Who Decides How Much Fish Ends Up on Your Plate?

Most people assume fisheries are either working or failing, but very few people know how the system actually works. In this episode, I break down the hidden process behind fishing limits, stock assessments, political negotiations, and the science that shapes what ends up on your plate.
You will learn why fisheries management can go wrong, what happens when countries ignore the science, and how better systems like harvest rules and stronger accountability can help fisheries recover. This episode also sets up tomorrow’s interview with Susan Jackson from ISSF, where we will reveal just how far tuna fisheries have come.

00:00:00,291 --> 00:00:01,041
Most people think
2
00:00:01,041 --> 00:00:02,666
fisheries management is broken.
3
00:00:03,125 --> 00:00:04,333
Too political, too slow,
4
00:00:04,791 --> 00:00:06,000
too disconnected from science.
5
00:00:06,583 --> 00:00:07,625
And honestly, a lot of the
6
00:00:07,625 --> 00:00:09,208
time, they're right, it's true.
7
00:00:09,916 --> 00:00:10,500
But what if I told you
8
00:00:10,500 --> 00:00:11,625
there's one global fishery
9
00:00:11,625 --> 00:00:12,291
where things have
10
00:00:12,291 --> 00:00:14,916
actually started to turn around?
11
00:00:14,916 --> 00:00:16,875
Not perfectly, but measurably.
12
00:00:17,458 --> 00:00:18,500
And tomorrow I'm bringing on a guest
13
00:00:18,500 --> 00:00:20,291
who's gonna walk through just how big
14
00:00:20,583 --> 00:00:21,916
of the shift really is.
15
00:00:22,166 --> 00:00:23,791
But today, we need to
16
00:00:23,791 --> 00:00:25,000
understand the system first.
17
00:00:25,416 --> 00:00:26,250
Because if you see
18
00:00:26,250 --> 00:00:27,375
how fisheries management
19
00:00:27,500 --> 00:00:29,416
actually operates, you'll understand
20
00:00:29,583 --> 00:00:31,875
why the result matters so much.
21
00:00:32,500 --> 00:00:33,000
This is the How to
22
00:00:33,000 --> 00:00:34,041
Protect the Ocean podcast.
23
00:00:34,458 --> 00:00:36,125
Your weekday ocean news and insight
24
00:00:36,125 --> 00:00:38,166
podcast, where we connect the dots
25
00:00:38,250 --> 00:00:39,291
between science, policy
26
00:00:39,291 --> 00:00:41,666
and real world action.
27
00:00:42,208 --> 00:00:44,166
So if you want to understand how ocean
28
00:00:44,166 --> 00:00:46,500
management is done, how it really works,
29
00:00:46,750 --> 00:00:48,500
and not just the headlines, you want to
30
00:00:48,500 --> 00:00:50,250
follow this podcast on your favorite

00:00:51,458 --> 00:00:52,791
miss tomorrow's episode.
33
00:00:53,250 --> 00:00:54,166
At its core, fisheries
34
00:00:54,166 --> 00:00:55,833
management answers one question.
35
00:00:56,291 --> 00:00:57,583
How much can we fish
36
00:00:57,583 --> 00:00:59,625
without collapsing the population?
37
00:01:00,375 --> 00:01:02,750
You think that's a pretty big idea, and
38
00:01:02,750 --> 00:01:04,625
it's a very, a lot of pressure on that
39
00:01:04,625 --> 00:01:05,500
because we haven't
40
00:01:05,500 --> 00:01:06,583
really been doing a great job
41
00:01:06,875 --> 00:01:08,500
with many of the fisheries in the past.
42
00:01:09,041 --> 00:01:09,916
But to figure that out,
43
00:01:10,208 --> 00:01:11,291
scientists use stock assessments.
44
00:01:11,833 --> 00:01:13,750
These models estimate how the fish are,
45
00:01:14,041 --> 00:01:14,875
how many fish are in the
46
00:01:14,875 --> 00:01:16,666
ocean, how fast they reproduce,
47
00:01:17,083 --> 00:01:18,625
how much pressure they can handle.
