Abstract
Influence of food of various contents to the growth of carp fry was researched on the fish farm Vukšinac which belongs to »The Fish Farm Siščani«, work organization RIBOKOMBINAT Beograd in the period from May till August 1989.
Experiments were done in four winter fish ponds. Each winter fish pond was stocked with 100 000 carp larve 3 days old. When the body weoght was 0,55 gr. they started to feed them by the same methodology and the same quantity of food but taken from various producers. In two winter fish ponds carp fry was fed by imported Italian food (TROU) and the fish in the others two was fed by the food from our domestic producer from PTUJ made according their own recipe. There were 57,9% proteins in imported food and 40,7% in our own food.
From the results we can see that the fish fry in the same conditions for life and with regular health control fed with the imported food had an average weight about 44,1 g, that is 7,5% from daily growth with food conversion 2,1. The fish fry fed with our own food had an average weight 63,1 g with daily growth of 7,9% and food conversion of 2,2.
