The influence of natural zeolite was analyzed, as a feed additive applied in a concentration of 0.8% on morphometrical characteristics and basic production index of rainbow trout (Oncorhynchus mykiss) breeding. By analyzing the obtained results it is found that the presence of zeolite in the trout feed has a positive effect with a statistical significance (p is less than 0.05) on all analyzed morphometrical indexes of the fish growth rate, on their final body weight, total body length, body length and height, as well as their growth. Including zeolite in the trout mixture had a stimulative effect on the acomplished results of the basic production index of the condition factor (CF), the coefficient of total growth (CTG) and production index (PI) in comparison with the Co-group of fish that are fed without adding zeolite to feed.
