Abstract
Water quality is one of the factors that determine the feasibility and success of the development of grouper mariculture. The objective of this research was to analyze water quality which was prepared for grouper mariculture. This research was carried out in Divur Bay, Dullah island of Tual City. The water quality parameters observed were including temperature, brightness, salinity, pH, current velocity, depth, substrate type, DO, nitrate and phosphate in ten stations spread in Divur Bay. Water quality data were analyzed descriptively. The results showed that Divur Bay was feasible for the grouper culture development with a range of values of temperature, brightness, salinity, pH, current velocity, depth, DO, nitrate and phosphate obtained were 30-31oC; 2.28-7.86 m; 33-35 ppt; 7.7-8.1; 0.06-0.617m/s; 2..28-18.58 m; 3.7-4.8 ppm; 0.0015-0.219 ppm; 0.0076-0.0767 ppm.
Highlights
Mariculture is an important activity that has resulted in nearly half the fish needs of the world and it will increase expectedly in upcoming years (IFPRI, 2003; Wijkstrom, 2003; Hishamunda et al, 2009;. Yulianto et al, 2015)
One commodity that has been cultivated by Dullah island community was grouper aquaculture which belong to be economically important fish species and featured in the development of marine aquaculture in Indonesia (Ghani et al, 2015; Sugama et al, 1986 ; Kusumaningrum, 2015; Asaad et al, 2010)
The time to collect water quality parameter samplings were conducted at 15:00-21:00 WIT and one time sampling in the water column
Summary
Mariculture is an important activity that has resulted in nearly half the fish needs of the world and it will increase expectedly in upcoming years (IFPRI, 2003; Wijkstrom, 2003; Hishamunda et al , 2009;. Yulianto et al, 2015). Hishamunda and Ridler, 2006) , Mariculture is a part of aquaculture which has developed very quickly, especially in the remote and small area (Hishamunda, et al, 2009), where one of them is Tual City in Maluku province. The largest island in Tual city is Dullah island with an area of ± 93.32 km and a population in 2014 was 74 986 people (BPS Maluku Tenggara, 2015). One commodity that has been cultivated by Dullah island community was grouper aquaculture which belong to be economically important fish species and featured in the development of marine aquaculture in Indonesia (Ghani et al, 2015; Sugama et al, 1986 ; Kusumaningrum, 2015; Asaad et al, 2010). Groupers marketed in living conditions have prices almost five times more expensive than dead/frozen ones (Direktorat Jenderal Perikanan Budidaya, 2011; Kusumaningrum, 2015)
