Abstract
Rasbora aprotaenia is one of the native fish of Indonesia that is distributed in the western part of Java Island. The fish is used for local consumption. Research efforts on rearing and breeding R. aprotaenia have been conducted at the Aquaculture Laboratory, University of Sultan Ageng Tirtayasa (Untirta). Research activities begin with the acclimatization and adaptation of prospective broodstock from nature and the use of gonadotropin hormones for gonad maturation. The next step is to carry out spawning. One of the hormones that can be used is ovaprim. The research aims to analyze the success of ovulation and the reproductive quality of female broodstock R. aprotaenia, which were given ovaprim at different doses. The study was conducted from September to October 2024 at the Aquaculture Laboratory, Untirta. The treatment used was injection of ovaprim hormone (mL/kg fish) for females at doses of 0.3, 0.5, 0.7, and without the addition of ovaprim. All males were injected with 0.5 ml/kg of ovaprim. The injection was done intramuscularly. The results showed that administration of ovaprim could induce ovulation in R. aprotaenia, while females without hormone administration failed to ovulate. The use of a dose of 0.5 ml/kg gave the best results, namely 100% ovulation with a latency time of 9 hours 3 minutes, fecundity of 95±24 eggs, egg fertilization rate of 44±8.64%, and larval survival rate on the seventh day 91±4.48%. The success of artificial spawning in this study can be used as a basis for mass production of R. aprotaenia.

| Additional Information: | Rasbora aprotaenia adalah salah satu ikan asli Indonesia yang tersebar di Pulau Jawa bagian barat. Serangkaian riset upaya budidaya R. aprotaenia telah dilakukan di Laboratorium Budidaya Perikanan, Universitas Sultan Ageng Tirtayasa (Untirta). Kegiatan riset dimulai dari aklimatisasi dan adaptasi calon induk dari alam, serta penggunaan hormon gonadotropin untuk pematangan gonad. Langkah selanjutnya adalah melakukan pemijahan. Salah satu hormon yang dapat digunakan adalah ovaprim. Tujuan riset adalah menganalisis keberhasilan ovulasi dan kualitas reproduksi induk betina R. aprotaenia yang berikan ovaprim dengan dosis berbeda. Penelitian dilakukan pada September sampai Oktober 2024 di Laboratorium Budidaya Perikanan, Untirta. Perlakuan yang digunakan adalah penyuntikan hormon ovaprim (mL/kg ikan) untuk betina dengan dosis 0,3; 0,5; 0,7; dan tanpa penambahan ovaprim. Hasil penelitian menunjukkan bahwa pemberian ovaprim dapat menginduksi ovulasi pada R. aprotaenia, sedangkan betina tanpa pemberian hormon tidak berhasil ovulasi. Penggunaan dosis 0,5 ml/kg memberikan hasil terbaik yaitu 100% ovulasi dengan waktu latensi 9 jam 6 menit, fekunditas 95±24 telur, tingkat pembuahan telur 44±8,64%, tingkat penetasan telur 73±7,30%, tingkat kelangsungan hidup larva sebelum kuning telur habis 92±3,16%, dan tingkat kelangsungan hidup larva setelah kuning telur habis 91±4,48%. | |||||||||
