Most seafood labels look simple, but they often hide more than they reveal.

When you buy fish at a grocery store, the package might say salmon, tuna, or cod. But those market names can represent dozens of different species, and the label rarely tells you exactly which one you are eating. In many cases, key details like the fishing location, the vessel that caught the fish, or the specific species are missing.

In this episode of How to Protect the Ocean, we explore the seafood labeling gap and why it matters. When multiple species are grouped under the same market name, it becomes harder to detect seafood fraud, track fisheries, and ensure sustainable seafood choices. Understanding what labels do and do not tell us is an important step toward improving transparency in the global seafood supply chain.

00:00:00,000 --> 00:00:03,235
When you buy seafood at the grocery store,
the label might say something simple.

2
00:00:03,275 --> 00:00:05,125
Salmon, tuna, cod.

3
00:00:05,505 --> 00:00:09,265
But those labels often hide more
information than they reveal.

4
00:00:09,415 --> 00:00:14,455
In many cases, consumers have almost
no idea what species they're actually

5
00:00:14,455 --> 00:00:18,808
eating or where it came from, and
that lack of transparency has become a

6
00:00:18,808 --> 00:00:21,658
major issue in global seafood markets.

7
00:00:21,915 --> 00:00:25,358
This is the How to Protect the Ocean
Podcast, your weekday Ocean news update.

you don't miss tomorrow's story.

10
00:00:33,062 --> 00:00:37,232
So the key question today is what
information do seafood labels actually

11
00:00:37,232 --> 00:00:40,262
provide, and what information is missing?

12
00:00:40,322 --> 00:00:41,882
That's really the question here.

13
00:00:42,225 --> 00:00:45,222
So, seafood labeling rules
vary widely in the world.

14
00:00:45,472 --> 00:00:49,265
In major markets, labels include only
a few pieces of basic information.

15
00:00:49,535 --> 00:00:52,205
May have like a common market
name, so what you know, cod,

16
00:00:52,205 --> 00:00:53,795
salmon, tuna, that kind of stuff.

17
00:00:53,855 --> 00:00:57,725
The country of origin and whether
the seafood was farmed or wild cod.

18
00:00:57,963 --> 00:01:02,223
But in many cases, the labels don't
include the exact scientific species

19
00:01:02,223 --> 00:01:03,693
name, which is really, really important.

20
00:01:03,693 --> 00:01:04,683
We'll talk about that in a second.

21
00:01:04,850 --> 00:01:07,377
The catch location or the fishing area?

22
00:01:07,580 --> 00:01:11,840
The fishing method used, and the vessel,
or the fleet that it was caught in.

23
00:01:11,840 --> 00:01:16,373
So even just like the registration
flag where this vessel was registered.

24
00:01:16,583 --> 00:01:20,653
Without this information, it becomes
difficult for consumers to understand

25
00:01:20,653 --> 00:01:22,213
what they're actually buying.

26
00:01:22,527 --> 00:01:27,147
And the issue becomes even more
complicated because many market names

27
00:01:27,147 --> 00:01:29,113
represent multiple different species.

28
00:01:29,359 --> 00:01:32,749
For example, the label snapper
can represent more than 60

29
00:01:32,749 --> 00:01:34,189
different species worldwide.

30
00:01:34,219 --> 00:01:38,439
60. The label tuna can refer
to several species with very

31
00:01:38,439 --> 00:01:40,059
different population statuses.

32
00:01:40,249 --> 00:01:44,409
The term rockfish includes dozens
of species of the Genus Sybaris.

33
00:01:44,682 --> 00:01:47,556
Some of these species are
abundant, others are heavily

34
00:01:47,796 --> 00:01:49,656
fished or under strict management.

35
00:01:50,182 --> 00:01:53,092
But when they're grouped under one
simple in the market name, consumers

36
00:01:53,092 --> 00:01:54,622
cannot easily tell the difference.

37
00:01:54,622 --> 00:01:55,222
It's really difficult.

38
00:01:55,752 --> 00:01:58,242
Knowing the scientific species
name, you can actually get

39
00:01:58,242 --> 00:01:59,382
what the common names are.

40
00:01:59,382 --> 00:02:03,232
So you'll have one species name, which
is like a Latin name, and once you have

41
00:02:03,232 --> 00:02:06,422
that Latin name, it'll list all the
different, like if I search up Latin

42
00:02:06,422 --> 00:02:09,926
names in ChatGPT, or even on Google
or Gemini, whatever that might be.

43
00:02:10,079 --> 00:02:11,529
I don't know what we're
searching in these days.

44
00:02:12,129 --> 00:02:15,099
If I search a scientific name, you'll get
all the common names that they're commonly

45
00:02:15,099 --> 00:02:18,119
referred to and you'll see that there are
multiple common names and that just could

46
00:02:18,119 --> 00:02:19,616
mean the different parts of the world.

