| Planning Group on Data Needs for Assessment and Advice (PGDATA) | PGDATA helps ICES and other end users to understand the quality of datasets and to use them as effectively as possible, and to employ objective ways to identify and prioritize data needs. |
| Stock Identification Methods Working Group (SIMWG) | This group reviews new methods for the definition and investigation of stock structure and provides advice to other ICES expert groups on how to interpret patterns of population structure. |
| Working Group on Biological Parameters (WGBIOP) | This Working Group is devoted to the provision of biological parameters at a national, regional, and stock level, serving as a bridge between data collectors and end users. |
| STECF | |
| Expert Working Groups on the EU Data Collection Framework (DCF) | EU expert working groups on the Data Collection Framework (DCF), e.g. for the evaluation of the DCF work plans and annual reports. |
