在印度洋工作组内，对开发的海洋生态系统的评估有几个步骤，从简单的生态系统二元分类到更复杂的尝试，对它们进行排名，并使用决策树分析来评估它们的状况。为了向公众和利益攸关方传播科学知识，重点是利用一套六项生态指标和一个简单透明的生态系统状况图示（饼图），评价和比较已开发海洋生态系统的状况。出现的一个问题是，使用一套通用指标来比较不同类型的海洋生态系统是否可以接受。为此目的，试图提供可以客观地比较生态系统的参考水平。每项指标不可接受的阈值是根据向一组科学专家分发的调查表中得出的生态专门知识确定的。对调查问卷的分析显示，为不同生态系统类型提供的阈值没有显著差异，这表明使用选定的一套指标直接比较不同类型生态系统的国家是合理的。
Within the IndiSeas WG, the evaluation of exploited marine ecosystems has several steps, from simple binary categorization of ecosystems to a more-complex attempt to rank them and to evaluate their status using decision-tree analyses. With the intention of communicating scientific knowledge to the public and stakeholders, focus is on evaluating and comparing the status of exploited marine ecosystems using a set of six ecological indicators and a simple and transparent graphic representation of ecosystem state (pie charts). A question that arose was whether it was acceptable to compare different types of marine ecosystems using a generic set of indicators. To this end, an attempt is made to provide reference levels to which ecosystems can be objectively compared. Unacceptable thresholds for each indicator are determined based on ecological expertise derived from a questionnaire distributed to a group of scientific experts. Analysis of the questionnaires revealed no significant difference in the thresholds provided for different ecosystem types, suggesting that it was reasonable to compare states directly across different types of ecosystem using the set of indicators selected.
