Aquaculture producers have experienced significant monetary losses due to the infestation of digenetic
trematodes, often referred to as grubs, in many commercially important food fish species, especially in
yellow perch, bluegill, largemouth bass, hybrid striped bass, channel catfish, as well as others.

There are trematode species that naturally occur in many types of water systems, but there are three species that are most troublesome in commercial fish production ponds.

When completed, this site will consist of an interactive Web site for fish producers to access and obtain information potentially relevant to their snail problems.

Among the various options, information regarding effectiveness, application costs, legal implications, and potential for impact on pond general ecology, e.g.,
zooplankton dynamics in fish fingerling ponds, will be listed.
