dc.description.abstract | This research investigated the effects of water velocity on somatic growth and
chemical composition of seabass (Lates calcarifer) fingerlings. Three different
water velocities (7, 14 and 21 cm/s) were applied in a 3-week experiment
against the control (0 cm/s). Results showed that survival rate was highest in
the 7 cm/s and 14 cm/s treatments, while it was lowest in the control. In
addition, food conversion ratio was significantly lower in the 7 cm/s treatment
and highest in the control (P<0,05). In the presense of water current fish
tended to develop dorsal muscle, thus increasing the ratio between body height
and body length. The 21 cm/s treatment appeared not appropriate as fish had
lower protein contain, probably due to excessive cost of energy for swimming.
