Hatchery controversy takes on new significance as salmon populations crashA recent study indicates that wild salmon may account for just 10 percent of California's fall-run chinook salmon population, while the vast majority of the fish come from hatcheries. The findings are especially troubling in light of the disastrous decline in the population this year, which will probably force the closure of the 2008 season for commercial and recreational salmon fishing. The role of hatcheries in the...

Biologist Pablo Cermeño Villanueva defended his PhD thesis at the University of the Basque Country (UPV/EHU), providing a tool to determine the age of anchovies with greater accuracy on a monthly or even weekly basis, thus enabling studies of the earliest phases of life to be undertaken. The European anchovy (Engraulis encrasicolus, Linneaus 1875) is a coastal pelagic species of great importance. Not only does it support an important fishing industry, but it is also...

A tough early life turns out to be a good thing for a fish, according to scientists at the University of California, Santa Barbara. They discovered that fish larvae that survive a long, rough, offshore journey eventually arrive at a near shore reef in good condition, and that they thrive afterwards. In contrast, locally produced young have a relatively easy life and they arrive on the reef (near the area where they were spawned) in a variety of conditions "“"“ from poor to good....

By Duffin, Christopher John Abstract The folklore associated with fish otoliths is traced from classical times to the present day for the first time. Otolithomancy involved divination of maritime weather conditions by consulting the properties and morphology of the "stones."

Modern applications...
