水產研究(1993年創刊)-條石鯛胚胎發育與育苗研究
主題: 條石鯛胚胎發育與育苗研究
摘要(中):
本研究旨在探討條石鯛 (Oplegnathus fasciatus) 之繁殖技術開發。利用深層海水調控水溫,順利誘發條石鯛種魚自然產卵。受精卵為分離、球形之浮性透明卵,平均卵徑為0.86 ± 0.05 mm;平均油球徑為0.12 ± 0.01 mm,受精卵在水溫24 ± 1 ℃下,約25 h孵化,剛孵化之魚苗平均全長為2.93 ± 0.02 mm。第 3 日齡仔魚平均全長為 3.16 ± 0.12 mm,開始投餵小型輪蟲,並添加微藻來穩定水質及滋養輪蟲。第7日齡平均全長為3.94 ± 0.14 mm,此時仔魚攝食能力增強,可混投橈足類,同時餌料生物之提供應該注意各種餌料必須重疊使用。第23日齡仔魚平均全長為7.64 ± 1.33 mm,此時已可以接受人工飼料。第40日齡幼魚平均全長為 33.58 ± 6.28 mm,此時之體色及斑紋已與成魚一致。

摘要abstract(英): This study was aimed at establishing the artificial propagation techniques of Rock porgy (Oplegnathus fasciatus) in Taiwan. Broodstock are induced to spawn with temperature-regulated deep sea water that pumped from a depth of 637 m. The fertilized eggs of the fish are buoyant and semi-transparent, with an average diameter of 0.86 ± 0.05 mm (Mean ± SD), and contained a single oil globule which was 0.12 ± 0.01 mm in diameter. These eggs hatched at 25 h after fertilization (Temp. = 24 ± 1°C; sal. = 32 ~ 33 psu). The newly hatched larvae were about 2.93 ± 0.02 mm in total length. The larvae (3.61 ± 0.12 mm) were fed with rotifers (Brachionus plicatilis) from the 3rd day post hatching (DPH). Adding microalgae (Tetraselmis chui) can stabilize water quality and nourish rotifers. The 7 DPH fry were about 3.94 ± 0.14 mm in total length, and copepods were used as feeds instead. Two different sizes of live feeds should be applied during the transitional period. The 23 DPH fry were about 7.64 ± 1.33 mm in total length and could be fed pellet diet. The band and color patterns of the 40 DPH juveniles (33.58 ± 6.28 mm) were similar to those of the adult fish.
