The Pacific bluefin tuna population has seen a significant increase in the number of female tuna capable of reproductive success, indicating a successful conservation effort. The recent stock assessment revealed a substantial rise in the population of female Pacific bluefin tuna able to reproduce, showing that international efforts to protect and manage the species have been effective in reversing the decline and promoting population growth.

This success story highlights the severe threats faced by the Pacific bluefin tuna population due to overfishing, with the stock plummeting by over 96% from its historic high. Despite these challenges, there has been a notable turnaround in the population status, particularly in increasing the number of reproductive females, a crucial milestone in the conservation of this species.

The conservation success of the Pacific bluefin tuna demonstrates that with dedicated efforts and effective management strategies, it is possible to reverse the decline of marine species and promote their recovery. The increase in the number of reproductive females is a positive sign for the future sustainability of the Pacific bluefin tuna population.

The significant rise in the number of female Pacific bluefin tuna capable of reproductive success showcases the effectiveness of conservation efforts and emphasizes the importance of continued collaboration and conservation measures to ensure the long-term survival of this iconic species.

The overfishing of Pacific bluefin tuna had devastating consequences, leading to a staggering 96% drop in population from its historic high. This drastic decline highlighted the urgent need for immediate and effective conservation measures to prevent the species from facing extinction. The episode discusses how a scientific report in 2012 revealed the alarming state of the Pacific bluefin tuna population, emphasizing the severe impact of overfishing on the species.

The significant decrease in the Pacific bluefin tuna population served as a wake-up call, indicating that urgent action was required to reverse the trend of depletion. The episode mentions how the exploitation of these large and valuable fish for commercial purposes, such as the celebratory auction where a Japanese sushi chain purchased a bluefin tuna for $1.7 million, demonstrated how financial interests often outweighed conservation concerns.

The episode also touches upon the slow growth and long lifespan of tuna species, making their recovery a lengthy and challenging process. The conservation success story of the Pacific bluefin tuna serves as a beacon of hope, showcasing that with coordinated international efforts and effective management strategies, it is possible to reverse the decline of overexploited marine species. This success story underscores the importance of implementing sustainable fishing practices and conservation measures to protect vulnerable marine species like the Pacific bluefin tuna.

The episode highlights the exploitation of endangered tuna species by corporations for profit, noting how the value of individual tuna species can increase as they become more endangered. This phenomenon occurs because the scarcity of a species drives up its market value, making each individual catch more lucrative for those involved in the fishing industry.

In the case of the Pacific bluefin tuna, despite facing a significant decline in population due to overfishing, there were instances where a Japanese sushi chain purchased a bluefin tuna for a staggering $1.7 million in a celebratory auction. This exorbitant price tag demonstrates how the demand for these endangered species can lead to inflated prices, creating a financial incentive for exploitation.

Furthermore, the episode mentions a common practice where corporations catch endangered tuna species, freeze them for extended periods, and then sell them at a higher price when the species is on the brink of extinction. This strategy essentially turns the exploitation of endangered species into an investment opportunity for these corporations, prioritizing short-term profits over the long-term sustainability of marine ecosystems.

The documentary "End of the Line," referenced in the episode, provides further insight into the exploitation of tuna species for profit. It delves into the practices of the tuna industry in various regions, shedding light on the detrimental impact of overfishing and the commodification of endangered species.

Overall, the episode underscores the alarming trend where the increasing rarity of certain tuna species can paradoxically drive their commercial value up, leading to their exploitation by corporations solely for financial gain. This highlights the urgent need for robust conservation measures and sustainable fishing practices to protect these vulnerable marine species from further exploitation and potential extinction.

I am so happy that you tuned into this episode because it's not

2
00:00:03,493 --> 00:00:06,517
every day that I get to talk about a

3
00:00:06,617 --> 00:00:09,961
conservation success story. There have been many conservation success

4
00:00:10,001 --> 00:00:13,606
stories over the period of marine conservation. However,

5
00:00:14,489 --> 00:00:17,831
it's not often that we get these wins and today we're going to be talking about

6
00:00:17,931 --> 00:00:21,132
the pacific bluefin tuna because there's been a

7
00:00:21,272 --> 00:00:25,574
huge international coordinated effort to bring the species

8
00:00:25,814 --> 00:00:29,276
back from the brink of extinction to something that

