Hematological Analysis of Oreochromis niloticus and Clarias sp. Cultivated in Integrated Fish Farming

Abstract

The demand for cultivated fish for public consumption has increased. One of the fish farming methods was a fish pond that is integrated with poultry, especially the types of fish that are easy to cultivate such as tilapia (Oreochromis niloticus) and catfish (Clarias sp.). The aim of this research was to determine the hematological analysis of tilapia and catfish cultivated in the integrated fish farming. The result of the study, physicochemical water parameter showed that the pond has a low pH ± 3,4 and dissolved oxygen ± 2,6 ppm. The tilapia fish had erythrocyte levels of 20,34 x10 cells/mm and leukocyte levels of 189,6x10 cells/mm while the catfish had erythrocyte levels of 29,62x10 cells/mm and leukocyte levels of 113,7x10 cells/mm. Leukocyte and erythrocyte levels in both fish have a different response. The water environment with the integrated fish farming system is shown to have a low pH because of chicken manure and feed residue that entered the fish pond, which is causing the nitrification process and causing the dissolved oxygen to be very low.
