An alternate-tow approach for evaluating performance of the Modular Harvest System relative to a mesh trawl was tested. GLMM and bootstrapping approaches were both suitable for comparing catch rates. Several methods for comparing fish size composition were evaluated. Relative selectivity was more informative than proportions below a specific length. Despite a sample size of 11 tow pairs, data collected during the trial were sufficient to demonstrate some clear differences between the gears.
