Hematology Response of Catfish (Clarias sp.) as an Indicator of Fish Health in Tuban Regency

Abstract

Catfish farming offers strong potential for community economic growth. Catfish are resistant to various water conditions so that many people cultivate this fish. Just like other fish farming, the disease is the biggest obstacle in catfish farming. Changes in fish haematology in response to stress agents are indicators of the stress stage of fish, yielding useful information for curbing unfavourable conditions that can affect fish health. This study aimed to determine the haematological conditions of catfish in three different locations scattered in Tuban Regency as an indicator of fish health. The method used was descriptive by observing Erythrocytes, Leukocytes, Hemoglobin, and Hematocrit at 3 locations, namely in Tegalagung Village (a), Jenggolo Village (b), and Campurejo Village (c). The results of the erythrocyte at all locations were (a) 540,000 cells/mm3, (b) 1,980,000 cells/mm3, and (c) 1,690,000 cells/mm3. The results of the leukocyte count at all locations showed that (a) 301,000 cells/mm3, (b) 545,500 cells/mm3 and (c) 276,000 cells/mm3. Hemoglobin observations showed at the location (a) 16 g%, (b) 10.1 g% and (c) 10.8 g%. Hematocrit observation results showed at locations (a) 14%, (b) 13% and (c) 15%. Based on those results, it shows that catfish are in abnormal conditions. It is concluded that hematological parameters are outside the normal fish limits.
