The bluefin tuna population in the Pacific Ocean has dropped so low that a coalition of conservation groups have petitioned the National Marine Fisheries Service to protect the species under the Endangered Species Act.
According to the petition, the population has declined more than 97 percent since fishing began, largely because countries have failed to reduce fishing enough to protect the iconic species, a luxury item on sushi menus.
“Without help, we may see the last Pacific bluefin tuna sold off and lost to extinction,” said Catherine Kilduff of the Center for Biological Diversity. “New tagging research has shed light on the mysteries of where majestic bluefin tuna reproduce and migrate, so we can help save this important species. Protecting this incredible fish under the Endangered Species Act is the last hope, because fisheries management has failed to keep them off the path toward extinction.” Continue reading “Endangered species status sought for bluefin tuna”→
Activists say public was short-changed on comment period
Wildlife advocates are going to court to challenge a proposed grizzly hunting plan in Wyoming. A lawsuit filed last week alleges that he Wyoming Game and Fish Commission illegally fast-tracked approval of the plan without allowing adequate public comment.
The approval would authorize the state’s first trophy hunt of grizzly bears in 40 years, but the public only had 30 days to review and comment on the plan — far too short to be able to evaluate the biological consequences of the proposed hunt. The commission simultaneously adopted a tri-state memorandum of agreement with Idaho and Montana to formalize quotas for grizzly hunts, allocating over 50 percent of the quota to Wyoming.

Non-native predators could threaten endangered species in Colorado River
Colorado wildlife managers will try to curb expansion of non-native northern pike in Summit County’s Green Mountain Reservoir by paying anglers a $20 bounty for each fish they deliver to the Heeney Marina.
The illegally introduced fish are taking a toll on trout in the reservoir north of Silverthorne and could escape to the Blue River and make their way to the Colorado River. That could add to the challenges of trying to recover four endangered native Colorado River fish species, according to Colorado Parks and Wildlife.
And for now, there is no smoking gun pointing to a single reason for the decline. That means there’s no easy answer, either, the scientists said, explaining that, across the U.S. there are multiple and geographically diverse factors that play role.
New study shows how to help recover endangered loggerheads
Nobody likes a dirty bedroom and sea turtles are no exception.
New research by scientists at the University of Florida shows that removing beach debris helps sea turtle nesting. At cleared beaches, the number of nests rose by as much as 200 percent, the study shows, while leaving the detritus decreased the number by nearly 50 percent.
With many sea turtle species classified as endangered or threatened, restoring nesting habitat is critical to keeping them alive, said Ikuko Fujisaki, the study’s lead author and an assistant research professor of wildlife ecology and conservation with the UF Institute of Food and Agricultural Sciences.
