In open access model, the result shows that resources will face extinction crisis if the fishery is not controlled well. In present value maximization model, the albacore fishery would sustainable management. This result is valuable for the fishery management authorities to maintain the development of fishery and cherishing ocean resources at the same time.

最后，本文分别对开放式渔场模型及现值极大化模型进行模拟分析，模拟结果显示，开放式渔场若不稍加管制，其资源有可能面临灭绝的危机，而现值极大化模型在适度的捕捞下，将可使渔业永续经营，此结果可提供渔业管理者之参考，使其发展渔业的同时也能珍惜海洋资源。

As a whole,the notable characteristic of primary productivity in size-fractioned structure was that nanoplankton occupied comparatively significant advantage in Beibu Gulf.Nanoplankton has the largest contribution to gross primary productivity,and picoplankton was the secondary contributor,while microplankton the least.The contribution of microplankton for primary productivity in the north Gulf was more than that in the other waters.Nanoplankton and picoplankton contribute more to the gross primary productivity in offshore deep waters than in inshore shallow waters3.The Beibu Gulf can be divided into three ecoregions:Region-Ⅰis the ecoregion in inshore shallow waters of the north Gulf.In average,the water depth is 18m,DIN is 1.88μmol/L,DIP is 0.20μmol/L,N:P is 9.4:1,dissolved silicate is 5.17μmol/L,the Chl a conentration in surface layer is 2.27mg·m~(-3),the assimilation index in surface layer is 3.80mg/,the primary productivity is 198.78mgC/(m~2·d), and potential fishery production is estimated to be 0.24gC/(m~2·a) according to the primary productivity.The ecoregion is mainly affected by the northern coastal water systems,and may be fit for aquaculture;Region-Ⅱis the ecoregion in offshore deep waters of the north Gulf and the coastal shallow waters to the west Hainan Island.In average,the water depth is 35m,DIN is 2.01μmol/L,DIP is 0.18μmol/L,N:P is 11.2:1,disovled silicate is 4.23μmol/L,the chlorophyll a of surface layer concentration is 1.45mg·m~(-3),the assimilation index of surface layer is 4.12 mg/,the primary productivity is 276.60mgC/(m~2·d),and the estimated potential fishery production is 0.34gC/(m~2·a) according to the primary productivity. The ecoregion was mainly influenced by ocean current from the South China Sea, rivers in the west coast of Hainan Island and the water from Qiongzhou Strait.It may be fit for aquaculture and fishery;Region-Ⅲis the ecoregion in offshore deep waters of the mid and south Gulf.In average,the water depth is 75m,DIN is 0.77μmol/L, DIP is 0.15μmol/L,N:P is 5.1:1,disovled silicate is 3.05μmol/L,the chlorophyll a of surface layer concentration is 0.70mg·m~(-3),the assimilation index of surface layer averaged is 3.69mg/,the primary productivity is 350.89mgC/(m~2·d),and the estimated potential fishery production is 0.43gC/(m~2·a) according to the primary productivity.The ecoregion was mainly affected by the circulation inside Beibu Gulf, and may be fit for fishery.

