Channel Catfish farming- Best Feeding method for channel catfish for better Yield

channel catfish
Feeding catfish is capital intensive and occupies 75 percent of the total cost of production. The methodology that goes into feeding channel catfish impacts either positively or negatively on its growth rate.
The feeding method, type of feed, stocking and water quality also impact on the food conversion ratio which dictates if a fish farmer is going to make huge profit or loss.
Type of feed
The type of food you feed your catfish is very important for fast growing fish. The feed should have balanced nutrients include28 to 35 percent protein content
You have the option of feeding your fish either floating pellets or a mixture of floating and heavy pellets. Feed them twice daily in the morning and evening and only the amount of food the can handle.
Younger fish like fry and fingerlings require feed with high amount of protein than older fish. Feed manufacturers are aware of this and load feed 0.5 and 1 with more protein.
You can use feed that has lower protein of about 28 to feed your adult fish. Protein is responsible for nitrogen waste in ponds and fish food with lower protein is more beneficial to adult channel fish.
Avoid excess food in the water because it will contaminate and dirty the pond.
Body weight feeding
When you want to do body weight feeding you need to take into consideration water temperature. This method of feed is predicated on knowing the exact collective weight of the fishes in your pond.

Growth and conversion
The good news is that channel catfish food intake decreases while food conversion ratio increases rapidly as the fish grows. Different stages from fry to adulthood have different BW and FCR. The table below clearly shows the different stages and their food conversion ratio.

Stocking your pond
We do not like multi batch production this is when you put both adult and fingerlings in the same pond. Try this and you might lose your entire stock of fingerlings.
This method is possible in a huge natural pond were the small fish has many hiding places. Avoid overstocking and go for accurate stocking or under stocking.
 Adjust your feeding rate to temperature changes by reducing to half at temperature of 60f to 70f. At a lower temperature of 50f the fish farmer is at liberty to feed every other day.
