Kondisi Darah ikan toman (Channa micropeltes) di Perairan Sungai Siak dan Sungai Kampar Provinsi Riau Blood condition of Channa micropeltes from the Kampar and Siak Rivers, Riau Province

Abstract

Siak River is one of the most polluted rivers in Riau and its low water quality may negatively affects the health status of fish that inhabit that river. The Kampar River in contrast, is in good condition. To understand blood condition of C. micropeltes living in both rivers, this study was conducted. Totally 6 fishes from Siak and 6 fishes from Kampar were studied. Blood was obtained from vena caudalis and then was checked using a binocular microscope for erythrocyte and leukocyte number. Haematocrite and leucocrite levels and type of leukocyte were also studied. Results shown that blood condition of fish taken from both sampling sites were different. The erythrocyte of the fish from the Siak River was 1,786,667 cells / ml and that of the Kampar River was 2,306,667 cells / ml. While the number of the leukocytes of the Siak’s fish was 196,167 cells / ml and that of the Kampar’s fish was 227,250 cells / ml. There were 4 types of white blood cells in C. micropeltes, namely lymphocytes, basophiles, neutrophils and monocytes. The thrombocyte, however, was not be found. The water quality of both sampling sites were rather different, but their general condition is fair and able to support the life of the C. micropeltes
