Effect of thermal challenge on the expression of genes involved in ovarian steroidogenesis in Tasmanian Atlantic salmon (Salmo salar)
Thermal challenge typically results in lowered plasma 17β-estradiol and 17,20β-dihydroxy-4-pregnen-3-one, and is associated with poor reproductive performance in commercially important female Atlantic salmon. The aim of the present study was to gauge the thermal sensitivity of genes crucial to ovari...
