Norwegian spring-spawning herring & Northeast Arctic cod - 100 years of research and management

This book describes how fisheries, fisheries science and management for Norwegian spring-spawning herring and Northeast Arctic cod developed during the 20th century. Both populations had serious declines in stock size and yield due to overfishing. The herring stock was in a state of collapse for about 20 years. Management measures introduced during the two-three years last decades made both stocks recover in the 1990s.