48
00:01:19,416 --> 00:01:19,916
From there, they
49
00:01:19,916 --> 00:01:21,375
determine where a stock is,
50
00:01:21,375 --> 00:01:22,833
if it's healthy, being overfished,
51
00:01:22,833 --> 00:01:24,500
or even at risk of being overfished.
52
00:01:25,500 --> 00:01:27,000
Now, here's where it gets complicated.
53
00:01:27,958 --> 00:01:29,708
Tuna, they don't stay in one place.
54
00:01:30,666 --> 00:01:33,083
So instead of managing a local fishery,
55
00:01:33,083 --> 00:01:35,625
you're managing a shared global resource.
56
00:01:36,416 --> 00:01:38,666
Multiple countries, one population.
57
00:01:39,041 --> 00:01:41,250
That's where things start to break down.
58
00:01:41,458 --> 00:01:43,083
One of the things that I always talked
59
00:01:43,083 --> 00:01:44,916
about in my master's with my professor
60
00:01:45,416 --> 00:01:47,041
and my supervisor, he was always saying,
61
00:01:47,041 --> 00:01:47,666
"Hey, you know what?
62
00:01:48,041 --> 00:01:48,833
There are certain
63
00:01:48,833 --> 00:01:50,791
fisheries that we can manage within
64
00:01:51,208 --> 00:01:52,708
like a national boundary,
65
00:01:52,708 --> 00:01:54,125
an exclusive economic zone.
66
00:01:54,333 --> 00:01:55,291
And those fisheries are
67
00:01:55,291 --> 00:01:56,083
a little easier to manage
68
00:01:56,083 --> 00:01:58,375
because just one country, one population,
69
00:01:58,375 --> 00:01:59,583
maybe a couple of fisheries, different
70
00:01:59,583 --> 00:02:00,833
stock assessments and so forth.
71
00:02:01,166 --> 00:02:03,291
But the one country had the ability to
72
00:02:03,291 --> 00:02:04,416
enact its own rules on it.
73
00:02:04,416 --> 00:02:05,791
Now, some of those rules are great for
74
00:02:05,791 --> 00:02:06,416
different countries,
75
00:02:06,833 --> 00:02:07,791
and some of them are not so
76
00:02:07,791 --> 00:02:09,083
great for other countries.
77
00:02:09,666 --> 00:02:11,750
But they are able to manage it and makes
78
00:02:11,750 --> 00:02:13,208
it a little bit easier.
79
00:02:13,666 --> 00:02:14,916
When a fishery
80
00:02:14,916 --> 00:02:16,833
population goes over those borders
81
00:02:16,916 --> 00:02:17,666
outside the exclusive
82
00:02:17,666 --> 00:02:19,625
economic zone, like squid fishery,
83
00:02:19,916 --> 00:02:23,083
or they go all over the place or go into
84
00:02:23,083 --> 00:02:24,500
another country's
85
00:02:24,500 --> 00:02:25,791
exclusive economic zone,
86
00:02:25,791 --> 00:02:27,583
then you start to have to work in
87
00:02:27,583 --> 00:02:28,500
collaboration with other
88
00:02:28,500 --> 00:02:29,416
countries, other nations.
89
00:02:29,791 --> 00:02:30,041
Hopefully you're
90
00:02:30,041 --> 00:02:31,125
friendly with those nations.
91
00:02:31,791 --> 00:02:32,916
And when it goes to the high seas, it's
92
00:02:32,916 --> 00:02:33,708
even more difficult
93
00:02:33,708 --> 00:02:34,625
because there's really,
94
00:02:34,958 --> 00:02:36,166
other than the high seas treated, which
95
00:02:36,166 --> 00:02:37,166
is just enacted on
96
00:02:37,166 --> 00:02:39,583
January 17th of this year, 2026,
97
00:02:40,333 --> 00:02:42,375
there's really no process in place to
98
00:02:42,375 --> 00:02:44,000
protect those fisheries once
99
00:02:44,000 --> 00:02:45,458
it goes into the high seas.
