Seasonal variations of lipid fatty acids of boreal freshwater fish species.

摘要: Abstract 1. The fatty acid levels of muscle and liver lipids perch, vendace rainbow trout ( Salmo gairdneri ) cultivated in the same area (for comparison) were monitored. 2. total lipid content perch Perca fluviatilis Coregonus albula was less than 50% that a seasonal variation clear only vendace. 3. relative amounts polyunsaturated acids as well omega-3 higher trouts.
