Features .......
In addition to water, the native catfish can take in oxygen directly from the air due to its extra respiratory tract. So there is no problem to survive in the polluted water of fun and rotten ponds, small ponds etc. Even if the water of the pond dries up, this fish can survive by making small holes. It is possible to market live catfish due to its long survival after being raised from the pond.
Pond construction.....
The size of the pond should be 10 percent to 33 percent and the depth should be 60 to 120 centimeters (3 inches to 4 feet). Inconvenient for greater depth production. Because the catfish always has to come to the top to breathe. This disrupts the fish's growth response due to excess energy loss.
Fry stock..
Healthy and strong fry of 5-6 cm length can be released in the pond at 50 to 60 per sq m. May-June is the best time to release Magur's fry.
Food management...
Magur mainly feeds on the bottom of the water body. These natural foods are non-vegetarian perishable products at the bottom of the reservoir. Animals are plankton and earthworms.
Fertilizer application....
Seven days after application of organic manure, 200 g of urea, 100 g of TSP and 20 g of MPO fertilizer should be applied while maintaining water level up to 60 cm. There is no need to apply inorganic fertilizers when the water color is brownish green, reddish brown, light green, reddish green or green.
Application level.....
At the rate of 5-10% of the total weight of fish stored in the pond, one-fourth of the daily feed should be applied in the morning and the remaining three-fourths in the evening.
