Antidepressants make for sad fish

The drugs are becoming more common in river waters and can play dangerous head games with fish. 
Damming doesn't hurt salmon? Something is fishy, scientists say.

Damming rivers is an environmental conundrum. On the one hand, hydroelectric power provides clean, relatively reliable energy. On the other, damming rivers can endanger fish populations ...or can it? A recent study performed on the dammed Columbia River and undammed Fraser River suggests that perhaps the smolts are all right.
Salmon travel the rivers at two points in their lives: first, they must find their way downriver to the ocean as smolts (juveniles) and second, they must find their way back upstream to the spawning grounds in the last stage of their lives
Red Fish, Blue Fish, One Fish Becomes Two Fish

Changes in vision lead to new species in cichlids in a form of sexual selection not usually seen (or at least not usually recognized).
Mutualism alters fish behavior
Darkfrog submitted, created time 2 months 1 day (www.nature.com)
A type of fish called the cleaner wrasse seems to haev a calming effect on local predators. The wrasse eat parasites off the scales of larger fish and even provide what Nature writers have called "a calming massage" with their fins. In return, the client fish keep returning to the wrasses' territory to provide them with more food.
However, what researchers have recently noticed is that client fish stop hunting each other while in wrasse territory--even while they are waiting to be served.
Eating fatty fish lowers risk of dementia

Eating tuna and other fatty fish may help prevent memory loss in addition to reducing the risk of stroke, Finnish researchers said on Monday.
Lawsuit puts sea bass experiments on hold
Darkfrog submitted, created time 3 months 3 weeks (www.nature.com)
Any Dr. Evil fans out there? FIsh farmers' attempts to train sea-bass (no note is given as to whether they are ill-tempered) have been halted by a lawsuit.
The Food and Water Watch has had a temporary injunction issued, claiming that there has not been enough investigation as to whether the food cage to be used in the experiment will not pollute surrounding waters. Fine with me. Investigation is good. We should all know the risks, because there are GOING to be risks.
Overly furry secret agents were in no danger, though
Warming Spells Trouble for Fish

Model predicts extinctions for polar fish and other species unable to migrate.

Although young flatfish have one eye on each side of their heads, the adult flatfish sports both on one side. This allows the fish to lie on the sea floor looking up and still retain its depth perception. This ocular migration has puzzled gradual evolutionists. If the trait evolved gradually over many generations, then why aren't there fossils showing fish with partially migrated eyes?
Well today's Nature posts the discovery of two such fish fossils, blowing a giant raspberry at both creationists and sudden-jump evolutionists alike.
Deep trouble--fish seeking colder waters may have nowhere to go
sea-maid submitted, created time 4 months 3 weeks (www.nature.com)
An increasing number of species are migrating in response to global warming; some alpine organisms are climbing to higher altitudes. Other animals are moving towards the poles.
A new study suggests that as sea temperatures rise, many fish may be electing to move into deeper, cooler waters, rather than moving to higher latitudes as many theorists had previously predicted. This presents a problem: the deeper the fish go, the less light and food they find.

Girls who eat more omega-3 fatty acids outsmart those who eat higher amounts of omega-6 fatty acids, according to new research. As a result of this and other studies, government dietary recommendations--especially those aimed at pregnant women--should emphasize fish over soy and corn oils, which are respectively high in these fatty acids.
Women who accumulated more fat on their hips than on their waists--and who, therefore, had low waist-hip ratios like many movie stars--had higher cognitive test scores, as did their children
Diving lessons from the world's biggest fish

The world’s biggest fish--the whale shark--doesn’t have a reputation for speed. But researchers have discovered that although the fish seem sluggish on the surface, deep down they are deceptively fast.
Fishing for Oxygen in Warming Oceans

The oxygen concentrations in some oxygen-minimum zones have decreased with time and few fish and other sea life can survive in such waters. What's more, this state will deteriorate.
Pesticide Brew Spells Trouble for Salmon
Sue Wu submitted, created time 9 months 1 week (sciencenow.sciencemag.org)
Salmon in the U.S. Pacific Northwest, and elsewhere, have been in a world of hurt for decades. One of their main enemies is agricultural chemicals, such as chlorpyrifos. The pesticide interferes with salmon brains and harms their ability to feed, according to studies by zoologist Nathaniel Scholz of the National Oceanic and Atmospheric Administration in Seattle, Washington. Now Scholz's research is showing that mixtures of pesticides are even worse for salmon and can be surprisingly lethal.
Voyeurs put male fish off their ideal mate
snoopy submitted, created time 11 months 3 weeks (technology.newscientist.com)
An interesting research was carried out by some researchers these days. That says mating fish don't like an audience. If there’s another male spying on them, they change their mind about which female they prefer.
Researcher Plath thinks that fishes act like this to avoid sperm competition. Another possible explanation would be that the desire to fight a competitor distracts the very fishes from their true mate preference, although Plath considers this less likely
Antioxidants can change fish behaviour
jane2007 submitted, created time 1 year 3 weeks (www.nature.com)
Antioxidants are all the rage, with research suggesting that they may help to prevent cancer, strokes and heart disease. Now a study highlights how these oxygen-mopping compounds affect more than just cellular health: they also seem to effect behaviour.
