- W1755366253 abstract "<p>Water temperature could affect the reproduction of broodstock and sex ratio of progeny. In this study, broodstock of guppy (<em>Poecilia reticulata</em> Peters) was reared in different temperature to determine its effect on reproduction of broodstock and sex ratio of their progeny. The result of study show that broodstock reared at 27°C produced more fry (16 males mean) than that of 30°C (10 males), while broodstock reared at 33°C produced no progeny. Percentage of male fish produced by broodstock reared at 30°C is higher than that of 27°C. Incubation time of embryo before birth is sorter in broodstock reared at 30°C (4-12 days) compared with 27°C (18-22 days). However, several progeny of broodstock reared at 30°C had abnormal vertebrae.</p> <p>Keywords: guppy, <em>Poecilia reticulata</em>, sex reversal, reproduction, monosex</p> <p> </p> <p>ABSTRAK</p> <p>Suhu air inkubasi diduga dapat mempengaruhi reproduksi induk ikan dan nisbah kelamin keturunannya. Pada penelitian ini, induk ikan gapi (<em>Poecilia reticulata</em> Peters) dipelihara pada suhu 27°C, 30°C dan suhu 33°C untuk mengetahui pengaruhnya terhadap reproduksi dan rasio kelamin keturunannya. Hasil penelitian menunjukkan bahwa induk ikan gapi yang dipelihara pada suhu 27°C menghasilkan anak lebih banyak (rata-rata 16 ekor) daripada di suhu 30°C (10 ekor), sementara induk gagal melahirkan pada suhu pemeliharaan 33°C. Proporsi anak jantan yang dihasilkan oleh induk yang dipelihara pada suhu 30°C lebih banyak dibandingkan pada suhu 27°C. Waktu inkubasi embrio sebelum dilahirkan oleh induk yang dipelihara pada suhu 30°C lebih singkat, yaitu 4-12 hari, dibandingkan pada suhu 27°C, 18-22 hari. Namun demikian beberapa anak ikan yang lahir dari induk yang dipelihara pada suhu suhu 30°C mengalami abnormalitas pada bagian tulang belakangnya. </p> <p>Kata kunci: ikan gapi, <em>Poecilia reticulata</em>, <em>sex reversal</em>, reproduksi, monoseks</p>" @default.