9
00:00:29,396 --> 00:00:32,757
could actually be seen as a population that is growing and we've actually

10
00:00:32,877 --> 00:00:36,419
hit that day there's been a recent stock assessment that shows that

11
00:00:36,439 --> 00:00:40,281
there's been a huge increase in the number of female Pacific

12
00:00:40,301 --> 00:00:43,942
bluefin tuna that can have reproductive success, and

13
00:00:43,962 --> 00:00:48,104
it shows that we can actually turn a lot of

14
00:00:48,644 --> 00:00:52,105
tuna species around from bad management in

15
00:00:52,145 --> 00:00:55,847
the past very quickly. In fact, 10 years earlier than

16
00:00:55,927 --> 00:00:59,069
we expected for this Pacific bluefin tuna. talk about this

17
00:00:59,109 --> 00:01:02,595
conservation success story, what happened, why it became such

18
00:01:02,635 --> 00:01:05,921
a story, and what happened really to understand that, hey,

19
00:01:05,981 --> 00:01:09,146
this species was in trouble. We're gonna talk about that on

20
00:01:09,166 --> 00:01:12,311
today's episode of the How to Protect the Ocean podcast. Let's start the

21
00:01:12,331 --> 00:01:17,436
show. Hey

22
00:01:17,456 --> 00:01:20,939
everybody, welcome back to another exciting episode of the How to Protect the Ocean podcast. I'm

23
00:01:20,959 --> 00:01:24,302
your host Andrew Lewin and this is the podcast where you find out what's happening with the ocean,

24
00:01:24,362 --> 00:01:27,785
how you can speak up for the ocean, what you can do to live for a better ocean

25
00:01:28,265 --> 00:01:31,768
by taking action. And today we're going to be talking about that action taking

26
00:01:32,428 --> 00:01:35,791
by government and by a number of governments, international governments.

27
00:01:36,051 --> 00:01:39,772
Now, when we talk about the Pacific tuna, the bluefin tuna,

28
00:01:40,152 --> 00:01:43,393
we talk about a species that goes across borders. This

29
00:01:43,453 --> 00:01:46,554
is not a species that just understands that there are

30
00:01:46,574 --> 00:01:50,134
U.S., Canadian, and international borders. They stay within those national

31
00:01:50,174 --> 00:01:53,235
boundaries so that they can get better protected. No, no, no, no. This is

32
00:01:53,275 --> 00:01:56,956
a species that goes, it starts off in the Sea of Japan. all

33
00:01:56,976 --> 00:02:00,197
the way in between japan and the philippines where they're where they're bred and they're

34
00:02:00,217 --> 00:02:03,638
born and then they come over to like the baja

35
00:02:03,658 --> 00:02:07,219
california mexico area and then they go back after

36
00:02:07,259 --> 00:02:10,460
a year and where they feed and stuff and go back for six

37
00:02:10,760 --> 00:02:13,881
six thousand mile trek across the pacific and

38
00:02:13,921 --> 00:02:18,183
they do it in like 55 days because they're incredible swimmers And

39
00:02:18,423 --> 00:02:21,625
it's great to see a species like this that

40
00:02:21,685 --> 00:02:24,766
is highly sought after for food rebound the

41
00:02:24,826 --> 00:02:28,048
way it has. And that's what we're going to be talking about today. It's going to be the focus. Because

42
00:02:28,088 --> 00:02:31,290
I came across this article on LinkedIn. I'm very active on

43
00:02:31,330 --> 00:02:34,912
LinkedIn. So if you ever want to hit me up on LinkedIn, please do so. I

44
00:02:34,952 --> 00:02:38,434
came across this article. It's a LinkedIn article by

45
00:02:38,574 --> 00:02:42,095
Jamie Gibbon, who is a manager of international fisheries

46
00:02:42,295 --> 00:02:45,897
at the Pew Charitable Trust. And it caught my eye because

47
00:02:45,957 --> 00:02:50,239
he talks about the Pacific bluefin tuna, a decade-long conservation

48
00:02:50,259 --> 00:02:53,660
success. And he links to another NOAA article that

49
00:02:53,700 --> 00:02:57,582
talks about how it went from overfish to a sustainable success

50
00:02:57,602 --> 00:03:01,105
story. But Jamie's talk he starts off his article really

