Abstract
In a short time feeding experiment it was shown that the liver weight of cod was significantly reduced in prawn-fed cod compared to sand-eel-fed cod. The dry weight and the protein content of the muscle were not significantly reduced. It is concluded that short time energy deprivation of cod primarily affects the liver. The results futher support the view that the food type and ration of cod can produce anomalous effects in field studies of e.g. parasite induced liver weight decrease in cod.
Sammendrag
I et kort-tids fodringsforsøg påvistes at levervægten hos torsk reduceredes signifikant hos rejefodrede torsk sammenlignet med torsk fodret med fed fisk. Proteinindhold i muskel og vægten af renset fisk reduceredes derimod kun ubetydeligt.
