No other modern animal may command both our fears and fascination as much as the great white shark – but The Maritime Aquarium’s new IMAX film suggests, instead, that these incredible predators mainly need our help and respect. “Great White Shark” unravels the mystery of the creature we love to fear in telling the true story of its role atop the oceanic food chain. Norwalk, CT (PRWEB) November 11, 2013 We're not going to need a bigger screen. The six-story screen of The...

Researchers Tease Out Cues That Impact Schooling Fish Behavior
2013-10-31 11:12:23

NYU-Poly Recent studies from two research teams at the Polytechnic Institute of New York University (NYU-Poly) demonstrate how underwater robots can be used to understand and influence the complex swimming behaviors of schooling fish. The teams, led by Maurizio Porfiri, associate professor of mechanical and aerospace engineering at NYU-Poly, published two separate papers in the journal PLOS ONE. These studies are the latest in a significant body of research by Porfiri and collaborators...

In Order For Fish And Rice To Thrive In Yolo Bypass, Just Add Water
2013-10-24 13:30:31

University of California - Davis From a fish-eye view, rice fields in California's Yolo Bypass provide an all-you-can-eat bug buffet for juvenile salmon seeking nourishment on their journey to the sea. That's according to a new report detailing the scientific findings of an experiment that planted fish in harvested rice fields earlier this year, resulting in the fattest, fastest-growing salmon on record in the state's rivers. The report, provided to the U.S. Bureau of Reclamation,...

New Air Breathing Amazonian Fish
2013-10-15 13:06:06

Lee Rannals for redOrbit.com - Your Universe Online A new, air-breathing Amazonian fish reported in the journal Copeia marks the first time a new species of arapaima has been identified since 1847. Dr. Donald Stewart of the SUNY College of Environmental Science and Forestry discovered the species dubbed Arapaima leptosoma while attempting to reclassify arapaimas, which is among the world's largest freshwater fish. Arapaimas can grow up to 10-feet in length and weigh 440 pounds. The...

Mosquitofish Mating Strategies Change In The Presence Of Predators
2013-10-11 12:44:08

North Carolina State University When predators lurk nearby, male Bahamas mosquitofish (Gambusia hubbsi) change mating strategies, rejecting elaborate courting rituals for more frequent and sometimes forceful encounters with females. But as a recent North Carolina State University study shows, mating strategies aren’t the only things changing for G. hubbsi when predators abound. The shape and size of the male fish’s genitalia are also linked to the presence or absence of predators....

New Electric Fish
2013-09-25 12:54:23

Lee Rannals for redOrbit.com - Your Universe Online A new species of electric fish has been discovered in the murky waters of the upper Mazaruni River in South America. Scientists reported in the journal Zoological Scripta that they discovered a species that they've dubbed Akawaio penak in the remote regions in northern Guyana during an expedition. The team analyzed tissue samples collected during the trip, and found that the fish represents not only a new species but also a new genus....

Researchers Identify Ray Species Used For Their Filters In Asian Medical Trade
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...

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...

Ichthyology is the study of fish that focuses on many types of fish including cartilaginous fish, jawless fish, and skeletal fish. This branch of zoology can be associated with marine biology and fisheries science, as well as other areas of study. Ichthyologists, those who practice ichthyology, have discovered more than 32,200 species of fish, and it is thought that they discover 250 new species each year. Humans first began to study fish during the Upper Paleolithic Revolution, when humans...
