According to a report by Japan's Marine Economic News on January 15, 2026, the scallop yield along the coast of Hokkaido's Sea of Okhotsk is expected to decline by approximately 15% in 2026, with total production projected to fall to 215,000 tons. This forecast not only signifies a continued drop in production but also portends a new round of supply tightness and price volatility in the global seafood market.
2026 Hokkaido Scallop Production Outlook

Analysis of the Output Decline
The anticipated reduction in scallop output is attributed to a confluence of ecological and regulatory factors, rather than a single cause.
Ecological Factor: A severe shortage of plankton, the scallops' primary food source, has significantly impacted their growth rates and survival over the past two years.
Regulatory Factor: To ensure sustainable fishing practices, management authorities have strictly enforced a rotational harvesting system, which has limited the intensity of fishing operations.
Regional Impact Variance
The decline in production is not uniform across all regions. The northern area of Wakkanai has been disproportionately affected.

Implications for Global Markets
As a major supplier of wild scallops, Hokkaido's reduced output is poised to have significant ripple effects:
Supply Chain Disruption: The anticipated drop in supply is likely to create bottlenecks for global distributors and retailers.
Price Volatility: Reduced availability will almost certainly drive up market prices, affecting both the foodservice industry and end consumers.
Strategic Sourcing: Buyers may be compelled to seek alternative sources or increase their reliance on aquaculture products to meet demand.
