Özet
This study was performed to evaluate the effects of adding different levels of natural zeolite (clinoptilolite) to juvenilerainbow trout (Onchorynchus mykiss) diets about growth performance and some biochemical blood parameters. Theexperimental system was designed as a semi-recirculating aquaculture system and 20 rainbow trouts which weigh 7.91±0.03g distributed randomly for each tank (300 L). Fish were fed to apparent satiation with diets containing 45% crude protein and14% crude fat for 70 days which included no zeolite (Control), 0.5% zeolite (Z05), 1% zeolite (Z1), 2.5% zeolite (Z25) intriplicate. Finally, blood samples were collected from all fish tanks to analyze some biochemical blood parameters likecholesterol, triglycerides, LDL, HDL, and VLDL. At the end of the experiment, Z25 group showed negative results in finalbody weight, weight gain, and specific growth rate (p<0.05). Although Z05 group showed no significant difference, itshowed the best results in final body weight, weight gain, specific growth rate, feed intake, feed conversion rate, and proteinefficiency. In terms of blood parameters, all the groups had similar values with no significance (p>0.05) compared to thecontrol group. As a result, there was a tendency towards decreased growth and feed utilization due to the addition of zeolitehigher than 1% in diets. It could be concluded that limited usage of clinoptilolite in rainbow trout diets might have beneficialeffects on growth parameters.
