TOKYO -- Land-based salmon farming is increasing across the globe as demand grows for raw servings of the fish, mainly in Asia. And the production method is also attracting money from Japanese trading houses, companies and regional investment funds on a rising tide of environmental concerns over conventional sea-based aquaculture.
Sea farming is facing difficulty in boosting output due to a shortage of suitable locations and regional environmental regulations, including Europe. In its place, land-based farming, which places less burden on the environment, has attracted attention in recent years from trading houses and investment funds seeking business opportunities.
