Hello everyone, in todays #celestialchallenge initiated by 
Am so happy to guide you on how to start up your own fish pond, ..fish business in Nigeria and in the world at large is one of the most fast growing business anyone can venture into either in small or large scale, because it has increasing demand and little supplier.

Fish has been an important source of protein and other nutrients and minerals for humans. Fishes contain omega-3 fatty acids, and are heart-friendly and can make improvements in brain development and reproduction.

My fish pond can accommodate up to 500 grown fishes/each pond, it takes up to 3month for a small fish to reach maturity.

Fish unlike another farm animals require proper feeding to prevent them from eating each others (a mature fish can eat a small fish). When building your pond ensure you build a big one with lot of space to allow free movement of the fish. Separate grown fish from the pond of the small one's to avoid them from eating each other up.
Before starting a fish pond ensure you have full access to water supply, as water is the primary source of their survival... The fish pond is excepted to be clean 1 or 2 time's in every month.
Channel the dirty water to a well or gutter to prevent hazard, and ensure the pond is clean.
