Özet

The present study investigated feed efficiency
and growth performance of juvenile Seabass (Dicentrarchus labrax) cultured in tanks with different colors. Triplicate groups of experimental fish were distributed into 12
tanks, which showed four different tank colors, i.e. red,
blue, green, and yellow. All the fish in the trial received the
same diet for a period of 60 days. Forty fish with an
average weight of 44 g were stocked in the tank. All
experimental tanks were supplied with seawater of 22 ppt
salinity with temperature ranging between 17–20 C during
the course of the experiment. Tank water volume in the
experimental facility of the recirculating aquaculture system (RAS) was set to 40 L. The RAS system consisted of
bio-filtration, UV filtration and gravel-mechanic filtration
units. Results in the present study demonstrated that growth
performance and feed utilization were affected by the tank
colors tested in the trial. It is concluded that the selection of
appropriate tank color might affect economic benefits in
aquaculture facilities.
