Environmental effects of marine fishing



  • 1Some effects of fisheries on the associated biological systems are reviewed and management options and their inherent risks are considered.
  • 2In addition to the effects on target species, other sensitive groups impacted by fishing are considered including marine mammals, turtles, sea birds, elasmobranchs and some invertebrates with low reproductive rates.
  • 3Other impacts discussed include the destruction of benthic habitat, the provision of unnatural sources of food and the generation of debris.
  • 4Management options are considered including the designation of marine protected areas, risk aversion, and the burden of proof.
  • 5A balanced consideration of the risks and consequences of ‚Type 1’ and ‚Type II’ errors is advocated.
