Overview
• Ocean resources• Development and marine ecosystems• Overfishing• Magnuson-Stevens Act• By-catch/Alt fishing techiniques
• 2006 study by Worm et al. examined the sustainability of our current global fishing industry
• Concluded that within 50 years, most of the important fish species will be economically extinct (Worm, 2006)
Magnuson-Stevens Fishery Conservation and Management
Act• Primary law governing US marine fisheries
– Originated 1976; many amendments since• Main purpose: promote optimal yield • Mandates the use of annual catch limits• Accountability measures to deter overfishing• Calls for increased international cooperation.• Criticisms – failure to stop overfishing,
minimize bycatch, promote accountability
Bycatch• When fishermen are attempting to catch
target fish, many other marine animals are inadvertently captured, such as:– Sea Birds (albatross & petrels)– Marine Mammals (dolphins, porpoises, &
A ratio of 0 would reflect catching target species and nothing else (Harrington, 2005)
Streamers tied to the long line floats which to serve to scare the birds away), they require an investment of time and labor that fishers are not always willing to pay.
