A Comparison of Trotline Catches on Two Hook Types in the Laguna Madre (open access)

A Comparison of Trotline Catches on Two Hook Types in the Laguna Madre

Abstract: Circle hooks caught 3.3 times more fish of each species than straight-shank hooks. The proportion of each species caught on circle and straight-shank hooks was similar. Circle hooks caught smaller (younger) red drum and black drum than did straight-shank hooks. Because the circle hooks catch more red drum and back drum, the potential for mortality by hooking fish in locations other than in the lip is as great for circle hooks as it is for straight-shank hooks.
