Define aquaculture.
Farming of aquatic organisms in controlled environments.
What is freshwater aquaculture?
Raising aquatic organisms in freshwater environments like ponds or tanks.
What is marine aquaculture?
Raising aquatic organisms in saltwater environments, such as ocean cages.
Define eutrophication.
Excessive nutrient enrichment in a body of water, often due to runoff or pollution.
Why is aquaculture considered efficient?
Uses less space and resources than traditional fishing for food production.
How can aquaculture help wild fish populations?
Can help replenish depleted or endangered fish populations through restocking.
What's a major genetic concern with aquaculture?
Farmed fish escaping can reduce the genetic diversity of wild populations.
Why is biodiversity important in ecosystems?
Key to a healthy ecosystem, providing resilience and stability.
How does aquaculture relate to food security?
Provides a sustainable food source, contributing to global food security.
How can better waste management systems improve sustainability?
Reduces water pollution and eutrophication from aquaculture operations.
How can closed containment systems improve sustainability?
Prevents escape of farmed fish and reduces environmental impacts.
