Temperature induced changes in physiological traits and expression of selected candidate genes in black tiger shrimp (Penaeus monodon) larvae

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 seven candidate genes: three male determining genes, female genes a single thermal stress response gene) aspects black tiger shrimp (Penaeus monodon) larvae. treatments significantly altered growth individuals (P < 0.05) with highest obtained at 32?, moderate were 28?30? lowest remaining temperatures. shortened larval durations 28?, 30? (required 44–46 days for differentiation) while 52–63 required 24?, 26? 34?. also experimental P. monodon individuals; higher proportions males (coupled genes) lower temperatures (24? 26?) larger females (with (30?, 34?). gene, heat shock protein (HSP70) showed constant but other Results imply that can increase produce turn help improve aquaculture production.
