How to catch river shrimp and what is the best to eat?

The simplest tool for catching shrimp is the "flower basket" net, which is a small net with the diameter of a washbasin. The net bag should not be too deep, just use gauze. 10 cm is deep enough. Tie the "flower basket" net with a rope and put it into the water. Tie a piece of foam plastic to the upper end of the rope and let it float on the water, so as to find the net rope when pulling the net. Note: put some fresh sheep bones in the net bag. Sheep bone and net bag are fixed with thread to avoid falling into the water. Every once in a while, I slowly lift the "flower basket" and see several big green shrimps in the net bag. . . Unless there is river shrimp in the water. You can make more baskets and cycle up and down.

If there are no sheep bones, chicken intestines and pig blood will do.
