    Channa punctata: Brief Summary
    provided by wikipedia

    Channa punctata, the spotted snakehead, is a species of snakehead. It is found in the Indian Subcontinent and nerarby areas, ranging across Afghanistan, Pakistan, India, Sri Lanka, Nepal, Bangladesh, Myanmar and Tibet. Its natural habitats are swamps, ponds and brackish water systems. It is a fish of high food value and has little value as aquarium fish.

Comprehensive Description

    Biology
    provided by Fishbase
    Found in ponds, swamps, brackish water (Ref. 6028), ditches and beels (Ref. 1479). Adults prefer stagnant waters in muddy streams (Ref. 4833). Feed on worms, insects and small fish (Ref. 6028). Accept chopped fish and shrimp in the aquarium. Breed throughout the year. Mitochondrial hypertrophy, noted in the double cone of the retina of this species, is considered a basic process in oil droplet formation (Ref. 10557) believed to be an adaptation for enhanced visual contrast detection in turbid waters (Ref. 10407). Used as live bait for angling larger snakeheads.

    Channa punctata, the spotted snakehead, is a species of snakehead. It is found in the Indian Subcontinent and nerarby areas, ranging across Afghanistan, Pakistan, India, Sri Lanka, Nepal, Bangladesh, Myanmar and Tibet.[1] Its natural habitats are swamps, ponds and brackish water systems.[1] It is a fish of high food value and has little value as aquarium fish.

    Description

    Channa punctatus grows 15.0 cm (5.9 in) in length normally, but males with 31.0 cm (12.2 in) also captured.[1] The spotted snakehead is listed as Least Concern in IUCN, due to lack of major threats to life.[2]

    The species is mainly a carnivore. Favorite food of this species is other small fishes and fish larvae. In its natural habitat, it consumes crustaceans, molluscs, insects, small fishes, semi-digested materials and sometimes plants. Its feeding habit changes seasonally. The intensity of feeding is low in mature fishes during the spawning period. Juvenile fish has constant habit of food.[3]

Life Cycle

    Life Cycle
    provided by Fishbase
    Spawning usually takes place at night in shallow water with a silty substrate. 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. 205). The male and female move towards the center of the nest during spawning where the male entwines his body to the female moving upward while releasing the eggs to be fertilised (Ref. 45309). Eggs are guarded by one or both parents. Hatching takes place in a day (Ref. 6028).
