Objectives
Provide students with knowledge in Animal Health and Pathology, paying special attention to the most frequent pathogens in aquatic animals, in particular in aquacultured fish, given their great importance in terms of food and economics. Present an in-depth look at the various diagnostic methods, advantages and disadvantages and the difficulties in their application to diseases of aquatic animals. Sensitize students to the various aspects in the prevention of diseases in aquatic animals, their impact in aquatic production (economic, social and environmental) and to the importance of an increased investment in sanitary prophylaxis measures.
Learning outcomes and competences
Have knowledge about the different practices and methods of controlling diseases in aquaculture, namely the importance of sanitary prophylaxis. Have a thorough understanding of the various diagnostic methods and their difficulties and limitations. Know the predisposing factors for the occurrence of diseases, as well as the main diseases that affect aquaculture production. Know the various methods of disease prevention in aquatic animals, such as the application of probiotics, immunostimulants and vaccination strategies.

Eligibility for exams
The student cannot exceed the limit number of absences corresponding to 25% of the scheduled classes (in accordance with the “Regulamento Pedagógico e de Avaliação do Aproveitamento dos Estudantes” of ICBAS, Art. 19, Point 2).
Calculation formula of final grade
A - Final exam (75%)
B - Preparation and presentation of scientific paper (25%)
Final grade - A x 0,75 + B x 0,25
Lack of presentation of scientific paper implies a classification of zero (0) for this component, in which final grade - A x 0,75 + 0.
Examinations or Special Assignments
Preparation and presentation of scientific paper.
Special assessment (TE, DA, ...)
Examination equal to other students, benefiting from the special dates in accordance with the rules in force at ICBAS. Student-workers, with dispensation for pratical classes, the final grade will the the exam grade (A - 100%)Classification improvement
Examination for grade improvement in accordance with the rules in force at ICBAS, keeping the same grade for the other evaluation components.
