Temperature is an important abiotic factor influencing growth, development, metabolic performance and sex determination of aquatic organisms. The present study was conducted to test the effect six different temperature levels (24?, 26?, 28? as control, 30?, 32? 34?) on physiological (growth, developmental durations, survivability, ratios O2 consumption) genetic (changes in expression pattern se...

The susceptibility of Macrobrachium idella, M. lamerrae and M. rosenbergii to white spot Ž . syndrome virus WSSV was tested by immersion challenge, oral route and intramuscular injection. Their susceptibility to WSSV was compared with that of Penaeus indicus and P. monodon. The WSSV caused 43.3% and 53.3% mortality in M. lamerrae and M. idella, respectively, by immersion method and 53.3% and 66...

The black tiger shrimp (Penaeus monodon) is an ecologically and economically important penaeid species and is widely distributed in the Indo-Pacific region. Here we investigated the genetic diversity of P. monodon (n = 355) from eight geographical regions by genotyping at 10 microsatellite loci. The average observed heterozygosity at various loci ranged from 0.638 to 0.743, indicating a high le...

Abstract This review summarises the current knowledge of mineral nutrition for penaeid shrimp. It investigates how aquatic environment and lifecycle shrimp affect requirements role that minerals play in health. Methods supplying via either water or to feed, novel ways supplementing within are discussed. The individual summarised with recommendations minimum levels dietary inclusion semi‐intensi...

DNA-based molecular markers for differentiation of five penaeid shrimps (Penaeus monodon, P. semisulcatus, Feneropenaeus merguiensis, Litopenaeus vannamei and Marsupenaeus japonicus) were developed based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-stranded conformation polymorphism (SSCP) of 16S ribosomal (r) DNA. Differentiation of P. monodon, P....
