We continue with tagging cod and lobsters in Store Lungegårdsvannet. Additionally, we also started to tag pollack and take blood samples from both fish species. In contrast to cod and lobsters that both live benthic and have well defined home ranges, pollack is a pelagic fish species that uses wide coastal areas as habitat. Our work will help us understand how the upcoming restoration of a highly polluted urban area will affect these species with different ecological niches.
We were lucky to recapture some individuals that have been tagged last year and it was great to see how well they recovered from surgery with completely healed scars.
