In India, the practice of rearing freshwater fish has increased rapidly in the last few years . The biggest reason for this is that in this business, the cost to the farmers is low, while the profit is high. Also, nowadays the demand for fish meat is also high in the market. In such a situation, this business is booming in villages, towns and cities. If you want to earn good profit by doing business of freshwater fisheries, then mixed species fish farming should be done. This results in higher profits and less cost to the farmers.
The biggest problem during fish farming is the proper distribution of food items. Many times, either all the fish are not getting enough food or the food is wasted due to adding more food items than required. In such a situation, for proper utilization of food in the pond, mixed rearing of Katla, Rohu and Mrigal species should be done in the native species. Actually, these three species do not compete for food. The biggest reason for this is that where the Catla fish eats the food of the surface, Rohu middle and the bottom of Mrigal pond.
Unlike the Catla, Rohu and Mrigal species, the silver carp, grass carp and common carp do not compete for food in the exotic species. Like Catla, Silver Carp feeds on the water surface, like Rohu Grass Carp and like Mrigal, Common Carp feeds on the surface of the pond.
Fisheries experts suggest that these 6 species can be reared together to earn more profit, which results in lower cost and higher profits. For this Catla, Silver Carp, Rohu, Cross Carp, Mrigal and Common Carp should be stored in 20:20:20:15:15:15.
Before storing fish seed in the pond, fill a polythene packet with water and oxygen. After this keep this packet in the pond. During this, introduce pond water in the packet, this prepares the environment for equilibration. After this, fish seed should be removed slowly in the pond .
After harvesting the seeds of fish in the pond, if the food in the pond is less, then 1800 to 2700 kg per hectare of rice bran or mustard or groundnut cake should be applied annually. For proper utilization of food, fish should be given food at a certain time. Due to this the diet does not go in vain. For this, the food item is filled in sacks and hung with the help of sticks. At the same time, small holes should be made in this sack. Keep in mind that some part of the sack should be above and most of the part should be submerged in the pond.
After 12 to 18 months, when the fishes become 1 to 1.5 kg, then the fish should be removed. Which can be sold at wholesale price from Rs 50 to 80 per kg and in Kherchi from Rs 140 to 200 per kg. Explain that in mixed fisheries, the expenditure of 18 to 30 thousand rupees is incurred in the first year. At the same time, about 3000 kg of fish can be produced in a year. In this way a profit of about 2 to 2.5 lakh rupees can be taken annually.
