Spent 30 minutes collecting along shore (1-4 feet deep) sweeping net quickly across marsh bottom and through vegetation. Used D-net with 1/4 inch mesh approx. 14 inches wide and 10 inches tall with 5 foot long handle. Collected no fishes. 95% of catch was what appeared to be one species of Lymnaeidae snail and a few aquatic insects (2 Zygoptera, 1 Anisoptera, 1 Dytiscoidea).
