中文摘要 | 研究自2006年1月2日至2006年11月20日止,進行1對白條海葵魚 ( Tomato anemonefish;Amphiprion frenatus)之生殖行為及幼苗之培育研究。研究期間共產卵 21 次;產卵間隔約 16.4 日,產卵時間在日間,主要集中在 10:10 ~ 14:30 ,生殖行為持續 1 小時左右;每次產卵數約 800 ~ 2,500 顆,受精卵為橘紅色、長橢圓形、分離之沉性黏著卵,受精卵之平均長徑為 2.70 ± 0.12 mm 、平均短徑為 0.96 ± 0.03 mm 、平均卵黃長徑為 1.75 ± 0.06 mm ;仔魚孵化平均體長為 4.48 ± 0.14 mm 。產卵結束後親魚有護卵行為,產卵到孵化期間雌雄護卵次數分別為 7.67 ± 2.40 及 56.92 ± 13.14 次∕30分鐘,護卵主要是由雄魚擔任。白條海葵魚胚胎孵化所需的時間與水溫成反比。仔魚孵化後第 7 天左右體色開始出現,並轉變為橘紅色,成長至第 9 天時體側即可明顯發現二條橫帶,此時可以與海葵共生而不會受到海葵攻擊。白條海葵魚仔魚初期餌料生物系列為輪蟲與橈腳類,添加微藻有穩定水質及滋養輪蟲之功效,餌料生物之提供應該注意各個餌料必須重疊使用。仔魚成長至 18 日左右開始可以接受人工飼料。在 260 日仔魚體長可達 55.57 ± 2.91 mm ,此時魚體色及斑紋已與成魚一致。 |
英文摘要 | Tomato anemonefish (Amphiprion frenatus) broodstock under artificial environment have ovulated 21 times, from January 2 to November 20, 2006. The average spawning intervals were 16.4 days on water temperature 24 ~ 30 ℃. The timing of spawning started from 09:20 to 17:30 with a peak from 10:10 to 14:30, and the spawning behavior lasted for an hour. About 800 ~ 2,500 eggs were released in each spawning. Those adhesive demersal eggs were reddish orange and oval with size about 2.65 ± 0.32 × 1.04 ± 0.07 mm (Mean ± SD). The yolks were about 1.97 ± 0.34 mm in length diameter and the newly hatched larvae were about 4.48 ± 0.17 mm in length. Parental care behaviors mainly carried out by males, for females and males 7.67 ± 2.40 times per 30 minutes and 56.92 ± 13.14 times per 30 minutes, respectively. The hatching time decreased with increasing water temperature. At 7th day post hatching (DPH), the body color of larvae turned to reddish orange. At 11th DPH the body appears 2 white streaks and symbiosis with sea anemones. Live feed for the initial larvae stage was rotifer and copepod. In addition, microalgae were added to stabilize water quality and to nourish rotifers. A fixed feeding time was applied. At the 18th DPH, pellet diet could be applied to the fry. The 260th DPH juvenile (55.57 ± 2.91 mm) has the same pattern of bands and color with adult. |
