Analysis of Water Quality Correlation with the Immune Response of Litopenaeus vannamei in Probolinggo, East Java
Summary
Researchers examined correlations between water quality parameters (temperature, pH, dissolved oxygen, salinity) and immune response indicators in whiteleg shrimp farmed across three ponds in Probolinggo, East Java, finding specific parameters strongly predicted immune function.
Whiteleg shrimp (Litopenaeus vannamei) is a major aquaculture commodity in Indonesia, valued for its resilience, rapid growth, and economic potential. However, water quality remains a critical factor influencing shrimp health, particularly their immune response. This study aimed to examine the correlation between water quality parameters and the immune responses of L. vannamei cultivated in Probolinggo, East Java. A descriptive quantitative method was employed, using simple random sampling across three pond sites. Water parameters measured included temperature, pH, dissolved oxygen (DO), salinity, ammonia, nitrate, total suspended solids (TSS), and total dissolved solids (TDS). Immune response indicators such as Total Hemocyte Count (THC), differential hemocyte count (DHC), and phagocytic activity were analyzed. Canonical Correspondence Analysis (CCA) was used to assess correlations. The results revealed significant relationships between water quality and shrimp immune parameters, highlighting the importance of proper environmental management in shrimp farming. These findings provide insights for improving productivity and disease resistance in sustainable aquaculture systems.

Diversity of phytoplankton in the whiteleg (Litopenaeus vannamei) shrimp ponds in the south coastal area of Pangandaran, Indonesia
This Indonesian study assessed phytoplankton diversity and water quality in shrimp ponds using different farming intensities, finding that phytoplankton community composition serves as a useful bioindicator of pond health and productivity. Healthy aquaculture ecosystems are relevant to food safety given that farmed seafood is increasingly being found to contain microplastics from contaminated water.
Evaluating the performance of Pacific white shrimp ( Penaeus vannamei Boone, 1931) reared under different stocking densities: a study of their biochemical, immune, metabolic and antioxidant responses in a biofloc aquaculture system
This study evaluated how different stocking densities affect growth performance, hemolymph biochemistry, immune indices, and antioxidant enzyme activities in Pacific white shrimp raised in biofloc systems, providing guidance for optimizing intensive aquaculture conditions.
Insight into the immune and microbial response of the white-leg shrimp Litopenaeus vannamei to microplastics
Researchers exposed white-leg shrimp (Litopenaeus vannamei) to different concentrations of microplastics for 48 hours and measured immune and microbial responses. The study found that high microplastic concentrations significantly reduced survival rates, altered immune-related gene expression, and disrupted the gut microbial community, suggesting that microplastic pollution may compromise shrimp immune function.