47
00:02:19,726 --> 00:02:20,822
Different countries are found.

48
00:02:20,926 --> 00:02:23,342
They might have like a Spanish name,
they might have an English name.

49
00:02:23,492 --> 00:02:25,532
Even within an English name
they'll be called different things

50
00:02:25,532 --> 00:02:26,729
or known for different things.

51
00:02:26,872 --> 00:02:30,142
So just having a common name
doesn't necessarily mean that you're

52
00:02:30,142 --> 00:02:32,616
eating the species you think you're
eating, but having that scientific

53
00:02:32,616 --> 00:02:34,472
name really brings it to that area.

54
00:02:34,696 --> 00:02:38,982
Also, the vessel or fleet that caught
the fish, making sure that you know

55
00:02:39,012 --> 00:02:42,792
what country that vessel or fleet we're
registered to is really important.

56
00:02:42,792 --> 00:02:46,362
'cause that will tell you whether
that country is known for good

57
00:02:46,362 --> 00:02:49,159
fisheries practices or not
so good fisheries practices.

58
00:02:49,279 --> 00:02:53,869
Some countries are known for not
regulating or not managing the illegal,

59
00:02:53,869 --> 00:02:55,909
unregulated, and unreported fisheries.

60
00:02:55,909 --> 00:02:59,689
So IUU fishing, which is a big
problem when we look at overfishing.

61
00:02:59,866 --> 00:03:02,236
And so some countries have a
really bad reputation for that.

62
00:03:02,521 --> 00:03:04,051
Others have a really good reputation.

63
00:03:04,051 --> 00:03:07,567
So a lot of the vessels will register
under the countries that do not have a

64
00:03:07,567 --> 00:03:11,261
good reputation for it, because it's
easier to get away with IUU fishing.

65
00:03:11,381 --> 00:03:11,741
You get it?

66
00:03:11,801 --> 00:03:13,027
So that's how it really works.

67
00:03:13,207 --> 00:03:14,557
So what does the science say?

68
00:03:14,754 --> 00:03:18,294
Researchers studying seafood supply
chains have repeatedly found that

69
00:03:18,294 --> 00:03:22,344
the lack of species level labeling
creates major transparency gaps.

70
00:03:22,537 --> 00:03:25,387
A global analysis of seafood
labeling and traceability found

71
00:03:25,387 --> 00:03:29,027
that the seafood products often
pass through multiple intermediates.

72
00:03:29,184 --> 00:03:32,557
So including processors,
distributors, and wholesalers

73
00:03:32,611 --> 00:03:34,111
before reaching consumers.

74
00:03:34,141 --> 00:03:37,301
In some cases, after the fishers
catch the fish, they give it to

75
00:03:37,301 --> 00:03:39,117
somebody like, give it to a company.

76
00:03:39,274 --> 00:03:41,701
And they actually don't know
where their product is sold.

77
00:03:41,924 --> 00:03:45,404
That's been documented a number of times,
especially there was one place in North

78
00:03:45,404 --> 00:03:48,314
Carolina where it was documented, where
the fishers didn't know where it went.

79
00:03:48,531 --> 00:03:51,651
It got handed off a number of different
times and it would end up in New York or

80
00:03:51,651 --> 00:03:53,246
end up in Seattle, or end up anywhere.

81
00:03:53,452 --> 00:03:55,317
But they had no idea who
was buying their fisheries.

82
00:03:55,317 --> 00:03:59,074
That's why a lot of fishers that are
local have gone to local catch shares

83
00:03:59,074 --> 00:04:02,546
where people pay into a program and
they will get certain fish out of that,

84
00:04:02,546 --> 00:04:05,012
they'll get a certain amount of fish out
of that, depending on how much they pay.

85
00:04:05,122 --> 00:04:08,229
So like if they have a catch
share and you pay like $200, you

86
00:04:08,229 --> 00:04:09,816
may get $200 worth of fish.

87
00:04:09,959 --> 00:04:12,669
The Fisher knows who it's
going to locally, which is

88
00:04:12,669 --> 00:04:13,746
really great for the fisher.

89
00:04:13,906 --> 00:04:15,796
And the consumer knows who caught it.

90
00:04:15,916 --> 00:04:17,472
They know their families,
they know everything.

91
00:04:17,576 --> 00:04:19,946
And it's kind of nice to
have that, that relationship.

92
00:04:19,946 --> 00:04:21,422
It kind of brings it back home.

93
00:04:21,616 --> 00:04:23,656
It kind of brings pride
back into the Fishers.

94
00:04:23,656 --> 00:04:24,376
I'm not a fisher.

95
00:04:24,446 --> 00:04:28,166
But I know fishermen and fishing
communities have a lot of pride in their

96
00:04:28,166 --> 00:04:32,062
work, and I'm sure they would wanna see
it go to people that they know and that

97
00:04:32,062 --> 00:04:33,507
they can know will enjoy their fish.

