A preliminary report on the natural occurrence and ecology of Atlantic halibut (Hippoglossus hippoglossus) postlarvae and young immature stages
Surveys designed to capture Atlantic halibut, Hippoglossus hippoglossus, postlarvae and young immatures were carried out around Sørøya in North Norway in 1985, 1986 and 1987. Hydrographical conditions and the current features in the area were also investigated. The ichthyoplankton trawls (MOCNESS, T...