100
00:02:46,125 --> 00:02:48,083
So it gets a little difficult and it gets
101
00:02:48,083 --> 00:02:48,708
a little complicated
102
00:02:48,958 --> 00:02:50,541
and starts to break down when we get to
103
00:02:50,541 --> 00:02:52,416
those positions and those processes.
104
00:02:53,416 --> 00:02:55,000
Now, here's the uncomfortable truth.
105
00:02:55,000 --> 00:02:57,541
The science has been there for decades.
106
00:02:57,541 --> 00:02:58,583
I've been saying that all week.
107
00:02:58,583 --> 00:03:00,083
The problem was never
108
00:03:00,083 --> 00:03:02,750
knowing what to do, how to act.
109
00:03:03,583 --> 00:03:05,958
The problem was actually doing the work
110
00:03:05,958 --> 00:03:08,250
and implementing the science, the
111
00:03:08,250 --> 00:03:10,166
guidance into the system.
112
00:03:10,375 --> 00:03:12,375
In global fisheries like tuna, decisions
113
00:03:12,375 --> 00:03:14,458
are made by international groups.
114
00:03:14,750 --> 00:03:16,708
Dozens of countries sit around the table.
115
00:03:17,125 --> 00:03:19,333
Scientists give advice, but countries
116
00:03:19,333 --> 00:03:21,958
negotiate and those negotiations often
117
00:03:21,958 --> 00:03:23,541
push limits higher than
118
00:03:23,541 --> 00:03:24,875
what the science recommends.
119
00:03:25,625 --> 00:03:27,625
Sometimes they don't agree at all.
120
00:03:27,916 --> 00:03:29,916
There are even cases where meetings
121
00:03:29,916 --> 00:03:32,166
happened over and over again and no
122
00:03:32,166 --> 00:03:34,166
decision was actually made, even when
123
00:03:34,166 --> 00:03:35,750
stocks were clearly in trouble.
124
00:03:36,250 --> 00:03:37,125
So the science says the
125
00:03:37,125 --> 00:03:37,958
stocks were in trouble.
126
00:03:37,958 --> 00:03:39,541
If they go over a certain amount of
127
00:03:39,541 --> 00:03:41,333
quota, then, you know, the
128
00:03:41,333 --> 00:03:42,541
stocks will be even more trouble,
129
00:03:42,750 --> 00:03:44,541
but then nobody really cared because they
130
00:03:44,541 --> 00:03:46,375
couldn't agree to an actual number, even
131
00:03:46,375 --> 00:03:48,625
though the number was there to be like,
132
00:03:48,625 --> 00:03:50,750
hey, if we fish at, say, 30,000 tons,
133
00:03:51,125 --> 00:03:53,375
then we can actually make sure that we do
134
00:03:53,375 --> 00:03:55,291
not overfish the population.
135
00:03:55,291 --> 00:03:56,833
I'm picking 30,000 tons out of the air.
136
00:03:57,625 --> 00:03:58,375
I don't know what the
137
00:03:58,375 --> 00:03:59,708
tons in here would be.
138
00:04:00,125 --> 00:04:01,208
However, it is very,
139
00:04:01,208 --> 00:04:02,458
it is very important.
140
00:04:03,000 --> 00:04:04,833
So the system wasn't being broken because
141
00:04:04,833 --> 00:04:05,375
of the lack of
142
00:04:05,375 --> 00:04:06,500
knowledge or the lack of data.
143
00:04:06,500 --> 00:04:08,333
It was broken because of how the
144
00:04:08,333 --> 00:04:10,000
decisions were actually made.
145
00:04:10,416 --> 00:04:11,708
And we've seen this time and time again.
146
00:04:11,708 --> 00:04:13,416
Yesterday's episode of you haven't been
147
00:04:13,416 --> 00:04:14,583
able to listen to it.
148
00:04:15,000 --> 00:04:16,666
You know, I talked about the cod fishery
149
00:04:16,666 --> 00:04:18,125
and how that was broken.
150
00:04:18,125 --> 00:04:19,000
That system was broken.
151
00:04:19,000 --> 00:04:20,208
The science said, hey,
152
00:04:20,500 --> 00:04:21,458
we're seeing a collapse.
