No doubt that some types of waters grow more grass shrimp than others. Type of habitat and predators are the main limiting factors. Note the type of habitat where they were catching them in the u-tube video above linked by Snrub. It would have been helpful if in the video they showed the type of weeds where they were catching grass shrimp.
