The University of Florida, keeper of the world's shark attack records, is also now overseeing a national records collection for another toothy marine predator: the sawfish. Distinguished by a long rostrum or "saw" that makes it a popular curio item and gives it its name, the sawfish has become a historical and cultural icon that is rapidly disappearing, said George Burgess, a UF ichthyologist and curator of both the International Shark Attack File and the newly expanded National Sawfish...

A new bilingual online information system created by D. Ross Robertson, staff scientist at the Smithsonian Tropical Research Institute, and Coeus Knowledge Systems makes it possible for conservationists, sport fishers, tourists, researchers, students and resource managers to identify and generate publishable maps for 1,287 tropical eastern Pacific shore fish species. Shorefishes of the Tropical Eastern Pacific Online Information System is hosted by the Bioinformatics Office of the institute...

Sharks in the North Atlantic are in serious danger of being driven out of existence due to the fishing activities of nations such as Spain, Portugal, France and Britain, according to Swiss-based International Union for Conservation of Nature (IUCN). The group said action must be taken immediately in order to change the current downward trend. Among new changes, the IUCN said tougher fishing controls would be needed in the European Union. A zero catch for spiny dogfish and all deepwater sharks...

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...

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...

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...
