Classification. Abstracts The paper deals with the incidence of abnormality observed in a common fresh water fish, Channa punctatus belonging to the family Channidae from a pond in the vicinity of the first author's residence. The values are the mean along with standard deviation for each group (n = 3).Comparisons were carried out by Students t test. were isolated from infected Channa punctatus and physico-chemical properties were analyzed from various ponds. Healthy fresh water teleosts, Channa punctatus (average length 11 ± 2 cm and weight 23 ± 2 g) were obtained from fish market and treated with potassium permanganate (PubChem CID: 516875) solution (0.5% w/v) for 1 min to remove any dermal adherent. Dendritic cells have been characterized morphologically and functionally in the teleost fish models such as rainbow trout, salmonids, medaka, and zebrafish. Channa punctatus is the common predatory fish which have low food value and due to predatory nature, they engulf the fingerlings of cultured carp at several stages of their rearing [1] and thus adversely effect the cultured carp production and put a great loss to the fish farmer. The reduction in MCHC has also been observed in Channa punctatus6. Ammonium sulfate induced nuclear changes in the oocyte of the fish, Channa punctatus (Bi.). In the present study efforts have been made to find the antimicrobial effect of the mucus of two bottom dwelling fresh water fishes namely, Channa punctatus and Cirrhinus mrigala. Company: Channa stewartii (Golden Snakehead) should not be kept with fish smaller than 2/3 of the species size. This fish is available in almost all over the country. Organophosphate pesticides are increasingly used in recent years due to their biodegradability and short resistance time in the environment. Cite this article. Channa punctatus (Bloch.). After that, healthy fish (male and female) weighing approximately 35± 5 g were transferred to glass aquarium with 50 L capacity in controlled light (12 hr light/12 hr dark) and aeration conditions.
