Bombay. Indian Journal of Geo-Marine Sciences Vol. Habit and Habitat of Channa Punctatus: The lata fish inhabits fresh-water ponds and ditches. The reduction in MCHC has also been observed in Channa punctatus6. The testes are two in number and are elongated structures. According the Bhuiyan (1964), maximum length is 30 cm whereas Rahman (1989) reported this fish attains over 240 mm in total length. It is concluded that Channa punctatus and Clarias batrachus are stenothermal. Any change in the aquatic environment causes altered behavioural responses, ultimately leading to physiological adjustments. Proximate composition (moisture, protein, fat and ash) and chemical analysis (pH) of fresh and dry-salted (DS) fish samplesShoal (C. striatus) and Taki (C. punctatus) were determined using standard methods of analysis at room temperature (27 0 31 0 C) for shelf life study. Before publishing your Notes on this site, please read the following pages: 1. These fishes are known as “Zeol fish” (Shafi and Quddus 1982). The striped snakehead (Channa striata Bloch, 1793) is a commercially important freshwater fish, found in a variety of habitats, encompassing swamp, rivers, streams, and a lake in southeast Asia, middle east and Africa 1. Description of the species: Length of head is 3.2-3.5 of total length and 2.7 of standard length (Rahman, 1989). Freshwater Fishes of Bangladesh. 2009b. Sci. Seasonal variation in helminth parasites of snakeheads Channa punctatus and Channa striatus (Perciformes: Channidae) in Uttar Pradesh, India. In treated groups of cadmium exposed fish have been found to significantly decreased in total erythrocyte count, haemoglobin conte … Channa punctatuss () were treated with Being non-biodegradable concern regarding its toxicity has risen. The maximum rise of 18.93% (80.74 ± 78.56) in serum cholesterol was observed after exposure of 96 hrs at 0.40mg/l Sumithion pesticide. Calculated the LC 50 value of Lead nitrate in the fresh water air breathing fish, Channa punctatus. The ability to breathe in air by its accessory respiratory organ helps the fish to thrive well out of water for a considerable period of time.

Specimens of Channa punctatus were collected from the local fish market.Fish were acclimatized in the laboratory for a period of two weeks. thetrichodinidparasitesin C.punctatus withdi erenthabitat ofvaryingwaterqualityinSylhet.e majorobjectivesofthe present study were to observe the trichodinid parasites on the gills of C. punctatus from the wild and cultured ecosys-tems and to nd out the prevalence and mean intensity of infestationof trichodinidparasites in Channa punctatus . Eyes comparatively of small size and located on the anterior of head. Eggs are laid in nests through elaborate tunnels in vegetated areas which look like vertical columns of water with the eggs floating in the center (Ref. Effect of hexavalent chromium J Ecophysiol Occup Health 7:171–175. ), in Channa punctatus. Tilak K.S. Scanning Electron microscopy of hooks and spines of male and female worms, exhibit sexual dimorphism. Scanning Electron microscopy of hooks and spines of male and female worms, exhibit sexual dimorphism. Channa punctatus (Bloch) exposed to the toxicity of cypermethrin Jaya K. and Shettu N. P G and Research Department of Zoology, Pachaiyappa’s College, Chennai _____ ABSTRACT In the present study, an attempt has been made to examine the toxic effect of cypermethrin, a synthetic pyrethroid exposed to freshwater fish Channa punctatus. Reproductive System of Channa Punctatus. Result: There was significant increase in serum cholesterol in Sumithion pesticide exposed, fish Channa Punctatus, comparative to normal control subject. The spotted snakehead, Channa punctatus (Bloch) belonging to the family Channidae. Geographical Distribution of Channa Punctatus 3. Welcome to NotesOnZoology.com! Males weighing 10 ± 2g and females weighing 12 ± 2g were divided into groups of ten each and were exposed to different concentrations of deltamethrin ranging from 0.02 ppm to 0.2 ppm, for five exposure periods, i.e., 1, 7, 15, 20 and 30 days. Biology, Channa Punctatus, Chordate Classification, Phylum Chordata, Zoology. Sexes are separate. Fische. Channa punctatus is infected with a new species of acanthocephalan parasite, P. punctati n. sp. Stomach is an elongated sac-like structure. Teeth on lower jaw are conical. On the ventral surface many minute apertures called nephrostomes are present. Two ureters from the two kidneys unite at the posterior end to form a common ureter which communicates with the urinary bladder. The parameter including total count of red blood corpuscles (RBC) was studied in details and showed highly sensitive Several ecotoxicological characteristics of Channa punctatus, such as wide distribution in the freshwater environment, noninvasive, availability throughout the seasons, presence of 32 well-differentiated diploid chromosome numbers, acclimatization to laboratory conditions, make this According to Bhatti (1934), C. panctatus burrows in mud and prefers stagnant and muddy to running waters. Ophicephalus punctatus Bhuiyan, 1964, Fishes of Dacca. Channa punctatus) and its pickled product.
