Title

Release and recapture data from cod tagged in the North Sea from 1961 to 2015

Abstract

Release and recapture data relating to cod tagged and released in the North Sea (ICES Subarea 4). Between 1961 and 2015, a total of 22,573 cod were tagged and released using either conventional marker-ID tags and in the more recent years of the dataset, electronic data storage tags (DSTs), of which 6,703 tags were subsequently returned. For tagged fish that were recaptured as much information as possible was recorded, namely the recapture date and location, length, weight, sex and maturity. Otoliths (ear stones) were removed for age determination purposes and other studies. These data are used to provide information for studies relating to fish behaviour, growth and identification of stock units.

Lineage

Cod suitable for tagging were caught using either research or commercially chartered fishing vessels. After each fish was tagged with a uniquely numbered conventional marker-ID tag, their length, weight, health state, release date and position were recorded before being released. From 1999 onwards, cod were also tagged using electronic Data Storage Tags (DSTs), which provide additional information that can be used to gain further insight into the fish’s behaviour. Release and recapture data of these tags were also captured to the `Cefas Tagged Fish Database`_. Although these data have been subject to quality assurance, the provided data does include known erroneous data (e.g. recapture position, time at liberty), some of which have been identified and marked as such. .. _`cefas tagged fish database`: http://data.cefas.co.uk/#/View/206
