• farber-2018-ipm-fig1 Spawning migration in cod – a question of trade-offs

    The extensive spawning migration of Northeast Arctic cod was suggested to be counterbalanced by increased early-offspring survival, however we find in a study published in July in Marine Ecology Progress Series , that early offspring growth should be considered as another factor explaining this long-distance migration.

  • stige-2018-oilspill-fig1 Fishing can make fish populations more sensitive to oil spills

    Many heavily fished fish stocks are dominated by young and small fish. The reason is simple: the chance to reach old age is small. If the fisheries selectively target large fish, the dominance of young and small fish becomes even larger. Such skewed age and size distributions can make the fish populations more sensitive to detrimental effects of oil spills.
