Land-based salmon farmer Atlantic Sapphire harvested nearly 29 percent more fish during the first six months of 2021 than it did during all of 2020, but problems obtaining oxygen for its fish tanks could impact the full-year's harvest, the company said in an update on Thursday.

Atlantic Sapphire produced 1,275 metric tons of head-on, gutted (HOG)salmon in the first six months of 2021, up from the 989 metric tons produced in 2020, despite fish losses at both its Miami Bluehouse and Danish facility this year.
