| 中文摘要： |
| 本研究基於B-H模型創建了一種多魚種管理方法，即把針對單魚種的“開捕年齡”和“捕撈死亡係數”管理目標替換成面對多魚種的“開捕網目尺寸”和“捕撈努力量”管理目標，從而實現多魚種管理。利用文獻參數，對東海兩種主要經濟魚種帶魚和小黃魚的綜合管理進行了嘗試和探討。結果顯示，帶魚和小黃魚由於體型和個體大小差距較大，最適產量重疊範圍較小，兩個魚種不適宜綜合管理；可以針對不同漁場、不同專捕漁船進行單獨管理。該模型具直觀、易判、及時等優點；同時存在短期有效、要求體形相近等缺點。若要推廣該模型，需要積累足够的基礎數據以獲取必要的模型參數；另外還需要探討捕撈努力量標準化方法，進一步提高模型準確性。 |
| 英文摘要： |
| B-H model，a single-species management model，is not suitable for multi-species coexistence situation due to several limitations.In this paper，a multi-species management approach is created based on B-H model by replacing“catchable age”and“fishing mortality”of single species management model with“catchable mesh size”and“fishing effort”of multi-species management model to achieve multi-species management objective.The multi-species management approach was used to test with the two typical species of the East China Sea，hairtail and small yellow croaker based on literatures.The big differences in body shape and body size between hairtail and small yellow croaker and the small optimum yield overlapping area demonstrated that these two species are not suitable for the integrated management，which should be managed separately by different fishing areas or different fishing vessels.This model has merits like intuitive，easy-judging and timely but with limitations of short-term effectiveness and similar shape requirements.To promote the application of this multi-species management approach，it needs to further accumulate various basic data for the relevant elementary parameters，standardize fishing efforts and explore ways to improve the model accuracy. |
