    Blood condition of Clarias batracus from the Kampar and Siak Rivers, Riau Province
    (2013-01-14) Anggun Satrisno, Panji
    Siak River is one of the most polluted river in Riau and its low water quality may negatively affects the healt status of fish that inhabit that river. The Kampar River in contrast, is in good condition. To understand blood condition of C. batracus living in both rivers, this study was conducted. Totally 6 fishes from Siak and 8 fishes from Kampar were studied. Blood was obtained from vena caudalis and then was checked for the number of erytrocyte and leukocyte numbers, hematocrite and leucocrite levels and type of leuklocyte was studied. Leukocyte type was studied by smearing blood in the slide glass and stained with Giemsa. Results shown that the condition of blood of fish from both study sites was not signigicantly different. The number of eritrocyte and leucocyte of fish from the Siak River was 2,775,833 (hematocrite level 25.93%) and 276,750. (leukocrite level 29.72%)., while those of the Kampar River was 2,031,250 and 130,813. Types of leukocyte present in fish from both sampling areas also similar, there are monosit, limfosit, trombosit, and netrofil.

    Histological structure gill and of the Kidney Kryptopterus limpok at Kampar River and An River Siak Riau Province
    (2012-11-26) Hidayat
    Siak River is one of the rivers that has polluted water in Riau. Low water quality in this river is negatively affects the fish living there. To understand other effects of low quality water on fish, a study aims to understand the histological structure of organs of Kryptopterus limpok has been conducted. Fish organs (gill and kidney) were processed for histological studied (formalin fixed, alcohol series, HE stained, 6 sliced). The structure of the organs were compared with the organ of fish captured in the Kampar River that has good water quality. Results shown that in general, histological structure of gill and kidney structure of fish from both areas are different. The cell structure of the Siak’s fish shown abnormality, while those of the Kampar fish were normal. Cell abnormality such as hyperplasia, hypertrophy, necrosis, hemorrhage, epithelium lifting and fused lamella are present in the gill of Siak’s fish. Most of lamella fused and there was no space between lamellae. In the kidney of the Siak’s fish, there were damaged glomerulus cells, hemorrhage, kongesti and mineralization. Based on data obtained, it can be concluded that low quality of water in the Siak river causes abnormality in tissue structure of the fish.
