Abstract

A study was conducted to determine the potential of the white amur (Ctenopharyngodon idella Valenciennes) as a sport fish based on catchability, organoleptic properties, and effects on existing fish populations as evidenced by stomach analysis. Catchability on four baits and lures proved to be low (.0046) but was complicated by high mortality (62%) for study ponds. Organoleptic evaluation was performed by a 28 member taste panel; when white amur was compared to largemouth bass and bluegill, no significant difference in taste was found at the .05 level. Channel catfish was significantly different from white amur, bluegill, and largemouth bass. Stomach analysis revealed high consumption of animal matter (Chironomidae, Chaoborus, Pelecypoda (Sphaeriidae), and Trichoptera) in three study ponds. Reduction in plant densities was noted but turbid conditions in study ponds was thought to be a major factor. It was concluded that the white amur has marginal potential as a sport fish.
