A Round River Provisions Company

good fish harvested right

Turning Tide Provisions was founded under Round River Provisions to build a seafood supply chain that works for the fishery and the shopper at the same time.

Most tinned fish moves through traders who profit on the gap between what a vessel gets paid and what a retailer pays. We buy direct instead, from vessels we monitor, landed in ports we operate through. That removes a layer of cost and a layer of guesswork at the same time.

Done right, tuna fisheries can supply the world with a healthy, renewable and affordable source of protein.
