Aquaculture is a production activity of breeding, cultivating and fishing aquatic animals and plants under artificial control. Generally, it includes the whole process of cultivating commercial fish or aquatic products from fry under artificial feeding management.
Broadly speaking, it can also include the proliferation of aquatic resources. Aquaculture includes coarse culture, intensive culture and high-density intensive culture. Coarse culture is to put fry in small and medium-sized natural waters and develop aquatic products entirely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive culture is to cultivate aquatic products in small water bodies by feeding and fertilizing, such as pond culture, cage culture and enclosure culture. High-density intensive culture adopts running water, temperature control, oxygen enrichment and feeding high-quality bait, and carries out high-density culture in small water bodies to obtain high yield, such as running water for high-density fish culture and shrimp culture.
