Murrel belongs to Channidae family. They are widely
in tropical Africa (three species) and
Southern Asia predominantly in India, Pakistan,
Afghanistan, Nepal, Sri Lanka, Thailand and China. A
total of 33 species are globally identified, of this 30
belong to Channa genera, and remaining 3 belong to
Parachanna genera. Only 13 species are stated in India.
Murrel is also called as snakehead as it looks like a
snake. Murrel is valued and fetches a higher market
price especially in states like Andhra Pradesh, Karnataka,
Tamil Nadu, West Bengal, Assam, Uttar Pradesh and
Haryana due to its eminent nutrition and medicinal value.
Hardy nature and ability withstand longer time out of
water add greater value to Murrels in the market.
Specialized trade involving live fishes is also practiced in
India.
Murrel is one of the indigenous air breathing fish; there is
a suprabranchial accessory respiratory organ in the
murrel head. Murrels can even survive in lower dissolved
oxygen levels.
The most important aquaculture species of murrel in
India is the striped murrel (Channa striata), the great
snakehead murrel (Channa marulius) and the spotted
snakehead (Channa punctata). The culture technology
standardised only for striped murrel.
BroodstockBroodstock
The brood fish are reared in earthen and cement cistern.
Smaller size pond (0.04 to 0.1 ha) is favoured rather than
larger size pond due to its easy management. The
suggested pond depth is 1.0-1.5 m. Pond dyke should
be made strong enough to prevent fish escape during
the rainy season. The earthen pond is prepared similar to
that of ponds used for culture of the Indian major carp.
The manure (5000 kg/ha/ yr) and the liming (300
kg/ha/yr.) are applied to produce the natural fish food
organisms. A total of 2000 to 2500 kg/ha is stocked and
are fed with low market value fish and rice bran at the
rate of 2-3 percent of body weight.
Typically, two year old striped murrels are used for
breeding. A 100g female is expected to deliver an
average 6000 eggs. The small fish is easy to handle
rather than larger size fish. Inbreeding depression occurs
due to the use of same blood brood fish and it can be
avoided through introduction of brood fishes from
outside source (including rivers, stream, other farmers)
every year. To adapt to the captive condition, 1
brood fish can also be reared in brood tank.
The size of pond and the stocking density depends on
the size of fish and targeted growth of fish. The
supplementary feed is essential at daily two rations at
the rate of 3 - 4 percent of body weight when the
stocking density is higher. Adding aquatic weeds in
about 20% of water area stimulate the natur
environment. Regular examination of maturity, proT
care to brooders, implant hormone pellets and post-
operative care etc need to be taken care of. Total
renlacement of water has to he done at least once in
