中文摘要 | 本調查提供本省草蝦養殖業者在爆發蝦病後之養殖經營者類型、經營方式、經營成本與所得,及簡述本產業之前途與展望,以作為養殖業者之經營參考。經分析資料後發現,每公頃草蝦平均放養密度為35萬尾,養殖戶放養之蝦苗分成紅筋與黑殼兩種規格,且放養時間是以三至五月為主,養殖期維持在四至五個月間。養殖場以小規模之0.1-1.0公頃範圍最多,家庭成員為勞力來源。養殖管理者以低學歷高年齡及中高學歷中年齡兩種類型為主。草蝦養殖疾病仍以白斑病為主,而且業者於放養過程均以調降鹽度至千分之十左右來減輕病變。本次調查有46%可養成至可收獲上市之大小,其平均活存率為38%。每公頃草蝦養殖場經營成本約為53萬元,平均收益為84萬元,平均本益比及所得率分別為57.19%及36.39%。 |
英文摘要 | The main purpose of this investigation was to provide the characteristics of manager and management, production costs and returns, industrial prospects under the prawn disease were threatening for the cultivator. Based on analyzing data, the prawn fry stocking density was 350 thousand per hectare, the fry was stocked by two larval stage of p10-15 and p25-30. The major breeding season beginning from March to May and through rearing period of 4-5 months for harvesting. The pond area from 0.1 to 1 hectare small size was the almost. Family members provided the labor. The characteristics of two groups of operators were elder with little years of formal education and middle age with more years of formal education. The WSBV infections of prawn were the main disease. The salinity of rearing water was commonly controlled in 10 ppt to reduce susceptibility of prawn disease. There were 46% of farms of prawns grow up to market size, the average of survival rate was 38%. The average production cost and benefit were NT$530,000 and NT$840,000 per hectare, the ration of net returns to total costs and gross returns were 57.19 and 36.39, respectively. |
