What is extensive aquaculture?

Extensive aquaculture is a type of aquaculture where the fish are grown at low densities, typically in large ponds or lakes, and rely primarily on natural food sources such as algae and zooplankton for their nutrition. This method of aquaculture is often less intensive and requires minimal infrastructure and input compared to other forms of aquaculture. Extensive aquaculture is primarily used for the production of fish such as carp, tilapia, and catfish.
