Age and Growth of Blue Catfish, Ictalurus Furcatus (Lesueur), in the Recent Delta of the Mississippi River

Age and growth of blue catfish, Ictalurus furcatus (LeSueur), collected on Delta National Wildlife Refuge, Venice, Louisiana were determined by length frequency and the pectoml spine technique. Lengths calculated from p,ectoral spines agree with the length frequency mode for age I fish collected during January, 1965. Three regressions were computed for the data and the cubic equation provided the best fit. This equation indicated that weight increased faster than the cube of the length.
