Abstract
Marine fish farming has been practiced in earnest since 1945 in Japan. The development of marine aquaculture began with the dike type fish culture, and then the small portion aquaculture, which made mass production possible. In recent years, although energy problems remain, the development of environmentally controllable land-based aquaculture technology and the ability to produce seedlings of a wide variety of fish species have led to the expansion of this new industry. On the Miho Peninsula in Shizuoka Prefecture, where Tokai University is located, seawater that has permeated into relatively deep strata can be extracted. The temperature of this underground seawater is constant throughout the year, and because it is oxygen-free, it does not contain larvae or parasites of various organisms. Therefore, it is possible to cultivate marine fish without the cost of temperature control, filtration, or sterilization. Therefore, it is possible to cultivate flatfish, trout salmon, mackerel, and other fish without the risk of Kudoa disease, Anisakis disease, and other organisms, at a low cost.
