On the river flowing through dense forest, select a quiet corner and close it in order to reduce the water inflow
From the forest, bring branches of the tree ‘kaai mara’ and pound its poisonous leaves into a paste
Take the paste of the crushed leaves, throw it in the river and disperse the intoxicating material into the water. The fish will become dizzy and somnolent
Fix a net on the border
Wait for the poison to make its effect
The fishes become dizzy and somnolent. Some get entangled into the net. Pick it up
Other sleepy fishes hide under the rock. Find them and catch them
Some fishes come floating on the surface. Try to catch them ! ... more or less easily...
