However, as Western Baltic herring in general show closer genetic relationships with North Sea populations than with other Baltic Sea populations (e.g. [14,16]), our results thus constitute a separate line of evidence that spawning time divergence may be associated with divergent selection at the genomic level. We have not demonstrated that spawning time differentiation is the main driver of

The article concludes by arguing that, although the UK public authorities (notably the Herring Industry Board) might reasonably be criticized for pursuing a development strategy which resulted in economic and biological over-fishing, the international regime of fisheries management which prevailed at the time gave them little choice but to adopt a pro-active approach to technical innovation.

Lessons learned from stock collapse and recovery of North

The management of North Sea herring, after a moratorium was lifted in 1981, is evaluated with respect to effects on supply, stock level, and fishing effort. Under optimal management, the results imply that the fishery should have stayed closed until 1983, a conclusion that is independent of harvesting relationship used. Whether open access leads to total depletion or not is seen to depend on
