Drinking and water absorption by the larvae of herring ( Clupea harengus) and turbot ( Scophthalmus maximus)
The efficiencies of water absorption from the guts of the larvae of herring ( Clupea harengus L.) and turbot ( Scophthalmus maximus L.) were estimated by two methods, The first method was based on the differences in the rates of accumulation, by drinking, and clearance from the gut of radiolabelled...
