EVALUATION ON HAEMATOLOGICAL DIFFERENCES OF CAT FISH (MYSTUS MONTANUS) IN THREE DIFFERENT PONDS, TIRUNELVELI DISTRICT, TAMIL NADU
The present study was designed to evaluate the haematological parameters of catfish (Mystus montanus) in three different ponds near Tirunelveli District, Tamil Nadu. 30 adult fish of Mystus montanus, 10 fishes from Veinthaan Kulam pond, 10 fishes from Ariya kulam pond, and ten fishes from Nainar Kulam pond were used for the present study. The application of haematological measures is very important in evaluating fish health as it monitors stress and pollutants in the pond. The mean weight and length of fish from the pond were 10±2 g and 12±3 cm. There were no important differences in haematological parameters between the fish in the ponds of Ariyakulam and Veinthaankulam. However, significant differences were observed (P<0.005) in the full blood count, Haematological indications, and differential leukocyte counts of fish in the Nainar kulam pond.
