Proximar Seafood reports steady biomass growth in Japan during Q3 2025
Company records higher production volumes as fish reach market size despite operational adjustments
JAPAN – Proximar Seafood has reported continued growth in its salmon production at the Oyama facility in Japan, with a standing biomass of 1,389 tonnes as of September 29, 2025, compared to 1,294 tonnes at the end of the previous quarter.
During the third quarter, total biomass growth reached 524 tonnes, which included 429 tonnes that were harvested within the period.
The Norwegian-Japanese company currently operates 21 batches, comprising approximately 2.2 million Atlantic salmon across different stages of production.
Harvest volumes for the quarter amounted to 356 tonnes head-on gutted (HOG), raising the company’s total harvest for the year to around 1,000 tonnes.
Proximar explained that growth during the quarter was slowed by fish transfers into the final production module and changes made to its feeding systems.
However, the company noted that it has implemented several improvements and is continuing to fine-tune feeding operations to maintain consistent growth performance.
The company’s salmon achieved an average net selling price of about US$5.80 (NOK64) per kilogramme in the third quarter, influenced by softer market prices, currency fluctuations, and a higher proportion of smaller fish weighing around three kilogrammes.
Larger fish exceeding three kilogrammes fetched approximately US$8.52 (NOK94) per kilogramme, representing a price advantage compared to imported salmon in Japan.
The average harvest weight during the quarter was 2.33 kilogrammes HOG, with 99.2% of the fish classified as superior quality.
Operational performance and outlook
Chief Executive Officer Joachim Nielsen said that production and harvest results for the quarter reflected the impact of extensive fish movements and feeding adjustments within the facility.
He highlighted that despite these challenges, the company maintained low mortality rates and a consistently high share of premium-quality fish.
Nielsen added that with all production modules now active, Proximar expects stronger growth rates in the coming quarters.
He also projected that harvest weights will gradually return to three kilogrammes and above as operations stabilize and fish complete their growth cycle.
Proximar Seafood’s Oyama site remains one of Japan’s leading land-based Atlantic salmon farms, with the company positioning itself to meet increasing demand for locally produced salmon in the Japanese market.
