中文摘要 | 文蛤養殖模式可概分為:直接施撒粉料、抽取有機發酵液及抽取藻水等三種給餌之方式;平均養成期約為12.8個月。三種不同養殖模式之經營成本以抽取藻水者最高,抽取有機發酵液者最低;經營利潤則以直接施撒魚粉者最高,抽取有機發酵液者最低。但整體而言,文蛤養殖業經營仍有利潤。進一步以財務分析方法評估各種養殖模式之經營效率,可發現三種模式中以直接施撒粉料者最高,抽取有機發酵液者因投資成本較少,雖然其收益與利潤最低,但投資報酬仍高於抽取藻水模式。 |
英文摘要 | The survey data categorized, based on the feeding of hard clam, Meretrix lusoria, into (1) fishmeal, (2) organic fermentive water and (3) algae water. The averaged grow out period was approximant 12.8 months. Analysis of the survey data showed that a fed algae water diet group had the highest total costs, whereas the fed fishmeal diet group had the highest returns per hectare among three groups. As a result, hard clam culture still had some profits. In regard to the production efficiency, the study found that fed fishmeal diet group had the highest investment efficiency. |
