When commercializing "Kurose Yellowtail", we
compared it with Yellowtail supplied by
competitors by conducting a sensory test. First, its
appearance in terms of "redness of flesh" was
found to be superior by a large margin (Exhibit 1).
It also performed well in terms of change in
flesh color over time. The flesh of competitors' Yellowtail from Kagoshima Prefecture and Aichi
Prefecture turned brownish after being stored
at 4ºC for 42 hours, resulting in a loss of
product value, whereas "Kurose Yellowtail"
remained bright red.

The significance of this difference is pointed out by Nissui's fresh fish sales representative.
"Remaining this color for a long time after it is cut into sushi, sashimi or fillets means that sushi
shops and mass merchandisers can reduce their
losses and lessen the frequency with which they
change the selling price. Once the flesh of Yellowtail
turns brownish, it is no longer saleable and has to
be discarded. Since product value can be retained
longer if the color does not change, it makes
operations easier for outlets. Retail outlets can also
expect to reduce their loss rate and improve
profitability by marketing this product."
Nissui aimed to produce a product with "firm flesh
but relatively limited fat, whose redness does not
change quickly." With "KuroseYellowtail", it achieved
this goal and completed a product that can be
recommended to consumers with pride.
Nissui owns the "Gin Gin" brand, a label given only to farmed fish whose history has been
traced from production to shipment and which are perfected to high quality based on unique feed.
"Kurose Yellowtail" has been added to the lineup of products available under this brand, and is being
sold through Nissui's sales network. It can be considered the top product in the "Gin Gin"
series, in the sense that Nissui directly operates the farming farm which produces "Kurose
Yellowtail", whereas coho salmon from the Sanriku coastline marketed under the "Gin Gin"
brand is actually farmed by affiliated aquaculture companies under the guidance and
management of Nissui.
