Some of the methods of catching fish at Cochin are thus described by Dr. Francis Day. [99] "Cast nets are employed from the shore, by a number of fishermen, who station themselves either in the early morning or in the afternoon, along the coast from 50 to 100 yards apart. They keep a careful watch on the water, and, on perceiving a fish rise sufficiently near the land, rush down and attempt to throw their nets over it. This is not done as in Europe by twisting the net round and round the head until it has acquired the necessary impetus, and then throwing it; but by the person twirling himself and the net round and round at the same time, and then casting it. He not infrequently gets knocked over by a wave. When fish are caught, they are buried in the sand, to prevent their tainting. In the wide inland rivers, fishermen employ cast nets in the following manner. Each man is in a boat, which is propelled by a boy with a bamboo. The fisherman has a cast net, and a small empty cocoanut shell. This last he throws into the river, about twenty yards before the boat, and it comes down with a splash, said to be done to scare away the crocodiles. As the boat approaches the place where the cocoanut shell was thrown, the man casts his net around the spot. This method is only for obtaining small fish, and as many as fifteen boats at a time are to be seen thus employed in one place, one following the other in rapid succession, some trying the centre, others the sides of the river. "Double rows of long bamboos, firmly fixed in the mud, are placed at intervals across the backwater, and on these nets are fixed at the flood tide, so that fish which have entered are unable to return to the sea. Numbers of very large ones are occasionally captured in this way. A species of Chinese nets is also used along the river's banks. They are about 16 feet square, suspended by bamboos from each corner, and let down like buckets into the water, and then after a few minutes drawn up again. A piece of string, to which are attached portions of the white leaves of the cocoanut tree, is tied at short intervals along the ebb side of the net, which effectually prevents fish from going that way. A plan somewhat analogous is employed on a small scale for catching crabs. A net three feet square is supported at the four corners by two pieces of stick fastened crosswise. From the centre of these sticks where they cross is a string to pull it up by or let it down, and a piece of meat is tied to the middle of the net inside. This is let down from a wharf, left under water for a few minutes, and then pulled up. Crabs coming to feed are thus caught.
