Size and temperature-dependent variations in intermolt duration and size increment at molt of Northern Shrimp, Pandalus borealis
Growth of Pandalus borealis post-larval stages was measured in relation to size and temperature. Growth characteristics, including intermolt period (IP), molt increment (MI) in size and mass, and tissue allocation in juvenile, male, and female shrimp, were evaluated at 2, 5, and 8°C, the temperature...
