Learning outcomes

Knowledge:
The present course allows the student to obtain knowledge about aquaria and fish farms management, the equipment, element cycles in the tanks, knowledge about the most important fish species, reproductive strategies, the importance of phyto and zooplankton in aquaculture, as well as deeper knowledge about the embryonic and larval development of fish. 

Ability to apply the knowledge:
the student will aquire the following skills: aquaria and tanks management, performing chemical-physical tests.

Soft skills:
Laboratory activities, as well as the discussion by the students of some specific topics are essential to improve the student’s skils in terms of communication, ability in  making conclusions and presenting data to a audience.
