Spatial and temporal patterns in recruitment of shrimp Pandalus borealis in the Barents Sea
The shrimp spawn in autumn and the eggs are carried as out roe by the females until spring when the larvae hatch. Within a period of 2-3 months the shrimp larvae settle to the bottom. Today’s assessment and forecast of the shrimp stock productivity and potential fishing yields is weak. This is partl...
