Artificial reefs are important management tools for red snapper, Lutjanus campechanus, fisheries in the Northern Gulf of Mexico. I deployed fish traps (0.97 m long; 0.64 m height; 175 x 115 mm funnel mouth size) to collect red snapper < 406 mm total length (TL) associated with pyramid-shaped artificial reef structures (3.7 m triangular base; 2.4 m height; 3.2 metric tons) to evaluate two reef distribution designs: (1) five closely-spaced pyramid units, and (2) five closely-spaced pyramids with two sets of two pyramids at 30.5, 61.0, and 91.5 m from the five pyramids. In 26 sampling trips, 927 red snapper were captured. Catch per unit effort (fish/hour) did not differ significantly among patterns (P= 0.396). Red snapper lengths differed significantly among patterns (P= 0.005), with the largest mean total length (235 mm, SE= 5.14) occurring at the pattern with 61.0-m spacing.
