This study focused on the reproductive biology of the velvet swimming crab, Necora puber (L.), and its implications for managing the fishery in the Orkney Islands, UK. According to gonadal observation, 50% of the population became sexually mature at 43.8

Seasonality of the reproductive cycle for Necora puber was determined using three biological indicators: extruding sperm plugs (mating period), extrusion of eggs (spawning period) and presence of empty egg capsules (hatching period). Sperm plugs were

The effects of temperature and salinity on embryonic development, and including diet on larval development of the swimming crabs Liocarcinus holsatus and Necora puber were investigated in the laboratory. The temperature-development rate relationships
