Frogs need water to reproduce. Masses of gelatinous eggs are often found in pond water during spring and summer. In Kansas, the bullfrog is the only common species that has a tadpole stage lasting longer than a year. All others will develop into tiny frogs the same season the eggs are laid. These amphibians are an interesting addition to the aquatic ecosystem, but they usually do not substantially help or hinder the fish community. The adults are quite mobile and often leave the pond. Bullfrogs, however, will take up residence by a pond and can usually be seen sitting on the edge of the water. Frog legs are tasty, and frog harvest during the legal season is another benefit of a pond.

Frogs seldom are a problem because bass and other predators usually keep populations low. Bullfrog tadpoles can become a problem in channel catfish-only ponds or minnow ponds because they can become abundant. Excessive numbers of tadpoles can be reduced by seining, and the adults can be eliminated by capturing them during the legal frogging season.
