The effect of temperature on the development, growth and survival of Atlantic cod (Gadus morhua) during early life-histories
For poikilothennic animals, and in particular those that inhabit aquatic habitats, temperature has a significant effect on all life processes. The purpose of this research was to investigate the contribution of temperature on embryonic development and survival and its effect on vital rates. Of parti...
