Fish pond liners are black flexible impermeable plastics used for holding or retaining water for fish farming. Fish pond liners have now become the best and most affordable way of rearing fish in Kenya. Traditionally, fish farming was done on swampy areas but according to a recent twitter post by Grekkon Limited, fish farming is now practiced on raised wooden structures which have pond lining material installed in them. Common fish raised on fish pond liners include cat fish, mad fish and tilapia. The fish are raised for domestic consumption or for sale.
