Bacteria in the gut of juvenile cod Gadus morhua fed live feed enriched with four different commercial diets
Abstract Atlantic cod, Gadus morhua L., larvae were fed rotifers, Brachionus plicatilis and Artemia franciscana enriched on four different commercial media, using the manufacturers' protocols. Pooled samples of 20 cod larvae were homogenized, diluted, and plated out on Petri dishes. The number...
