In a number of marine animals, sperm serine proteases are important for fertilization. Penaeus monodon sperm require trypsin-like activity for a complete acrosome reaction, which exclusively occurs in sperm residing in the female thelycum. In this study, a complete cDNA sequence of reproductive tract-related Serine protease inhibitor (rrPmserpin) was identified.

Article Synopsis
- Dietary polyunsaturated fatty acids (PUFAs) are essential for ovarian development in the black tiger shrimp (Penaeus monodon), where they are stored in the hepatopancreas and contribute to energy and yolk formation.
- Research identified 8-hydroxyeicosapentaenoic acid (8-HEPE) in the shrimp's hepatopancreas, suggesting that its production depends on the activity of lipoxygenase (LOX) enzymes.
- Analysis showed that as the shrimp's ovaries mature, the expression of PmLOX increases while the levels of 8-HEPE and PmLOX in the hepatopancreas decrease, indicating differing needs for fatty acid biosynthesis during ovarian development stages
We exploited Artemia as a double-stranded (ds)RNA-delivery system to combat viral diseases in shrimp. First, the transformed Escherichia coli (E. coli) expressing red fluorescent protein (RFP) was tested in the Artemia enrichment process.

Here, we describe the successful oral application of dsRNA targeting Laem-Singh Virus (LSNV) to diminish monodon slow growth syndrome (MSGS) in Thai Penaeus monodon. Shrimp feed formulated with bacterially expressed LSNV-dsRNA was given to shrimp for 9 weeks.
