Teaching semester

Spring

This course has a limited capacity, enrolment is based on application. Application deadline is Thursday in week 2 for the spring semester. Please see this page for more information: https://www.uib.no/en/matnat/53431/admission-courses-limited-capacity

You will receive confirmation of whether you received a spot in Studentweb no later than Tuesday the week after the deadline.

The time of the first lecture/orientation meeting can be found in the schedule on the course website or on the Mitt UiB learning platform.

The course runs only if enough students enrol.

It is mandatory to attend the first lecture.

Objectives and Content

The aim is to give an introduction to the basic principles of modelling natural fish populations and ecological communities to assist in solving management related questions. The most important population dynamic processes, such as growth, mortality and recruitment will be outlined, and how these interact among coexisting species in an ecosystem. The mathematical descriptions (models) and practical methods for parameter estimation and model fitting to data will be presented and discussed. In addition will the standard fish stock assessment models for abundance and yield estimation, and their underlying assumptions, be explained. Emphasis will be on a practical approach to the subject in form of exercises and applications, and how the results are used in fisheries management.

Learning Outcomes

The course provides a general introduction to the theory of fish population dynamics. Age, growth, natural and fishing mortality, maturation and recruitment concepts will be introduced together with mathematical tools for describing these processes. Classical fisheries stock assessment models for estimating yield and biological reference points for management purposes will be covered. Uncertainties in parameter estimation and critical evaluation of model assumptions will be emphasized. Both age based and length based approaches to individual models will be introduced. Effects of ecological factors together with fishery impact on biology, age at maturation, survival, growth and demography of populations will be discussed in order to link the student's ecological understanding to their theoretical tools.

Required Previous Knowledge

Compulsory courses in the Bachelor's programme in Biology or the Bachelor's programme in Sustainable Aquaculture (discontinued programme).

Recommended Previous Knowledge

BIO325 Ocean Science (20 ECTS) or MAR230/BIO240 (discontinued courses).

Compulsory Assignments and Attendance

  • Calculation exercises and other assignments.

Approved compulsory activites are valid for 3 semesters, including the semester of completion. All compulsory activities have to be approved in order for the student to take the exam.

Forms of Assessment

  • Oral exam, which accounts for 80% of total grade.
  • Assignments, which account for 20% of total grade.

Due to the measures taken to avoid the spread of SARS-CoV-2, UiB is closed for teaching and assessment. As a consequence, the following changes is made to assessment spring semester 2020:

  • Grading scale ¿Pass/Fail¿ instead of ¿A-F¿

Grading Scale

The grading scale used is A to F. Grade A is the highest passing grade, grade F is a fail.

Course Evaluation

Students will evaluate the course in accordance with the quality assurance system at UiB and the Department. You can find courseevaluations in the Quality Assurance Reports.
