Size and Age Structure of a Single School of Striped Bass in Lake Greeson, Arkansas

A school of 206 striped bass, Marone saxatilis, were sampled using rotenone in a deep, southwest Arkansas reservoir. Fish averaged 439 mm TL and 823 g in weight, ranging in size from 321 to 525 mm TL and 33.5-1,389 g. K factors were extremely low, ranging from 0.82 to 1.18. Two hundred four of the striped bass were age II+ (1981 year class), while only 2 were age I+. Several possible reasons are considered as the causative agent in the formation of this large school.
