Aquatic History
Define aquaculture
Providing food and livelihoods through the farming of marine species
What is a recirculating aquaculture system?
A type of aquarium system that reuses water and minimises waste.
Regular water testing that is crucial for maintaining optimal conditions in aquariums
Explain the difference between open and closed aquaculture systems, highlighting their environmental impacts.
open systems are more cost-effective and scalable but have higher environmental risks, while closed systems are more sustainable but more expensive and complex to manage
Compare wild-caught fishing and aquaculture in terms of environmental impact.
Aquaculture can have controlled impacts, while wild-caught fishing affects natural ecosystems.
