Introduction to Stock Assessment

This course provides introduction, demonstration, and exercises in population modelling as applied to fishery resources

21 – 25 February 2022
Online course

Registration is closed.


The general objective of the course is to train scientists in basic population dynamics and stock assessment. The course not only presents the theoretical elements but also puts theory into practice through case studies and hands-on exercises.

Specific objectives are:

  1. understanding the role of stock assessment in fishery science
  2. familiarity with conventional stock assessment models
  3. experience in basic model building and parameter estimation
By the end of the course, the participants will:
  • be aware of single species assessment methods as applied to North Atlantic fisheries
  • understand the data-collection needs for different assessment methods
  • be familiar with indicators and reference points, both biological and economic, as tools in fishery management
  • develop knowledge of population and fishery processes by using simulation models to improve scientific advice for managers


This is a 5-day online course, consisting of online sessions and intersessional exercises. The course is organized over Microsoft Teams. ​

All live sessions will take place within European office hours, but if needed can be recorded to accommodate attendance for participants in different time zones according to ICES Training Course recording policy.


The course provides a conceptual understanding, supported by quantitative applications that are designed to illustrate model properties. Advanced topics and programming skills will be introduced in preparation for more advanced ICES courses or to approach the same topics through self-learning.

Requirements for attending

Participants should have basic knowledge of R and Excel. 

​​​ICES Training Course recording policy

ICES might record live sessions of the training course. The purpose of the recording is to allow course participants to re-watch the material and should not replace participation in the lectures, unless previously agreed upon. It will be accessible to course participants, instructors and ICES staff for two weeks from the final day of the training course. ICES staff, training course instructors and participants presenting material in a recording must ensure that they do not infringe third-party copyright. You may not record the training course yourself without obtaining the consent of both ICES Secretariat and course instructors. If you do not wish to be recorded, please do not turn on your web camera and write your questions to the instructors via email.
