dc.description.abstract | In assessment and management of marine fish resources, representative data of statistically
good quality describing the actual catch are lacking for many fisheries. Even for the most
studied fisheries in the north Atlantic, the uncertainty regarding what is actually caught has
implications for management.
Fish stock assessments and sound advice in most cases rely on representative samples of
catches. Distant and high sea fisheries often suffer from poor sampling due to sampling
personal logistics. Consequently, stock assessment and management of marine fish resources
exploited by those fisheries are based on poor or scarce catch data. Presently, sampling at sea
are often random in time and place, and not necessarily representative with respect to the fleet
metier.
Biological sampling in distant waters is a challenge due to logistics and high costs. The use of
electronic scales onboard commercial fishing vessels opens for a new approach in data
collection. In recent years electronic scales measuring individual fish weights on deck have
been connected to GPS in combination with data on depth, fishing gear, logbook information
etc. This approach will link detailed data to auxiliary information on the fishery, thereby meet
the challenges of obtaining representative fishery data, continuous and full sampling
providing a sufficient data basis for fish stock assessments and subsequent fisheries
management for species found in distant waters. | no_NO |
