Robot Fish Sniffs Out Underwater Pollution
2012-05-23 04:35:13

Michael Harper for RedOrbit.com The latest advancement in pollution-seeking technology looks like a fish and swims like a fish, but gathers data like a robot. These pollution-hungry robot fish are the product of research from British BMT Group and SHOAL research and are now be studied as they swim the seas of Gijon, Spain. Luke Speller – who plays dual roles as SHOAL Project Leader and Senior Research Scientist for BMT Group – said of the research: “SHOAL has...

One Quarter Of Grouper Species Being Fished To Extinction
2012-05-09 13:03:08

An international team of scientists has made a global assessment of threats and extinction risks in the multi-billion dollar grouper industry Groupers, a family of fishes often found in coral reefs and prized for their quality of flesh, are facing critical threats to their survival. As part of the International Union for Conservation of Nature (IUCN) Species Survival Commission, a team of scientists has spent the past ten years assessing the status of 163 grouper species worldwide. They...

Changing the conditions that zebrafish are kept in could have an impact on their behavior in animal studies and the reliability of results, according to scientists from Queen Mary, University of London. Zebrafish, like rats and mice, are often used by neuroscientists to explore mechanisms controlling behavior and in the search for new compounds to treat behavioral disease such as addiction, attention deficit disorders or autism. It is known that housing and handling affects the results...

Rebel Coelacanth Discovery Forces Rethink On Their Evolution
2012-05-03 09:21:49

Canadian researchers have discovered a new species of Triassic coelacanth, a fish presumed extinct until a population was found off the coast of Africa in the 1930s, while digging through a trove of museum fossils, reports Jennifer Viegas for Discovery News. The coelacanth (pronounced SEE-la-kanth) is a primitive, slow-moving fish that is often referred to as a living fossil because it has existed largely unchanged for more than 300 million years. But the new discovery, dubbed Rebellatrix,...

Smalleye Pigmy Sharks Get Their Glow On For Camouflage
2012-04-27 04:40:45

Jason Farmer for RedOrbit.com There are a number of sharks that have specialized light-emitting organs on their undersides that allow them to glow in the darkest depths of the ocean. In fact, according to researchers, at least 10% of all known shark species are luminous, and this ability is one of the most mysterious areas of shark biology. A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain...

Team of female scientists develop sophisticated numerical model to study larval behavior, fill ecological gap The behavior of marine larvae is central to fully understanding and modeling the pelagic (open ocean) stage for many coastal organisms. For the first time, a numerical study conducted by the University of Miami (UM) incorporates horizontal larval fish navigation skills into realistic 3D flow fields, creating a powerful tool that spells out how larvae use environmental cues to find...

A task force that conducted one of the most comprehensive analyses of global “forage fish” populations issued its report this week, which strongly recommends implementing more conservative catch limits for these crucial prey species. The Lenfest Forage Fish Task Force calls for the harvest reduction of sardines, anchovies and other forage fish so that they can continue to serve as critical prey for larger species, including salmon, cod and tuna, as well as for dolphins, whales,...

Forage fish twice as valuable in the water as in the net Fishing for herring, anchovy, and other "forage fish" in general should be cut in half globally to account for their critical role as food for larger species, recommends an expert group of marine scientists in a report released today. The Lenfest Forage Fish Task Force conducted the most comprehensive worldwide analysis of the science and management of forage fish populations to date. Its report, "Little Fish, Big Impact: Managing a...

The prowfish (Zaprora silenus) is a subtropical species of a perch-like fish found in the northern Pacific Ocean. The range of the prowfish is from the Aleutian Islands, Alaska to Kamchatka, Russia, from Navarin Canyon in the Bering Sea to Hokkaido, Japan and Monterey, California. The preferred habitat of the prowish is rocky bottom at a maximum of 2,200 feet in depth where they spend most of their adult life. Prowfish can grow to a length of 40 inches or more having an elongated body that...

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...

Little tunny, Euthynnus alletteratus
2013-03-28 14:07:39

The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...

Image Credit: WA Djatmiko/Wikipedia (CC BY-SA 3.0, 2.5, 2.0 and 1.0) The African sharptooth catfish is native throughout Africa, and the Middle East, and in the 1980’s it was introduced all over the world. This catfish lives on muddy bottoms in freshwater lakes, rivers, swamps, man-made habitats, and occasionally found in urban sewage systems. This species is able to crawl across dry ground to another body of water when one pool dries up. It is also able to survive for long periods of...
