How do you differentiate between capture fishing, mariculture, and aquaculture?

Capture Fishing: Fishes are captured from natural resources such as lakes, seas, or rivers under this method. Capture fishing is the cultivation of aquatic creatures without the introduction of new stock. Species reproduction happens naturally. This is conducted in the ocean, rivers, lakes, etc. Due to the indiscriminate capture of fish, especially juveniles and fry, the production of captured fisheries falls steadily. Overfishing harms fish populations. Pollution and environmental variables have an effect on the production of fish. There are both good and unwanted species in the catch.


Mariculture: Fish are cultured in the sea or marine water and then collected using this method. Mariculture is the cultivation of marine organisms for food and other animal products in enclosed sections of the open ocean, fish farms built on littoral waters, or in artificial tanks, ponds, or raceways filled with seawater. Finfish, shellfish, oysters, and seaweed are farmed in saltwater ponds. Mariculture produces fish meals, nutritional agar, jewelry, and cosmetics.


Aquaculture: Fishes are cultured in fresh water and then collected using this method. Mariculture refers to aquaculture in saltwater environments and lagoons, not freshwater.  Aquaculture is the regulated cultivation of aquatic creatures such fish, crustaceans, mollusks, algae, and aquatic plants. Aquaculture includes cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural circumstances. Aquaculture that involves cultivating fish for food is called pisciculture.


[Extra information:

India has a large and varied marine and inland fisheries. India is the world's third-largest fish producer and second-largest inland fish producer.

Fishing and collecting wild fish and shellfish constitute harvesting. Aquatic resource exploitation employs artisanal to industrial boats, equipment, fishing gear, and procedures. Capture fisheries capture fish, prawns, lobsters, crabs, mollusks, etc. ]
