MultispeciesTamer;3645542; said:not cost effective but effective in getting rid of the pest fish. Most other ways which stun the fish are not reliable. To stun a large area such as a pond there only ment for basic assesments of what species are present not for large scale use or eradication of one species. With electroshocking which stuns fish and they float to the surface there is no way to make sure you get all of the pest fish.
I see thanks.