153
00:04:21,458 --> 00:04:22,541
We're trying to see a decline and maybe
154
00:04:22,541 --> 00:04:25,000
even collapse coming for the cod fishery.
155
00:04:25,000 --> 00:04:26,125
Paul Disson is like, yeah, we're going to
156
00:04:26,125 --> 00:04:27,916
still negotiate above the quota level
157
00:04:27,916 --> 00:04:29,166
that that will make it sustainable.
158
00:04:29,750 --> 00:04:30,416
And then what happens?
159
00:04:30,416 --> 00:04:31,875
The collapse of the fisheries shifted the
160
00:04:31,875 --> 00:04:33,750
economics for the province of
161
00:04:33,750 --> 00:04:34,916
Newfoundland and other places.
162
00:04:35,541 --> 00:04:37,458
And it's just it hasn't really recovered.
163
00:04:38,000 --> 00:04:39,166
It just really hasn't.
164
00:04:39,458 --> 00:04:41,000
So that makes it very difficult.
165
00:04:41,958 --> 00:04:43,458
So what started to shift
166
00:04:43,458 --> 00:04:44,750
that made things change?
167
00:04:45,250 --> 00:04:47,291
It really was alignment groups like
168
00:04:47,291 --> 00:04:48,541
International Seafood Sustainability
169
00:04:48,541 --> 00:04:50,625
Foundation brought together
170
00:04:50,625 --> 00:04:52,875
scientists, industry and NGOs.
171
00:04:53,416 --> 00:04:55,375
And instead of competing voices, they
172
00:04:55,375 --> 00:04:56,666
created one unified push.
173
00:04:57,250 --> 00:04:59,458
Follow the frickin science.
174
00:04:59,916 --> 00:05:01,541
Right. Seems pretty easy.
175
00:05:02,083 --> 00:05:04,125
But believe you me, it is actually more
176
00:05:04,125 --> 00:05:05,625
complicated than you than you think
177
00:05:05,625 --> 00:05:06,541
because people don't
178
00:05:06,541 --> 00:05:07,708
want to listen to the data.
179
00:05:07,750 --> 00:05:10,125
The one thing about science is you may
180
00:05:10,125 --> 00:05:11,791
not like the results, but it's still the
181
00:05:11,791 --> 00:05:14,333
result and you have to follow the science
182
00:05:14,333 --> 00:05:16,000
or else you are going to get a worse
183
00:05:16,000 --> 00:05:18,583
result the next year or the decade later
184
00:05:18,583 --> 00:05:20,875
whenever you decide to sample or if you
185
00:05:20,875 --> 00:05:21,833
continue to sample and
186
00:05:21,833 --> 00:05:23,041
still not listen to the science.
187
00:05:23,666 --> 00:05:25,458
But more importantly, the groups backed
188
00:05:25,458 --> 00:05:27,250
up the follow the science action.
189
00:05:28,125 --> 00:05:29,208
Companies shared catch data.
190
00:05:30,166 --> 00:05:32,000
Retailers demanded sustainable sourcing.
191
00:05:32,541 --> 00:05:33,208
The fisheries started
192
00:05:33,208 --> 00:05:34,708
pushing for better management.
193
00:05:35,208 --> 00:05:36,041
This wasn't about
194
00:05:36,041 --> 00:05:37,291
necessarily being louder.
195
00:05:37,625 --> 00:05:38,458
It was about being
196
00:05:38,458 --> 00:05:40,125
consistent and credible.
197
00:05:40,625 --> 00:05:42,625
And when pressure comes from every part
198
00:05:42,625 --> 00:05:44,833
of the system, not just one, governments
199
00:05:44,833 --> 00:05:46,041
have to start to respond.
200
00:05:46,625 --> 00:05:47,833
And they do. And they did.
201
00:05:48,291 --> 00:05:49,666
Then came the biggest shift.
202
00:05:50,208 --> 00:05:51,083
Harvest strategies, which
203
00:05:51,083 --> 00:05:51,958
we talked about yesterday.
