*This group of fish had an incidence of high mortality after sea launch and where also harvested around 2.5 kg., due to a public requirement caused by a contagious disease at a nearby location.

**The high FCRe in the fish group in Company 1 sea launched September 2022 is due to the high average harvest weight which was 9.0 kg.
