Water quality and water treatment in aquaculture
The course will give students fundamental competence in chemistry with focus on water chemistry, water
treatement and environmental requirements of fish in aquaculture.
After completed course, the student is expected to possess the following knowledge, skills and general competence:
Knowledge:
- Develop basic knowledge about chemical processes in water, describe and calculate these by using formulas and fundamental chemistry knowledge
- Understand the environmental requirements of fish related to species and life stage, as well as the connections between water chemistry, physiology and biology
- Know the most common water treatment technologies and be able to calculate effect and dimensioning
- Know governmental water quality limits and discuss these in context of fish welfare and performance
Skills:
- Be able to balance chemical equations and determine what type of chemical reaction that occurs (acid-base, redox, precipitation reactions)
- Be able to calculate the distribution of ammonia: ammonium at given pH, temperature and salinity conditions
- Be able to calculate needed volumes/additions of commonly used chemicals, as well as aeration capacity/time and solubility of gases under given environmental conditions
- Assess and calculate whether specific production conditions would result in chronic or acute water quality issues
- Be able to calculate release of nitrogen, phosphorous and organic material from aquaculture, describe the environmental effects and have knowledge about common treatment methods
General competence:
- Has insight in relevant issues regarding water quality and water treatment in aquaculture
- Communicate core science and knowledge regarding water quality and water treatment in aquaculture
- Exchange points of view and experience with peers and contribute to development of best practice
Lectures, discussion groups, laboratory exercises. Course responsible emphasizes use of several learning methods
where students in different ways participate actively in the teaching.
- Compound assessment, grading scale Letter grades
- Compulsory participation, comprises 0/100 of the grade, grading scale Approved/ Not approved.
- Assessment Task, comprises 0/100 of the grade, grading scale Approved/ Not approved.
- Written examination, 4 hours, comprises 100/100 of the grade, grading scale Letter grades.
Compulsory participation in teaching groups.
Mappe (MA) of 6 elements, where 5 need to be passed for approval of the course:
- 2 Multiple choice examinations
