Strategies for Water Management in Shrimp Mariculture: A Case Study of Kedongkelor Village, Pemalang Regency

Water quality plays a crucial role in the success of shrimp mariculture. This study aimed to evaluate the relationship between key water quality parameters and the growth performance and survival of shrimp in four mariculture ponds. Environmental variables, including temperature, salinity, dissolved oxygen (DO), and pH. Results showed that temperature fluctuated between 26–31 °C, salinity ranged from 26.5–33 ppt, DO concentrations varied from 4.7 to 8.3 mg/L, and pH levels were stable between 7.3 and 8.2. Optimal evening temperature and DO levels did not show a consistent correlation with improvements in Average Daily Growth (ADG), Average Body Weight (ABW), or Survival Rate (SR). Pond 2, located closer to the water treatment reservoir, exhibited the highest growth performance and survival, highlighting the importance of water quality management. Conversely, Pond 3 showed reduced SR due to high stocking density and improper water management practices. Biosecurity measures, such as chlorine application and pond lining with High-Density Polyethylene (HDPE), were implemented but require further efforts to prevent pathogen intrusion. The study emphasizes the critical need for continuous water quality monitoring, proper water circulation, and enhanced biosecurity strategies to support best shrimp farming production. Maintaining stable environmental conditions within optimal ranges can enhance shrimp growth, and survival, ultimately improving mariculture productivity.
