    Description: The spring session of ACFM gave advice for a number of stocks in the North Atlantic, North Sea and Baltic. The situation is given here for stocks of higher importancefor the German fishery. These are: Blue Whiting: A short term upwards trend is observed, which, however, will not last very long, due to too intense fishing. Cod in Kattegat: Stock is outside safe biological limits. No immediate recovery in sight. Cod in Sub. Div. 22– 24 (Baltic): Stock is outside safe biological limits. Due to weak recruitment not immediate recovery in prospect. Greenland Halibut: Stock outside safe biological limits and still in downward trend. Herring (atlanto-scandian, Norw. spring spawner): Stock inside safe biological limits, weak recruitment of the past 5 years will, however, lead to a reduction of the biomass. Redfish: Generally decreasing tendency observed, a reduction of the fishery is recommended.

    Description: The northern European fish stocks are assessed annually by ICES working groups. The results are evaluated biannually in two meetings of the Advisory Committee for Fisheries Management (ACFM) at ICES. Based on the working group assessments, ACFM formulates an advice for fisheries management and suggests a total allowable catch (TAC) which is based strictly on biological grounds. The summaries of the state of some selected stocks which are given here, are derived from the ACFM advice, formulated during the most recent May 1998 meeting. For many of the fish stocks the precautionary approach is still in the process of implementation, and only for some of them the management and target reference points have been fully defined.

    Description: The North-European fish stocks are assessed annually by ICES working groups. The results are evaluated twice annually in two meetings of the Advisory Committee for Fisheries Management (ACFM) at ICES. Based on the working group assessments, ACFM formulates an advice for the fisheries management and suggests a total allowable catch (TAC) which is based strictly on biological grounds. The summaries of the state of some selected stocks which are given here, are derived from the ACFM advice, formulated during the most recent October 1999 meeting. For many of the fish stocks the precautionary approach has been implemented now, and for most of them the target reference points have been defined. As a result, most of the stocks are outside safe biological limits or are harvested in disaccordance with the precautionary approach. Only 10 stocks of those evaluated during this autumn meeting were found to be within safe biological limits.

    Description: The October meeting of the ACFM of ICES gave advice for a number of North-Atlantic fish stocks. The results of the most important stocks are given here from the perspective of German fishery management. The are chiefly North Sea plaice and sole, for which a reduction of 25 % of the fishing mortality (F) is recommended for 1998, North Sea saithe (minus 20 % in F), while North Sea cod is in the process of recovery and North Sea haddock is inside safe biological limits. The mackerel stock of the North Sea has not yet recovered, while the western mackerel stock as an entity has stabilised at a level of about 2.3 million t.

    Description: Based on the results from egg and larvae surveys, mackerel and horse mackerel are thought to form three more or less distinct stocks each in the North Sea and in the waters west of the British Isles. These are firstly the southernstocks in the southern part of the English Channel, Celtic Sea and Bay of Biscay, secondly the North Sea and finally the western stocks of both species, loeated between the Shetlands and southern Norway. It is argued here that in view of the high mobility and the extended seasonal migrations of both species a c1ear separation of the stocks can hardly be maintained. In this context the results of the 1995 mackerel and horse mackerel egg survey to the southern spawning location is presented.

    Deutsche und internationale Bestandsuntersuchungen an Heringen mit hydroakustischen Methoden (2021)

    Description: The international hydroacoustic herring survey in the North Sea is carried out since the early eighties with Dutch, Scottish, Danish und Norwegian contribution. Since 1994 Germany also participates in this survey on a regular basis and has taken over a sector in the easter part between the Dogger Bank and the Danish coast. This area is known for the abundance of chiefly juvenile herring and sprat. During the 1995 cruise some 420000 t of herring were found here, most of them being juveniles of age group I. Analyses of plankton hauls showed that planktonic echos were not caused by juvenile herring, instead the echos were apparently produced by small pelagic gastropodes of the genus Spiratella.
