The rising demand for shark fin soup in Asia is spurring illegal fishing and contributing to a plunge in stocks, according to a report on Monday. The Australian government and the wildlife trade-monitoring network Traffic, published the study urging governments to crack down on illegal catches. Registered legal shark exports totaled $310 million worldwide in 2005, up from $237 million in 2002. "As the world's demand for sharks continues to grow, shark populations are plummeting," the report...

Atlantic sharks may have hope for the future thanks to an international team of scientists who want to ban the catching of eight species. They want to add a strict limit on the catch of two others to try to prevent population crashes. Sharks are vulnerable to over-fishing because they reproduce and grow slowly. However, there are currently no international limits on shark catch according to the non-profit Lenfest Ocean Program. The group found in a study that 10 species of Atlantic sharks...

Canadian and U.S. biologists say they have, for the first time, successfully tracked juvenile salmon in both rivers and oceans. The achievement, officials said, was made possible by newly developed miniature tagging and tracking technologies that can follow small salmon over vast distances. "It may have been one of humankind's first ponderings: the fish that got away -- where they come from, where they go and what happens to them in between," said Jim Bolger, executive director of the...

The European Union is granting more protection to exotic deepwater fish, some of which can live up to 150 years. Fisheries ministers agreed to major quota cuts for the next two years.Exotic fish like forkbeard, black scabbardfish, greater silver smelt and roundnose grenadier grow and reproduce far more slowly than fish in shallower waters.These deep sea species have become an attractive catch as trawlers switch from their regular fishing grounds due to the depletion of mainstay commercial...

According to Australian scientists, antibodies found in shark blood could potentially be used to fight cancer. Sharks have antibodies - molecules that fight disease - that are exceptionally adaptable, and tough. Researchers believe they can harness these attributes and use them to slow the spread of cancer. They hope the idea can lead to a new line of drug treatments. The team of researchers found that shark antibodies are capable of withstanding very acidic or alkaline conditions, and are...

By Frank Urquhart A STAGGERING five miles below the surface of the Pacific Ocean, scientists had been hoping, at best, to film a solitary fish able to exist in the deepest reaches of the world's seas. And they assumed anything they succeeded in capturing on film would almost certainly be a "monster" - a weird and ugly specimen similar to the shrivelled samples of deep-sea species preserved in the world's marine research institutes. But a team of marine biologists, led by scientists at...

The Atlantic bluefin tuna is the largest and most sought-after of all tunas, weighing as much as 1,400 pounds and capable of fetching as much as $50,000 or more in Asian markets where its meat is a prized commodity, one big reason why its numbers have declined precipitously since the 1970s. New research findings reported in Science have critical implications for how bluefin tuna are managed on both sides of the Atlantic Ocean. A team of international researchers led by Dr. Jay Rooker of Texas...

In an attempt to help conservation of marine animals and aid in climate change monitoring, scientists using DNA have catalogued and described 100 new species of sharks and rays in Australian waters. More than 90 of the newly named species were identified by scientists in a 1994 book "Sharks and Rays of Australia" but remained scientifically undescribed. One rare species of carpet shark catalogued was found in the belly of another shark. A revised 2009 edition of the book by Australia's peak...

Conservationists agree that major changes to rules on shark finning are needed to preserve the health of the world's shark populations. Confusing regulations and poor enforcement mean rule breaking is common, according to campaign group Oceana. Actor and activist Ted Danson said proper management could rescue the species in decline. Over half of ocean-going sharks, and about a third of European species, are threatened with extinction. Danson said the basic problem is it's a fishery that's not...

By Anonymous A state official put it best: A federal report that documents a continued decline in some species of groundfish despite years of regulation was "extremely frustrating." After reducing the number of fishing days, staying out of certain areas and using nets with bigger mesh, the stocks of some species have not rebounded as hoped, leading to what are expected to be even stricter limits next fishing season. For commercial fishermen and the remaining Maine businesses 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...

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...

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...
