Should companies prioritize sustainable water practices even if it increases the price of goods?
Warming water temperatures have caused shifts in the migration and seasonal availability of fish like tuna, mackerel, and rockfish. These changes create new challenges for food sourcing, affecting when certain seafood appears in markets and restaurants.
Why it matters
Changes in marine ecosystems present long-term stability risks for food and beverage supply chains. As ocean temperatures rise, the seasonality of the fish you purchase may shift, requiring adjustments in how markets source and manage their inventory.
Current industry reporting confirms that warming water temperatures are triggering northern shifts in rockfish migration patterns and earlier spring availability for tuna and mackerel. These findings are supported by corporate sustainability assessments regarding water risk.
The players
PepsiCo
A global food and beverage company that utilizes water for ingredient processing, irrigation, and factory sanitation.
Suntory
A global beverage and food company that sponsored the Axios House event at Climate Week.
The details
Food and beverage companies are increasingly utilizing advanced water-recycling technologies, such as membrane bioreactors, to maintain potability across factory operations. Restaurants are also adapting to supply variability by adopting whole-fish butchery, a practice that helps manage both labor costs and the quality of shifting seasonal inventory.

Health Landscape
This focus on sustainable sourcing reflects a broader trend of integrating environmental risk management into the food supply chain. It follows discussions held during Climate Week regarding the necessity of protecting water resources for food production.
As seafood migration patterns shift, you may notice different peak availability windows for various fish species at your local market. It is worth noting these seasonal changes when planning meals and discussing sustainable seafood options with your trusted fishmonger.
The takeaway
The shifting migration of marine life underscores the interconnectedness between climate change and our food supply. Being aware of seasonal shifts can help you make more informed decisions about the fish species that are most abundant and sustainably sourced in your area.
