Phenology of otolith zone formation in North Sea cod : associations with growth, environmental variation and stable isotope chemistry

North Sea cod (Gadus morhua) are a commercially important species and have been subject to substantial fishing pressure. This has resulted in significant population declines, and a requirement for management strategies to facilitate the recovery of the stock. Environmental variation may influence fish in a number of ways including spatial ribufion, growth performance and recruitment. This study aims to assess variations in phenology of North Sea cod otolith zone formation with ambient water temperatures. Links with somatic growth and metabolism are explored and implications discussed.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
