Interpretive Summary:

Technical Abstract: Interactions among piscivorous animals, such as double crested cormorants (Phalacrocorax auritus) and largemouth bass (Micropterus salmoides), and economically important fish species are unclear. Increasing numbers of cormorants wintering near Lake Chicot create the potential for negative impacts on sport fish species and are a concern to anglers. However, Arkansas Game and Fish Commission report an increase in the density of largemouth bass in Lake Chicot, which may be having an affect on the sport fish community. Collections of the two predators will be taken seasonally with an additional collection of largemouth bass taken in the summer months. The diet and potential impact of bass and wintering cormorants will be investigated over a one-year period. We will attempt to use bioenergetic models to determine which of these factors is having a greater impact on the mortality of sport fish in Lake Chicot.
