Stlhdr1,

You need to compare catch per landing of the alternative gear with gillnet catches. Since beach and purse seine gear requires a larger crew and more expensive gear, the catch per landing needs to be significantly greater than with a gillnet boat that can be manned and operated by one fisherman. Absent the higher catch per landing, there is no profit from alternative gear. Which is why my suggestion to retrofit traps to existing fish ladders is the selective alternative that actually makes economic and biological sense.
