Abstract

Vibrio sp. and plankton are important microorganisms in shrimp pond ecosystems. The research aims to predict the dynamics of Vibrio sp. and plankton abundance in intensive shrimp pond ecosystems based on causal model analysis. The research method used is an ex-pose facto causal design concept with quantitative descriptive data analysis using causal dynamic modeling. The results showed the water quality in the pond has a high correlation, except Vibrio sp. and alkalinity. In the pond ecosystem 24 genus of plankton from 6 classes. Chlorella sp. is the dominant plankton genus with an abundance of 1.00E+05-4.00E+05 cells/ml. Vibrio sp. abundance in ponds ranged from 1.38E+03 - 1.31E+05 CFU/ml. Based on the results of dynamic modelling, the growth pattern of Vibrio sp. lasted for 30 weeks which was divided into 4 growth phases. The conclusion of this study is that Vibrio sp. will dynamically experience a pure growth rate for 30 weeks with details of the initial growth phase (1-7 weeks), logarithmic growth phase (8-14 weeks), exponential phase (15-21 weeks), and growth declination phase (22-30 weeks). The growth phase of Vibrio sp. has a high degree of similarity to the growth pattern of plankton in the pond water ecosystem correlatively. The novelty of this research lies in the discovery of an estimation model for the abundance of Vibrio sp. and plankton during the shrimp farming cycle. This finding can serve as a fundamental reference for farmers to optimize feeding processes and conduct regular siphoning during the peak abundance of Vibrio sp. and plankton.

Abstract

The stable availability of dissolved oxygen in semi-intensive shrimp ponds plays a crucial role in the sustainability of the aquaculture system. The objective of this study is to determine the trend of the dissolved oxygen carrying capacity for waste absorption during shrimp farming in a semi-intensive system. The method used in this research is causal-ex-post facto research with data analysis using dynamic modeling systems. The results show that the water quality parameters tend to be stable, except for organic matter (51.82–115.02 mg/L). The semi-intensive shrimp farming system demonstrates relatively high harvest production, attributed to rapid shrimp growth despite limited feed management, resulting in profitable outcomes. Dynamic modeling reveals that increased biomass correlates with higher waste output, affecting the dissolved oxygen (DO) carrying capacity. Modeling also shows a moderate and fluctuating waste runoff pattern, indicating variable DO consumption. An important finding from this research is that we can control the water's carrying capacity for waste adsorption by determining the ideal cultivation system. The study concludes that DO carrying capacity follows a linear relationship with waste load; as waste increases, oxygen demand rises accordingly to support organic matter decomposition and ecosystem balance. These findings highlight the importance of managing waste to maintain optimal oxygen levels in semi-intensive systems. The conclusions of this research are important to be used as a source for coastal area management studies based on carrying capacity.
