The Economic Cost of Ignoring Fishery Induced Evolution

Creator:: Faig, Amanda D.
Abstract:: Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....
