Introduction: Silvofishery is an innovative environmentally friendly aquatic cultivation concept that is currently widely developed in coastal areas with various cultivation commodities. The purpose of this research is to analyze the feasibility of saline tilapia (Oreochromis niloticus) as a biological, ecological, and financial commodity for silvofishery cultivation. Methods: This research method utilized a causal ex-post facto design on four silvofishery ponds. The parameters studied include water quality, biological parameters of fish, plankton abundance, and financial feasibility parameters of the business. Results: The research results show that the weight of saline tilapia ranged from 3.01 to 21.24 gr/fish (13.37 ± 6.53) and biomass growth ranged from 3.010 to 19.116 kg (12.886 ± 7.79). Silvofishery water quality parameters resulted in pH data of 7.8-8.2 (8.0 ± 0.14), dissolved oxygen of 4.01-5.92 mg/L (4.90 ± 0.55), temperature of 31.00-32.75°C (31.80°C ± 0.60), salinity of 5-8 gr/L (6.3 ± 1.28), and organic matter of 54.32-73.87 mg/L (62.90 ± 6.33). Plankton abundance ranged from 10,000 to 90,000 cells/ml with the dominance of the genus Chlorella sp. The business feasibility analysis results showed a profit value of Rp. 8,840,000,-, R/C Ratio of 1.55, BEP unit of 297 kg, BEP sales of Rp. 4,428,000,-, profitability of 25%, Net Present Value of Rp. 101,528,000,-, IRR of 20.45%, and payback period of 2.7 years. This means that based on growth performance, pond water quality conditions, and business profit levels, the use of saline tilapia commodities in silvofishery pond cultivation is highly recommended.

Microcytis sp is plankton species that is detrimental in shrimp pond ecosystems. The purpose of this study was to detect the abundance of plankton and the presence of Microcystis sp. in the waters of vaname shrimp (L. vannamei) aquaculture ponds. The research method used is descriptive quantitative and qualitative with added analysis of dynamic modeling systems. The results showed that pond water quality conditions were still good enough for shrimp farming activities with details of dissolved oxygen 4.01-6.17 mg/L, pH 7.7-7.9, salinity 20, temperature 27.050-28.250C, nitrate 0.01-0.15 mg/L, phosphate 0.05-0.20 mg/L, brightness 25-35 cm. For the classification of plankton found among them are from the Bacillariophyceae class, there are the genera Skeletonema sp., Cyclotella sp., Coscinodiscus sp., and Amphipora sp., from the Chlorophyceae class, there are the genera Chlorella sp., Oocystis sp., and Clamydomonas sp., from the Cyanophyceae class. the genus Oscillatoria sp., Microcystis sp., and Anabaenopsis sp. The plankton diversity index (H') was obtained between 0.01-0.33 and the uniformity index (E) was obtained between 0.10-0.50, meaning that the condition of the pond waters is still quite good and there are minimal indications of pollution. The abundance of Microcystis sp. obtained between 0.2x104-0.6x104 cell/ml. from the results of dynamic modeling analysis it is shown that the abundance of Microcystis sp. in pond waters is influenced by the value of the productivity level of the waters and the process of grazing organisms. The results of this study can be concluded that the plankton abundance rate found in ponds ranges from 0.4x104-1.9x104 cell/ml which consists of 10 genera and 3 classes of plankton. Then Microcystis sp. its presence was found in 3 ponds with abundance rate ranging from 0.2x104-0.6x104 cell/ml.Keywords:CultivationGenusGrazingModelWaters
