Biology of the Striped Bass, Morone saxatilis, in Beaver Reservoir, Arkansas

Growth, length-weight relationship, maturation and food habits of striped bass from Beaver Reservoir were studied. No significant difference in growth in length between sexes was found. Growth of the Beaver Reservoir striped bass was similar to that of anadromous and freshwater populations. Males and females showed significant difference in length-weight relationship, and females exhibited isometric growth. The gonosomatic indices (GSI) of males ranged from 4.50 to 7.09 and were classified as mature fish. Female striped bass with GSI of 2.62 and above had three size groups of ova and were considered as maturing and mature. The food was primarily composed of gizzard shad. Both the possible impact of striped bass on the ecosystem of Beaver Reservoir and future research are discussed

Estimated Growth and Standing Crop of Largemouth Bass (Micropterus salmoides) from Lake Elmdale

Electro-fishing gear was used to make shoreline population estimates of largemouth bass (Micropterus salmoldes) in Lake Elmdale, Washington County, Arkansas, during September 1979. The population density was estimated to be 1541 bass/Km² with a standing crop of 30.4 kg/ha. The length-weight relationship was calculated as W = 0.00001 504L^2.97, and the total length-scale radius relationship as L = 41.75 + 1.23 St. The average condition coefficient(K) was 1.31. In comparison with four other Arkansas lakes the population density of largemouth bass was highest in Lake Elmdale while the growth rate was lowest
