Pauly, D.
On the basis of historical trawl data, it is shown than the trawlable biomass in the Bay declined in the period from 1947 to 1980/81 to less than 20% of its original value, while total effort by the motorized fleet increased by more than 150 tons from 120 horsepower in 1936 to the present value of 18,800 hp. The catch data and other relevant information are reviewed by taxonomic group and by gear type
