Abstract

Havsfiskelaboratoriets trålexpeditioner i Västerhavet (Skagerrak och Kattegatt) genomförs två gånger årligen, i kvartal 1 och 3. Den franska bottentrålen GOV används för provtagningen av demersala arter. Under kvartal 1 används också en MIK-trål nattetid för provtagning av fisklarver. Under denna expedition gjordes totalt 45 giltiga tråldrag i hela området med GOV-trålen, 26 i Skagerrak och 19 i Kattegatt. Ett extra kalibreringshal utfördes också. Den totala fångsten inkluderade 60 olika fiskarter. På de viktigaste kommersiella arterna insamlas data på individnivå, vanligen längd, vikt, kön och könsmognad samt otoliter för åldersanalys. Totalt provtogs 4639 individer från 11 olika arter med avseende på ålder samt 1204 st från två arter med avseende på vikt.

The Institute of Marine Research is responsible for the trawl survey in the Skagerrak and the Kattegat areas of the North Sea. This survey is conducted twice annually, in quarters 1 and 3. The French bottom trawl GOV is used for sampling demersal species while a MIK trawl is used for sampling fish larvae at night in Q1 only. During this survey a total of 45 valid hauls were towed in the whole area using the GOV-trawl, 26 in the Skagerrak and 19 in the Kattegat. One extra haul was towed for calibration purposes. The total catch included 60 species of fish. The biological sampling, which includes collection of otoliths for age analysis, was done on the most important commercial species. In total 4 639 otoliths were collected from 11 different species. In addition, length and weight data from 1204 specimens were collected for two species.
