Endangered Eating

Check out this great blog post from Eating . . . Our Words, a blog hosted by Houston Press. It details ten species of endangered fish that are still commonly eaten, and asks the question "Why are we still eating species that are on the verge of collapse?"

10 Fish You're Eating That Are Endangered Species

Here's a list of different organizations and advisories focusing on sustainable seafood choices.

Bluefin Blues

Northern Bluefin Tuna (Thunnus Thynnus), Critically Endangered

I'm in Japan for my brother's wedding, and I almost cried. Not because of the wedding. Because of the Bluefin Tuna.



The Bluefin Tuna, known in Japan as Hone Maguro, is prized as a delicious morsel of sushi and is extremely popular. I went down to the Tsukiji Fish Market in Tokyo, the largest wholesale seafood market in the world, two days ago, hoping to get a glimpse of the auction where the Tuna are sold. The Tuna auction (and the entire wholesale portion of the market) was closed to tourists, so my family and I snuck in. Walking past aisle upon aisle of Shellfish, Molluscs, and hundreds of Fish species, I was appalled to see a sign for a booth selling Whale. My mother reminded me that fishing was in my heritage (I'm half Japanese), and I felt ashamed.

Though I only managed to get a few glimpses and blurry photographs of the rows of frozen Tuna bodies as the guards were escorting us out, I was sad and angry that we are still killing and eating a species that is so close to extinction.

The next day, I went to a sushi restaurant with my aunts, grandparents, uncles, brothers, nieces, parents, and sister-in-law. Several of them selected slender cuts of Bluefin as they scrolled by on the moving conveyor belt. They hid their eyes from me in joking half embarrassment as they downed the delicious morsels. That's when I almost cried.

Experts estimate that sometime in 2012 (2012!!!) the Bluefin Tuna will pass the point of no return on the road to extinction, unless something changes.

If you want to help make the change and stop the extinction, support these guys. They're going to make a direct last ditch direct effort to stop illegal fishing, since much of the Tuna sold on the market is caught illegally. They also made the animation at the start of this post and are working on several other campaigns to raise awareness about our impact on the Bluefin Tuna.

For a broader scale impact, support WWF, who are working from a more political angle to stop the unsustainable fisheries practices.

Also, please, stop eating Bluefin Tuna. I don't want to cry.

It's a Big Problem

Basking Shark (Cetorhinus maximus)
(Photo courtesy www.sharkireland.com)

The Basking Shark is endangered in the Pacific and in trouble in the Atlantic (COSEWIC 2007, listed as vulnerable by the IUCN) and is little known by most humans. A call to our lab to determine which “sea monster” carcass had washed up on a Nova Scotia shore had us discover a Basking Shark that had apparently died at sea.

These gentle giants can grow up to 15 metres in length and have the longest known gestation period of any vertebrate (up to 3.5 years!), so replacement is low. Despite their size, I think Basking Sharks are pretty cute. First, they’re filter feeders, so the fear factor is totally related to being humungous and able to knock your head off with a casual flip of the tail. Second, their rounded noses make them look a bit more like a seal than a shark. Unfortunately, they can become tangled in nets and fishing lines or hit by ships as they cruise near the surface of the water, feeding on the rich biodiversity of plankton there.

I’ve been up close and personal with a lot of Atlantic sharks, and their sheer bulk makes them seem invincible. They aren’t. In the pacific, the situation is even worse.

What can you do to help them out? As with any ocean fish, this is a tough question. Avoiding cruise ships is a good first step, but minimizing your contribution to water pollution (salts, fertilizers, sewage? learn more here) and eating a vegetarian diet (slower global warming and no nets or lines to tangle or maim non-target species) are even better. Finally, tell your friends! We’re the species responsible for their decline, so we can certainly act to change that.

Endangered Eating: The End of Tuna

Atlantic and Southern Bluefin Tuna, (Thunnus thynnus and maccoyii), Critically Endangered

So much has been written about the plight of Bluefin Tuna that I feel it's pointless to add another article to the mix. However, if you aren't aware of what's happening to our Tuna, you should read one or two of the articles below. Our fish are being used up at a ridiculously unsustainable rate. If you can't be bothered to read any of the articles, the main gist is this--stop eating Bluefin Tuna for a while, or in a few years, there won't be any left.

Check out Tuna can stay on the menu... for now, to get an idea of which Tuna species are sustainably harvested if you're a Tuna lover, or become a sustainable seafood consumer.

Latest Statistics

The IUCN (International Union for Conservation of Nature) has recently issued an updated version of its well-known IUCN Redlist, the most comprehensive and authoritative measure of the endangered-ness of species around the world. According to the latest information, 17,291 species are threatened with extinction out of a total of 47,677 assessed species. "The scientific evidence of a serious extinction crisis is mounting,” according to Jane Smart, Director of IUCN’s Biodiversity Conservation Group.

Below are some graphs, illustrating the most recent statistics. Red areas represent species that are threatened. One thing to keep in mind while looking at these charts--these graphics represent only species that are assessed by the IUCN. So, although just about all of the known mammal, amphibian, and bird species have been described and assessed, only small percentages of the world's known plants, invertebrates, fish, and reptiles, have been assessed. Which of course means that there are a lot of species out there whose status is unknown. They may be threatened or not--we just don't know. If you're interested in more details, check out the Summary Statistics published by the IUCN.

