Course content
|
The course will be presented in the form of an intensive mini-course and practical exercises. Main topics of the course will be: 1) Current production problems in the Czech Republic and the importance of RAS technology 2) History of RAS, advantages and disadvantages of using RAS in practice 3) Design of recirculation systems for aquaculture 4) Mechanical filtration - construction and principles 5) Biological filtration - theory, calculations of biological filtration capacity, filter run-in, influence of water quality on biological filtration 6) Biological filtration - construction and advantages of individual biological filters 7) Disinfection (ozone or UV), oxygenation and heating 8) Basic terminology - recirculating aquaculture systems 9) Water quality - fish requirements and values in the RAS, including its measurement 10) Types of breeding tanks - hydraulics and construction 11) Operating principles RAS 12) Health control, prevention, preventive baths and quarantine in intensive farms Practice: 1) Practical operation of individual RAS components 2) Measurement and maintenance of high water quality in RAS 3) Sorting and handling of farmed fish in RAS

Learning outcomes
|
The aim of the course is to provide students comprehensive information on the technology of recirculating aquaculture systems (RAS), including its history and gradual technological development. Thanks to this course, students will obtain theoretical and practical knowledge and experience with the operation of various types of RAS, including information on the design, function and maintenance of individual RAS components. After graduation of the course, students will be able to operate with RAS technology. In addition, students will know the parameters of individual technological components, according to which components are selected and connected to the RAS. The aim of the course is to expand theoretical and practical expertise that will help to use the systems in practical production aquaculture and scientific practice in order to diversify aquaculture and increase its production.
Graduates of this course will be able to design, effectively operate and use a functional RAS for the aquaculture of various high valuable fish species.
