Course Objective

The aim of the course is to teach the contemporary knowledge and methods on appraisal of the marine fisheries resources. The course will also include instruction sessions on how to use personal computer statistical packages for some applications of current stock assessment procedures.

Learning Outcomes of the Course Unit

1   Recognize the need for appraisal and assessment of marine fisheries resources.
2   Recognize the need for sampling design and statistical analysis for evaluation of marine fisheries resources.
3   Demonstrate understanding of fishing equipment and methods, their selectivity, direct and indirect consequences for marine fish populations and habitats.
4   Discuss critically the fundamental concepts used in appraisal and assessment of fish stocks.
5   Demonstrate an ability to design experiments, sampling programs or research surveys for evaluation of marine fisheries resources.
6   Analyse data for evaluation of marine fisheries resources with certain statistical software (R Project for Statistical Computing) and interpret results.
7   Demonstrate critical thinking skills in evaluation of their own research work and/or that of other researchers.
8   Communicate and discuss results from research projects and their implications with others in written and verbal forms.

Planned Learning Activities and Teaching Methods

1. Lectures
Class lectures are carried out in a highly interactive format. The instructor prompts students for response to questions posed and solicits their thoughts on issues discussed. Lectures will focus on the real world applications, and additional elaboration and illustration will be provided for better comprehension.
2. Class Discussions
In-class assignments and homework assignments are the basis of problems to be solved in classroom discussions. Individual participation by students in classroom discussions will be strongly encouraged.
3. Computer Applications
The statistical software R will be introduced to perform analyses of data and to produce graphics.
