Fish pond liners

Admin - August 21, 2022 - 0 comments

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.

Qualities of good fish pond liner materials

  • Good fish pond iners must be UV treated to increase longevity. Quality fish pond liners can last between 10-30 years depending on the thickness and gauge.
  • They should be made from virgin materials, not recycled. Recycled dam liners have very short lifespan and tend to crack within 1 year.
  • The materials should be highly resistant to abrasion and puncturing.
  • They should be available in a wide variety as HDPE, PVC and LLDPE.
  • They should be easy to install

What to look for when purchasing fish pond liners

Before purchasing dam liners, always consider, type of material, thickness, size of the dam among other features. It is advisable to get the right dimensions of the dam before purchasing the liner.


Fish dam liners can be installed in wooden structures or on excavated land.  For wooden structures, they are raised 1m above the ground and 1m below ground for excavated ponds. The length and width will depend on the number of fingerlings to be reared.
