Mud minnows/ Matagorda

First trip there is in October. Can anyone tell me where to trap or net mud minnows? We’re staying on the river. Also will be surf fishing.

I catch storm/cocahoe/bull minnow with cages usually near moving shallow water. Check ditches near the roadway as they will sometimes hold minnows. You should see them swimming before you set up the cage in the spot you chose. I find cracked crabs work well to catch them.
