本計畫透過收集相關文獻，以重新審視與建構魩鱙漁業之漁獲與生物學資料，並以臺灣西南枋寮海域鯷科稚魚之歷年cpue、努力量、魚種組成及環境因子變動分析等，嘗試進行CPUE標準化模式之建立，進一步建構剩餘生產量模式之運作模式(operating model)，再根據貝氏機率理論估計模式中各項參數之後驗機率分布進行參數求解，探討在大環境變動及持續不同的漁撈壓力等因素影響之下，評估臺灣週邊海域魩鱙之資源量、最適規模與總容許漁獲量，並根據模式中各項參數之後驗機率分布以模擬方法進行在各種不同漁獲控制策略下之之預測分析，以探討在大環境變動及持續不同的漁撈壓力等因素影響之下，評估該海域魩鱙之資源量、最適規模與總容許漁獲量 This study was tried to review and recreate the catch and bioparameter of anchovy fishery by using the historical references related to the larval anchovy population associated with the environment and other factors. In the following three year, the reachers will be to standarize the CPUE and to create one surplus reproduction model for evaluating the anchovy polulation and . Otherwise, Baye's probability theory was used to test posterior probability distribution and to simulate projection analysis for comparing the population variation and total allowable catches under the different fishing efficiency and environment。
