Hence, this study aims to examine the phycoremediation capacity of Pb by S. platensis at different levels of salinity. S. platensis was exposed to Pb (4 mg/L) at different levels of salinity (up to 30 ppt) for 12 days. The results indicated that salinity fluctuation was able to reduce phycoremediation capacity of Pb. The highest removal efficiency of Pb was observed in optimum salinity and decreased significantly both in lower and higher salinity treatments. Physiological disturbances in S. platensis were indicated by changes in functional groups and morphology. The morphology of Spirulina platensis both in lower and higher salinity treatments appeared to have changed its shape, resembling a disjointed thread with fading color.]]> Wed 25 Oct 2023 14:58:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:52702 Wed 07 Feb 2024 14:37:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:55891 40 NTU) due to POME contamination significantly decreased total released egg but did not have significant impact on relative weight of released eggs and nest area. Decreased total released eggs was occurred due to several alterations in the reproductive behaviour of siamese fighting fish during both the premating and mating stages. Duration of premating and mating stage was significantly decreased at turbidity level of 60 NTU. During premating stage, the number and average time of fin spreads behaviour at turbidity level of 60 NTU were significantly increased. In addition to, the number of chasing behaviour was significantly decreased with increasing turbidity levels. Furthermore, several alterations in reproductive behavior was also observed in mating stage, including increasing number and average time of lead, copulation interval, number of tail beat, average time of lead, and average time of circlings, followed by decreasing number of leads and number of circlings. In addition to, number of copulation and eggs per copulation showed an increasing and decreasing pattern at turbidity level of 40 and 60 NTU, respectively. The study suggests that reproductive behavior of fish might consider as alternative approach to support POME remediation management, mainly for turbidity parameters.]]> Wed 03 Jul 2024 14:59:32 AEST ]]>
