PERTUMBUHAN IKAN KUWE PUTIH CARANX SEXFASCIATUS DI KARAMBA JARING APUNG YANG DIBERI PAKAN RUCAH DENGAN BAHAN TAMBAHAN YANG BERBEDA
ABSTRACT: The use of trash
fish ( Treatment A ), trash fish + cassava( Treatment B), pellets+ trash fish (
Treatment C) and a mixture of trash fish + cassava + pellets ( Treatment D ) as
feed had been conducted to evaluate its effect on growth of Caranx sexfasciatus.
This research was carried out inTelengen Bay waters, Central Tabukan District,
Sangihe Islands Regency. Fish with weighing 60,9 -62,9 g were distributed in 12
net cages measuring 3x1x1 m with the density of 5 fish each. Fish were fed
three times a day for seven weeks. Fish weight was measured every week. At the
end of experiment, the individual weight of fish ranged from 168,7 to 222,8 g
in with the highest average weigth gain was achieved in treatment A namely
222.8 g (354.2%)), followed by treatment C 178.0 g (286.6 %) treatment D 170.08
g (280.5%), and treatment B as much as 168.7 g (274.3%). Statistical analysis
displayed that weight gain of fish in treatment A was significantly different
as compared to that of treatments B, C, and D. There was no significant
differencesbetween treatment B, C, and D. Food conversion ratio of treatment A
was significantly different compared to other treatments. Food conversion ratio
of treatment A was 2.80, B 4.25, C 3.70, D 3.88. as conclusion, the use of
trash fish without supplementaion with others ingradients resulted in the
highest absolute and relatif growth of fish and the lowest food conversion
ratio of 2.80 as compared to other treatments.
