本試驗主要目的是探討飼料中不同含量酵母菌、光合菌及螺旋藻對文蛤成長之影響，試驗飼料分10組分別為對照組、飼料添加1、3、5 ％酵母菌組、添加1、3、5 ％ 光合菌組及添加1、3、5 ％螺旋藻組，試驗取平均 19.37 mm及1.84 g 之文蛤苗，每三天投餌文蛤總體重2％之粉狀飼料，試驗為期80天，試驗結果在殼長增加方面以 5% 螺旋藻及 1%光合菌添加組較高，且顯著高於其餘各組，其次為3%酵母菌及5%光合菌添加組，最差為3%光合菌及對照組。在重量增加方面以 5% 螺旋藻添加組顯著高於其餘各組，其次為1%光合菌組及3%酵母菌添加組，最差為對照組且顯著低於各組。在肥滿度的表現上以3%、5% 酵母菌、5%螺旋藻添加組顯著高於其餘各組，其次為1、3、5%光合菌組，最差為1、3%螺旋藻組、1%酵母菌組及對照組。活存率表現由92.38-100%，且各組間無顯著差異。

The objectives of this study were to investigate the effects of the different content of yeast, photosynthetic bacteria and spirulina in dietary on the growth in hard clam. The test dietary divided into ten groups were the control group, added 1,3,5% yeast groups, added 1,3 , 5% photosynthetic bacteria groups and added 1,3,5% spirulina groups. The initial averages 19.37 mm and 1.84 g of hard clams were used for the test. Every three days threw 2% dietary of total body weight in hard clam for 80 days. The test resulted in shell length, 5% spirulina and 1% photosynthetic bacteria groups were best and significantly higher than other groups, followed by 3% yeast and 5% of photosynthetic bacteria groups, the worst were 3% photosynthetic bacteria and the control groups. In weight increases, the 5% spirulina group was significantly higher than other groups, followed by 1% of photosynthetic bacteria and 3% yeast groups, the control group was the worst and significantly lower than other groups. In the condition factor, 3% yeast, 5% yeast and 5% spirulina groups were significantly higher than other groups, followed by 1,3,5% Photosynthetic Bacteria Group, the worst were 1% spirulina,3% spirulina, 1% yeast and control groups. The survival rates were from 92.38% to 100%, and no significant difference among groups.
