Fisheries
These human-run ocean systems supply much of the world’s seafood but can also disrupt marine ecosystems.
What are fisheries?
This parasite causes respiratory distress, and often leads to respiratory failure.
What are lungworms?
A primary nongovernmental organization that provides guidance on the conservation of cetaceans and management of whaling.
What is the International Whaling Commission?
Stress caused by changing prey distributions due to overfishing suppresses this bodily system, making cetaceans more vulnerable to disease.
What is the immune system?
The classification for the suborder of cetaceans that have symmetric skulls and baleen plates.
What are mysticetes?
or
What are Baleen Whales?
This major threat occurs when whales or dolphins become accidentally caught in fishing nets or gear.
What is bycatch?
The fungal disease Lobomycosis causes damage to this organ - the largest organ of cetaceans.
What is skin?
This is a major human-caused contributor to the threat to cetacean populations around the entire world.
What is climate change?
Entanglement in this type of equipment not only causes injuries in cetaceans, but also increases their risk of developing secondary infections.
What is fishing gear?
This specialized, fatty organ, located in the forehead of odontocetes, is used for focusing and directing sound for echolocation.
What is the melon?
Overfishing leads to a shortage of krill and small fish, the main prey for mysticetes, creating this kind of problem.
What is food competition?
This viral infection in cetaceans often leads to issues with ability to stay afloat, causing mass stranding.
What is Morbillivirus?
What is Marine Spatial Planning?
Outbreaks of morbillivirus in dolphins & whales are often made more severe when animals have weakened immune systems due to exposure to these industrial chemicals that bioaccumulate.
What are persistent organic pollutants (POPs)?
What is "to birth and nurture calves"?
By releasing nutrient-rich waste near the ocean’s surface, whales support plankton growth through this ecological process.
What is the whale pump?
Infection with Herpesvirus can cause skin lesions that cause cetaceans to be more susceptible to other pathogens and opportunistic infections due to this condition.
What is immunodeficiency?
When collecting biological samples from cetaceans, it is important that researchers keep this key safety precaution in mind.
This approach to regulating fisheries aims to consider whole food webs, including how much prey must be left for predators like cetaceans.
What is ecosystem-based fisheries management?
This sensory adaptation allows cetaceans to withstand extreme pressure changes during deep dives by collapsing safely.
What are flexible rib cages?
Name all 3 key management strategies designed to balance fishing activity with cetacean conservation.
What are sustainable fishing, safer gear, and marine protected areas?
While both toxoplasma gondii (a parasitic disease) and brucellosis (a bacterial disease) can cause reproductive issues such as stillbirths and abortions, this disease can also manifest in osteomyelitis, the infection of bone marrow.
What is Brucellosis?
This is one of the only populations of odontocetes that are *currently* covered by the IWC's Conservation Management Plans.
What is the South American River Dolphin?
The relationship between fisheries, immune suppression, pollutant load, and infectious disease outbreaks in cetaceans exemplifies this type of ecological framework that examines multiple stressors acting together.
What is a cumulative impacts model?
This organ in mysticete whales expands dramatically during feeding to take in huge volumes of water & prey.
What is the ventral throat pleats (or expandable throat grooves)?
