Description Maturation of most coastal fishes may well be achieved if the
animals are maintained in good quality seawater, provided they
are well fed and reared without the stress of overcrowding
and disturbances. RAS provides perfect opportunity to
manipulate environmental conditions that are critical in
maturation processes such as temperature, photoperiod,
nutrition and other water quality parameters in addition to
facilitating observation of the behaviour of fishes and do
various husbandry steps. There is a need for the development
of cost-effective, economically viable systems that minimize
the environmental impact while at the same time ensuring
optimal rearing conditions. Present article describes design and
operation of low-cost RAS systems developed by ICAR-CMFRI
for broodstock development of marine fishes, which include
30000 to 2000 l FRP systems with mechanical, biological
filtration sub systems including disinfection, temperature
control and photoperiod manipulation, using equipment
such as, proteins skimmer, UV filters, chillers, biological filter
cabinets and LED lighting with timer control.
