Shark populations around the world are crashing. Researchers have reported that many populations have decreased by 90% or more since the 1970’s. The leading causes for these precipitous declines are bycatch, which kills tens of millions of sharks each year, and the shark fin fishery, which kills as many as 73 million sharks each year. … Read More “State of the Field: Shark Conservation Policies” »
From the Guardian: Japan has temporarily suspended its annual whale hunt in the Antarctic after anti-whaling activists obstructed its fleet’s mother ship. Officials in Tokyo have conceded that this year’s mission, which had again been the target of international criticism, had not gone as well as hoped and the fleet may be called home early, … Read More “Japan temporarily suspends Antarctic whale hunt” »
The droughts that shook the east African nations in the mid-1970’s and again in the 1980’s decimated the traditional nomadic clans of Somalia, leaving them without live stock to feed their families. Tens of thousands of the dispossessed, primarily of the Hawiye clan, were relocated to coastal areas. Fishing communities took root and began to flourish. … Read More “Nothing to plunder – the evolution of Somalia’s pirate nation” »
Although marine fish face many threats, one of the greatest is large-scale modern commercial fishing. Technology makes it all too easy for so-called “factory ships” to remove enormous numbers of fish from the oceans, sometimes with devastating effects on the populations of those fish and their habitat. Marine conservationists have proposed a variety of policies … Read More “Can marine protected areas save the oceans? Under certain circumstances, maybe.” »
Conservation efforts often have an associated tradeoff, and many proposed solutions are shot down because the costs are perceived to be too high. A conservation policy that benefited a charismatic endangered species with very little cost should be popular and enthusiastically adopted. However, even though turtle excluder devices greatly reduce sea turtle mortality and have … Read More “Turtle excluder devices: analysis of resistance to a successful conservation policy” »
Yesterday afternoon, the Presidents of Honduras and Palau challenged other world leaders to follow their example by protecting sharks. Both nations have banned shark fishing within their territorial waters, and they are encouraging other nations (both rich countries with fishing fleets and poor coastal countries) to do the same. This announcement was timed to coincide … Read More “A global shark conservation challenge from Palau and Micronesia” »
Last weekend, longtime SFS reader Suzy sent me an interesting question. Suzy is Asian, and though she is a committed conservationist, several members of her family regularly eat shark fin soup. One relative just sent her a copy of a news article entitled “Shark Fin Soup: Eat it without guilt” (available here). Suzy asked me … Read More “Reader mail: Shark Fin propaganda” »
The structure of the science blogosphere is changing. That much is apparent to anyone who follows any of the many talented writers who sail under the flag of ScienceBlogs. Several of the most popular writers have left, gone on strike, or are in the process of deciding their fate. I don’t need to rehash any … Read More “The shifting winds of science blogging” »
Last February we introduced Bomai Cruz as the second blog in the Southern Fried Science Network and the first to operate under the blog.southernfriedscience.com format. Our plans to expand the network lay dormant after that first launch, for many reasons, not the least of which was that I had just moved Southern Fried Science to … Read More “Changes afoot” »
We sparked a good debate over the effectiveness of direct action conservation movements over at the post “Is Sea Shepherd really saving whales?” One of the most difficult questions raised was if Sea Shepherd wasn’t there, would the Japanese make their full quota? The data presented in that post was inconclusive, because the quota increase … Read More “Whale Quotas and Sea Shepherd” »
