Feed Sustainability & Technology: Fit for Future
Abstract
China is the largest producer of aquafeeds, accounting for about 40% of the global production. Due to the variety of aquaculture species and farming modes, its aquafeed industry exhibits a rich diversity, from millions of tonnes of feeds for grass carp to hundreds of tonnes of feeds for some minor species. Based on annual production volumes, aquafeed enterprises can be categorized into four groups (in tonnes), from ≥1 million, 0.5-1 million, 0.1-0.5 million and < 0.1 million. The top 3 aquafeed giants (≥1 million tonnes) contribute nearly half of the national output.
In the future, aquafeed production will become more centralized with fewer enterprises. The scarcity of feed resources, environmental protection pressures, and an increasingly saturated market, are posing serious challenges to China's aquafeed industry. To reduce dependence on imported feed ingredients such as fishmeal, some novel proteins sources, such as insect meals, single-cell proteins, will be increasingly included in aquafeed formulations. More pre-treated ingredients such as fermented soybean meal, enzyme-hydrolyzed proteins and some functional additives will be used to improve feed utilization and aquatic animal health.
Facing greater competition, Chinese enterprises will establish more companies in Southeast Asia, Latin America, and other regions, promoting the development of local aquaculture and aquafeed production.
