Food consumption rate and gut evacuation processes of first feeding cod larvae In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983

Laboratory experiments with cod larvae (Gadus morhua L.) during optimum feeding conditions showed that cod larvae were sporadic feeders rather than continuous feeders. Digestion rate of copepod nauplii was less than 30 min, but varied with gut content volume. The cod larval gut evacuation rate varie...

Description
Summary:Laboratory experiments with cod larvae (Gadus morhua L.) during optimum feeding conditions showed that cod larvae were sporadic feeders rather than continuous feeders. Digestion rate of copepod nauplii was less than 30 min, but varied with gut content volume. The cod larval gut evacuation rate varied with food availability and state of digestion of the gut content. Criteria for larval gut content analysis for the evaluation of the cod larval feeding conditions in the sea are given.
