Teaching language



To provide the students with the basic knowledge and training to achieve a clear thinking about the methods of seafood handling and processing, as well as a modern perspective of the food quality and corresponding technical and scientific skills, in order to prepare the students for the professional work they will have to develop. The capacity to criticize, to find and choose the right information and the contact with the realistic professional environment are favoured, by visiting industry facilities. The students should be able to describe, in a critical way, the characteristics and composition of seafood, food degradation, processing and preservation methods, and also quality and freshness evaluation methods.

Learning outcomes and competences

The students must know the basic principles of the use of aquatic foods for humans and for animals, and they must be able to criticize construtively the real actual situation, in order to contribute in the near future for an adequate evolution and development of this technical and scientific area, both in Portugal and abroad.

Eligibility for exams

Minimal class presence: 75% of presential practical classes given; Minimum classification of 9.5/20 on the written exam and 9.5/20 on the poster.

Calculation formula of final grade

60% final exam, 30% poster, 10% reports, participation and assiduity.

Examinations or Special Assignments

Poster on themes taken from actual seafood problems or projects of production of innovative seafood items.

Special assessment (TE, DA, ...)

To be defined in each particular case.

Classification improvement

If the student requires a special examination to improve its classification ("melhoria"=improvement), the classification obtained in the written exam is the only component used to calculate the final classification (the practical component doesn't count).
