The effect of the plaice fishery on the stock of undersized plaice and its influence on the yield of the plaice fishery in the North Sea
What may be learnt from the development of the fishery and of the stock of plaice in the North Sea may be summarised as follows:- An intensive fishing destroying a considerable number of undersized plaice on the nursery grounds, does not — even if carried on over a rather long series of years — destroy the productivity of the stock; but, on the other hand, it seems as if it cannot increase the productivity. An increase of the productivity can be produced by protection of the undersized plaice on the nursery grounds.
