Gourami is a
fish not popular in many people, maybe because it is almost a bony fish with
little flesh on it. But it has taste acceptable to some especially if it is
fried.
Crossbreed
gourami was much bigger and tastier compared to native breed. They are being
cultured commercially. The native species were found in rivers and streams.
The cultured
gourami is bigger in size and can reach over 2 kilograms. It has not been
raised in many fish farms because it grow so slow not suitable for commercial
production. The slower they grow the bigger the cost of raising them.
The only
benefit is that it can easily adapt to any kind of environment. They can be
raised even in rice field as long as there is enough water to live with. They
grow in man-made pond even in tanks.
In raising
gourami in pond, it should have higher dike level to protect them from getting
away. A pond of 5 meters wide will do with recommended deepness to store water.
It should have water source ready in case the water level of the pond reduces
to the required height. It is better if the man-made pond is near the river
easy to irrigate the pond if the need arises.
To aid the
fish of their food requirements, the pond can be planted with floating weeds.
The best plants are water lily or water hyacinth that will invite flying
insects. Other insects and tiny organisms are favorite foods of the fish.
A pair of
male and female gourami with the size of 160 grams is enough to be breeder in
the small breeding tank. One breeder can raise many thousands of fingerling
(fry). The fry are then transferred to rearing pond until they are ready for
harvest if the size reaches 100 grams. The duration of rearing time is about 7
months.
Gourami fry
are feed on small plants and plankton found in the water. Regularly, the fry or
adults are feed with fish meal and other food residue.
In order to
raise many organisms in the pond, the application of organic fertilizer (animal
manure) will create activities in the pond. In addition to giving them
supplemental feeding (rice bran), it can support thousands population of
gourami fry until adulthood. The rate of application is 16 kilos of organic
fertilizer per hectare per day for 2 months.
A one
hectare pond is ideal for commercial production to be able to have better
harvest in marketable size of adult gourami.
It is a must
that the fry are raised separately from the breeder to avoid cannibalism of its
own kind. The survival rate of the fry will depend on how the fishpond owners
make the necessary control against many kinds of predators around the pond
especially during the early days of their growth.
