

341
00:11:07,708 --> 00:11:11,000
And a major barrier for small scale

342
00:11:11,000 --> 00:11:13,458
fishing operations on tight margins,

343
00:11:13,791 --> 00:11:14,458
particularly in low

344
00:11:14,458 --> 00:11:16,166
income fishing communities.

345
00:11:16,625 --> 00:11:20,083
In 2025, experimental study of Norwegian

346
00:11:20,083 --> 00:11:22,458
fishers found willingness to adopt

347
00:11:22,458 --> 00:11:25,250
biodegradable gear is highly conditional.

348
00:11:25,833 --> 00:11:28,083
Right. The fishers will switch if catch

349
00:11:28,083 --> 00:11:30,000
efficiencies matches conventional gear.

350
00:11:30,375 --> 00:11:33,500
That makes sense. But as relative

351
00:11:33,500 --> 00:11:35,583
efficiency drops, adoption becomes

352
00:11:35,583 --> 00:11:38,083
contingent on whether the other fishers

353
00:11:38,083 --> 00:11:40,208
adopted too. So it's a little bit of a

354
00:11:40,208 --> 00:11:41,416
peer pressure thing.

355
00:11:41,833 --> 00:11:44,125
Meaning individual incentives are likely

356
00:11:44,125 --> 00:11:47,750
won't alone won't likely drive the shift.

357
00:11:48,208 --> 00:11:49,500
So that's something that's interesting.

358
00:11:49,500 --> 00:11:50,500
And of course, local knowledge and

359
00:11:50,500 --> 00:11:52,500
enforcement gaps are really important. A

360
00:11:52,500 --> 00:11:55,291
2026 study in Cameron small scale fishing

361
00:11:55,291 --> 00:11:58,833
marine fisheries used local ecological

362
00:11:58,833 --> 00:12:00,250
knowledge from fishers and state

363
00:12:00,250 --> 00:12:02,000
professionals and state officials to

364
00:12:02,000 --> 00:12:04,791
examine why gear gets lost, abandoned or

365
00:12:04,791 --> 00:12:07,333
discarded and found that weak enforcement

366
00:12:07,333 --> 00:12:09,666
of gear registration and marking policies

367
00:12:09,875 --> 00:12:12,000
means fishers face little to no

368
00:12:12,000 --> 00:12:13,125
consequences for

369
00:12:13,125 --> 00:12:15,041
failing to report lost gear.

370
00:12:15,916 --> 00:12:16,916
So there's a lot of, you know, still a

371
00:12:16,916 --> 00:12:17,750
lot of problems with some of the

372
00:12:17,750 --> 00:12:19,083
solutions that are out there, but

373
00:12:19,083 --> 00:12:20,875
something that's working solutions that

374
00:12:20,875 --> 00:12:22,833
are being tested within that

375
00:12:22,833 --> 00:12:23,666
I looked up in the literature.

376
00:12:23,666 --> 00:12:26,250
So there's systematic evidence for

377
00:12:26,250 --> 00:12:28,333
recycling. So 2026 systematic literature

378
00:12:28,333 --> 00:12:30,750
review following Prisma methodology,

379
00:12:31,041 --> 00:12:33,166
synthesized at 17 peer reviewed studies

380
00:12:33,166 --> 00:12:37,541
from 2015 to 2025 across marine ecology

381
00:12:37,541 --> 00:12:39,625
materials and engineering and circular

382
00:12:39,625 --> 00:12:41,666
economy research evaluating both

383
00:12:41,666 --> 00:12:44,416
ecological impacts of ghost nets and the

384
00:12:44,416 --> 00:12:46,750
technical feasibility of recycling

385
00:12:46,750 --> 00:12:49,416
recovered fishing gear polymers into new

386
00:12:49,416 --> 00:12:52,666
products using Hawaii as a case model.

387
00:12:52,708 --> 00:12:54,958
So there have been some successes around

388
00:12:54,958 --> 00:12:56,583
there. And of course, researchers from

389
00:12:56,583 --> 00:12:58,083
British Columbia, Salish Sea documents

390
00:12:58,083 --> 00:13:00,625
active derelict net removal programs

391
00:13:00,625 --> 00:13:03,208
designed specifically around safeguarding

392
00:13:03,208 --> 00:13:05,416
habitat and reducing mortality across

393
00:13:05,416 --> 00:13:08,125
multiple species cited a model approach

394
00:13:08,125 --> 00:13:10,625
within deep sea ghost net literature.

395
00:13:10,708 --> 00:13:12,083
So that's nice to see that there are some

396
00:13:12,083 --> 00:13:13,875
things that are working out. And of

397
00:13:13,875 --> 00:13:15,041
course, there's still material science

398
00:13:15,041 --> 00:13:17,000
progress is happening ongoing degradation

399
00:13:17,000 --> 00:13:21,291
testing of specific polymers represents

400
00:13:21,291 --> 00:13:23,583
the live edge of material research aimed

401
00:13:23,583 --> 00:13:25,208
at gear that ghost net

402
00:13:25,208 --> 00:13:27,750
fish fishes for months.

