Effect of starvation on nutritive value of carp (Cyprinus carpio L.) and selected biochemical components of its blood

Abstract

The experiment, carried out in the aquarium room of the Faculty of Marine Fisheries and Food Technology, involved 72 carp juveniles. The fish were kept in 6 aquaria for 12 weeks without food. Levels of crude protein, AspAT and AlAT activities, levels of glucose, triacylglycerols, cholesterol and its fractions as well as body weight reduction and body composition were analysed. Starvation was found to significantly affect the crude protein level and AspAT activity as well as the blood levels of glucose, triacylglycerols, cholesterol and its fraction and the body chemical composition. The significant changes occurred both in relation to the initial status of the fish and between successive stages of the experiment.
