Eels (Anguilla spp.) exhibit complex life cycles and face challenges such as habitat loss and overexploitation, necessitating innovative approaches to enhance their reproductive success and growth. The primary objective of this study is to explore genomic and developmental methods to improve eel reproduction and growth, with a focus on understanding the underlying biological mechanisms and identifying strategies for aquaculture improvements. Recent research has highlighted several key findings. In Japanese eel (Anguilla japonica), androgen regulation has been shown to significantly influence ovarian growth and follicle development. In European eel (Anguilla anguilla), recombinant gonadotropins can effectively induce spermatogenesis and sperm release, improving reproductive outcomes. Additionally, studies have revealed complex relationships between growth rates and environmental factors such as temperature, which affect eel development over time. The expression of gonadotropin subunits and receptors during different stages of oogenesis has also been characterized, providing insights into the hormonal regulation of reproduction. These findings underscore the potential of genomic and developmental approaches to enhance eel reproductive success and growth. By leveraging hormonal regulation, recombinant gonadotropins, and understanding environmental influences, significant advancements can be made in eel aquaculture. These strategies not only improve reproductive efficiency but also contribute to the conservation and sustainable management of eel populations.
