Ikan yang bertindak sebagai pengimbas dalam pemijahan dengan metode Cangkringan adalah ikan mas. Ikan mas jantan yang disuntik ovaprim dapat memberikan pengaruh imbas pada pemijahan ikan tawes. Pengaruh imbas tersebut akan semakin kuat jika juga terdapat ikan mas betina sebagai pengimbas.
Perlakuan terbaik dihasilkan oleh perlakuan B (ikan mas ♂♂♀ disuntik) dan D
(ikan mas ♂♂♂ disuntik) dengan derajat pemijahan sebesar 66,7% dan fekunditas
telur berkisar antara 95.280-97.662 butir telur.
Saran
Perlu dilakukannya penelitian lanjutan untuk mengetahui organ yang melepaskan feromon pada ikan mas.
