7.7 Summary
Research and development on land-based shrimp culture of shrimp is advancing rapidly throughout the world, and the past couple of years have seen a great deal of investment in other countries. However, there have not been many workers involved in the field in Japan for the following reasons: (1) a support structure for promoting land-based aquaculture has not been established in this country; (2) energy costs (electricity, heating) are high; (3) the market does not yet consistently value safe and secure aquaculture products; and (4) equipment and materials needed for advanced land-based aquaculture are expensive and difficult to obtain.
However, since the Great East Japan Earthquake of 2011, the domestic situation has changed greatly. In particular, the public’s faith in the safety of seafoods obtained from natural sources is declining. Nevertheless, while aquatic foods produced by land-based aquaculture are safe and tasty, they are still more expensive than fish from the sea, but people willing to purchase them are beginning to increase in number. If government support could be obtained as a component of regional development, then land-based aquaculture of shrimp should become a promising business, especially if costs can be reduced through, for example, the effective use of underutilized energy sources.
