Paper of the Month - Reproductive strategy of a migratory fish stock: implications of spatial variations in natural mortality
The reproductive strategy in a migratory marine fish may be influenced by spatial variations in mortality in early life-stages. In a new study a team of scientists, including Hjort Centre researchers Geir Ottersen and Frode Vikebø, examine how spawning time and location affect offspring survival and growth of Barents Sea cod. A drift model for early life-stages of the cod is combined with empirical estimates of spatial variation in mortality at two different life-stages. The study is now available online in Canadian Journal of Fisheries and Aquatic Sciences.
