Goergous Food Is Fish Fry

The entire North American population of rainbow trout with extinction if the temperature rises and global warming, millions of dollars of commercial-free and Inland Fisheries influences, a new study finds.Peter Biro of the University of Technology, Sydney, Australia, and colleagues experimentally created trout populations in British Columbia, Canada, studied for two consecutive years, eight and nine to the population, or copying. In 1998, the temperature a few degrees warmer than the optimum for trout growth (21-22 ° C), while the 1999 is close to the optimum temperature (17.5 ° C). Only half as many young trout - about 4% of the total - survived in 1998 compared to 1999.Young brown trout feed near the shore to avoid predators, while striving to grow enough to cope with winter. Their metabolism increases the water warms up, but they have to go through the same weight. But the more they swim in search of food, they are more vulnerable to predation by adult trout, the researchers found. The study is the first effects of climate change, conservation of resources to analyze, geographically isolated, and the physiological and behavioral mechanisms to describe
