Climate Change and New Potential Spawning Sites for Northeast Arctic cod

摘要: In this study we investigate both historical and potential future changes in the spatial distribution of spawning habitats for Northeast Arctic Cod (NEA cod) based on a literature different physical factors from downscaled climate model. The approach to use high resolution regional ocean model analyze sites is new provides more details about crucial than global low can. evaluated with respect temperature salinity along Norwegian coast during last decades shows acceptable agreement observations. However, does not take into consideration biological or evolutionary which also have impact choice sites. Our results RCP4.5 scenario suggest that will be shifted further northeastwards, locations at Russian close Murmansk over next 50 years, where temperatures many century were limiting factor spring. gives above chosen lower critical minimum value larger areas today indicates extensive there. Dependent upper boundary, may become traditional south Lofoten. Finally, observed long-term latitudinal shifts recent indirectly linked through shift sea ice edge corresponding available ice-free predation habitats, control average migration distance We therefore acknowledge limitations defining might proxies other biophysically related factors.
