一.文蛤源頭管理及養殖模式之建立文蛤源頭管理是應用危害分析與重要管制點（HACCP ）的觀念導入文蛤養殖過程，從種苗來源、水源、底土、飼料四方面著手，將不利文蛤成長及活存的因素管控好，改良養殖物及養殖管理，創造良好的成長環境，促進養殖物的成長及活存率。而底質改善對文蛤養成效果之影響試驗可以達到改善池塘底質及促進文蛤成長速率及活存率的目的。二.單體牡蠣之育肥及貯藏技術研發本試驗之目的在於研發單體牡蠣收成後育肥與衛生處理及衛生處理後最適貯藏條件，生產高品質之台灣生蠔，以提升本國牡蠣之競爭力。試驗育肥效果反應於貝殼內軟體肉質部之肥滿度，比較牡蠣不同餌料育肥對其牡蠣肥滿度、體成份、肝糖、風味、高度不飽和脂肪酸、牛磺酸之變化。並將經肥育後之單體牡蠣以經1微米過濾後再經臭氧處理後之海水流水式絕食蓄養，經24小時後，再定上述經衛生處理後之單體牡蠣分別置於5℃-30℃貯存30天，貯存過程中，分別採樣進行化學、鮮度、衛生細菌、總細菌含量之變化。三.文蛤池進行蝦類箱網養殖系統之建立在文蛤田間養殖池中裝設魚蝦養殖箱網，或在文蛤池中另開挖小面積飼料池，內可裝設魚蝦養殖箱網，替代目前普遍使用衛生條件不確定之肥水發酵池，小面積飼料池中若未裝設魚蝦養殖箱網，亦可以網槽方式養殖魚蝦，確保小面積飼料池中魚蝦成長良好，作為衛生與水質條件良好之指標生物。魚蝦用飼料使用自動投餌機定時定量投餌，控制小面積飼料池水固定透明度範圍，視大面積文蛤養殖池飼料需求量，額外添加較廉價之粉狀配合飼料，使用粉液自動混合抽出裝置，定時定量注入小面積飼料池。文蛤養殖池中亦可另外使用粉液自動混合抽出裝置，添加更微量之高價位粉狀配合飼料，達成文蛤田間養殖源頭管理之目標預期效益：建立塭養文蛤源頭管理養殖模式，降低文蛤池有機肥料與一般飼料之使用量，減緩池底之老化，提高文蛤外殼之鮮亮度及殼內肉質部之肥滿度。評估指標：(一)期中審查標準：完成文蛤養殖前之各項設施設備裝設，並進入初期養殖。(二)期末審查標準：完成大型粉液自動混合抽出裝置之最適定時定量測試及改良，文蛤養殖進入中末期。四.上市文蛤物流管理模式之建立透過本研究建立產品品牌，提昇產品形象，開拓市場通路與直銷管道。並探討優質文蛤消費者願付價格，以訂定產品價格。

The basic management of hard clam culture is applied the idea of HACCP into thepracticed procedures. It will be discussed how to control the effective factor of growthand survival rate, Including seeds, water source, sediment and feeds.The objection of thisyear are to improve conditions of sediment during rearing period and increase growthand survival rate of hard clam.The second purpose of this experiment is to develop an pre-market rearing ,depurationsystem and optimal storage condition for oysters to produce excellent taiwan oyster thatcould be enhance global competition of oyster in Taiwan. This study examines theeffects of bivalve short-term stock rearing on the growth of soft inside their shell. Theexperiment oysters are reared in tank with different diets. The oysters are feed ondifferent diets to compare their somatic composition and taste, unsaturated fatty acid,taurine. Bacterial flora and coliform in the oysters soft be counted by many interval ofexperiment period that the oyster rear in continuously-flowing seawater for 24 hourswithout any food is supplied. The flowing seawater be filtered to 1 um filters andsterilized by different doses ozone .The change in Biochemical analyses,freshnessquality,sanitary bacterial and total bacterial in oyster meat during storage from 5 ℃ to30℃.The thrid purpose of this experiment is an auto-feeding feeder of shrimp would beimproved from fish auto-feeder or be developed a new type that could scatter pellet feedevenly overall cage water body that would be fit to feeding behavior of white shrimp innet cage.The equipments for installing net cage grow-out system of white shrimp in hardclam pond would be established its construction mode that optimum efficiency could beachieved.The shrimp and hard clam production system would be developed andbecome a source inventory control mode of hard clam grow-out in pond.The amount offeed and organic fertilizer that put in hard clam pond would be reduced. The acidifyingof pond sediment would be slowed down.The clam would be have its brilliant outer shelland the soft inside its shell be growing full.The growth and survival rate of shrimp inhard clam pond would be arise and appendant income of clam farmer be increasedFirnal purpose of this experiment is to promote the hard clam marker and image. It willhelp to expand market passageways. On the other hand, we will confer consumerperception and willingness-to-pay for hard clam production, in order to decide the price.
