overfishing – Southern Fried Science

Barndoor skates, once a textbook example of overfishing, have recovered enough to allow fishing

Barndoor skates were once thought to be so overfished that a highly-publicized paper from 1998 noted that they had been “driven to near extinction without anyone noticing.” One of the largest skates, barndoor skates can reach over 5 feet in wingspan, which is large enough that their diet includes small sharks like spiny dogfish; for a skate, that’s about as close as it gets to charismatic megafauna!

Recently, NOAA Fisheries announced that Barndoor skate populations off the Northeastern United States had finally recovered enough that fishing for them could resume. This move comes after a 2009 NOAA Fisheries report showed that the species had begun to recover enough that they could be removed from the species of concern list, though they remained protected at the time. “This is good news,” Mike Ruccio, a Supervisory Fishery Policy Analyst for NOAA Fisheries Greater Atlantic Regional Fisheries Office, told me. “Rebuilding overfished stocks is one of the cornerstones of the US domestic policy on fisheries.”

Make for the Planet with Conservation X Labs and the Earth Optimism Summit!

April 11, 2017 Andrew Thaler 2 Comments

Conservation

Invasive species, overfishing, ocean plastics, wildlife tracking, and measuring ecosystem services, are some of the most daunting challenges in conservation.While these challenges require a combination of social, commercial, and regulatory cooperation to address, they can also be tackled through technological innovation, which can bypass some of the largest hurdles to implementing practical, timely solutions.

On April 21, 2017, 18 teams of conservationists, technologists, makers, and hardware hackers will gather in Washington DC and tackle five conservation challenges selected by a panel of experts at the Make for the Planet, part of the Smithsonian’s Earth Optimism Summit. Over three days, teams will work to develop prototypes, strategic frameworks, and model systems that address specific issues within the broader challenge prompt of terrestrial species invasion, overfishing, ocean plastics, wildlife tracking, and ecosystem services.

Ocean Conservation Priorities for 2041

On January 1, 2016, the Southern Fried Science central server began uploading blog posts apparently circa 2041. Due to a related corruption of the contemporary database, we are, at this time, unable to remove these Field Notes from the Future or prevent the uploading of additional posts. Please enjoy this glimpse into the ocean future while we attempt to rectify the situation.

Another year, another set of ocean conservation priorities. As with the last 5 years, there will be some new ones, and some repeats. The biggest issues shouldn’t be a surprise to anyone, plastics have been an issue forever and global norming is rapidly taking over the broader ocean conversation. For a refresher, check out our priorities for 2036, 2037, 2038, 2039, and 2040.

Sea Level Rise Induced Habitat Loss: This has been a big one on the docket the last few years. As the ocean rises many species are experiencing dramatic loss of habitat, especially sensitive coastal nursery grounds. Although we’ve known about this for a while, we haven’t even begun to quantify the extent of damage to marine populations. Salt inundation is also compromising coast terrestrial habitats, driving essential species further inland.

Media coverage of the Yates Supreme Court case isn’t treating illegal fishing seriously

November 6, 2014 David Shiffman 1 Comment

Conservation, Science

This week, the Supreme Court heard oral arguments for Yates vs. the United States. Commercial fishermen John Yates was caught with dozens of illegally caught grouper, he destroyed much of the evidence of this crime, and he was charged under a law designed to prosecute people for destruction of evidence. He is now suing the government for overreach.

The question of whether a law most commonly known for being used to deal with destruction of financial records can also be used to deal with destruction of evidence of illegal fishing is an interesting one. The Obama administration claims that the law was designed to be a generic Federal destruction of evidence ban, and it has also been used, according to a USA Today article, to “go after the destruction of cars, cash, cocaine, child pornography- even murder weapons and bodies.” It seems to me that it is an appropriate role of government to write regulations to ensure that our shared natural resources are sustainably exploited, it is an appropriate role of government to enforce violations of those laws, and it is an appropriate role of government to punish people for destroying evidence of those violations. A much bigger problem, however, is with much of the media coverage of this case.

The Society for Conservation Biology’s International Congress for Conservation Biology took place from July 21-25th in Baltimore, MD. Over 1,500 scientists and conservationists from more than 60 countries participated. Below are selected tweets from marine conservation (and related) sessions. Talks are in no particular chronological order.
