Fish accustomed to living near the light of the water's surface become proverbial "fish out of water" when they move to dark environments like those found in caves, according to a study from North Carolina State University. http://phys.org/news224305171.html Biology Wed, 11 May 2011 03:59:55 EST news224305171 New research from Columbia University Medical Center continues to shed light on the benefits of making fish a staple of any diet. http://phys.org/news153073435.html Medicine & Health Thu, 05 Feb 2009 16:24:37 EST news153073435 Urgent action is needed to limit damages to marine ecosystems, including coral reefs and fisheries, due to increasing ocean acidity, according to 155 of the world’s scientific experts who will release the Monaco Declaration this Friday. http://phys.org/news152527254.html Space & Earth Fri, 30 Jan 2009 08:41:24 EST news152527254 A pair of studies, led by Medical College of Wisconsin scientists at Children's Research Institute in Milwaukee, may translate into rapid molecular tests to distinguish between hemangiomas and congenital blood or lymph vessel malformations in infants. Hemangiomas are common birthmarks consisting of benign tumors of blood vessels.

Nowhere is this more apparent than in worldwide fisheries, where thanks to overfishing and habitat destruction, countless species and populations of fish are on the brink of disappearing forever. To attempt to mitigate the dire situation, captive breeding, the controlled breeding of organisms in protected environments, is regularly initiated. http://phys.org/news148218342.html Biology Thu, 11 Dec 2008 11:45:42 EST news148218342 (PhysOrg.com) -- Striped bass in the San Francisco Estuary are contaminated before birth with a toxic mix of pesticides, industrial chemicals and flame retardants that their mothers acquire from estuary waters and food sources and pass on to their eggs, say UC Davis researchers. http://phys.org/news148049152.html Space & Earth Tue, 09 Dec 2008 12:45:52 EST news148049152 Scientists have discovered that management efforts intended to assist migrations of salmon and steelhead trout can have unintended consequences for fish populations. Juveniles that are transported downstream on boats can lose the ability to migrate back to their breeding grounds, reducing their survivorship and altering adaptations in the wild. http://phys.org/news147696956.html Space & Earth Fri, 05 Dec 2008 10:55:56 EST news147696956 Mercury levels in fish are prompting widespread consumption advisories and uncertainty among consumers over which species are safe to eat.

A report scheduled to be published this week in the early edition of the journal Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring coral reefs, which are declining dramatically worldwide. The conclusion results from a long-term study that found significant recovery in sections of coral reefs on which fish of two complementary species were caged. http://phys.org/news142690736.html Biology Wed, 08 Oct 2008 13:18:56 EST news142690736 When reef fish get a mouthful of sand, coral reefs can drown. That's the latest startling evidence to emerge from research into the likely fate of reefs under climate change and rising sea levels, at the ARC Centre of Excellence for Coral Reef Studies (CoECRS). http://phys.org/news142675594.html Biology Wed, 08 Oct 2008 09:06:34 EST news142675594 (PhysOrg.com) -- Ever since Darwin discovered that species can evolve, scientists have wondered how new species form. Answering this question is the key to understanding the diversity of all of life. A group of colorful fishes in Africa's Lake Victoria have been the focus of scientific efforts to unravel how new species form. This lake contains more than 500 species of cichlids, which play a leading role because of their rapid speciation and remarkable diversity. Still, the mechanisms involved in the rapid appearance of new cichlid species have remained elusive to scientists. http://phys.org/news142615133.html Biology Tue, 07 Oct 2008 16:18:53 EST news142615133 The roadmap to the future of the gorgeously-decorated fish which throng Australia's coral reefs and help earn the nation $5 billion a year from tourism may well be written in their genes. http://phys.org/news141994529.html Biology Tue, 30 Sep 2008 11:55:29 EST news141994529 The Captain can’t freeze smelly fish that’s past its best – and Icelandic scientists can now help him out by detecting the levels of stench-making bacteria faster than ever before. http://phys.org/news141887640.html Chemistry Mon, 29 Sep 2008 06:14:00 EST news141887640 An international research team studying sound production in deep-sea fishes has found that cusk-eels use several sets of muscles to produce sound that plays a prominent role in male mating calls. http://phys.org/news141496037.html Biology Wed, 24 Sep 2008 17:27:17 EST news141496037
