Background: Another stage in the Irish Inland Fisheries Trust campaign to eradicate undesirable rough fish in trout lakes and rivers, was recently filmed at Camagh near Ballinamore where a chemical called Botenone was employed.
To remove from Camagh Lake all predatory fish, such as pike, which are keeping the desired trout population low, Rotenone in barrels was taken by boat out on the lake and pumped and sprayed into the water.
Prior to treatment the lake had to be sounded for its greatest depths and its volume of water. An appropriate concentration of the chemical which contracts the capillaries of the gills of fish and thus puts their breathing apparatus out of action, was then piped done to the bottom of the lake and spread over the surface Caged fish placed in various parts of Camagh Lake enabled men to keep a check on the effectiveness of the treatment
The poisoned, or rather suffocated fish rose to the surface - an easy catch for the local people who were standing by, waiting of the results of the lake clearing operation. Rotenone is harmless to human beings, warm-blooded animals and most aquatic invertebrates.
Cleared of its undesirable piscine population Lake Camagh is to be stocked with brown trout - to attract visiting anglora to this district which is already famous for its abundant supply of other species which can be fished with the rod.
