In 2009, MER was hired by two leading fish farms of the island to provide estimates of fish weight and biomass in their cages. MER used Akva-smart Vicass Biomass Estimator system to photograph gilt-head seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) in the cages and estimate their biomass. Reports with analysis of data were submitted to the farmers.
