Abstract
ABSTRACT. The average rate of growth of blue catfish (Ictalurus furcatus) in Lake Texoma as calculated from examination of spines of 192 individuals, 5 to 44 inches in total length, indicated that a length of 5.7 inches was reached at the end of the first year of life, and in suIccessive years, average total lengths of 10.0, 13,8, 17.4, 21.0, 25.8, 30.3, 34.3, 40.4, 42.1, and 44.0 inches were attained. The length-weight relationship of individuals in the lengthrange 9-27 inches is described by the equation logW =--2.9988 + 3.3993 log L, and from 27-45 inches by the equation log W= --3.4110 + 3.7055 log L. The rate of growth was much faster than that exhibited by channel catfish, and nearly equal to flathead catfish growth. Attention should be given to the feasibility of introducing blue catfish into small lakes as a potential sport and food fish.
