In 1998 the longtime series of the standardized bottom trawl surveys conducted in the western Baltic (ICES Sub-division (SD) 22 and 24 since 1978) during spring and autumn and also in the eastern Baltic (ICES Sub-division since 1993) during spring were continued. The results of the surveys as well as those of a sampling programme carried out on board of commercial cutters (mainly financed by an EU study project) and on the market, the investigation of the survival rate of the discards, and the landing statistics are the basis of the analysis of the German and international cod fishery in 1998. The German cod fishery was concentrated on the ICES SD 22 and 24 (total landings 9722 t). The total landings from the fishing grounds east off Bornholm, the traditional German fishing ground, amounted only to about 1270 t. The German cod quota was utilized at 64 %. The fishery in the ICES SD 22 and 24 was characterized by a discard rate of undersized cod of 13 %. That corresponds to about 7.3 million specimens of 0-group, one- and two-years-old youngfish, respectively. The total international cod landings of the Baltic amounted to 101 500 t. In comparison with 1997 (total landings 129 600 t) the landing decreased by 23 %. The percentage utilization of the cod TAC (1998: 140 000 t) amounted to 74 % in 1998.

In der Zeit unzureichender Nahrungsmittelversorgung nach dem Zweiten Weltkrieg nahmen schon wenige Wochen nach Kriegsende die ersten Fischereifahrzeuge wieder den Fang auf. Unzureichend ausgerüstet und z.T. nur provisorisch wieder für Fischereizwecke zurückgewandelt, bemühten sie sich, in zugewiesenen, begrenzten Seegebieten zu fischen und so ihren Versorgungsbeitrag zu leisten. Einen möglichst großen Anteil dieser Fänge als Konsumware der hungernden Bevölkerung direkt zukommen zu lassen, das war ab Spätsommer 1945 das Hauptziel von Fischereibiologen, Lebensmittelchemikern und Fischereitechnikern, die sich zum größten Teil in Hamburg zusammen gefunden hatten. Sie gehörten zu den Nachkriegsresten von vier Instituten der ehemaligen Reichsanstalt für Fischerei (1938-1945): dem Institut für See- und Küstenfischerei aus Hamburg-Altona, dem Institut für Ostseefischerei aus Swinemünde, dem Institut für Fischverarbeitung aus Hamburg- Altona, dem Institut für Netzforschung aus Lötzen (Ostpr.). Schon ab Herbst 1945 gingen die vier Institutsreste in die Verwaltung der Hansestadt Hamburg über und wurden mit kleinen, aber regelmäßigen städtischen Etats arbeitsfähig.

27 Jahre nach Durchführung der ersten Internationalen Konferenz über Fischinspektion, die von der FAO in Halifax, Kanada, 1969 veranstaltet wurde, war das Nationale Fischerei Institut der USA in Kooperation mit anderen Institutionen Sponsor und Organisator einer zweiten Konferenz über Fischinspektion und Qualitätskontrolle. Diese Konferenz fand vom 19. - 24. Mai 1996 in Arlington, Virginia, statt. An 3 Tagen war die Konferenz durch eine Ausstellung begleitet, auf der 26 Aussteller, Consulting-Firmen, Handelslaboratorien und Universitätsinstitute, ihr know how und ihre Dienste auf dem Gebiet der Fischinspektion und Qualitätskontrolle offerierten. Die Konferenzteilnehmer hatten während der Konferenzpausen auf diese Weise die Möglichkeit, sich über Neuheiten und Leistungsangebote zu informieren.

Several technologies have been disseminated to the rural populace of which few were adoptable while others were above their reaches. The adoption-rejection behaviour of the people of Monai community formed the basis for this study. Twenty women fish processors were interviewed using standard questionnaire. The study discovered that the women fish processors used the new introduced Better Life Programme Banda in rotation for even coverage. The use of new Banda has a positive effect on the quantity of fish processed and income. Additional two basins were processed on weekly basis with an income of N1,000.00 over the previous processing technology. No women processor however had the new Banda on individual basis for cost. Hence rural people adopt a technology that is cheap and simple but conforming to their traditional practices and values. Therefore any innovation intended for the rural populace should take cognizance of their socio-economic and cultural factors

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.

Until now observations on the temporal variation of size of freshwater copepods have not provided much information. Other observers only mention in passing this or that phenomenon from which it is possible to deduct termporal variations. In this study Cyclops strenuus s.l., a freshwater species of fairly wide distribution, is studied in two water bodies. The author studies the systematic, placing of inhabitants described as C. strenuus Fischer in both locations, their annual life cycle, and their annual size variations.
