1. Knowledge of theoretical concepts used in stock assessment of commercially exploited marine living resources;
2. Understanding of the main theoretical models, their basic assumptions and approximations needed data and estimation methodologies parameters.
3. To carry out the assessment of the state of a fishery resource, using basic tools developed in the classe and formulate advice for their conservation and management

The classes are organized into modules and each module are taught the theoretical and practical contents. Theory complemented with solving practical exercises. Whenever possible, students should also solve worksheets at home. The theoretical content will be transmitted to students based on classroom lessons, expository nature using dynamic visual presentations. For practical classes will use a set of worksheets per module performed mostly in Excel.
Classes should be given theoretical and practical regime. For each module there is a set of practical worksheets to solve in class and at home and still optional worksheets to settle out of class. The worksheets will be wherever possible resolved and corrected in class.
