It is important in a RAS design that fish handling/logistics is addressed. Fish have to be graded or vaccinated in a RAS and this will be included in most designs, but often overlooked in a RAS is the harvesting procedure. 

IAA will often in conjunction with a typical round tank system have a harvest section consisting of one or two raceways where fish can be easily sluiced into. Raceways are easy to work with in respect of crowding and fish harvest. In our COMBI HarvePurge, we can carry out grading, purging and harvest.
