Offshore fish farming is big business, with big profits, big machines, and very big risks. In this episode, host Mike Davidson goes on perhaps his most physically demanding mission yet, joining the crew of Open Blue as they transport a school of Cobia whitefish worth $300,000 in future sales. For three days, he'll battle ocean waves, dive in shark-infested waters, and assist in excruciating repairs to ship engines and feeding dosers. And just when it looks like smooth sailing ahead, Mother Nature steps in to show who's really in charge.
