Rückwürfe in den Fischereien unter deutscher Flagge: Ergebnisse aus 6 Jahren Datenerhebungsprogramm am Institut für Seefischerei
Since 2002 Germany is obliged to collect fishery data to support the European Common Fishery Policy. Sampling of the com-mercial fishery under German flag is one duty within the EU fisheries data collection programme. During the past 6 years, 148 fishing trips were sampled by scientific observers onboard commercial fishing vessels to collect data on catch composi-tions with special emphasis on the proportions of landed and discarded fish. The results show that the proportion of discard is depending on the fishery. Highest discard rates were observed on beam trawl fishing trips. At the level of individual fishing trips, discard rates varied extremely within a fishery segment. Highest variations were found in the beam and bottom otter trawl fishery. In contrast, the discard rates in high-seas fisheries were low
Die Fischerei im Nordostatlantik im Jahre 2004
Since 1990 North-east Atlantic fish species – arctic cod, saithe, haddock, redfish and Greenland halibut – have been investigated by on-board observers on the German commercial trawler FMS Kiel. These investigations are part of the national data collection regulation established by the European Union in recent years. Collected data are basic data for the scientific assessment of these important fish stocks of the European fisheries. The results of the observed cruises are used by the Arctic Fisheries Working Group of the International Council for the Exploration of the Seas (ICES). Biological investigations were carried out in Norwegian waters and the Barents Sea (ICES Divisions IIa and IIb) on board FMS Kiel in January to March and in August/September 2004. This report presents results of these cruises and an overview about the general fishery situation in 2004
Aktivitäten des nationalen Fischereidatenerhebungsprogramms im Jahr 2004
Based on the EU Regulation 1543/2000 for the improvement
of quantity and quality of fishery data the Federal
Ministry for Consumer Protection, Food and Agriculture has
initiated a national data collection programme, executed
by three institutions, Federal Research Centre for Fisheries
(BFAFi), Federal Agency for Ariculture and Food and the
Federal Research Centre Agriculture, co-ordinated by BFAFi.
In 2004 samples have been taken from 943 hauls during
29 commercial fishing trips; 357 000 fish have been measured. From 2002 to 2004 the number of length and weight
and measurements, and age determinations could increased
by 32, 65 and 156 % resp. Pilot inquiries have been
carried out to prepare also the collection of economical
date of fishing vessels and of fish processing plants from
2006
Nationales Fischereidatenerhebungsprogramm: Aktivitäten und Ausblick
Within the frame of the EU Data Collection Regulation (DCR), Germany is obliged since 2002 to collect basic fisheries data to support the Common Fisheries Policy. Various governmental institutions are involved in the collection of landings and effort data, biological and economic data of the German fisheries. About 200 trips on commercial fishery vessels were sampled from 2002 to 2006. Additional stock data are collected on research surveys. The landings of cod in the recreational fisheries in the North and Baltic Seas were recorded within a pilot study. In order to assess the economic situation of the fishing fleet and processing industry, economic data were collected. The collected data are being stored in a national database and being made available for scientific working groups. At present, the legal regulations within the DCR framework are being reviewed and adapted to the changing requirements of fisheries management
