2013-09-20 10:02:32

Brett Smith for redOrbit.com - Your Universe Online A newly published study led by researchers at the University of Washington has identified the anatomical differences between the different filters of various marine rays. Study researchers said their findings could be used to assess the species of ray filters being sold in Asian apothecary shops and to create new and improved manufacturing filters. The Washington researchers said they have found enough signature markers to be able to...

Sharks Linked To Coral Health
2013-09-19 09:53:11

Brett Smith for redOrbit.com - Your Universe Online Sharks play an important role in the food web of a marine ecosystem and a study recently published in the journal PLOS ONE has found that overfishing of these predators can have a disruptive effect on coral reefs. "Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous fishes which play a key role in promoting reef health," said study author Jonathan Ruppert, a marine ecologist with the...

Threats Of Overfishing And Extinction Can Be Predicted Decades Before Population Declines
2013-09-18 12:19:10

University of California - Santa Barbara A new UC Santa Barbara study shows that threats created by overfishing can be identified decades before the fish species at risk experience high overly harvest rates and subsequent population declines. Researchers developed an Eventual Threat Index (ETI) that quantifies the biological and socioeconomic conditions that eventually cause some fish species to be harvested at unsustainable rates. The findings are published in the Early Edition of the...

Genetic Basis For Behavior In Fish Found
2013-09-12 19:08:48

Brett Smith for redOrbit.com – Your Universe Online A new study on the schooling habits of fish could provide new insights into the social behaviors and natural variations of humans. Published on Thursday in the journal Current Biology, the new study was able to trace the tendency and the aptitude for schooling to different genomic regions in the threespine stickleback, a small fish that lives in the Northern Hemisphere. "The motivation to be social is common among fish and...

The journal Herpetologica presents a study in which Barton Springs Salamanders were exposed to three different species of fish predators—the Western Mosquitofish, Redbreasted Sunfish, and Largemouth Bass—and a blank water control. The current study used captive-bred salamanders that had never been exposed to the predators before and could not have a learned response. (PRWEB) September 11, 2013 How a species reacts to potential predators plays a role in how conservationists might...

2013-09-06 09:22:06

[ Watch the Video: Migrating Sharks May Be To Blame For Increased Attacks ] Brett Smith for redOrbit.com - Your Universe Online The recent rash of shark attacks in the Hawaiian Islands may be explained by the migratory patterns described in a report recently published by the journal Ecology. Based on a seven-year study of tiger shark movement, marine biologists from the University of Hawaii and University of Florida discovered that about 25 percent of the mature female tiger sharks...

The escolar (Lepidocybium flavobrunneum) is a species of fish found in tropical to temperate waters 650 to 2,900 feet in depth, around the world. It is also known as the snake mackerel, walu and sometime sold as butterfish or white tuna. It has been mislabeled in restaurants and fish markets as white tuna. In studies from 2010 to 2013, it was found that 84 percent of over 114 samples of tuna were actually escolar. However, the studies were conducted with no quality control so the accuracy...
