Gillnet selectivity functions for channel catfish, lake trout, walleye, and white crappie.

Selectivity functions and associated parameters for channel catfish, walleye, and white crappie were collected from Shoup and Ryswyk [14]. Selectivity functions and associated parameters for lake trout were collected from Hansen et al. [13]. The selectivity curves equations relate the mesh size j (mj) to the number of fish of length l capture in that mesh size. The remaining parameters are constants and are defined.
