JANTANISASI ANAKAN IKAN GUPPY (POECILIA RETICULLATA) MELALUI PERENDAMAN INDUK DENGAN LARUTAN 17a-METILTESTOSTERON
ABSTRACT: This study aimed to
investigate the effect of different 17α-methyltestosterone concentrations
toward the ratio of male guppy fish seedlings. This study was implemented
in Laboratory of Local Fish Hatchery of
Gandus, Palembang. The research method used was complete random design
consisting of 4 treatments and 3 repetitions. The implemented treatments were
guppy fish parent soaking in 17α-methyltestosterone solution of various
concentrations namely: 0 mg.L-1 (D0), 2.5 mg.L-1 (D1), 5 mg.L-1 (D2), and 7.5 mg.L-1
(D3). The observed parameters consisted of percentage of male seedlings and
viability of guppy fish seedlings during the raising as well as
physical-chemical parameters (temperature, pH, and dissolved oxygen). The trial
result indicated that the administration of 5 mg.L-1 (D2) of
17α-methyltestosterone solution could increase the percentage of male guppy
fish seedlings up to 55.40% and quite high viability during the raising for
83.79%. The range of physical-chemical water value during this study still supported
the raising of parents and seedlings of guppy fish.
