21-26 October The Marine Research Institute in Reykjavik Iceland (MRI) conducted a survey on a research vessel and tagged over 200 redfish with the Underwater Tagging Equipment (UTE) made by Star-Oddi.
The tagging cruise was conducted with a bottom trawl at a well known fishing ground, SW of Iceland. During the survey redfish was tagged at depths of more than 500m. The fish lengths were estimated, from video data from the UTE to be from 32-45 cm. There has already been one recapture of tagged redfish from this latest tagging cruise, the redfish was tagged at approximately 500m depth which confirms that the redfish survives this treatment. These results are very promising and the UTE will allow the researchers to get more information associated with the unknown stock structure of Sebastes mentella redfish, stock components in the Irminger Sea and along the shelf and slopes of Iceland, Greenland and the Faeroe Islands. As long as the stock structure and possible interrelation between possible stock components remain unknown, it will always be difficult to assess the status of the stock(s) and to give reliable advice on how to manage this important resource.
