Abstract:
This study aimed to determine the effect of average water quality parameters on gonad maturity of
marble goby (Oxyeleotris marmorata) fed with earthworms. This research was conducted in Awang
Village, East Bangkal, Banjar Regency, South Kalimantan. The data was analyzed by using regression
analysis. The results of the analysis of water quality parameters, namely temperature, dissolved DO,
CO2, pH, and NH3 in the research container were related to the number of marble goby that were
TKG (spell, please) IV in several treatments. Treatment 30 cm water height, earthworm feed without
vitamin E, 30 cm water height, earthworm feed + vitamin E 75 mg kg-1 , 30 cm water level, earthworm
feed + vitamin E 85 mg /kg, water height 50 cm, earthworm feed without vitamin E, water height 50
cm, earthworm feed + vitamin E 75 mg/kg, water level 50 cm, earthworm feed + vitamins E 85 mg/kg.
The results showed that the regression equation between the temperature of the parent Gonad
Maturity Level IV is R2 = 0.0172, DO with a number of parent Gonad Maturity Level IV is R2 = 0.2737,
CO2 by the number of parent Gonad Maturity Level IV is R2 = 0.0238, pH with the number of parents
with Gonad Maturity Level IV is R2 = 0.2787, and NH3 with the number of parents having Gonad
Maturity Level IV is R2 = 0.0816.
Keywords: water quality parameters, marble goby, earthworms