51
00:03:01,245 --> 00:03:05,089
in an interesting way he talks about like how working in conservation can

52
00:03:05,169 --> 00:03:08,693
sometimes feel like an endless slog filled with both

53
00:03:08,793 --> 00:03:12,437
victories and frustrating setbacks and focusing on international fisheries

54
00:03:12,997 --> 00:03:17,021
which have been doing for over which he's been doing for over a decade can

55
00:03:17,061 --> 00:03:20,782
make everything feel like it's more drawn out. High seas

56
00:03:20,822 --> 00:03:24,443
fisheries are very valuable, worth tens of billions of dollars a

57
00:03:24,523 --> 00:03:27,744
year, and so there's a constant pressure to increase the amount

58
00:03:27,764 --> 00:03:31,004
of fish that can be caught, but management decisions are usually

59
00:03:31,144 --> 00:03:34,385
only made once a year. So if the progress isn't met

60
00:03:34,585 --> 00:03:38,266
after that one year, you have to wait an entire 12-month cycle

61
00:03:38,346 --> 00:03:41,507
to get your management priorities in place for the next

62
00:03:41,547 --> 00:03:44,967
year, and if it's not in there, It's not great. So that can help

63
00:03:45,047 --> 00:03:48,848
build overfish stocks. Tuna and sharks grow relatively slowly

64
00:03:51,289 --> 00:03:54,610
and live a relatively long time. So recovery can feel like it takes

65
00:03:54,710 --> 00:03:58,651
forever. But that's why this is interesting, because back

66
00:03:58,831 --> 00:04:01,991
in 2012, as Jamie reports, a

67
00:04:02,051 --> 00:04:05,392
scientific report showed that the population of Pacific bluefin tuna had

68
00:04:05,452 --> 00:04:08,693
been decimated by overfishing, which the

69
00:04:08,713 --> 00:04:13,414
stock dropped over 96% from its historic high. But

70
00:04:13,574 --> 00:04:17,056
that didn't stop a Japanese sushi chain from buying

71
00:04:17,076 --> 00:04:21,378
the bluefin tuna caught the next year for $1.7 million

72
00:04:21,478 --> 00:04:24,660
in a celebratory auction. You gotta

73
00:04:24,720 --> 00:04:28,582
remember that this species is large. When

74
00:04:28,622 --> 00:04:32,204
you get one particular species, they could weigh

75
00:04:32,464 --> 00:04:35,926
up to 1,000 pounds. And they're huge,

76
00:04:35,946 --> 00:04:39,207
they're like 10 feet in length. So they are big species, they

77
00:04:39,227 --> 00:04:43,030
are big fish. So buying something for $1.7 million

78
00:04:43,170 --> 00:04:46,492
is a huge, huge win. So with that decision,

79
00:04:46,532 --> 00:04:49,674
though, everything was going wrong for the species, showing that the

80
00:04:49,774 --> 00:04:53,176
money was outweighing the need for conservation. And

81
00:04:53,196 --> 00:04:57,519
in fact, with a lot of tuna species, the imminent

82
00:04:57,539 --> 00:05:04,503
decision or the imminent likelihood of you

83
00:05:04,543 --> 00:05:07,846
know, these species going extinct, that could go extinct, kind

84
00:05:07,906 --> 00:05:11,088
of increase their value of each individual species that's caught, or each

85
00:05:11,128 --> 00:05:14,370
individual of that species that's caught. You know, so

86
00:05:14,630 --> 00:05:18,293
a lot of places, a lot of corporations would catch these tuna,

87
00:05:18,854 --> 00:05:22,136
freeze them for a long time, for like 20 years or so, and sell them down

88
00:05:22,196 --> 00:05:25,418
the line when they know that they're gonna be extinct for more money. It's just

89
00:05:25,438 --> 00:05:28,521
an investment for a lot of these corporations. If you don't know what

90
00:05:28,541 --> 00:05:31,703
I'm talking about, watch End of the Line, It is an

91
00:05:32,263 --> 00:05:35,425
impeccable documentary that is narrated by

92
00:05:35,505 --> 00:05:39,107
Ted Danson, who's involved with Oceana, and they talk about

93
00:05:39,147 --> 00:05:43,449
the tuna industry in general, and you get a feel for what the tuna

94
00:05:43,569 --> 00:05:47,091
industry goes through in Europe, in the Mediterranean, in
