ANALYSIS OF GROWTH OF LALAWAK Barbonymus balleroides (VALENCIENNES, 1842) IN THREE CULTURE METHODS
Abstract: In fish culture,
optimal growth could be influenced by various culture methods. Aim of the study
was to evaluate the productivity of Barbonymus balleroides, lalawak in floating
net cages, concrete ponds, and earthen ponds. Cultivation was designed with the
circulation water system. Experiment was conducted using completely randomized
design with three treatments and three replications for each treatment. The
experimental fish, sized of 4.20 ± 0.64 cm SL and weight of 2.14 ± 0.99 g, were
obtained from induced breeding. The stocking density used was 20
individuals/m3. Fish were fed 3% of total weight two times every day using
commercial pellet with 35% protein content for 90 day. The result showed that
lalawak reared in earthen pond was no significant difference on length, weight,
and biomass compared with that one in concrete pond (P>0.05), but
significantly different (P<0.05) with floating net cages. There were no different
(P>0.05) among the three different culture systems for survival rate and
FCR. Lalawak reared on earthen pond system supported with optimal water quality
could increase productivity value.