Baby Goliaths Can't Hide

Goliath Grouper (Epinephelus itajara), Critically Endangered

The Critically Endangered Goliath Grouper is the largest grouper in the Atlantic, growing more than 2 meters (6 feet) long, weighing more than 450 kg (1000 lbs), and living up to 40 years. Recently, the Ocean Research & Conservation Association (ORCA) used an underwater acoustic camera system (similar to the sonar dolphins or bats use) to visualize baby Goliaths among the murky waters of mangrove roots. Baby Goliaths, up to 1 meter long, spend the first 5-6 years of their lives, almost exclusively in and amongst the waters around mangroves.

Conservation action began in 1990 when the US placed a moratorium on fishing, and the Caribbean did the same in 1993. Though the population has increased it will take many years for numbers to recover to previous levels. Additionally, in some areas, fishing continues despite the bans. It is sometimes difficult to accurately assess the recovery of the species, in part because of the inability to visualize Baby Goliath numbers in murky and cloudy waters. The new camera system used by ORCA should alleviate this problem, and make surveys of Goliath populations easier.

Short Snouts are Back

Short-snouted Seahorse (Hippocampus hippocampus), Data Deficient

Earlier this month, conservationists from the Zoological Society of London announced that several Short-snouted Seahorses (which are actually fish, for those who wondered) had been found in the Thames River. Though they had been found earlier, the announcement was delayed, until official protection for the Seahorses came into effect on April 6, 2008, under the Wildlife and Countryside Act, 1981. Conservationists believe that the rediscovery of the Short-snouted Seahorse illustrates the improving health of the Thames as habitat for marine life.

The conservation status of Short-snouted Seahorses is unknown, and the IUCN classifies them as Data Deficient. They could be abundant and plentiful . . . or they could be teetering on the brink of extinction.

The Seahorse Trust works worldwide to conserve Seahorses, and you can donate to their cause from their website.

Prize Fish

Mekong Giant Catfish (Pangasianodon gigas), Critically Endangered

Here's a great post, over at Endangered Ugly Things, about a crazy big fish.

Wadi fish go?

Garra barreimiae Garra barreimiae

In the Arabian Peninsula, wadis are riverbeds which are dry for most of the year, and full of water for the rainy season. There are, however, some riverbeds and pools that maintain water all year round. And in these, survive several species of fish--wadi fish. When the annual floods begin, these fish swim upstream and lay eggs in the highest pools.

However, they are threatened on many fronts--development, introduction of invasive species, lowering of the water level due to pumping, the building of dams, and pollution. Very little is known about the habits or range of these fish, although studies are underway.

Here's a photo of one better known species, Garra barreimiae, and an
article about wadi fish.

Endangered Eating - Phillipine Dish of the Day

Giant Grouper
Dwarf Pygmy Goby
Whale Shark
Basking Shark
Zebra Shark
Big-eye Tuna
Blue-fin Tuna
Giant Manta Ray
Sea Turtles
Whale
Dolphin

These are just a few of the endangered species that are found on the menus of many restaurants in Manila. Although it is illegal both within the country and internationally to harvest, sell, or trade these species, they continue to persist in restaurants in the Phillipines. With 40 million Phillipinos relying on seafood as a primary part of their diet, and unchecked poaching, barely 1% of the countries reefs remain in pristine condition.

Here's a story about some poachers who may be getting off too easy.

Endangered Eating - Fish and Chips

Spiny Dogfish (Squalus acanthias)
Porbeagle (Lamna nasus)

What do Schillerlocken, Saumonette, Fish and Chips, Zeepaling, and Rock Salmon have in common? All of them are foods made from the meat of the Spiny Dogfish, a species of shark listed as Vulnerable, on the IUCN’s Redlist of Endangered Species.

In Germany, Schillerlocken is a smoked meat delicacy. In France, it is sold as saumonette, which translates to little salmon. In the UK, order some Fish and Chips, and Rock Salmon, another name for the shark, is what you’ll get. Or go to Belgium and dine on zeepaling, aka sea eel. Another way to enjoy this endangered species is as shark fin soup in Chinese cuisine.

Another shark, the Porbeagle (also listed as Vulnerable on the Redlist), is eaten fresh, frozen, dried, and salted throughout Europe. Both species are declining, mainly as a result of overfishing to meet demand.

A proposal is being spearheaded by the German government, to add these two species to Appendix II of the CITES agreement, which would require that international trade in these species be sustainable and non-detrimental to the species or their ecosystems. However, the success of the proposal is questionable, as it requires the support of the rest of the EU member countries.

Help spread the word about the dangers of overfishing sharks through the Shark Alliance, or donate to Oceana, an organization active in preserving many ocean species, including sharks.

Rays of Love

Shark Ray (Rhina ancylostoma), Vulnerable

The Newport Aquarium in Kentucky has acquired a male Shark Ray, hoping that it will mate with Sweet Pea, their female Shark Ray. Curiously, it's not known exactly how the Rays mate, as they have horny ridges on their neck and back, a dorsal fin and rounded undersides. The Shark Ray is listed as Vulnerable on the IUCN's Redlist.

Abundant in the Hudson

Shortnose Sturgeon (Acipenser brevirostrum)

Here's something you don't hear about everyday. The shortnose sturgeon, listed as vulnerable on the IUCN's Redlist, appears to be recovering, at least in certain rivers in North America. Although the article cites a 400% increase in the Hudson River since the 70s, it makes no mention of other rivers where this species is also threatened.

Here's the article.
