The inevitable killing of fish by recreational anglers leads to:

  • fewer fish which can reproduce
  • abnormal changes in the population structure
  • loss of genetic diversity

"Notable effects of high fishing mortality may include depletion of spawning stock (Skurdal et al., 1989), alteration of population structure (Donald and Alger, 1989; Brana et al., 1992), and loss of genetic diversity (Smith et al., 1991)."