204
00:05:52,708 --> 00:05:53,750
If you don't know about harvest
205
00:05:53,750 --> 00:05:54,750
strategies, listen to
206
00:05:54,750 --> 00:05:55,541
the episode yesterday.
207
00:05:55,541 --> 00:05:56,500
We talked a lot about it.
208
00:05:56,875 --> 00:05:58,166
Before this, fisheries were
209
00:05:58,166 --> 00:05:58,708
managed pretty reactively.
210
00:05:58,875 --> 00:06:02,625
Every year meant new negotiations, new
211
00:06:02,625 --> 00:06:04,333
debates, new delays and harvest
212
00:06:04,333 --> 00:06:06,208
strategies flipped that right.
213
00:06:06,208 --> 00:06:08,500
They came up with a pre agreed rules.
214
00:06:08,875 --> 00:06:10,958
If stock declines, we reduce fishing.
215
00:06:11,500 --> 00:06:13,125
If it grows, we increase fishing.
216
00:06:13,541 --> 00:06:14,625
No debate in the moment.
217
00:06:15,250 --> 00:06:16,208
No political delay.
218
00:06:16,708 --> 00:06:18,583
Just a system that responds
219
00:06:18,583 --> 00:06:20,916
automatically based on science.
220
00:06:20,916 --> 00:06:23,166
That's pretty powerful because it removes
221
00:06:23,166 --> 00:06:25,916
short term decision making and replaces
222
00:06:25,916 --> 00:06:26,708
it with long term planning.
223
00:06:26,750 --> 00:06:29,375
And at the same time, the
224
00:06:29,375 --> 00:06:30,666
market started to change.
225
00:06:31,541 --> 00:06:33,333
Right. Certification programs like the
226
00:06:33,333 --> 00:06:35,666
Marine Stewardship Council raised the bar
227
00:06:35,666 --> 00:06:37,833
to sell into major markets.
228
00:06:38,291 --> 00:06:40,500
Fisheries needed healthy stocks, science
229
00:06:40,500 --> 00:06:42,416
based management and harvest strategies.
230
00:06:42,625 --> 00:06:43,583
They needed those rules.
231
00:06:44,583 --> 00:06:45,750
So fisheries had a choice.
232
00:06:45,750 --> 00:06:48,500
They could adapt or lose access and they
233
00:06:48,500 --> 00:06:51,416
adapted fishing vessels also stepped up
234
00:06:51,416 --> 00:06:53,625
adopting bycatch reduction techniques,
235
00:06:54,000 --> 00:06:55,500
monitoring systems, voluntary
236
00:06:55,500 --> 00:06:56,708
sustainability, maintenance, and so forth.
237
00:06:56,708 --> 00:06:58,791
And here's the key.
238
00:06:59,625 --> 00:07:01,125
Even one improvement matter.
239
00:07:01,791 --> 00:07:03,750
So because there when hundreds of vessels
240
00:07:03,750 --> 00:07:05,791
each did their own thing, we started to
241
00:07:05,791 --> 00:07:06,708
see them doing better.
242
00:07:07,000 --> 00:07:09,375
The system changed fast because everybody
243
00:07:09,375 --> 00:07:10,333
was doing something.
244
00:07:10,958 --> 00:07:12,000
And that's a big thing.
245
00:07:12,000 --> 00:07:13,708
Even if it was just one thing, there were
246
00:07:13,708 --> 00:07:14,791
multiple measures they could take.
247
00:07:14,791 --> 00:07:16,666
But even if they did one thing at the
248
00:07:16,666 --> 00:07:18,708
minimum, things changed because there
249
00:07:18,708 --> 00:07:19,833
were so many vessels involved.
250
00:07:20,583 --> 00:07:21,750
So why does all of this
251
00:07:21,750 --> 00:07:23,083
matter in this episode?
252
00:07:23,083 --> 00:07:24,166
I've talked about it all week.
253
00:07:24,375 --> 00:07:25,125
Why does it all matter?
254
00:07:26,708 --> 00:07:26,916
Because it's a very important thing.
255
00:07:27,041 --> 00:07:29,125
We don't hear enough about fisheries
256
00:07:29,125 --> 00:07:31,083
management can actually work.
