Effect of Natural Adsorbents Addition into Fish Feed Rations on Water Parameters

In this research, the effects of zeolite, leonardite, and diatomite, added into fish feed of 40% protein value in different amounts, on water parameters were investigated. The experiment consisted of 10 groups with three replications (control (C), 2 % zeolite (Z2), 4 % zeolite (Z4), 8 % zeolite (Z8), 2 % leonardite (L2), 4 % leonardite (L4), 8 % leonardite (L8) 2 % diatomite (D2), 4 % diatomite (D4), and 8 % diatomite (D8)). In the study, feed containing 40 % crude protein was used to be within this protein value range. When the experimental groups in the study were examined individually, it was determined that similar to the results in the zeolite groups and leonardite groups, there was a decrease in the ammonia and TAN values in the water as the amount of adsorbent in the feed increased. When these results are evaluated, it is thought that the addition of adsorbent in greater amounts (e.g.,>8 %) than the amounts in this study could be significantly more effective.
