Wirtschaftlichere Befischung des Patagonienhechtes wünschenswert?
Dueto the results of 2 exploratory cruises of R.V. "Walther herwig" and the findings of the M.S. "Weser" the hake population on the Patagonian shelf is estimated to be about 3 mill. ts. The maximum sustainable yield could be 1 mill. ts. From the population - dynamical point of view at the moment there is a need to increase the catches for the benefit of the whole stock. On the other hand it is necessary to use a minimum mesh size of 120 mm, for economical reasons too, based on selection-experiments, which were also found to be the most optimal for the SE-Atlantic hake. Remarks on distribution, age - length relationship are made.
