Fish fear robotic predators......

Unless they're drunk.

Scientists swear they had a really good reason for building a robotic fish, getting some other fish drunk, and then chasing them around with it.

Extraordinary trout have tolerance to filthy water

New research from the University of Exeter and King’s College London has shown how a population of brown trout can survive in the contaminated waters of the River Hayle in Cornwall where metal concentrations are so high they would be lethal to fish from unpolluted sites.

West Is Best: Study Ranks U.S. States for Marine Conservation Progress

Compiling data from MPAtlas.org and MPA.gov; researchers from the Marine Conservation Institute in Seattle, Washington; and Mission Blue calculated the fraction of coastal waters that each state or territory has designated as a no-fishing zone.

Here's the percentage of state waters currently set aside in no-take reserves:

22.9%: Hawaii

8.7%: California

5.7%: U.S. Virgin Islands

1% or less: Florida, Puerto Rico, Oregon, the Commonwealth of the Northern Mariana Islands, Guam, Washington, American Samoa, North Carolina, Virginia, and Maine.

0%: Alabama, Alaska, Connecticut, Delaware, Georgia, Louisiana, Maryland, Massachusetts, Mississippi, New Hampshire , New Jersey, New York, Rhode Island, South Carolina, and Texas.

While science says that marine reserves help fish stocks recover, recreational fishing interests mobilzed in fierce opposition when California's marine protection areas were first proposed.

So how are those California's marine reserves working?

Six years after California put in place the nation's most expansive network of marine reserves -- a controversial experiment aimed at bringing back crashing populations of fish and other ocean species by creating dozens of "no-fishing zones" along the coast -- the effort appears to be working.

Shark Survey

Recreational angling for sharks is becoming a popular leisure activity worldwide. Sharks are also landed as bycatch when recreational anglers target other fish species. Given the important role sharks play in marine ecosystems, developing a better understanding of when recreational anglers encounter sharks and how they handle sharks once landed is important for their conservation and management.

Please consider taking this short survey that begins to compile angler-based information regarding sharks.

Thanks!

The fact that the fish can quadruple the size of its digestive tract makes for a distinct advantage

Researchers have discovered that Dolly Varden feasts once a year and, in doing so, quadruple the size of its stomach.

Other animals have been discovered to grow and shrink their digestive tracks, but this is the first time researchers have found a wild fish to do so.
