Preliminary results of investigations of the Federal Republic of Germany on Notothenia rossii marmorata (Fischer, 1885) in January/February 1985
A bottom trawl survey carried out by FRV "Walther Hervig" in January/February 1985 was used to collect further basic data needed for stock assessment purposes, to assess the actual size of Notothenia rossii around South Georgia and Elephant Island and the extent to which the measures adopted by CCAMLR to rebuild the stock around South Georgia might be successful. Although reported catches in recent years have been low, N. rossii around South Georgia is still largely affected by the fishery. Stock size is probably still less than 10% of the pristine stock, Mean length in the catches has only slightly increased since 1981/82 and is still close to length at sexual maturity. The major part of the population consisted of age classes V – VIII. It seems doubtful if the conservation measures adopted in 1984 will really help to rebuild the stock around South Georgia.
