Immune Response of White Shrimp (Litopenaeus vannamei) to Different Density and IMNV Challenge

Highlight ResearchWhite shrimp (Litopenaeus vannamei) challenged with IMNV and different stocking densitiesThe water quality parameter values are getting worse along the increase in densityWhite THC value decreased increasing density challenge testThe development of increased an seen from speed percentage appearance clinical symptoms histopathology results AbstractIncreasing affects physiology behaviour their moving space. The health condition is influenced by feeding, growth, its susceptibility on disease. aim this study was to determine immune response relation presence infection. This used a completely randomized design (CRD) at 100 shrimp.m-2, 200 400 three replications each treatment. 5,02±0,26 g virus infection exposed orally. research facilitated Disease Research Centre Laboratory Central Proteina Prima Company, Pasar Kemis, Tangerang for 30 days. showed that Total Hemocyte Count (THC) hemolymph had between negative controls IMNV. lowest found m-2 (3.00x106ml-1). While highest shrimp.m-2 (4.75x106ml-1). result supported parameters shrimp. Histopathology changes skeletal muscle lymphoid organs confirmed faster high densities.
