1979 Global Treaty Migratory Species

Builds global conservation efforts on all migratory species.

1975 Convention on International Trade in Endangered Species

An international convention that combines wildlife and trade themes with a legally binding instrument for achieving conservation and sustainable use objectives.

Marine protected areas (MPAs)

Protected from human activities.

Ocean floor

effect of trawlers

Invasive species

Threaten native species and disrupt and degrade whole ecosystems

Fishery

concentration of a particular wild aquatic species suitable for commercial harvesting in a specific area

Fishprint

area of ocean needed to sustain the fish consumption of a person, country, or the world

Marine and freshwater fish

Threatened with extinction by human activities more than any other group of species

Commercial extinction

no longer economically feasible to harvest a species

Fishprint

Area of ocean needed to sustain the fish consumption of an average person, nation, or the world

Maximum sustained yield (MSY)

the traditional approach

Large marine systems

using large complex computer models

Tilapia

Fishery Regulations

Set low catch limits and improve monitoring and enforcement

Protect Areas

Establish no-fishing areas and establish more marine protected areas

Consumer Information

Label sustainably harvested fish and publicize overfished and threatened species

Bycatch

Use nets that allow the escape of smaller fish

Laws for protection

Zoning laws steer development away from wetlands

Mitigation banking

Can destroy wetlands if create one of equal area

Columbia River

U.S. and Canada

Snake River

Washington state, U.S

Dams

Provide hydroelectric power, provide irrigation water, and hurt salmon

Edward O. Wilson

Completed the mapping of the worlds aquatic biodiversity, identified and preserved aquatic diversity hotspots, created large and fully protected marine reserves, protected and restored the worlds lakes and rivers, and ecological restoration projects worldwide
