The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. Their findings appear in a current online issue of the journal Freshwater Biology where they describe experiments that examined some effects of fisheries management practices now in use in California mountain lakes where fish do not naturally occur. The research has value...

Attempts to avoid dams decrease survival in adult fishScientists have discovered that management efforts intended to assist migrations of salmon and steelhead trout can have unintended consequences for fish populations. Juveniles that are transported downstream on boats can lose the ability to migrate back to their breeding grounds, reducing their survivorship and altering adaptations in the wild.Transportation programs have been in place for over three decades to improve the survival of fish...

Most of California's native salmon, steelhead and trout species face extinction this century without quick action to provide proper habitats, a study found. Twenty of 31 species of prized fish are in sharp decline, including the Sacramento River winter run of Chinook salmon, coastal Coho salmon and the Sierra Nevada golden trout, the San Francisco Chronicle reported. Our fish need cold, clean water to survive, but they're getting less and less of it, said University of California, Davis,...

News in brief ENVIRONMENT The collapse of sea trout numbers in the British Isles has left scientists baffled as to the cause, with hauls in Scotland at a 50-year low. Last year, catches on the river Spey, the largest river on the Moray Firth system in north-east Scotland, fell by 52 per cent. This year numbers are expected to be even worse. On the river Dee take rates are 46 per cent down while the river Ness has seen catches slump 10-fold since the 1990s. In Wales, experts say the size of...

Six popular fishing areas in Utah now have fish-consumption advisories because of concerns about mercury. The advisory released Tuesday by the Utah Department of Health says that since 2000, fish have been tested for the heavy metal in 261 bodies of water statewide, including 192 streams and rivers and 69 lakes and reservoirs. Of those, 15 had elevated levels of mercury, and advisories have been issued for them. In all cases where high levels of mercury have been found, pregnant women and...
