Feminisasi dapat dilakukan dengan memanfaatkan ekstrak daun kemangi (Ocimum sanctum L) karena mengandung fitoestrogen alami. Penelitian selama 3 bulan di Workshop Pembenihan Ikan Fakultas Perikanan dan Kelautan Universitas PGRI Palembang Laboratorium Biologi Sains Teknologi Palembang. menggunakan metode Rancangan Acak Lengkap 6 taraf perlakuan ulangan 0,5, 10, 20, 40, 80 mg/L. diperoleh hasil perendaman pada menghasilkan persentase tertinggi P4 (40mg/L) sebesar 85%. Pertambahan bobot yang optimal 0,66 g, pertambahan panjang 2,37 cm, sedangkan kelangsungan dipelihara 30 hari 96,66%, disimpulkan memberikan efek signifikan dalam setiap parameter pengamatan.AbstractThe decline in the population of female kissing gouramy is currently needed efforts to support pursued survival fish through feminization techniques.
