THE INFLUENCE OF THE FOOD TYPE ON THE DEVELOPMENT OF PIKE-PERCH (Sander lucioperca, Linneaus -1758) IN THE POST-EMBRYONIC PERIOD

The culture of the pike-perch(Sander lucioperca, L.-1758), in intensive aquaculture, is difficult to achieve due to its character as an active predator in the water mass. In recent years, significant quantities of pike-perch are requested by consumers, being more and more numerous those who prefer this species. Choosing the most appropriate food category is very important, because it can make the difference between the success or failure of development in the post-embryonic development stage. The experimental works for the development of the pike-perchtook place in three variants, with different food being administered, as follows: variant 1 - zooplankton (Daphnia sp.) was administered, variant 2 - prussian carp larvae (Carrassius gibelio) were administered and variant 3 - granulated feed was administered.The growth was carried out in "Evos" fiberglass tanks. The results obtained were very good in variant 2. Good results were also obtained in the other two variants (variant 1 and variant 3). The decision of the way of post-embryonic development remains at the farmer's choice..