初级生产力的粒级结构的一个显著特点是总体上微型浮游生物在全调查海区均占较明显优势，对总初级生产力的平均贡献最大；微微型浮游生物对初级生产力的平均贡献次之；小型浮游生物对总初级生产力的平均贡献最小；湾北部小型浮游生物对初级生产力的平均贡献高于湾中部和湾南部，而湾中部和湾南部微型和微微型浮游生物对初级生产力的平均贡献高于湾北部，远岸深水区高于近岸浅水区。3、北部湾可以分为三个生态区：湾北部近岸浅水区，该区的环境主要特点是平均水深19m，DIN浓度平均值为1.88μmol/L，DIP浓度平均值为0.20μmol/L，N：P为9.4：1，硅酸盐浓度平均值为5.17μmol/L，表层叶绿素a平均值高达2.27 mg·m~(-3)，表层同化指数平均为3.80 mg/，初级生产力平均值198.78mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.24 gC/(m~2·a)，该区主要受湾北部沿岸水系影响，适合作为水产养殖区；湾北部深水区和海南岛西部沿岸浅水区，该区的环境主要特点是平均水深35m，DIN浓度平均值为2.01μmol/L，DIP浓度平均值为0.18μmol/L，N：P为11.2：1，硅酸盐浓度平均值为4.23μmol/L，表层叶绿素a平均值1.45 mg·m~(-3)，表层同化指数平均为4.12mg/，初级生产力平均值276.60 mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.34 gC/(m~2·a)，该区主要受南部湾口区海流向湾内延伸，沿岸海南岛河流注入湾内和琼州海峡过道水的影响，适合作为渔业作业区和水产养殖区；湾中部和南部远岸深水区，该区的环境主要特点是平均水深75m，DIN浓度平均值为0.77μmol/L，DIP浓度平均值为0.15μmol/L，N：P为5.1：1，硅酸盐浓度平均值为3.05μmol/L，表层叶绿素a平均值0.70 mg·m~(-3)，表层同化指数平均为3.69 mg/，初级生产力平均值350.89 mgC/(m~2·d)，根据初级生产力计算潜在渔业资源碳生产量平均为0.43 gC/(m~2·a)，该区主要受北部湾环流影响，适合作为渔业作业区。

The fishery ports herein refer to manmade or natural ports designated to serve fishery production, provide moorage and avoidance of winds for fishery ships, handling fishery harvests and supplement materials for fishery, including special fishery docks, special fishery water areas and special anchorage sites for fishery ships in comprehensive ports.

前款所称渔业港口，是指专门为渔业生产服务、供渔业船舶停泊、避风、装卸渔获物、补充渔需物资的人工港口或者自然港湾，包括综合性港口中渔业专用的码头、渔业专用的水域和渔船专用的锚地。

Two types of Overfishing are mentioned in fishery industry management; one is the Biological Overfishing which is due to overfish catches of fish by human beings, the other is Economic Overfishing, which is due to the excessive investment of fishery equipment from fisherman. Both types of Overfishing could cause the serious damage of fisherman who depends on the fishery resources.

渔业经营管理中有两种过渔，一种是人类过渡捕捞渔获造成的『生物性的过渔』，另一种是则是渔民对软硬体设备过度投资而造成的『经济性的过渔』，不论何种型态的过渔危机都会让以海为生的渔民蒙受其害。

Study the management of the marine fishery risk just from the financial tool angle can\'t also bag all contents of risk management, from the marine fishery risk management of inside request to set out, need to study the non-financial tool that the Chinese marine fishery risk manages, such as the quarter rest fishing system, developing ecosystem fishery, developing the high and new technique of the marine fishery,, construct the risk information of the marine fishery management system, develop to lie organization etc. in the marine fishery.

仅从金融工具角度研究海洋渔业风险管理还无法囊括风险管理的全部内容，从海洋渔业风险管理的内在要求出发，需研究中国海洋渔业风险管理的非金融工具，如伏季休渔制度，发展生态渔业，发展海洋渔业高新技术，建设海洋渔业风险信息管理系统，发展海洋渔业中介组织等。

Before its appearance most of the fishery disputes were conciliated through fishery regulative and administrative agencies. Due to the lack of binding force, the conciliation suffers a low performing rate. Fishery disputes that cover different sea areas were usually delayed in resolution because neither party concerned had confidence in the fishery regulative and administrative agency of the other party.

该特别规定出台的背景是：渔业争议大多标的小；大部分通过渔政渔港监督管理部门行政调解解决，但由于行政调解没有强制执行力，行政调解结果履行率较低；跨海区的渔业争议，由于争议双方对对方所在地的渔政渔港监督管理部门不信任，往往争议久拖不决。
