Domestic tuna is here, Hainan successfully breeds 50 kg tuna

From Research to Reality: An Eight-Year Breakthrough The tuna breeding demonstration base in Lingshui Li Autonomous County, Hainan, is China's first innovative project dedicated to deep-sea tuna. Located 3.6 kilometers from the coastline in tropical waters, the base benefits from excellent water quality, a warm climate, and proximity to natural tuna aggregation areas in the northern and central South China Sea, making it an ideal location for tuna farming. As early as 2016, a team from the Chinese Fisheries Research Institute began experimental work, and through relentless efforts, they successfully captured and domesticated wild fry in 2022, achieving a core breakthrough in net cage farming technology. In August 2023, selected wild yellowfin tuna fry from the South China Sea were introduced into the base's gravity net cages, each with a circumference of 90 meters. Today, these fry have grown into giants over 1 meter in length, marking a new height in China's artificial breeding ...
