Gut evacuation rates in Nephrops norvegicus (L., 1758): laboratory and field estimates
Estimates of gut evacuation rates of Nephrops norvegicus (Linnaeus, 1758) (Crustacea, Decapoda) were obtained during laboratory and field experiments. Individuals were collected off the south coast of Portugal in December 1997 and July 1998. Gut evacuation rates (R.h(-1)) were calculated from the sl...
