How to catch fish with mosquito nets?

I used to cast nets with mosquito nets (that is, tie small stones every other foot under the mosquito nets), but perhaps the mosquito nets were too dense and the descending speed was too slow, and the fish ran away without the nets, so they basically failed; However, it is easy to catch wild small fish by making a frame with thicker wire and wrapping it with mosquito nets to make a ground cage.
