无脊椎动物资源管理中指标的使用是在鱼类渔业更广泛应用的背景下进行的。如果没有充分的评估，根据下降幅度和趋势分析为《濒危物种国际贸易公约》提出的指标是适当的。考虑到年龄结构和库存-招募关系很少可用，衡量生殖业绩经常建立在每次招募卵子的考虑之上。将从模型得出的参考点与直接使用数据序列进行比较，并建议采用提供指标冗余的一刀切方法。指标可以衡量生产力以及生物量和开采率，但生态系统、空间、生境、环境特征和社会经济考虑因素也需要监测。有必要将多种指标和参考点纳入收获规则和其他决策基础设施。各种驾驶方式……
The use of indicators in management of invertebrate resources is placed in the context provided by more extensive applications in finfish fisheries. Indicators proposed for the Convention on International Trade in Endangered Species based on extent-of-decline and trend analysis are appropriate should full assessments be unavailable. Measuring reproductive performance frequently builds on egg-per-recruit considerations, given that age structure and stock–recruit relationships are rarely available. Reference points derived from models are compared with direct use of data series, and a broad-brush approach providing a redundancy of indicators is recommended. Indicators may measure productivity as well as biomass and exploitation rate, but ecosystem, spatial, habitat, environmental characteristics, and socio economic considerations also require monitoring. There is a need to integrate multiple indicators and limit reference points into harvest rules and other decisional infrastructures. The various driving fo...
