NWSJEMS Ecopath with Ecosim Model

This Ecopath with Ecosim (EwE) model was developed for the North West Shelf and the food web upon which it is based. The fishery of the area has been variable over the years. Bulman attempts to capture the trophic flows and biomasses during the late 1980s. At this time, the foreign fishery had reduced considerably following closures and the domestic fisheries were expanding. Fifteen years of catch and effort data were used to tune the model, i.e., annual fishing effort data were input in order to try to recreate the actual changes in the system caused by fishing.

本生态通道与生态模拟（Ecopath with Ecosim，EwE）模型专为西北陆架（North West Shelf）及其依存的食物网开发。该区域的渔业活动多年来波动不定。Bulman旨在还原20世纪80年代末的营养级流动与生物量状态。彼时，外国捕捞船队因禁渔措施大幅缩减作业规模，而国内渔业正处于扩张阶段。研究采用十五年的渔获量与捕捞努力量数据对模型进行校准，即通过输入年度捕捞努力量数据，以期复现捕捞活动对该系统造成的实际变化。
