Tingkat reproduksi yang tinggi menyebabkan terjadinya pematangan gonad sebelum mencapai ukuran produksi dimana hal tersebut dapat merugikan pembudidaya, karena saat ikan mengalami matang gonad energi hasil asimilasi pakan sebagain besar akan dialokasikan untuk perkembangan gonad dan menghambat pertumbuhan somatik. Pemanfaatan senyawa aktif dari bahan alami biji pepaya dapat menjadi solusi untuk meningkatkan pertumbuhan ikan yang dibudidayakan sekaligus menjaga keamanan pangan dan konsumen.
