Going diving in the tropics? Don't eat the reef fish!

Thu, 21 Sep 2017 09:02:48 EDT ~ Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new study that suggests other small island nations might also consider adopting this strategy. Find out more...

Efforts to save sea turtles are a 'global conservation success story'

Wed, 20 Sep 2017 18:21:23 EDT ~ A new study of the world's seven sea turtle species provides evidence that their numbers are growing overall (unlike many endangered vertebrates), thanks to years of conservation efforts that have played a key role in sea turtle recovery -- even for small sea turtle populations.

Protected waters foster resurgence of West Coast rockfish

Wed, 20 Sep 2017 15:49:55 EDT ~ West Coast rockfish species in deep collapse only 20 years ago have multiplied rapidly in large marine protected areas off Southern California, likely seeding surrounding waters with enough offspring to offer promise of renewed fishing, a new study has found.

10,000 year-old DNA proves when fish colonialized our lakes

Wed, 20 Sep 2017 10:45:44 EDT ~ DNA in lake sediment forms a natural archive displaying when various fish species colonized lakes after the glacial period. Scientists' analyses of the prevalence of whitefish DNA in sediment reveal that the whitefish came to Lake Stora Lgdasjn in Vsterbotten already 10,000 years ago, whereas Lake Hotagen in Jmtland had its whitefish only 2,200 years ago.

Catching a diversity of fish species instead of specializing means more stable income for fishers

Mon, 18 Sep 2017 23:23:49 EDT ~ A team of scientists analyzed nearly 30 years of revenue and permitting records for individuals fishing in Alaskan waters and tracked how their fishing choices, in terms of permits purchased and species caught, influenced their year-to-year income volatility. Find out more...

When it comes to the threat of extinction, size matters

Mon, 18 Sep 2017 13:27:32 EDT ~ Animals in the Goldilocks zone -- neither too big, nor too small, but just the right size -- face a lower risk of extinction than do those on both ends of the scale, according to an extensive global analysis. Find out more...

Old fish few and far between under fishing pressure

Thu, 14 Sep 2017 15:23:43 EDT ~ A new study has found that, for dozens of fish populations around the globe, old fish are greatly depleted -- mainly because of fishing pressure. Old fish are increasingly missing in many populations around the world. Find out more...

Fish food for marine farms harbor antibiotic resistance genes

Wed, 13 Sep 2017 19:31:26 EDT ~ From isolated caves to ancient permafrost, antibiotic-resistant bacteria and genes for resistance have been showing up in unexpected places. As scientists puzzle over how genes for antibiotic resistance arise in various environments and what risks to human health they might pose, one team has identified a surprising way some of these genes are getting into ocean sediments: through food for marine fisheries.

Climate change challenges the survival of fish across the world

Wed, 13 Sep 2017 19:29:38 EDT ~ Researchers have published the first analysis looking at how vulnerable the world's freshwater and marine fishes are to climate change. Their study used physiological data to predict how nearly 3,000 fish species living in oceans and rivers will respond to warming water temperatures in different regions. Find out more...

Farming fish: Marine biologists identify movement patterns of a parrotfish species that rotationally harvests its favorite algae, defends its feeding territory

Tue, 12 Sep 2017 15:48:52 EDT ~ Steephead parrotfish (Chlorurus microrhinos) are picky eaters. In the central Pacific, however, they appear to have taken matters into their own hands -- er, fins. Find out more...
