Give me one type of aquaculture
Cage, pond, IMTA, recirculating
Why are fish populations on a decline?
overfishing -_-
What is one way to reduce negetives of overfishing
International fishing laws
Aquaculture
tech advancements
Why is overfishing bad
Fish are important and we eat a lot of them......
environmental destruction.....
pollution....
fish population destruction
What type of fishing destroys the ocean floor
Trawling
Which aquaculture method raises fish in indoor tanks where water is continuously filtered and reused?
Recirculating Aquaculture Systems (RAS)
Since 1950, global fish populations have declined by approximately what percentage due largely to overfishing?
90%
What type of fishing technology allows air-breathing animals to escape nets, reducing bycatch?
exclusion devices
What type of abandoned fishing gear can continue killing marine life for decades after being lost at sea?
Ghost Nets
Which method of fishing is often paired with aerial spotting and surrounds schools of fish
purse seine fishing
How does Integrated Multi-Trophic Aquaculture (IMTA) work?
This aquaculture system mimics natural ecosystems by farming multiple species together so that waste from one organism becomes nutrients for another.
In some countries, fish can account for nearly what percentage of total protein consumed by the population?
99%
How can satellite monitoring help reduce overfishing?
to track fishing vessels and improve enforcement against illegal, unreported, and unregulated fishing
Why can some fish populations continue to decline even after fishing stops (specifically trawling)
When habitats and the seafloor are damaged, fish populations that used them as nurseries and homes continue to decline without them.
