B6077 - Buildings and Plants

Learning outcomes

At the end of the course, the student acquires general knowledge relating to the systems and construction techniques of animal husbandry works and is able to carry out their management and general planning.

Teaching methods

Each topic covered with frontal teaching is accompanied by an explanatory numerical example or practical example.

The hours of frontal teaching are associated with hours of personal assistance in the analysis of intensive aquaculture systems equipped with wastewater treatment phases.

During the course, with the assistance of the teacher, students write a personal or group paper for the design or verification of an intensive farming system on land or at sea.

Assessment methods

Learning is verified through a final oral exam which verifies the acquisition of the expected knowledge and skills. This exam consists of three questions, each relating to one of the three main parts of the teaching program: Hydraulics, Plants and Buildings for breeding, Plants and Buildings for treatment.

For those attending, the oral exam will consist of the oral presentation of the personal or group work created during the lessons.

Passing the exam will be guaranteed to students who demonstrate knowledge and mastery of the fundamental concepts illustrated in the teaching and a higher score will be attributed to those who demonstrate that they are capable of using all the application contents provided in lessons and of illustrating them with the ability to language.

Teaching tools

° Preventive delivery of PDF files uploaded to virtual and used in frontal teaching.

° Virtual delivery of an updated compendium of the current technical legislation regarding the regulation of discharges and the supply, treatment and reuse of waste water.
