Description
Summary:21. Distribution: C. harengus occurs in most boreal sea water or brackish areas in the northern hemisphere. 22. PoDulation: The herring is common in most of its ranges. It consists, however, of a number of subspecies (for example Clupea harengus pallassi in the Northern Pacific) or races (for example Atlanto-Scandinavian herring, Baltic herring, Downs herring) with clear behaviourial and morphometric differences. It is a pelagic schooling species, and as such, is sensitive to industrialised fishing methods. During the late 1 9 60’s and early 1 970’s, herring stocks in the Northeast Atlantic were severely depleted as a result of the over-intensive fishing of the species. Annual indices from international larval surveys had shown the rapid decline of the North Sea Herring during the early 1970’s, reaching a new [ow in 1975 [1]. An ensuing ban on the fishing of herring in the North Sea was implemented (1977-1 983), and whilst it was apparent that in many areas the fishing ban had been satisfactorily enforced, in others it was clear that illegal fishing was preventing the recovery of stocks [2].
