Background information and definitions
Large hooks may be more difficult for birds to swallow and so may reduce bycatch rates. A correlative study found a negative relationship between hook size and bycatch rate (Moreno et al. 1996). However, large hooks may be more likely to hook birds through the body or wings (‘foul hooking’).
