  • Understanding and manipulating fish sexual development is essential for sustainable aquaculture.

Purpose of the Study:

  • To review methods for controlling sex determination in cultured fish.
  • To discuss applications of these techniques in major aquaculture species.
  • To explore endocrinological approaches for managing fish reproduction.

Main Methods:

  • Review of scientific literature on fish sex determination and reproduction control.

  • Analysis of techniques for producing all-male, all-female, and sterile fish populations.
  • Examination of endocrinological methods for reproductive management in aquaculture.

    • Main Results:

    • Various methods exist for controlling sex determination in fish, enabling targeted population production.
    • Techniques for producing monosex (all-male or all-female) and sterile fish are applicable to key aquaculture species.
    • Endocrinological strategies offer further control over fish reproductive cycles.

    Conclusions:

    • Effective control of sexual development is vital for advancing aquaculture productivity and efficiency.
    • The reviewed methods provide tools for genetic improvement and population management in cultured fish.
    • Further research into reproductive endocrinology can optimize aquaculture practices.
