Salmon farming is a business conducted out in nature and is affected by the daily weather in many ways.

The most difficult part of feeding a sea-level fish tank is the weather. The sea-level fish pond at Japan Salmon Farm (Our subsidiary in Imabetsu-cho, Aomori Prefecture), is located 1 to 2 km offshore. It takes about 20 minutes by boat to get there. When aquaculture first started in Aomori, we used to go to the fish tank by boat and spread food by hand. Since 2019, we have installed an automatic feeding system that spreads the food by machine, so we no longer spread it by hand. However, carrying food to the fish tank and operating the machine was a daily task. Therefore, if the sea is too rough to get to the fish tank, feeding will not be possible.

One way to overcome the problems of weather-dependent feeding is through remote feeding using the barge. The barge can store about two weeks' worth of food, so food replenishment can be done in batches on nice days. Feeding can also be done remotely.
Japan Salmon Farm was the first in Japan to introduce remote automatic feeding using barges in 2022. Our Danish subsidiary, which is an advanced aquaculture company, has already introduced barges, and we plan to utilize their knowledge.

We cannot catch the fish when the sea is rough. This is also a major problem because both Japan and Denmark require that landings be completed within a limited time frame. For example, Danish landings take place between October and December. The weather in Denmark in winter is often bad and changeable. When the weather is bad and the sea is rough, landing boats cannot launch and landings cannot take place. In order to complete the unloading by the deadline, we are required to independently read not only the weather forecast, but also the wind direction and wave conditions.
