PRODUKSI LARVA IKAN RAINBOW MERAH PARROT (Glossolepis incisus) DENGAN JUMLAH SUBSTRAT TALI RAFIA YANG BERBEDA
ABSTRACT: Research on larval
production of Parrot red rainbow fish Glassolepis incisus has been done by
using different numbers of raffia’s rope as substrats for eggs attachment. A raffia’s
rope substrats of different plys concentrations namely A 360 plys, B 720 plys, and
C 1080 plys were used. The spawning was carried out during 30 days, and larval feeding
was given twice a day with frozen Chironomus larvae in ad satiation rate. The results
showed that highest spawning frequencies was found in treatment A (360 plys) with
24 times, and then treatment B (720 plys) with 23 times, and treatment C (1080 plys)
with 18 times. Highest eggs production were found on treatment A, B and C respectively
at 1154 eggs, 892 eggs, and 691 eggs, respectively. Whiles the hatching rate were
found that the treatment A = 92 %, treatment B= 85 % and treatment C= 94 %. The
Treatment A overall was the best treatment in this experiment.
