Learning outcomes
|
Course aims are provide fundamental knowledge about culture of crayfish and other crustaceans, which represent an important diversification in aquaculture. Partial aims are: 1) Introduction to the crayfish environmental requirements, methods of catching and diseases. 2) Presentation of main methods of astaciculture in the Czech Republic and abroad (ranging from extensive to intensive). 3) Excursion to the crayfish farm (shoving culture management under practical conditions) and nature localities. 4) Give information about culture methods and aquaculture potential of further crustaceans (shrimps, crabs, lobsters and spiny lobsters).
The graduates will achieve the basic knowledge in the field of biology, protection and culture of crayfish and the most important native and non-native molluscs of the Czech Republic. They obtain practical abilities in determination of target crayfish and mollusc species. Students will be able to realize rescue transfers of endangered species or eradication of invasive once.