98
00:04:33,972 --> 00:04:37,392
So at each step of the supply chain,
information about species identity

99
00:04:37,392 --> 00:04:41,966
or catch origin can be lost or
simplified into these broad categories.

100
00:04:42,162 --> 00:04:45,509
So another study examined seafood
labeling in North America and found

101
00:04:45,509 --> 00:04:49,002
that market names frequently group
multiple species together, making

102
00:04:49,002 --> 00:04:52,872
it difficult for buyers to know
exactly where they were purchasing.

103
00:04:53,169 --> 00:04:55,089
This is not necessarily illegal.

104
00:04:55,299 --> 00:05:00,276
In many cases, it is simply how seafood
regulations were designated decades ago.

105
00:05:00,499 --> 00:05:03,039
But the result is a
marketplace where species level

106
00:05:03,039 --> 00:05:05,349
transparency is often missing.

107
00:05:05,582 --> 00:05:09,482
A solution to that is to update these
regulations, update the marketplace,

108
00:05:09,552 --> 00:05:13,162
making sure that transparency is
forward thinking in the policy,

109
00:05:13,162 --> 00:05:14,557
in the regulations, in the law.

110
00:05:15,084 --> 00:05:17,094
So why does this matter?

111
00:05:17,224 --> 00:05:20,794
Why do we care from a consumer's point
of view, from my point of view, like

112
00:05:20,794 --> 00:05:24,537
why am I telling you why labeling is
important and a lack of information

113
00:05:24,537 --> 00:05:26,137
labeling is not a good thing?

114
00:05:26,401 --> 00:05:29,251
When seafood is sold under broad
market names instead of specific

115
00:05:29,251 --> 00:05:31,547
species, several problems emerge.

116
00:05:31,667 --> 00:05:34,311
First, it becomes harder
to detect seafood fraud.

117
00:05:34,514 --> 00:05:36,914
If you have the transparency, you know
the species, you know where it's gone

118
00:05:36,914 --> 00:05:40,974
throughout the entire supply chain, it's
really hard to sell fraudulent seafood

119
00:05:40,974 --> 00:05:42,774
or even pass on fraudulent seafood.

120
00:05:43,061 --> 00:05:46,601
Second, fisheries managers have more
difficulty tracking which species

121
00:05:46,601 --> 00:05:48,336
are actually being sold and consumed.

122
00:05:48,892 --> 00:05:53,152
And third, consumers who want to make
sustainable seafood choices often do

123
00:05:53,152 --> 00:05:54,706
not have the information they need.

124
00:05:54,896 --> 00:05:58,346
A great example is anytime I go to the
supermarket and I ask the person behind

125
00:05:58,346 --> 00:06:01,496
the counter, and usually it's like,
you know, something like a teenager

126
00:06:01,496 --> 00:06:04,536
or someone who's just trying to get
their job, trying to get their pay.

127
00:06:04,536 --> 00:06:06,996
Whether it's minimum wage as
a student or student wage, or

128
00:06:06,996 --> 00:06:08,436
somebody else's been there forever.

129
00:06:08,509 --> 00:06:11,069
If they don't know much about the fish,
they don't know where it came from,

130
00:06:11,069 --> 00:06:15,427
how it was caught, where it was caught,
it makes the process really difficult.

131
00:06:15,647 --> 00:06:18,537
And to be honest, it shouldn't be
up to the person behind the counter.

132
00:06:18,741 --> 00:06:22,611
It should be up to the labels
that are on the actual packaging.

133
00:06:22,864 --> 00:06:26,311
So, for example, two fish labeled
as tuna may come from completely

134
00:06:26,311 --> 00:06:29,401
different fisheries and completely
different geographies with very

135
00:06:29,401 --> 00:06:30,931
different environmental impacts.

136
00:06:31,154 --> 00:06:34,154
But the label does not
always reveal the difference.

137
00:06:34,411 --> 00:06:37,111
This lack of transparency
creates blind spots across the

138
00:06:37,111 --> 00:06:38,881
entire seafood supply chain.

139
00:06:39,201 --> 00:06:41,871
Tomorrow we're gonna look at how
scientists discovered that seafood

140
00:06:41,871 --> 00:06:44,271
labels are sometimes not just vague.

141
00:06:44,541 --> 00:06:45,684
They're just sometimes wrong.

142
00:06:45,931 --> 00:06:49,057
DNA testing has revealed
widespread seafood mislabeling

143
00:06:49,057 --> 00:06:50,677
in markets around the world.

144
00:06:50,677 --> 00:06:53,804
We're going to really dive deep
into fraud and the results,

145
00:06:53,804 --> 00:06:54,974
it may surprise you.
