Spawning season of the Atlantic halibut (Hippoglossus hippoglossus) in northern Norway
The spawning season of the Atlantic halibut ( Hippoglossus hippoglossus ) was examined by studying maturity stages in adult fish in Sørøysund, Finnmark, and in Salten/ Folda, Nordland, during 1956–1960, and by sampling eggs from the plankton in Malangen, Troms, during 1983–1986. These three sites ar...
