人工魚礁漁業效益調查及可行性評估 (101)

年度 2012
計劃名稱 人工魚礁漁業效益調查及可行性評估
中文摘要 本年度計畫預定進行澎湖海域人工魚礁區基礎資料及生物資料調查。其間共規劃調查鎖港、香爐嶼、澎南、錠鉤嶼、內垵北海域、望安與七美東南等7個魚礁區調查,以及3處臺灣周邊海域待設魚礁區(地點尚待主管單位指示辦理)的可行性評估。調查時將應用側掃聲納、都卜勒水深剖面儀、防水相機等等,以取得高品質的數據。 預期效益: (1) 蒐集上述各魚礁區之海底地形測繪、礁體側掃、底質、流速流向、礁體附著生物相、礁區魚類相與生物量和魚礁經濟效益調查與評估。 (2) 收集上述前7個魚礁區內之網具覆網之現況,並提供覆網清除之建議。 (3) 根據所收集到之魚礁區各項資料,評估魚礁區效益的良窳,並做成繼續投礁與否之建議。 (4) 調查評估上述各人工魚礁區經濟面、海洋生態面及社會面之效益,以作為日後管理決策之依據。 (5) 針對漁民或漁會所提之新設魚礁區需求,評估該區域劃定人工魚礁區之可行性,並提出建議。 (6) 針對全期計畫所得資料,提擬通盤檢討的建議。
英文摘要 In this year basic information and biological data will be collected on artificial reefs (ARs) in waters off Penhu islands. The AR sites to be studied include Suo-Gang, Xiang-Lu Islet, Peng-Nan, Ding-Gou Islet, Nei-An North, Wang-An and Qi-Mei Southeast, and 3 to-be-decided new sites in waters off Taiwan. A variety of equipments, including a side-scanner, an ADCP (Acoustic Doppler Current Profiler), water-resistant cameras, etc., are used in the survey to obtain high quality data. The fulfillment of this project would be expected to bring about: 1) an understanding of the present status of marine environmental factors such as water depth, underwater topography, substratum types, the distance  between AR and natural reefs, AR dispersion, and biomass of the inhabiting biota for each AR site. 2) recommendations on whether cast-net removal should be made to each specific AR site based on the data collected. 3) recommendations on whether each of the above specific AR site should be maintained or terminated based on the present status of the ARs. 4) evaluations on the effectiveness of these AR sites from the economical, marine ecological and social points of view. The findings are expected to be involved in the decision-making for the future AR management. 5) evaluations on the feasibility of new-site establishment. 6) an overall review of the current status of the artificial reef program.
