A semi-manual prototype, at 60% scale of the full intended capacity,
having a motor-driven perforated drum, was built to
demonstrate the feasibility of the development. Species from the
Atlantic Ocean and carps from inland waters were processed in
short batches. Selected marine species were: white croaker (Micropogonias
furnieri), brazilian flathead (Percophis brasiliensis), red
porgy (Pagrus pagrus), silver warehou (Seriolella porosa), and king
weakfish (Macrodon ancylodon).
