中文摘要 | 本研究自2012年3月17日至隔年3月24日止,針對一對配對成功的黑公子小丑種魚,觀察其產卵、孵化及胚胎發育,並進行仔魚培育試驗,同時探討其形態形質的變化。此期間觀察一對黑公子小丑共產卵23次,每次平均產卵數約500至1200粒,受精卵為橘黃色、橢圓形、分離之沉性附著卵,平均長徑為2.70 ± 0.12 mm,平均短徑為0. 96 ± 0.03 mm,平均卵黃徑為1.75 ± 0.06 mm,內含許多大小不一的油球,平均油球徑為0.13 ± 0.06 mm。在水溫27.2 ± 0.5℃,鹽度32 ~ 33 psu下孵化所需時間約為177小時,剛孵化之仔魚平均全長為4.31 ± 0.13 mm,並具趨光性,隨著成長,仔魚趨光性變弱。孵化後投予輪蟲 (Brachionus plicatilis) 為初期餌料,第5日起可兼投橈足類,第15日以後給予豐年蝦無節幼蟲,孵化後第25日,魚苗之平均全長為13.02 ± 1.78 mm,可開始接受人工粒狀飼料。 |
英文摘要 | A pair of artificially paired parent fish of Amphiprion ocellaris var. were observed from March 17, 2012, to March 24, 2013, for the spawning, hatching and larval development. Experimental larvae rearing and morphometric study were simultaneously conducted. During the study, the clownfish ovulated 23 times, and about 500 ~ 1200 eggs were produced each time. These adhesion demersal eggs were orange and ellipsoidal and were about 2.70 ± 0.12 mm long and 0. 96 ± 0.03 mm in diameter. The yolks were about 1.75 ± 0.06 mm long and contained several oil droplets of about 0.13 ± 0.06 mm in diameter. The larvae were reared at a water temperature of approximately 27.2 ± 0.5℃ for a required incubation time of 177 hours. The newly hatched larvae were about 4.31 ± 0.13 mm in total length and were also phototactic, although the phototaxis lessened as they grew. The larvae were fed with rotifers (Brachionus plicatilis) from day 1 post-hatching to 10 DPH. On 5 DPH copepod was added to the feeds and the amount added was increased gradually until it totally replaced rotifers on the 10th DPH. The 25 DPH larvae were about 13.02 ± 1.78 mm in total length and could begin to be fed with pellet feed. |
