Loggerheads in PLoS Today: The BIG Impact of Small-Scale Fisheries


Never underestimate the impact of the little guys... at least when it comes to fishing practices and North Pacific loggerhead sea turtles. Today in PLoS one, Ocean Conservancy Scientist Wallace J. Nichols and University of California (UC)-Santa Cruz researcher Hoyt Peckham report that small-scale operations are a greater threat to the survival of loggerheads than large industrial practices. This finding comes after 10 years of research and what makes it interesting is the result is not quite what we'd expect...

The New York Times recently explained:

"For an oceanic species such as the loggerhead, these are incredibly dangerous times. It is partly the longevity of these creatures that makes their death as bystanders among the global fishing fleets feel so tragic, a truly colossal waste of life."

Same place and same turtles! Loggerheads hang out here for up to three decades before returning to Japan to breed. (Meaning if I were a loggerhead, I'd probably still be in Mexico.) In the past 10 years, the number of nesting females in Japan has declined by 50 to 80 percent.

i-78df92a4f2bcb832de98c29c11dd9fba-dead loggerhead.JPGNichols and Peckham explain that small-scale fishing operations inadvertently kill turtles as bycatch along with other non-target species like seabirds, dolphins, and sharks. But it's not all doom and gloom. The team is actively engaged in local efforts to educate fishermen about protecting this endangered species. And plenty more is being done by the good folks with The Ocean Conservancy and beyond who are working at the local level to understand both the species and communities involved.

Or better yet (you lucky readers), join in on a loggerhead sea turtle expedition HERE!

Real pleased to see a name like Nichols submitted to PloS one. I love the idea of free and open access to research and this encourages me to publish there too.

Sheril and Chris, thanks for pointing this out. Cool article too.

Adam beat me, but I couldn't agree more on all counts. Great research, science, journal, and coverage here. Thanks Intersection.

Hope both the education and the progress continues at a rapid pace for all.

PLoS actually makes me care about publish my data ;>

ok, I would anyway, but all journals should be open access