257
00:07:31,958 --> 00:07:34,666
Not perfectly, not everywhere, but it can
258
00:07:34,666 --> 00:07:37,416
work when science is trusted.
259
00:07:38,041 --> 00:07:40,750
Data shared incentives are aligned and
260
00:07:40,750 --> 00:07:42,041
decisions aren't delayed.
261
00:07:42,666 --> 00:07:44,458
And tomorrow we're going to look at what
262
00:07:44,458 --> 00:07:47,250
happens when all of that comes together
263
00:07:47,250 --> 00:07:48,625
because the results
264
00:07:48,625 --> 00:07:50,500
might actually surprise you.
265
00:07:51,041 --> 00:07:52,458
Now, this isn't a
266
00:07:52,458 --> 00:07:53,708
perfect system by any means.
267
00:07:53,750 --> 00:07:55,958
There's going to be gaps of monitoring
268
00:07:55,958 --> 00:07:57,666
and enforcement, data limitations,
269
00:07:58,000 --> 00:08:00,041
observer coverage and climate impacts are
270
00:08:00,041 --> 00:08:02,833
all going to have a say in what happens.
271
00:08:03,500 --> 00:08:05,000
And the next step is even bigger.
272
00:08:05,291 --> 00:08:05,916
Moving towards
273
00:08:05,916 --> 00:08:07,500
ecosystem based management.
274
00:08:08,041 --> 00:08:09,083
Looking at the entire
275
00:08:09,083 --> 00:08:11,708
ecosystem, not just one species.
276
00:08:12,791 --> 00:08:14,708
That's where this is heading and it's
277
00:08:14,708 --> 00:08:16,000
heading in a good in a
278
00:08:16,000 --> 00:08:17,416
good way, in a good direction.
279
00:08:18,125 --> 00:08:19,458
If there's one thing to take away from
280
00:08:19,458 --> 00:08:20,708
this episode today, it's this.
281
00:08:21,291 --> 00:08:23,458
We don't have a
282
00:08:23,458 --> 00:08:24,500
knowledge problem in fisheries.
283
00:08:25,083 --> 00:08:26,958
We have an implementation problem and
284
00:08:26,958 --> 00:08:27,583
when implementation
285
00:08:27,583 --> 00:08:29,625
improves outcomes improve.
286
00:08:30,666 --> 00:08:31,625
It's really not that
287
00:08:31,625 --> 00:08:33,500
difficult from a process standpoint.
288
00:08:34,416 --> 00:08:35,125
And tomorrow we're going to look at
289
00:08:35,125 --> 00:08:37,625
exactly how far that improvement has gone
290
00:08:37,625 --> 00:08:40,250
with tuna fisheries and what it means for
291
00:08:40,250 --> 00:08:41,666
the future of ocean conservation.
292
00:08:42,041 --> 00:08:43,333
I want to thank you for listening to this
293
00:08:43,333 --> 00:08:44,375
episode of the how to
294
00:08:44,375 --> 00:08:45,166
protect the ocean podcast.
295
00:08:45,666 --> 00:08:48,000
Make sure that you follow the show so you
296
00:08:48,000 --> 00:08:48,708
don't miss tomorrow's episode.
297
00:08:48,708 --> 00:08:56,458
It's a really important episode where we both have a lot of fun. And if you know someone who thinks
298
00:08:56,458 --> 00:08:58,583
fisheries management never works, share
299
00:08:58,583 --> 00:09:00,500
this episode with them because the ocean
300
00:09:00,500 --> 00:09:02,166
needs more people who
301
00:09:02,166 --> 00:09:04,833
understand what is actually possible.
302
00:09:05,208 --> 00:09:06,416
I want to thank you for joining me on
303
00:09:06,416 --> 00:09:07,500
today's episode of the how
304
00:09:07,500 --> 00:09:08,625
to protect the ocean podcast.
305
00:09:08,625 --> 00:09:09,458
I'm your host, Andrew.
306
00:09:09,458 --> 00:09:11,000
Have a great day. We'll talk to you
307
00:09:11,000 --> 00:09:12,625
tomorrow and happy conservation.
