中文摘要 | 本論文之目的是研究在藍刻齒雀鯛 (Blue devil, Chrysiptera cyanea) 之人工繁殖技術,以應觀賞魚產業之需求。研究發現,藍刻齒雀鯛受精卵呈淡白色至淡黃色,為長橢圓形、分離之沉性黏著卵,受精卵之平均長徑為 1.19 ± 0.03 mm (平均長 ± 標準偏差);短徑為 0.60 ± 0.01 mm;卵黃長徑為 0.61 ± 0.05 mm,內有許多油球,油球徑 0.02 ~ 0.18 mm。仔魚孵化全長為 2.80 ± 0.2 mm。親魚會有護卵行為,主要是由雄魚擔任。在水溫 25 ± 1 ℃ 時,約 102 小時後開始孵化。初期餌料生物為纖毛蟲、輪蟲及橈腳類,並添加微藻來穩定水質及滋養輪蟲,同時餌料生物之提供應該注意各個餌料必須重疊使用。受精卵在不同鹽度下之孵化率有顯著差異 (p < 0.05),以鹽度 20 psu之孵化率達 97.5% 為最高,而 0 及 5 psu 組之受精卵沒有孵化。胚胎孵化後之畸形率與鹽度成負相關變化,鹽度在 10 psu 畸形率為 12.5%,32 psu 則未發現有畸形之仔魚。 |
英文摘要 | This study was aimed to understand the reproductive behavior, larval culture under artificial environment of Blue Devil (Chrysiptera cyanea) and other relevant phenomenon. Eggs were adhesive and demersal with color white to yellow. They were ellipsoidal, and were about 1.19 ± 0.03 mm (Mean ± SD) in total length and 0.60 ± 0.01 mm in width. The yolks were about 0.61± 0.05 mm long and contained several oil droplets with diameters ranging from 0.02 to 0.18 mm. The newly hatched larvae were about 2.80 ± 0.20 mm in length. Parental care behaviors for the ovum occurred from spawning to hatching. The parental behavior was mainly carried out by males. Incubation period was approximately 102 h at the water temperature of 25 ± 1 ℃. The living feeds for Blue Devil at initial larvae stage was ciliate, rotifer and copepod. Microalgae were added to stabilize water quality and to nourish rotifers. Hatching rate of fertilized eggs varied significantly with salinity. Hatching rate was the highest (97.5%) at 32 psu, but hatching failed at salinities ranging from 0 to 5 psu. The abnormal rate was an inverse ratio to salinity. Abnormal rate of hatched larvae was the highest (12.5%) at 10 psu. The abnormal rate was 0 when hatching salinity was 32 psu. |
