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 We illustrate the expected staining characteristics of control Channa punctatus liver tissue with Methyl Green -Pyronin â??Yâ?? chemical alterations in air-breathing fish, Channa punctatus. water fish, Channa punctatus Shahida Parveen, Ram Bharose and Dharam Singh Abstract Channa punctatus is the most common fish found in Indian rivers and water bodies. When fishes were exposed to NaAsO 2, it induced death of the fishes in a concentration-dependent manner. Bombay. Our mission is to provide an online platform to help students to discuss anything and everything about Zoology. Each kidney is composed of numerous uriniferous tubules. p.124. Reproductive System. Channa punctatuss () were treated with Bhatti, 1934. Channa punctatus. Lata fish is notable for migration over­land from one pond to another during rains. Length of head is 3.2-3.5 of total length and 2.7 of standard length (Rahman, 1989). 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. The caudal fin is unilobed. 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. Mouth is bounded by upper and lower jaws. Less catch in river or running water but good catch in flood plains, beels etc. Abidi R, Srivastava U. Journal of Royal Asiatic Society of Bengal Science. This is the first record of Pallisentis from Bareilly, Uttar Pradesh, India. Any change in the aquatic environment causes altered behavioural responses, ultimately leading to physiological adjustments. Two trichodinid parasites, Trichodina cyprinocola and Trichodina pediculus , were acknowledged in the gills during a sampling preparation of thirty fish Channa punctatus from the wild and cultured environments. Channa punctatus is commonly known as snake head fish of carnivore feeding habit. The count in fish Channa Punctatus exposed under organophosphate pesticide sumithion. India has 9 species of Channain different part of India. Sexes are separate. Ausland.Fische. External nare is on the top of the head. 2.2 Researching procedure . Before publishing your Notes on this site, please read the following pages: 1. Lower jaw is slightly protruding. The present work was undertaken to point out the inter-relationship of various hematological parameters due to acclimation at cold and warm temperatures in Channa punctatus (Bloch). The body is divided into head, trunk and tail regions. In the present study a non-significant to very highly significant reduction in MCHC from 26.62% has been observed (Table-1). It is usually carnivorous and eats other small fishes and small aquatic ani­mals. p.95. Both the scales are systematically arranged cycloid and prectenoid. Proceeding of the National Academy of Sciences. Channa punctatus. Habit and Habitat of Channa Punctatus: The lata fish inhabits fresh-water ponds and ditches. 1933. Generally spiracle is absent in Actinopterygii. 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. Learn how your comment data is processed. Being non-biodegradable concern regarding its toxicity has risen. Any change in the aquatic environment causes altered behavioural responses, ultimately leading to physiological adjustments. Biology, Channa Punctatus, Chordate Classification, Phylum Chordata, Zoology. exposure on the pituitary-interrenal axis of a teleost, Channa Silfer EH, King RL. According to Bhatti (1934), C. panctatus burrows in mud and prefers stagnant and muddy to running waters. p.123. The fish species Channa punctatus was selected for the test because of some ecotoxicological characteristics such as wide distribution in the freshwater environment, non-invasive, availability throughout the season and easy acclimation to laboratory conditions (Kumar et al., 2010). ?s Reaction stains. The present work was undertaken to point out the inter-relationship of various hematological parameters due to acclimation at cold and warm temperatures in Channa punctatus (Bloch). Fresh water fish, Channa punctatus, was exposed to PND in aquaria wherein its LC50 value was recorded to be 3.6 mg/L. Channa punctatus to chronic toxicity of tannery effluent is ed in Figures 1-3. Wepener V, Van Vuren J, Du Preez H. Effect of manganese and iron at a neutral and acidic pH on the hematology of the banded tilapia (Tilapia sparrmanii). fjs.parentNode.insertBefore(js, fjs); 6;  A. Barbells are absent. ADVERTISEMENTS: 3. 100 ppm, the highest concentration tested in this study, was found to be the deadliest and it induced death of the fishes within 18 to 20 h. As the concentration lowered the survival time increased dose dependently. 20-22. If YES, Please SHARE with your friends Endosulfan not only changes the physico-chemical characteristics of water but also impose drastic impact on the fish. 28°35' N, Long. The cypermethrin pesticide is widely used in agricultural field for the control of insect pests and is coming under synthetic pyrethroids which have shown strong pesticidal activity in freshwater teleost fish, Channa punctatus. Effect of endosulfan on certain aspects of hematology of the fish, Channa punctatus (Bloch). 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. chemical characteristics, such as temperature, pH, TDS (total dissolved solids), DO (dissolved oxygen), hardness, alkalinity, chloride and iron of experimental water were recorded throughout the experimental period. The fishes were exposed to sub lethal It is voracious and predatory to small fish and fries. Lata fish is notable for migration over­land from one pond to another during rains. This fish has great economic importance because it is eaten as food. Materials and Methods: This research study has been done in fish Channa Punctatus, which was exposed 24 to 96 hours to four different concentration of sumithion pesticide. Channa striata are locally known as ikan gabus, belonging to the family Channidae 2, which prey on fish, crustacean, and gastropod 3. 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 . These are commercially important fishes in our country and comparatively cheap too. Scales are large and on head irregular. SEM studies showed species-specific attachment organs.
