水產研究(1993年創刊)-棘頰海葵魚之生殖行為及初期發育
主題: 棘頰海葵魚之生殖行為及初期發育
摘要(中):
棘頰海葵魚 (Spine-cheek anemonefish, Premnas biaculeatus Bloch, 1790) 屬雀鯛科 (Pomacentridae) 海葵魚亞科 (Amphiprioninae)。本研究期間自2009年1月1日至12月31日止總計365日,觀察產卵25次,每次產卵數約800至3000顆,受精卵為橘紅色、橢圓形、分離之沉性附著卵,平均長徑為1.81 ± 0.09 mm,平均短徑為0.79 ± 0.03 mm,平均卵黃徑為1.25 ± 0.09 mm,內含許多大小不一的油球,平均油球徑為0.16 ± 0.03 mm。在水溫27.7 ± 0.8 ℃,鹽度32.5 ± 0.5 psu下孵化所需時間為144小時,剛孵化之仔魚平均全長為3.64 ± 0.31 mm,並具驅光性,隨著成長,仔魚趨光性變弱。孵化後1 ~ 6日投予輪蟲 (Brachionus plicatilis),第7日起可兼投橈足類 (Copepod),第10日以後完全給予豐年蝦,孵化後第20日,魚苗之平均全長為8.60 ± 1.04 mm,可開始接受人工粒狀飼料。

摘要abstract(英): Spinecheek anemonefish (Premnas biaculeatus) belongs to the subfamily Amphiprioninae of family Pomacentridae. During 365 days of observations from January 01 to December 31, 2009, the clownfish ovulated 25 times and produced 800 ~ 3000 eggs each time. These adhesive demersal eggs were orange with ellipsoidal in shape, and were 1.81 ± 0.09 mm long and 0.79 ± 0.03 mm in diameter. The yolks were about 1.25 ± 0.09 mm long and contained several oil droplets were 0.16 ± 0.03 mm in diameters. It took 144 hours to hatch as sea water was controlled at 27.7 ± 0.8 °C and 32.5 ± 0.5 psu. The newly hatched larvae were 3.64 ± 0.31 mm in total length and phototactic. The phototaxis lessened as they grew. Larvae were fed with rotifers (Brachionus plicatilis) from one to six days post-hatch (DPH). On seven DPH, copepod was supplemented and its amount was gradually increased until it totally replaced rotifers on 10 DPH. On 20 DPH, larvae were 8.24 ± 0.76 mm in total length and could be fed with pellet feed.