403
00:13:28,000 --> 00:13:29,541
So that's not century. So that's good.

404
00:13:29,541 --> 00:13:31,041
We're starting to see a reduction in that

405
00:13:31,041 --> 00:13:33,458
by like 100 years, which is great to see.

406
00:13:33,916 --> 00:13:36,166
So look, the peer reviewed literature

407
00:13:36,166 --> 00:13:38,416
that we looked up for this study is for

408
00:13:38,416 --> 00:13:39,666
this episode is consistent.

409
00:13:39,833 --> 00:13:44,250
Ghost nets is a measurable quantifiable

410
00:13:44,250 --> 00:13:46,333
problem from the sea surface to the deep

411
00:13:46,333 --> 00:13:48,416
sea. We definitely know that it's

412
00:13:48,416 --> 00:13:50,166
definitely a problem. And the fixes on

413
00:13:50,166 --> 00:13:52,208
the table like biodegradable materials or

414
00:13:52,208 --> 00:13:54,583
recycling better enforcement are all

415
00:13:54,583 --> 00:13:57,208
real, but each comes with its own trade

416
00:13:57,208 --> 00:13:58,375
off that scientists are

417
00:13:58,375 --> 00:13:59,666
actively working through.

418
00:13:59,666 --> 00:14:02,458
And we need more progress. We need more

419
00:14:02,458 --> 00:14:04,666
research on this. We need more pilot

420
00:14:04,666 --> 00:14:06,625
studies on this to ensure that these

421
00:14:06,625 --> 00:14:09,541
ghost nets, one can not affect other

422
00:14:09,541 --> 00:14:11,791
fishes or marine mammals or sea turtles

423
00:14:11,791 --> 00:14:13,000
or sea birds. I always

424
00:14:13,000 --> 00:14:14,458
forget seabirds in that last one.

425
00:14:15,041 --> 00:14:17,583
But also like to be able to have more

426
00:14:17,583 --> 00:14:20,791
efficiency and less expand, make sure

427
00:14:20,791 --> 00:14:22,208
they're less expensive so that they'll be

428
00:14:22,208 --> 00:14:24,625
adopted by fishers. A lot of times

429
00:14:24,625 --> 00:14:25,958
fishers who use these

430
00:14:25,958 --> 00:14:26,666
types of nets are small scale.

431
00:14:26,666 --> 00:14:30,500
They don't have a big budget. Some of the

432
00:14:30,500 --> 00:14:32,708
major corporations do have those big

433
00:14:32,708 --> 00:14:34,416
budgets so they could be using this type

434
00:14:34,416 --> 00:14:36,666
of stuff too. But a lot of the fishers

435
00:14:36,666 --> 00:14:38,000
don't have it and we need to make sure we

436
00:14:38,000 --> 00:14:39,125
can get those in those hands.

437
00:14:39,541 --> 00:14:43,000
So lots of research, more funding and

438
00:14:43,000 --> 00:14:45,208
more adoption is needed. And there's a

439
00:14:45,208 --> 00:14:46,625
lot of stuff that we talked about today.

440
00:14:46,625 --> 00:14:47,625
And I would love to hear from you what

441
00:14:47,625 --> 00:14:50,000
you think is needed when we look at

442
00:14:50,000 --> 00:14:51,666
managing ghost nets and making sure.

443
00:14:51,708 --> 00:14:54,041
And I know a lot of people will say, Hey,

444
00:14:54,041 --> 00:14:55,083
you know what? We just got to stop

445
00:14:55,083 --> 00:14:56,625
fishing and reduce fishing in certain

446
00:14:56,625 --> 00:14:57,916
situations that's going to work in other

447
00:14:57,916 --> 00:14:59,208
situations. It's not going to work

448
00:14:59,208 --> 00:15:01,083
because people need to fish. They need to

449
00:15:01,083 --> 00:15:02,375
their protein source. They need to make

450
00:15:02,375 --> 00:15:04,083
money for their families. It's not going

451
00:15:04,083 --> 00:15:05,750
away anytime soon. There are certain

452
00:15:05,750 --> 00:15:07,708
cases that yet can be reduced to nothing.

453
00:15:08,000 --> 00:15:09,375
But there's other situations where

454
00:15:09,375 --> 00:15:11,166
fishing is just always going to happen.

455
00:15:11,166 --> 00:15:12,958
And we need to make sure that we can

456
00:15:12,958 --> 00:15:15,666
adapt to that as quickly as possible.

457
00:15:15,708 --> 00:15:17,625
