Abstract
Oryzias woworae (Adrianichtidae) or Daisy's ricefish has an endemic distribution in the fresh waters of Muna Island, Southeast Sulawesi. Fulfilling the demand for O. woworae fish still relies on catches from nature so that the population has decreased drastically. High market demand has led to over-exploitation of its natural habitat, so that O. woworae has experienced a population decline and is under threat of extinction. This study aims to examine the reproduction performance of O. woworae using natural and cultivated broodstocks of the 3rd offspring. This is a experimental research that was conducted from November until December 2022. The parameters observed in this study is spawning behavior, egg of number, egg diameter, yolk volume, hatching rate, survival and total larvae, and water quality. Analysis of spawning behavior and water quality were analyzed descriptively. Data analysis on egg number, egg diameter, yolk volume, hatching rate, survival and total larvae were analyzed using analysis of variance (ANOVA). Spawning O. woworae on natural and cultivated broodstock has egg-releasing behavior between noon and evening. Production of O. woworae fish larvae can be done by crossing natural male and cultivated female broodstocks, as well as natural male and natural female broodstocks, which produce a total of 65‒74 eggs, egg diameter 1.37‒1.39 mm, yolk volume 0.61‒0.72 mm3 , hatching rate 65.05‒79.01%, survival rate 62.40‒83.75%, and total larvae 36‒43 individuals.

| Additional Information: | Oryzias woworae (Adrianichthyidae) atau yang sering disebut dengan Daisy’s ricefish merupakan ikan endemik perairan Pulau Muna, Sulawesi Tenggara. Pemenuhan permintaan ikan O. woworae masih mengandalkan tangkapan dari alam sehingga populasinya menurun drastis. Permintaan pasar yang tinggi membuat terjadinya eksploitasi berlebihan di habitat aslinya, sehingga O. woworae mengalami penurunan populasi dan masuk ke dalam ancaman kepunahan. Penelitian ini bertujuan untuk mengkaji performa reproduksi O. woworae menggunakan induk dari alam dan hasil budidaya keturunan ke-3. Penelitian ini bersifat eksperimental yang telah dilaksanakan pada November sampai Desember 2022. Parameter yang diamati pada penelitian ini yaitu tingkah laku pemijahan, jumlah telur, diameter telur, volume kuning telur, tingkat penetasan telur, sintasan dan total larva, dan kualitas air. Analisis tingkah laku pemijahan dan kualitas air dianalisis secara deskriptif. Analisis data jumlah telur, diameter telur, volume kuning telur, tingkat penetasan telur, sintasan dan total larva dianalisis dengan menggunakan analisis ragam (ANOVA) berdasarkan model rancangan acak lengkap (RAL). Pemijahan ikan O. woworae pada induk alam dan budidaya memiliki tingkah laku mengeluarkan telur antara siang sampai sore hari. Produksi larva ikan O. woworae dapat dilakukan dengan mengawinkan induk jantan alam dan betina budidaya, serta induk jantan alam dan betina alam, yang menghasilkan total telur 65‒74 butir, diameter telur 1,37‒1,39 mm, volume kuning telur 0,61‒0,72 mm3, tingkat penetasan telur 65,05‒79,01%, sintasan larva 62,40‒83,75%, dan total larva 36‒43 ekor. | |||||||||
