Most catfish farmers do not make efforts to manage water quality. This causes high organic matter. Therefore, water management is carried out through the Recirculating Aquaculture System (RAS). Continuous use of water in the RAS system causes filter performance to decrease, so technological improvements are needed with the addition of probiotics. The research was conducted on 22 February – 23 March 2021 at the Chemistry and Analysis Laboratory, Faculty of Fisheries and Marine, Universitas Airlangga to determine the influence of probiotic additions on the RAS system total organic matter and the survival rate of catfish.The study was conducted experimentally using RAL by adding different doses of probiotics, namely P0 (Control), P1 (0.5 ml/L), P2 (1 ml/L), P3 (1.5 ml/L) and P4 (2 ml/L ) with four replays. Data analysis using ANOVA and DMRT showed that the addition of probiotics in the RAS system has an effect (p<0.05) on total organic matter and survival rate. Organic matter was highest at P2 (46.89 mg/L) and lowest at P2 (34.07 mg/L). Survival rates were highest at P2 (85%) and lowest at P0 (71.25%).

“…When viewed from the stability, based on the Shannon-Wiener diversity index, Cirata Reservoir water is categorized as low community diversity and stability (Basmi, 1999). In such circumstances, this can easily affect the structure and composition of the genera, even by relatively small environmental changes (Tarunamulia et al, 2016).…”

The quality of reservoir waters depends on changes in their physical, chemical, and biological components. Changes in these parameters lead to the emerging of many problems in the reservoir, such as eutrophication and changes in the composition of the phytoplankton community in the reservoir ecosystem. This eutrophication impact can trigger an explosion of dangerous phytoplankton population, such as blue-green algae (Cyanobacteria). Research on the relationship between water quality and the community structure of Cyanobacteria has been carried out. This study used secondary data from the water monitoring report of the Cirata Reservoir from 2013-2017. This study aimed to obtain information on the community structure of Cyanobacteria and environmental parameters that affected the abundance of Cyanobacteria in the reservoir. Species abundance, diversity index, and dominance index were analyzed to determine changes in the community structure of Cyanobacteria in each of the years. Cyanobacteria abundances were classified using cluster analysis. Water quality parameters such as temperature, transparency, pH, carbon dioxide, nitrate, nitrite, and zooplankton abundance as independent variables, and levels of Cyanobacteria abundances as the dependent variable was analyzed using discriminant analysis. This study showed that the abundance of Cyanobacteria in the Cirata Reservoir is dominated by the Stanieria (a genus of the Pleurocapsales order) every year and the parameter that significantly affects the level of Cyanobacteria abundance was nitrate (NO3-N).

“…Increased diversity of Cyanophyta and Chlorophyta types of plankton which usually tends to be followed by an increase of primary productivity in pond waters. Making these conditions, sometimes will have a negative impact both ecology, economy or environmental health (Tarunamulia et al, 2016). Whereas Vibrio sp is a type of gram-negative bacteria that is opportunistic pathogenic towards vannamei shrimp (Cardenas et al, 2017).…”

The abundance of Vibrio bacteria and the presence of an excess Oscillatoria sp plankton type are the main problems that often arise in intensive vanamei (Litopenaeus vannamei) shrimp culture. To examine this problem, the purpose of this study was to determine of model approach interaction between the abundance of Vibrio and Oscillatoria sp with the shrimp growth rate in ponds. This research was conducted with the expose facto design on intensive shrimp culture operations in Bayeman Village, Probolinggo. The results data from field research variable are analyzed using a dynamic modeling system. From the modeling analysis results, showed that the Oscillatoria sp abundance pattern tended to increase over with shrimp culture period as following the pattern of tropical status dynamics by the nutrient increase load of 16.37%/week in ponds ecosystem. Meanwhile, the increase of Vibrio colonies density in ponds continued to increase aggregately by 0.99%/week on nine weeks and 12.5%/week on the last eight weeks of shrimp culture periods. So, it can be concluded that the fluctuations density of vibrio and Oscillatoria sp bacteria in ponds is are bioecological responses from increased nutrient loads and other micromaterials in ponds due to the longer period of shrimp culture.
