Correlation of plasma IGF-I concentrations and growth rate in aquacultured finfish: a tool for assessing the potential of new diets
A recently developed radioimmunoassay (RIA) for measuring insulin-like growth factor (IGF-I)in a variety of fish species was used to investigate the correlation between growth rate and circulating IGF-I concentrations of barramundi (Lates calcarifer), Atlantic salmon (Salmo salar)and Southern Bluefi...
