Normally, cultivation of Hamachi involves raising about 3,000 fish in a small preserve. Conversely, our Hiro-Biro Ikesu preserve cultivates about 20,000 Hamachi in an area which is approximately 48 times larger than normal. If conventional cultured Hamachi are compared to generic chicken for broiling, our Hiro-Biro Ikesu Hamachi can be compared to local brands of free-range chicken.
Sparse rearing allows fish to get abundant exercise and gives Hiro-Biro Ikesu Hamachi firm flesh. Moreover, sparse rearing encourages the healthy growth of fish and makes it possible to minimize the administration of medicine.
