''Hooking Location
The location of hooking has been shown to affect catch-and-release mortality. Catchand-
release mortality of white seabass was directly related to hooking location, and all
mortalities involved hook damage to the visceral region (Aalbers et al., 2004). Similar results
have been found for largemouth bass in which 56% of fish hooked in the esophagus died, while
the mortality of fish hooked in other areas was not significantly different than fish that were not
hooked at all (Pelzman, 1978). Dextrase and Ball (1991) found that hooking mortality of lake
trout was largely restricted to those fish that were deeply hooked. Mortality in northern pike was
also greater in fish that were deeply hooked (Dubois et al., 1994). Schisler and Bergersen (1996)
reported that mortality of rainbow trout was significantly greater for fish hooked in the gill
arches or esophagus than superficially hooked fish, and this increased mortality was attributed to
bleeding intensity associated with hooking location. These studies all point to the fact that fish
which are deeply hooked suffer increased mortality."
