Disposal method for low valuable species of lake fishes

摘要

The method of disposal of undersized species of lake fish is characterised by the fact that the undersized species of lake ichthyfauna caught and the undersized fish are compulsorily composted with organic structural materials of up to 20 to 30% dry weight of fish in such a way that organic material is stored first, then organic material mixed with fish,then it covers itself with organic material and retains the compost mass to equalise its temperature from the ambient temperature in a constant humidity from 60% to 70%. The whole of the compost mass is spread with brown-coloured gravel, ranging from 0,5% to 1,5% dry mass of composted materials. Organic structural materials are a straw or sawdust or bark.
