Sex reversal induced by 17β-estradiol may be achieved by regulating the neuroendocrine system of the Pacific white shrimp Penaeus vannamei.

ABSTRACT:

Background

Due to sexual dimorphism in growth of penaeid shrimp, all-female cultivation is desirable for the aquaculture industry. 17β-estradiol (E2) has the potential to induce the male-to-female sex reversal of decapod species. However, the mechanisms behind it remain poorly understood. This study aimed to investigate the effects of E2 immersion on the neuroendocrine system (the eyestalk ganglia, brain, thoracic ganglia, and ventral nerve cord) of the Pacific white shrimp Penaeus vannamei through comparative transcriptomic analyses of the control males (CM), E2-treated males without sex reversal (EM), and neo-females (NF).

Results

Immersion in E2 at 2 mg/l from post-larvae (PL) 5 to 85 results in a skewed female-to-male ratio of 2.56: 1. The survival rate remains unaffecte
