Knowra Marine mammal conservation Marine mammal conservation Marine mammal conservation is the study and management of threats to whales, dolphins, seals, sea lions, manatees, and related species. It combines research, habitat protection, regulation, and population recovery efforts.
Bycatch : The unintended capture of non-target animals during fishing. Fishing gear kills marine mammals directly and can reduce vulnerable populations.
Endangered Species Act : A United States law that protects species at risk of extinction and their critical habitats. It provides listing, habitat-protection, and recovery mechanisms for imperiled marine mammals.
Vaquita : A critically endangered porpoise found only in Mexico's northern Gulf of California. Its rapid decline is linked chiefly to entanglement in illegal gillnets.
Marine mammal management : The regulation and stewardship of marine mammal populations and human activities affecting them. Management applies decisions and rules, while conservation also studies threats and broader recovery goals.
Ocean noise : Sound in the ocean from natural sources and human activities. The population-level effects of chronic and cumulative noise remain difficult to quantify.
Acoustic pollution : Unwanted or harmful sound in the environment, including sound generated by human activities. Shipping, sonar, and seismic surveys can disrupt communication, navigation, and feeding.
Marine Mammal Protection Act : A United States law that generally prohibits the taking of marine mammals in U.S. waters and by U.S. citizens. This law is a central U.S. framework for limiting harm to marine mammals.
North Atlantic right whale : A baleen whale found in the North Atlantic and among the world's most endangered large whales. Ship strikes and fishing-gear entanglement remain major threats to its recovery.
Marine mammal welfare : The condition of an individual marine mammal in relation to its health and quality of life. Welfare centers individual animals; conservation focuses on populations, species, and ecosystems.
Marine mammal entanglement : The trapping of a marine mammal in fishing gear, ropes, or other human-made materials. Estimating hidden deaths and preventing entanglement without undermining fisheries remain challenges.
