Fish producer Maruha Nichiro starts using smart feeding device UMITRON CELL2


Umitron K.K. has begun offering the smart feeding device "UMITRON CELL2" to Maruha Nichiro Corp., the world's largest fishery operator, to help with the establishment of sustainable domestic salmon trout farming.


UMITRON CELL2 is an improved and upgraded mass-production model of UMITRON CELL1", which has become a part of Maruha Nichiro's domestic salmon farming in Saga prefecture and offers these solutions:


・ Remote monitoring of reared fish in the fish pen

・ Automatic accumulation of feed data

・ Detailed and real-time adjustment of feed timing and amount


It is said that a relatively lower water temperature is suitable for the aquaculture of trout salmon. When salmon trout is cultivated in Japanese fishing grounds, all of the livestock has to be shipped out by spring when the water temperature rises, so the suitable growing season is limited to a very short period in winter.


This limited time period within which to achieve a marketable shipping size has been a big obstacle to profitable trout salmon farming in Japan, and one way to solve this issue is to refine the feeding operation, such as changing the feed timing, quantity and the number of times the fish are fed.


The solutions that an improved and upgraded production model, UMITRON CELL2, offers can now contribute toward establishing an optimised feeding operation.


In particular, the UMITRON FAI (Fish Appetite Index), a newly developed algorithm, automatically evaluates the fish's eating condition using artificial intelligence (AI), and allows for a more detailed and optimised feeding operation that matches the appetite level of the fish. This in turn further reduces the environmental impact and labor burden on aquaculture farms.


UMITRON CELL can also monitor the condition in the fish pen as affected by various environmental and ecological factors. With this information, the UMITRON CELL optimises the feeding operation by allowing a flexible adjustment of feeding time, amount and speed. Traditionally, such detailed feeding management would be time- and labour-intensive.
