| 11609566619 | fishery | concentration of particular aquatic species suitable for commercial harvesting in a given ocean area or inland body of water | 0 | |
| 11609566620 | fishprint | area of ocean needed to sustain the consumption of an average person, a nation, or the world | 1 | |
| 11609566621 | Asian carp | Fish, outcompeting native fish in the Mississippi River system by eating a tremendous amount of plankton and leaping from one body of water; threaten to enter the Great Lakes | 2 | |
| 11609566622 | commercial extinction | overfishing leads to a time when it is no longer profitable to continue harvesting the affected species | 3 | |
| 11609566623 | purse-seine fishing | when large fishing vessels enclose a school of fish near the surface or in shallow areas which have been known | 4 | |
| 11609566624 | drift-net fishing | fish are caught by huge drifting nets that can hang as deep at 15 meters (50 feet) below the surface and extend to 64 km (40 miles) long | 5 | |
| 11609566625 | exclusive economic zones | a country's offshore fishing zone extends to 370 kilometers (200 nautical miles) from its shores. When a foreign fishing vessel takes a certain quota with the government's permission, it occurs in this zone. | 6 | |
| 11609566626 | marine protected areas (MPAs) | the global system of areas of ocean partially protected from human activities; there are more than 4,000 MPAs (write it out) worldwide | 7 | |
| 11609566627 | integrated coastal management (ICM) | a community-based effort to develop and use coastal resources more sustainably | 8 | |
| 11609566628 | sustainable seafood | bottom-up pressure from consumers demanding more responsible fishing practices | 9 | |
| 11609566629 | mitigation banking | this allows destruction of existing wetlands as long as an equal area of the same type of wetland is created or restored | 10 | |
| 11609566630 | zebra mussel | a thumbnail-sized mollusk that reproduces rapidly and has no known natural enemies in the Great Lakes. It has depleted the food supply for other aquatic species, clogged irrigation pipes, water supplies, fouled beaches, and jammed ship's rudders | 11 | |
| 11609566631 | trawler fishing | this involves dragging a funnel-shaped net held open at the neck along the ocean bottom. It is weighted down with with chains or metal plates scrapping up almost everything that lies on the ocean floor and often destroys bottom habitats (think ocean clear cutting) | 12 | |
| 11609566632 | long-lining | this fish catching process involves putting out lines up to 100 km (60 mi) long, hung with thousands of baited hooks, that catch not only fish but endangered sea turtles, dolphins, and seabirds each year | 13 | |
| 11609566633 | bycatch | unwanted marine animals caught with the commercial catch | 14 | |
| 11609566634 | high seas | ocean areas beyond the legal jurisdiction of any country where it is hard to monitor and enforce the laws and treaties pertaining to them. | 15 | |
| 11609566635 | marine reserves | areas that are declared off-limits to destructive human activities in order to enable their ecosystems to recover and flourish | 16 | |
| 11609566636 | individual transfer rights / fish shares | allows countries to catch certain quantities of fish and to sell or lease their shares | 17 | |
| 11609566637 | aquaculture | fish farming operations | 18 | |
| 11609566638 | sea lamprey | parasite that attaches itself to almost any kind of fish and kills the victim by sucking out its blood | 19 | |
| 11609566639 | quagga mussel | a larger and more potentially more destructive species, this mollusk can survive at greater depths and tolerate more extreme temperatures. It has reduced the food supply for many fish and other species causing major destruction to Lake Michigan's food web. | 20 | |
| 11609566640 | lionfish | invasive species which destroys fish that inhabit coral reefs | 21 | |
| 11609566641 | ocean acidification | when CO2 dissolves in seawater, it reacts with water to form carbonic acid, which lowers ocean pH | 22 | |
| 11609566642 | carbonate ions | component ofshells | 23 | |
| 11609566643 | Atlantic cod fishery | a fishery which collapsed due to overfishing | 24 | |
| 11609566644 | jellyfish | free-swimming sea animal with a bell-shaped, jelly-like body and stinging tentacles; population is increasing rapidly due to absence of predators, warmer waters, and nutrient runoff which increases plankton, on which they feed; threaten to take over entire ecosystems | 25 | |
| 11609566645 | sharks | a keystone species of the ocean which is threatened by extinction due to fishing for shark fin soup and for meat | 26 | |
| 11609566646 | maximum sustained yield | harvesting at a level that produces a constant yield without forcing a population into decline | 27 | |
| 11609566647 | optimum sustained yield | takes into account interactions among species and provides more room for error | 28 | |
| 11609566648 | multispecies management | estimates a number of interacting species, taking into account their predator-prey relationships | 29 | |
| 11609566649 | catch-share system | fishermen share the catch so that everyone has a part of the total allowable catch | 30 | |
| 11609566650 | sea turtles | in danger of extinction due to pollution, hunting for shells and eggs, rising sea levels, and destruction of coral reefs by trawling | 31 | |
| 11609566651 | plastic ocean pollution | kills birds and mammals which think it is food | 32 |
