Growth and condition of post-moult male snow crab (Chionoecetes opilio) in the laboratory
We monitored soft-shell and hard-shell legal-sized male snow crabs sampled periodically in the field or fed to satiation at 4.5 jC in the laboratory for changes in nutritional condition. In soft-shell crabs, feeding resulted in a significant decrease of water content in all tissues. This decrease wa...
