Japan's researchers feed groupers "on land"
(02-04 17:40)
A team of dedicated aquaculture researchers at an institute in the southwestern Japanese prefecture of Nagasaki began Monday an experimental project to feed kelp grouper at an onshore facility, local officials said.
The aquaculture project aims to shorten the raising period to two years instead of four years it currently takes in offshore cage, controlling the temperature of water to keep the fish best alive and also to farm fast in the facility, according to Nagasaki Prefectural Institute of Fisheries, Xinhua news agency reports.
The team released 300 kelp grouper fry, each of those weighs around 600 grams, into a 22-ton aquarium installed at one of the institute's buildings located near to the coast in Nagasaki City on Monday, and officially announced the start of the aquaculture project.
Sumihiro Yamamoto, director of Aquaculture Division of the institute, told Xinhua that the team would try to establish a new way of fish farming using kelp grouper, which has plenty of fat and is known as high-quality fish in Japan, and to commercially produce the fish species "on land" within years.
The institute will eventually raise a total of 3,000 groupers stocked in onshore fish tanks, which can be warmed up by geothermal heat, in the project which will continue February next year, the director added.
