Good evening sir.
My name is D. U. Attah. based in Taraba State, Nigeria. Sir I was
reading an article on fish farming business and I saw your email address.
Actually I wanted to start a fish farming business and wanted to know
more before venture into it. So please sir if you don’t mind, I will want
you to help me with the following information.

Q.3) How many months am I supposed to rear them?
A.3) 3 months if you are targeting 500 – 600 grammes average weight. 5 – 6 months if you are targeting 1.0 – 1.2 kilogrammes average weight.
Q.4) How many KG of feed will they feed on per day (to get a maximum result)?
A.4) It is recommended that you feed the catfish to satiation every time you feed them. The quantity of feed they eat varies with age of catfish, weather and time of day. Generally, the quantity of feed a fish eats varies according to its size. So when they are juveniles they eat relatively little, and when they are 800 – 1000 grammes they eat a lot.
