試驗分三個部份，試驗一酵母投餌量對文蛤成長之影響：取平均16.98mm、1.271g及肥滿度6.57%之文蛤苗，每三天投餌文蛤總體重0％、2％、4％、6％及8％等五組酵母菌，試驗結果在體長、總重及肥滿度均以6%組最好且顯著高於其餘各組。試驗二四種有機酸投餌量對文蛤成長之影響：取平均15.91 mm、1.028g及肥滿度7.08%之文蛤苗，每三天分別投餌文蛤總體重0、2％、4％、6％及8％之琥珀酸、丙氨酸、穀氨酸及檸檬酸，試驗結果，在殼長及重量，以2%丙氨酸及4%穀氨酸較佳，且顯著高於控制組；在肥滿度的表現上則以6%丙氨酸、6%琥珀酸、4%穀氨酸及6%檸檬酸較控制組佳；活存率在91.43-100%之間。試驗三酵母與有機酸添加量對文蛤成長交互之影響：取平均17.21mm、1.34g及肥滿度5.16%之文蛤苗，每三天分別投文蛤總重6%酵母、3%酵母、6%酵母+2%alanine、6%酵母+4%glutamic acid、3%酵母+2%alanine、3%酵母+4%glutamicacid等六組餌料，經30天飼育試驗結果：在殼長成長方面，以6%酵母+2%alanine 、6%酵母+4%glutamic acid 及3%酵母+2%alanine最好且顯著高於3%酵母投餵處理組。在重量增加方面級肥滿度方面，以6%酵母+2%alanine、6%酵母+4%glutamic acid 及3%酵母+2%alanine三組最好，且統計上高於其餘各組，其次為6%酵母及3%酵母+4%glutamicacid組，最差為3%酵母組，活存率表現由93.33-100%。

研究報告摘要(英) The experiment were divided three parts, the objective of the first experiment was to study the effects of different levels yeast on the growth in hard clam. The initial averages 16.98mm, 1.271g and the condition factor 6.57% of hard clams were used for the test .The test was divided five groups, 0%, 2%, 4%, 6% and 8% yeast s of total body weight in hard clam. The 6% yeast group was significantly higher than other groups in the shell, the weight and the condition factor on hard clam. The objective of the second experiment was to study the effects of different levels of four organic acid on the growth in hard clam.The initial averages 15.91 mm, 1.028g and the condition factor 7.08% of hard clam were used for this test. Every three days threw 0, 2%, 4%, 6% and 8% succinic acid, the alanine, the glutamic acid and the citric acid of total body weight in hard clam. The test results, in the shell length and the weight, 2% alanine and 4% glutamic acid were best and significantly higher than the control group. In the condition factor, the 6% alanine, 6% succinic acid, 4% glutamic acid and 6% citric acid compared the control group to be good; The survival rates were 91.43-100%. The objective of the third experiment was to study the cross effects with yeast and organic acid in hard clam. The initial averages 17.21mm, 1.34g and the the condition factor 5.16% of hard clams were used for the test. Every three days threw 6% yeast, 3% yeast, 6% yeast +2%alanine, 6% yeast +4%glutamic acid, 3% yeast +2%alanine, 3% yeast +4%glutamic acid of total body weight in hard clam. The test results after 30 days, in the shell length ,6% yeast +2%alanine, 6% yeast +4%glutamic acid and 3% yeast +2%alanine were best and significantly higher than 3% yeast group(control group). In the cweight and ondition factor, 6% yeast +2%alanine, 6% yeast +4%glutamic acid and 3% yeast +2%alanine were best and significantly higher than other each group, next was 6% yeast and 3% yeast +4%glutamicacid group, the worst was 3% yeast group, The survival rates were 93.33-100%..
