Following another mass die-off at land-based salmon producer Atlantic Sapphire’s Miami operations, some analysts are expecting as much as a 20 percent drop in production volumes for 2021.

The company reported the loss of 500 metric tons of fish at its Miami land-based salmon farm on Tuesday, which it blamed on a "weakness" in the recirculating aquaculture system (RAS).

The incident occurred when significant amounts of particles were allowed to flow from the drum filters (particle filtration systems) into the biofilters, the company said in an announcement on the Oslo Stock Exchange on Wednesday.
