中文摘要 | 為探討紅甘�閰韞芫犎u節前,在室內水泥池培育對成熟及誘導產卵的可行性,將18尾2齡之種魚於生殖季節前約 4 個月,自海上箱網移入陸上室內水泥池,純以下雜魚投餵種魚。結果發現,種魚於室內池子之攝餌、成長及生殖腺的發育均相當正常,但種魚於生殖期間,攝餌率低下,成長遲滯。生殖季節時,每間隔2週以人類胎盤絨毛激素注射全部的種魚,劑量為0.5 ± 0.1 IU╱g,結果在5次的注射中,有4次成功誘導產卵,產卵的水溫範圍為21.5-25.5℃,鹽度為33.7-35.1 ppt。產卵時機一般開始發生於注射後36-40小時間,每次產卵持續3-5日。3月13日至5月10日生殖期間,總計採獲261萬粒卵,浮上卵的比率佔50.25%。 |
英文摘要 | In order to study the possibilities of maturation and induced spawning of indoor pond-tamed purplish amberjack Seriola dumerili, eighteen 2-year-old spawners were transferred into indor concrete pond from October 30, 1996. They were fed only with trash fishes 5-6 times weekly. Results showed that the feeding activity, growth and gonadal development were similar to those seacage-farmed amberjack. From beginning of breeding season, the total spawners were received an injection of human chorionic hormone (HCG) every 2 week. Four occasions were succeeded to induce spawning among 5 trials. Spawnings were occurred at water temperature of 21.6℃ to 25.5℃ and salinity of 33.7 ppt to 35.1 ppt. Spawnings occurred commonly 36-40 h after the hormonal treatment and lasted for 3-5 days. In breeding season of March 13 to May 10, sixteen spawning days and 2.61 millions eggs were obtained. The buoyant rate of the total collected eggs was 50.25%. |
