Atlantic Salmon Ecology is a landmark publication, both scientifically important and visually attractive. Comprehensively covering all major aspects of the relationship of the Atlantic salmon with its environment, chapters include details of migration and dispersal, reproduction, habitat requirements, feeding, growth rates, competition, predation, parasitsm, population dynamics, 606 $aAtlantic salmon$xEcology 606 $aFishes$xEcology 615 0$aAtlantic salmon$xEcology. 615 0$aFishes$xEcology. 676 $a597.5/617 676 $a597.5617 701 $aAas$b Øystein$0946286 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910829856103321 996 $aAtlantic salmon ecology$92137926 997 $aUNINA
