What is mariculture?
The cultivation of terrestrial plants
The farming of terrestrial animals
The cultivation of aquatic plants
The farming of marine organisms
Mariculture refers to the farming of marine organisms in saltwater environments, such as oceans, seas, or estuaries. Marine organisms can include fish, shellfish, seaweed, and other aquatic plants. The goal of mariculture is to produce seafood for human consumption, as well as other products like pearls, ornamental fish, and algae for pharmaceuticals and other industries. Unlike wild-caught seafood, which can have negative impacts on marine ecosystems and face issues with overfishing, mariculture can be a more sustainable and environmentally-friendly way of producing seafood. By farming marine organisms, mariculture can help to reduce pressure on wild fish populations and protect marine ecosystems. Hence option 4 is the correct answer.
