A model to describe gastric evacuation in cod (Gadus morhua L.) fed natural prey
A model that describes single-meal evacuation in Atlantic cod, Gadus morhua L., fed whole natural prey was developed and tested using a large set of data. Evacuation rates and clearance patterns were derived for four important prey. Results of a Monte Carlo error analysis suggested that: (i) the cle...
