various canals
Each of us has various canals, rivers, streams, ponds, and large rivers, and in these rivers, seas, or ponds, different types of fish can be found. These fish supply the protein we need.
To collect these fish, we use different methods to catch them. Similarly, here, various types of nets and bamboo have been used to create a suitable method for catching fish.
Through this method, fish will be collected, and these fish will usually be sold in different markets and towns. In addition, they will fulfill the protein needs of each of us.
