本計畫之目的為執行象牙鳳螺及硨磲貝之種原採集及蓄養，探討其於人為環境下產卵機制。採卵成功後繼續研究孵化及幼生培育技術，研究受精卵發育及孵化機制、幼生餌料及培育方法，建立種苗生產技術。第一個試驗：建立野生及人工象牙鳳螺種原蓄養保存方式，野生及人工培育象牙鳳螺不同年齡產卵試驗結果，產卵期從3月21日至9月15日 止，產卵高峰在5月至9月。野生2008年組：平均每槽所產卵鞘數2,100 ± 416個；野生2007年組：平均每槽所產卵鞘數3,667 ± 219個；野生2006年組：平均每槽所產卵鞘數5,331 ± 385個；野生2005年組平均每槽所產卵鞘數4,210 ± 580個；野生2004年組平均每槽所產卵鞘數2,597 ± 894個；人工二齡年組平均每槽所產卵鞘數2,288 ± 62個；人工三齡年組平均每槽所產卵鞘數3,566 ± 332個；人工四齡年組平均每槽所產卵鞘數3,831 ± 392個。試驗結果：野生2006年組為最佳與其他各組有差異，其次為野生2005年、人工4齡、野生2007年及人工3齡，四組間無差異而與其他組間有差異，接著為野生2004年、人工2齡及野生2008年，三組間無差異而與其他組間有差異(p<0.05)。試驗中也瞭解不同年齡野生及人工種螺在人工蓄養環境下產卵模式亦可做為人工繁殖量產之基礎，經3次育苗試驗成功培育出131萬粒之仔螺。第二個試驗：自澎湖海域收集硨磲貝種貝共37顆，其中長硨磲貝33顆（佔89.19％），鱗硨磲貝4顆（佔10.81％）。長硨磲貝外套膜共生藻顏色可區分成褐、綠及藍3個顏色，以褐色24顆（佔72.73％）最多，其次為綠色8顆（佔24.24％），以藍色1顆（佔3.03％）最少；鱗硨磲貝外套膜共生藻顏色僅有褐色1種。長硨磲貝平均殼長22.5±3.1㎝，殼長分布18.1-29.3㎝；鱗硨磲貝平均殼長24.2±5.9㎝，殼長分布18.8-30.3㎝。硨磲貝之採集必須以潛水進行，因此作業及運輸難度頗高，本今度共活存25顆（佔67.57％）。長硨磲貝活存22顆，佔長硨磲貝採集數的66.67％；鱗硨磲貝活存3顆，佔鱗硨磲貝採集數的75.00％。

研究報告摘要(英) The objectives of this study are establishment of genetic stock and cultural techniques of Babylonia areolata, and giant clams , Tridacna maxima and T. squamosa,. The genetic stock will be collected and preserved for utilization of researchers. The tank system, diet, growth, mature size, spawning season, embryonic development, hatching, and larvae rearing will be studies. The knowledge will be very valuable for the mass seed production. In the first experiment, this plan was set up both wild and artificial spawners of B. areolata stocked techniques for genetic stock. Babylonia areolata’s spawning season is form March to September, and high peak period is from May to September. Results of various stocked age on B. areolata of group of 2006 wild spawners with average total egg capsules were 5,331 ± 385 was the best than others (p<0.01). There were no differences in total egg capsules among those 4 groups, 2005 wild spawners with average total egg capsules were 4,210 ± 580, artificial spawners (4-year old) spawned 3,831 ± 392, 2007 wild spawners spawned 3,667 ± 219 and artificial spawners (3-year old) spawned 3,566 ± 332. capsules. However those 3 groups of 2004 wild spawners spawned 2,597 ± 894 capsules, artificial spawners (2-year old) spawned 2,288 ±62 and 2008 wild spawners spawned 2,100 ± 416 capsules were of no difference among each other, but were lower than other 5 groups. Understanding that various stocked age of wild and artificial spawners’ spawning behavior in indoors provided us to produce mass seed. It was also succeed in cultivating 1.31 million juveniles of B. areolata . In the second experiment, there are 37 giant clams collected from Penghu, including Tridacna maxima is 33 and T. squamosa is 4 inds. The mantle color of T. maxima has 3 patterns are brown, green and blue. Brown is 24 inds （72.73％） more than green（8 inds, 24.24％）and blue（1 inds, 3.03％）. But T. squamosa has only one color is brown. The average of shell length in T. maxima is 22.50 ± 3.06 ㎝, from 18.1 to 29.3㎝, and T. squamosa is 24.23 ± 5.92 ㎝, from 18.8-30.3 ㎝. The survival inds is 25（67.57％）because it’s difficult to keep alive throughout sampling and transporting with scuba diving. And the survival inds of T. maxima sample is 22（66.67％）, T. squamosa is 3（75.00％）.
