Objectives

The course will provide the student with basic knowledge in the field of Aquaculture.



On completion of the course the student should, within each respective topic, be able to:

- describe the basic anatomy and physiology of our most common farmed fish species,

- critically review the most common aquaculture production systems,

- explain the fundamental nutritional needs of our most common aquaculture species,

- describe the pros and cons of present and future feed ingredients for farmed fish and the impact their properties have on feed production, feeding and fish performance, as well as their quality as food items,

- account for critical factors involved in the genetics and reproduction of our most common aquaculture species,

- describe how genetic breeding values are estimated for our most common aquaculture species,

- describe fundamental health and welfare factors of our most common aquaculture species.

Content

The course is divided into five thematic units.



1. Important aquaculture species and production systems. Background knowledge will be provided regarding the main aquaculture species including fish, shrimps, bivalves, other invertebrates and algae. Furthermore, we will present and explain the main aquaculture production systems and their respective pros and cons with regard to production and environmental impact.



2. Reproduction in aquaculture species. The course will provide information on the main reproductive strategies that we encounter in aquatic organisms that are relevant for aquaculture. Moreover, critical genetic, epigenetic, and environmental factors involved in reproductive physiology will be presented.



3. Aquaculture breeding and genetics. Through this course, the student will be introduced to common breeding schemes in aquaculture species including those aimed for release into natural environments. Introductory theory regarding the estimation of genetic parameters and breeding value estimation under aquaculture breeding schemes will presents. Additionally, modern genomic tools for aquaculture breeding purposes will be presented. The student will also gain practical experience using the R programming language for performing simple numerical calculations for breeding purposes. Computer exercises will be based on aquaculture datasets derived from traditional pedigree schemes as well as genomic information.



4. Aquaculture nutrition, feeding and feed technology: This thematic unit will provide students with an introduction to various feed ingredients, and their use in the formulation and production of aquafeeds. The main technologies used for aquafeed production will be presented. The course will address the nutritional impact of the ingredients on the growth performance, reproduction, health, and quality of farmed fish and shellfish. This involves learning about the digestive system of fish and shellfish, and the digestibility of various feed ingredients and nutrients. The course will also cover the antinutritional factors in feed and feed ingredients and their impact on the performance of the farmed aquatic animals as well as on the environment. Students will also learn about nutritional programming, alternative feed resources and nutraceuticals used in aquafeed, and the regulations that the food safety agency and the industry must deal with within this area. Hands-on training will be given to the students in assessing and using nutritional information, feed formulation and feeding, and the design of nutritional experiments.



5. Health and welfare: In the framework of this thematic unit, the students will be introduced to major infectious and non-infectious diseases affecting a wide variety of farmed fish and shellfish. This includes pathogenic microbial agents, such as bacteria, viruses, parasites, and fungi-like agents that threaten the health and well-being of these farmed animals. This module will also cover the issues of non-infectious diseases associated with extreme weather events and/or intensive aquaculture culture. Focus will be on infection control through preventive measures anomaly detection and sampling. Knowledge on health, welfare, and disease indicators as well as medical treatments are provided.





The teaching is in the form of online lectures and demonstrations of calculations, as well as laboratory exercises and study visits. This will be complemented discussions and answering questions online. There will also be own work and assignments to hand in.



Training in the following general competences are included in the course: problem solving, written communication.

Formats and requirements for examination

Passed written examination. Approved assignments. Participation in the online-discussions can give bonus points for the exam.

The online discussion meetings will also be used as a compliment examination form in addition to the written exams and assignments, which are also done online. The different formats of the examination include verbal discussions and written multiple choice.

• If the student fails a test, the examiner may give the student a supplementary assignment, provided this is possible and there is reason to do so.
• If the student has been granted special educational support because of a disability, the examiner has the right to offer the student an adapted test, or provide an alternative assessment.
• If changes are made to this course syllabus, or if the course is closed, SLU shall decide on transitional rules for examination of students admitted under this syllabus but who have not yet passed the course.
• For the examination of a degree project (independent project), the examiner may also allow the student to add supplemental information after the deadline. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.

Other information

• The right to take part in teaching and/or supervision only applies to the course date to which the student has been admitted and registered on.
• If there are special reasons, the student may take part in course components that require compulsory attendance at a later date. For more information on this, please refer to the regulations for education at Bachelor's and Master's level.

Additional information

All teaching within the course is given online.
