Might as well eat ’em: A semi-serious April Fool’s Day ethical debate

Bluefin tuna are some of the most endangered fish in the sea. Prized by the sushi industry for their delicious flavor, populations of bluefin have declined precipitously in recent decades.

They also may be the first species of fish to be driven to extinction by commercial fishing. Normally, when populations of fish get low, it isn’t profitable to fish for them anymore- thus they are not driven to extinction. However, a single bluefin tuna can sell for hundreds of thousands of dollars, so it is still profitable to fish for the last one.

Has President Obama broken a promise on offshore drilling?

I received an e-mail from Oceana today encouraging me to “tell President Obama to keep his promise”. The e-mail claims that while running for President, he campaigned against offshore oil drilling, which would make his recent announcement about allowing offshore drilling a broken promise indeed. However, I seem to remember that Obama as a candidate was for offshore drilling. I went to my favorite non-partisan fact check website, Politifact, to sort this out.

Crowdsourcing ConGen – Populations in Hardy-Weinberg Equilibrium

This post is part of the Crowdsourcing ConGen project. Crowdsourcing is the process of opening up a resource to a community for input and contributions. Throughout the coming year I’ll be posting manageable pieces of this document for the audience of Southern Fried Science to read and review. Please visit the main post for an overview.

“I have never done anything useful. No discovery of mine has made, or is likely to make, directly or indirectly, for good or ill, the least difference to the amenity of the world.” ~ Godfrey Harold Hardy

The simplest model for a population is one in which the frequencies of alleles and genotypes remains constant from generation to generation. Under this model, there are no outside forces influencing selection, there is no tendency for any allele or genotype to be favored over any other, diploid alleles will recombine randomly in accordance with Mendelian inheritance. A population that behaves this way is said to be in Hardy-Weinberg Equilibrium. This almost never happens.

Supply Side Conservation Redux

The following was posted at the old website on January 5, 2010. It is reposted here as a response to the question “Why would you encourage people to consume any kind of seafood when bycatch is always an issue? Would it not be better simply to avoid any seafood whatsoever when we can live perfectly healthy lives without?” raised in Reader Mail: Aquariums, seafood, and my shark documentary. Old comments have be stripped but can be found at the original post here.

The Guilty Planet blog has a novel proposal for the New Year: Boycott Seafood. No, not just unsustainable seafood, not just environmentally destructive seafood, ALL seafood.

Masquerades in Conservation

Is it possible to mistakenly support a cause you disagree with? Well, theoretically no, but it’s really all in the name. There are a number of groups out there with clever titles, but are they misleading? I’ll leave the obvious ones like the Discovery Institute and American Enterprise Association for Public Policy Research to your Google prowess, but here’s a great example from my personal experience: the Coastal Conservation Association.

What might at first appear to be a group supporting conservation biology and ringing the bell for endangered species and receding wetlands is really a group designed to advocate for recreational fishing at all three levels of our government: local, state, and national. Their national website is fairly straightforward about this mission, but it is not so obvious when they’re testifying at a state fisheries meeting.

Four things everyone needs to know about sharks: A shark conservation documentary and lesson plan

March 20, 2010April 4, 2010 David Shiffman 29 Comments

Conservation, Science

One week after the world premier at the Benthic Ecology conference’s Beneath the Waves Film Festival, I am pleased to announce that my new shark conservation mini-documentary, “four things everyone needs to know about sharks”, is now available on YouTube.

Check it out here:

If you are an educator, the movie is intended to be part of a lesson plan about shark conservation. I have created a middle school version, a high school version, and a college version. Contact me at WhySharksMatter AT gmail DOT com with the subject “Shark Lesson Plan” and I’ll send you what I have, or we can discuss making a custom lesson plan that suits the specific needs of your class.

If you are not an educator but care about sharks, the movie can be a stand-alone way to educate your friends, family, coworkers, classmates, etc.

Please let me know what you think about the video by commenting on this blog post.

Thanks to all of my photographer and musician partners in this project!

The latest news out of CITES isn’t encouraging. Marie Levine, President of the Shark Research Institute, is attending and made the following statement: “Animals did not fare well at CITES today.

Bluefin tuna fails to make UN’s list of protected fish

Conservation

Seriously, what the fuck? A proposal to protect the Atlantic bluefin tuna prized in sushi was rejected at a UN wildlife meeting today. The decision was reached after Japan, Canada and scores of poor nations opposed the measure on the grounds that banning exports of the fish would devastate fishing economies. Monaco introduced the proposal … Read More “Bluefin tuna fails to make UN’s list of protected fish” »
