Shark fin bans: A storify of this week’s twitter discussion

May 8, 2012 David Shiffman 20 Comments

Conservation, Science

Earlier this week, I asked my twitter followers what they thought about shark fin bans, which prompted a long and stimulating discussion. What follows is my first attempt at “Storify”, shared in the hopes that the discussion can continue here.

As I’ve said before, I’m not a big supporter of shark fin bans because they don’t allow for sustainable, well-managed fisheries to supply the market. Additionally, they promote the common (and false) belief that shark fin soup is the only major problem facing sharks, and don’t address many of the other important issues associated with shark conservation.

Instead, I favor a comprehensive approach to shark management, including requiring that sharks be landed with fins attached (i.e. a ban on “finning” but the fins can still be used if the shark is landed whole), special protections for threatened and endangered species, science-based fisheries quotas for species that can sustain fishing, time/area closures or gear restrictions when necessary, and careful monitoring (including requiring that all fishing nations report the species composition of their catch).

Check out the great discussion if you missed it, and let me know what you think of this important issue in the comments of this post.

Recollections from a future ocean – a short story for eno magazine

eno. is the new literary magazine for the Nicholas School of the Environment at Duke University. Its mission is “to inspire a respect for our environment by engaging in thoughtful expression through the use of artistic, reflective, and creative forms.” This year, I have two poems and one short story featured. Both poems can be found … Read More “Recollections from a future ocean – a short story for eno magazine” »

#TaxonomyFail: Salps, Jellyfish, and the Diablo Canyon Nuclear Power Plant

May 1, 2012November 4, 2013 Andrew Thaler 26 Comments

Science

I’m a bit late to the party, but last week, several news outlets reported that the Diablo Canyon Nuclear Power Plant was taken offline by “jellyfish-like creatures” that clogged several cooling intakes. While most sources were careful to point out that these were “jellyfish-like” organisms, some secondary sources truncated the description and announced that “Nuclear Power Plant Knocked Offline By Tiny Jellyfish, The Invasion Has Begun”. Unfortunately, these organisms are salps, not jellyfish, and you’d be more correct to describe them as human-like rather than jellyfish-like.

Salps are free-swimming pelagic tunicates, one of the most basal members of the chordate phylum. While they superficially resemble jellies to the untrained eye, they are far more derived, possessing three tissue layers (compared to the jelly’s two), a primitive, larval notochord, a perforated pharynx, and the rudimentary beginnings of a centralized nervous system. They form large, clonal colonies that are able to take advantage of plankton blooms by rapidly producing more clones to capitalize on an unpredicatable food source. Although I don’t have first hand reports, this is likely what happened in Diablo Canyon, as warm water discharges from nuclear power plants can trigger massive plankton blooms. Far from a “jellyfish invasion”, this was probably the natural response of a predator to increased food availability.

Swordfish, certifications, and sustainable seafood

May 1, 2012October 27, 2013 Guest Writer 4 Comments

Jordan Nikoloyuk is the Sustainable Fisheries Coordinator of the Ecology Action Centre, a membership-based community environmental organization based in Nova Scotia, Canada. The Marine Issues Committee of the EAC was founded in 1995 after the collapse of the Atlantic Canadian groundfish stocks and works towards conserving and protecting marine ecosystems and maintaining sustainable fisheries and vibrant coastal communities.

As part of its sustainable seafood work and through its Friends of Hector campaign – www.friendsofhector.org – the EAC has participated in many Marine Stewardship Council assessments for Atlantic Canadian fisheries and encouraged retailers to support certified fisheries. Jordan has written this guest post to share his recent experiences with a certification that has left the EAC and other conservation organizations wondering whether seafood certification can contribute to sustainable fisheries management in the long term, or if the conflict between keeping an eco-label rigorous on the one hand and expanding its market appeal on the other is just too difficult to manage. What do you think?

The best way to buy seafood responsibly is to read a sustainable seafood guide and ask your retailer the two big questions: where is this from and how was it caught? When getting these answers is tough, many people turn to eco-certifications and labelling. Despite some increasingly controversial certifications, the Marine Stewardship Council (MSC) is considered to be the most trusted and reliable label, but how many unsustainable fishery certifications will it take to ruin this credibility?

Last week, after lengthy and widespread opposition, the MSC approved certification of the Atlantic Canadian longline swordfish fishery, which catches 100,000 sharks and 1,400 endangered sea turtles every year. The Ecology Action Centre spent almost two years working to oppose this greenwashing. Now we are left asking: how can we promote sustainable fisheries with organizations the size of the MSC working against us? When a definition of sustainability is so weak that it lets the status quo continue, can this be seen as an effective ‘market-driven solution’?

The Ocean Question: What is your favorite marine organism and why?

We caught up with 11 marine scientists (including one honorary marine scientist, paleoblogger Brian Switek) at this year’s Ocean Sciences meeting in Salt Lake City and asked them the following question – What is your favorite marine organism and why? Their responses ranged from the classic (dolphins and sharks) to the bizarre (deep-sea shrimp and snails) to the exceptionally … Read More “The Ocean Question: What is your favorite marine organism and why?” »
