In this present study, the effect of salinity and photoperiod on the growth of Nannochloropsis sp. and Tetraselmis sp. was examined to optimize microalgal growth. Different salinities (5, 10, 15 and 20‰) for Nannochloropsis sp. and (10, 15, 20 and 25‰) for Tetraselmis sp. were studied. Both microalgae were cultivated at two different photoperiod cycles (24:0 and 12:12 h light:dark). Maximum growth rates and cell concentrations for Nannochloropsis sp. and for Tetraselmis sp. were achieved at salinities of 10 and 15‰, respectively. In terms of photoperiod, the maximum growth rates and cell concentrations for both microalgae were obtained at photoperiod of 24:0 h light:dark. This study shows that the cell concentrations and growth rates of both microalgae are highly dependent on salinity and photoperiod.Keywords

Measurement of nine water quality parameters were performed every two weeks in two shrimp farms for one production cycle, located in Tuban and Probolinggo, East Java Province, Indonesia. The average productivity for Farm 1 was 17,142.86 kg/ha, with an average size of 17.88 g; while the productivity for Farm 2 was 18,333.33 kg/ha, with an average size of 14.36 g. During the shrimp cultivating period, mean values for salinity, pH and dissolved oxygen (DO) in both the farms were significantly different, whereas temperature in both the farms was not different. TAN, nitrite and orthophosphate concentrations in both the farms were not different. But for nitrate and TSS, the levels are higher in Farm 2 than in Farm 1. The authors conclude that, compared with Farm 1 (water exchange and earthen pond), Farm 2 (zero-water exchange and lined pond) had significantly higher survival rate and higher environmental profits.Keywords

In this study, the effect of salinity (5, 15, 25 and 35‰) on growth and total chlorophyll content of Nannochloropsis sp. BJ17 was evaluated. Moreover, chlorophyll content during logarithmic and stationary phases was investigated. The results showed that maximum cell growth and chlorophyll concentration of Nannochloropsis sp. BJ17 were achieved at the salinity of 15‰. The algae had the higher total chlorophyll concentration in stationary phase than in logarithmic phase. The authors conclude that, the optimum growth and chlorophyll content of Nannochloropsis sp. BJ17 were achieved in salinity of 15‰.Keywords
