THE EFFECT OF THREE DIGENETIC TREMATODES ON CULTURED FISH IN THE SOUTHERN UNITED STATES.. SOUTHERN CONFERENCE OF RESEARCHERS IN AQUATIC DISEASES. 1999. p.49. Interpretive Summary: Technical Abstract: Digenetic trematodes are parasites having complex life cycles that often involve snails, birds, and fish. Three of these, Clinostomum complanatum (yellow grub), Bolbophorus confusus, and an unidentified digene are causing problems in farm-raised fish across the South. The yellow grub has recently affected some catfish sales at processing plants in Mississippi and Arkansas and has resulted in the destruction of at least one large group of fingerling sunshine bass in North Carolina. It infects the muscle tissue and can remain live in that tissue for more than three years. Bolbophorus confusus has infected fathead minnows in North Dakota and has caused severe fish losses on two catfish farms in Louisiana. It also infects muscle tissue. An unidentified trematode has had devastating effects on the aquarium industry causing, in some cases, the closing of production facilities. It infects the gills and causes massive cartilage proliferation. This same trematode is infecting wild fish in Texas and has been experimentally shown to cause disease in catfish, sunshine bass, fathead minnows, goldfish, golden shiners, and KOI carp. |
