Commercial catla fish farming business is gaining popularity day by day. Because catla fish is one of the very popular freshwater fish species which is raised throughout India, Bangladesh and some other South Asian countries.
Pond Size and Construction
After selecting a good site, you have to make a pond for starting catla fish farming. The size of the pond can be any depending on your available land. But a pond measuring around 1 acre will be very good for commercial catla fish farming business. And natural or earthen ponds are considered good for commercial fish farming business.
After making the pond, you have to prepare it for growing the fish to their full size. For preparing the pond, you have to apply both organic and inorganic fertilizers into it along with providing with supplementary feeds daily. The application dosage of organic and inorganic fertilizers depends on the farmingintensity and inherent productivity. You should contact your nearest aquacultureor fisheries institute for more information.Collect seed from any of your nearest catla fish breeding centers. Catla fish breeding is very common and induced breeding is playing a major role for entire seed requirement in all the countries where catla fish is available. By the way, you should collect the seeds from any of your nearest hatcheries. You can contact your nearest agriculture extension office or any fisheries institute for having information about available catla fish breeding hatcheries in your area.
Rearing the Fingerlings
As we have mentioned above, you should not stock only catla fish in your pond. Rather, catla should be reared along with Mrigal and Rui. For raising the fry in nursery pond, you can stock up to 0.1 to 0.2 million fry per acre pond. Generally, 2.5 cm fry are raised in the nursery pond, and then you have to raise the fry until they reach around 10 cm length. And finally you can stock them to the main pond.
Feeding the Fish
Providing supplementary feeds is very important for commercial catla fish farming. Without providing adequate supplementary feeds, you can’t expect good growth of the fish. Catla fish generally consume food from the upper level of water. They are natural food lovers and generally eat whatever insects of small plants float on the surface of the water.
But in case of commercial catla fish farming, you have to feed the fish with supplementary feeds. Generally, most of the farmers use ready-made commercial feeds for feeding their fish. Total amount of feeds depend on the number of fish stocked in the pond. But the general rule is that ‘you have to feed the fish with 5% food daily of their total body weight’.
For example if you have stocked 10,000 fish and each fish weights 20 grams then you have to provide 10,000 grams (10,000×20/100×5) of food daily. And also consider the mortality rate while determining total amount of food. And it’s recommended to feed the catla fish multiple times in a day rather than all at once.
