A check of traditional parameters based on fishing effort in the surface fishery of juvenile albacore in the Northern Atlantic
In this paper, the authors try to check if there exists a relationship between catchability and stock size in the juvenile albacore surface fishery in the North Atlantic stock. The conclusions are that this relationship does not seem to take place; fishing effort reflects very well F, and CPUE chang...
