This is where gullible investors fall prey. Before you go into cat fish farming, make sure you know your market or better still make sure you know your buyers and what type of size they buy. For instance it will be difficult for you to get a buyer for a 500g fish if your market environments demands for a 1kg fish and vice versa. However, on average, you should be able to get a size above 1kg within 5 months PROVIDED you fed them well and they are raised with the best and healthy practices
