The purpose of our researches was to develop a cheap feed recipe for improving the bio-productive indices of juvenile phytophagous fishes. The experiments were performed on a total of 160 larvae of grass carp(Ctenopharyngodon idella), divided into 3 groups: one control and two experimental groups. The ration of juvenile
grass carp from the control group consisted of: yeast autolysate, fish meal, wheat flour, milk powder, methionine and vitamin-mineral premix. In the experimental rations, wheat flour was replaced by grape marc meal and yeast autolysate– by dry wine yeast. In addition, the immunostimulatory bio-product b - glucans extracted from cell walls of Saccharomyces cerevisiae was administered. The results showed that the introduction of the mentioned components to the feed provides the organism of larvae of phytophagous fishes with easily assimilated protein and carbohydrate substances, thus stimulating the metabolic processes and increasing the overall ichthyo-mass. The use of the given
feed recipe leads to an increase of 22.0-26.7% of the survival rate, 16.9-24.0% of the average larvae weight, 45.2-56.3% of the average general ichthyo-mass, compared to the control group. The stimulating effect was achieved when administering the feed 5-10 days after hatching, during a period of 20 days. Depending on the age, the feed is administered every 3-4 hours according to the ratio of 75-50% of feed per mass unit of larvae. |
