A fast growing fish species is capable of reaching marketable size or weight in 4-6 months (depending on desired consumer weight) under pond condition. By this age,tilapia may weigh 100-250g and catfish about 200-500g. In practice,the size of fish in the pond is sampled from time to time using scoop–net. When desired weight or size is achieved,a drag–net is drawn through the pond water.
Before a fixed harvest date, aggressive advertisement should be embarked upon to sensitise and secure buyer in advance. Also, due to the recent demand for fish marketing fish is not much a problem as Nigerians now demand for high nutritive and proteinous food which fish belongs.
To maximise profit, efforts should be made to keep harvested fish alive,since live fish usually attract the best price compared to frozen and smoked fish.
Dead and live fish that cannot be sold immediately,or that have to be transported to distant markets,must be promptly and properly preserved to avoid spoilage.
Refrigerated van, cold room, freezer,iceblock and refrigerator can be used
Smoking over wood or charcoal fire is the traditional method conventionally used to preserve fish. Salting and canning can also be adopted.
