Fish in the Reservoirs

All the fish growing in the reservoirs are freshwater fish with an average life-span of three to seven years. The commonly observed types include Silver Carp, Big Head, Tilapia, Mud Carp, Edible Goldfish, Wild Carp, etc.

As Silver Carp and Big Head are river fish which require a high flow of water in spring to induce spawning and cannot reproduce in the still water of impounding reservoirs, fish fry are regularly stocked into the reservoirs to maintain a favourable ecological balance. Silver Carp which fed on phytoplanktons are particularly effective in controlling algal proliferation. Different from Silver Carp and Big Head, Tilapia can be found in various reservoirs by natural growth and reproduction.
