Long handled net - I use 10' and bag mesh anything up to 1/8" or 1/4". Larger the size mesh, quicker you can run - but you may lose some shrimp. I use several different bags, anything from 1/16 - 1/4" through the vegetation. Should work fine for you.

Also, umbrella or cast nets can work, too. Mesh size very important for both these.

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
