Traders in the 13th Century that traveled to Kublai Khan's China brought this design of fishing net to India. A large net, with stone counterweights are used for fishing in Kerala State, in India. Here are a few shots of these nets. I don't recall seeing this design being used by Chinese fishermen.

I'm not 100% happy with these shots; I only have my little Panasonic GX7 along and my post-processing tools are somewhat limited.
