Central North Atlantic Nursery Used By Young Blue Sharks
2014-08-15 03:01:23

PLOS Blue sharks may use the central North Atlantic as a nursery prior to males and females moving through the ocean basin in distinctly different patterns, according to a study published August 13, 2014 in the open-access journal PLOS ONE by Frederic Vandeperre from University of the Azores, Portugal, and colleagues. Shark populations typically organize by location and separate by sex and size, but these patterns remain poorly understood, particularly for exploited oceanic species...

Master’s thesis research conducted from University of New England Marine Science Professor James Sulikowski's laboratory and published in the Public Library of Science-One (PLOS) suggests that spiny dogfish may remain in one region over the course of a year, moving to cooler waters in the summer and warmer inshore waters in winter, rather than migrating up and down the U.S. coast. In addition, their movement within the water column suggests distinct daily patterns and that this shark...

redOrbit Staff & Wire Reports - Your Universe Online While watching brightly-colored fish flit about in an aquarium tends to be a calm and relaxing experience, monitoring exactly where those aquatic creatures came from and what methods were used to capture them is an entirely different story. According to Jane J. Lee of National Geographic, the aquarium fish trade “is a global industry with no centralized database to track what gets bought and sold, and with no central governing...

Overfishing Leaves Fisherman Scraping The Bottom Of The Barrel In The English Channel
2014-07-14 03:07:45

University of Plymouth Research reveals practice of 'fishing down the food-web' Decades of overfishing in the English Channel has resulted in the removal of many top predators from the sea and left fishermen 'scraping the barrel' for increasing amounts of shellfish to make up their catch. Sharks, rays, cod, haddock and many other species at the head of the food chain are at historic lows with many removed from the area completely. These are some of the findings of a study led by...

Better Understanding Arctic Climate Change Based On Shark Teeth
2014-07-10 08:44:06

April Flowers for redOrbit.com - Your Universe Online Today, polar bears and other animals adapted to extremely cold environments inhabit the Arctic tundra. In the past, around 53 to 38 million years ago (the Eocene epoch), the Arctic was not a frozen tundra -- rather, it was more like a huge temperate forest with brackish water. This forest was home to a wide variety of wildlife, including the ancestors of modern-day tapirs, hippo-like creatures, crocodiles and giant tortoises....

Climate Change Could Hinder Fish From Finding Their Friends
2014-07-01 03:09:02

Society for Experimental Biology Like humans, fish prefer to group with individuals with whom they are familiar, rather than strangers. This gives numerous benefits including higher growth and survival rates, greater defense against predators and faster social learning. However, high carbon dioxide levels, such as those anticipated by climate change models, may hinder the ability of fish to recognize one another and form groups with familiar individuals. Scientists at the ARC Centre of...

The Shocking Story Of How Some Fish Evolved Electric Organs
2014-06-27 07:06:34

redOrbit Staff & Wire Reports - Your Universe Online By sequencing the genome of the electric eel for the first time, researchers have discovered how certain types of aquatic creatures were able to develop organs that allow them to produce electricity outside of their bodies. Publishing a paper in the latest edition of the journal Science, scientists from Michigan State University, University of Wisconsin-Madison, University of Texas-Austin and the Systemix Institute explain how...

Springer Review of mental ability shows fish are on par with most animals Do you still believe that fish are dumb and cannot feel pain? That we do not have to worry much about how they are cared for or caught? Think again, says Culum Brown of Macquarie University in Australia, in a review article in Springer’s journal Animal Cognition. The research notes that fish cognition and their sensory perception are generally on par with that of other animals. Brown therefore argues that more...

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...
