Comparison of Single-cod and Dual-cod Trap Nets for Sampling Crappie in Texas Reservoirs

Fisheries Outstanding Technical Paper

Shoreline-set single-cod trap nets are the standard gear used by Texas Parks and Wildlife to assess crappie (Pomoxis spp) populations. In some reservoirs, standardized trap net catch is too low to provide the desired information. In 2006, we compared offshore-set dual-cod trap nets to shoreline-set single-cod and offshore-set single-cod trap nets in ten Texas reservoirs. Catch rates of shoreline-set single-cod trap nets (13.4 fish per net night; F/NN) were similar to each end of the offshore-set dual-cod trap nets (27.1 F/NN when both cod-ends were summed) and all were statistically...
