Learning objectives
The main goal is to provide students the essential knowledge about world market of fish products, biology and production techniques of the main fish species. In particular, the chemical-physical characteristics of the water, the biology of aquatic species, the reproduction, the rearing systems, the nutritional requirements, the feeding techniques and the effects of different rearing parameters on the organoleptic and nutritional characteristics of fish, molluscs and shellfish will be discussed.
Expected learning outcomes
Acquisition, also through laboratory activities and technical visits at fish farms and processing plants, of specific skills and critical sense useful for operating in the aquaculture and fish product sectors. The student will also acquire the knowledge necessary to identify the main farmed and caught aquatic species and to evaluate the quality and freshness of fish products.
Course syllabus and organization

Single session

Lesson period
First semester
Most of the lessons will be held on the Microsoft Teams or Skype platforms, while some lessons, situation permitting, will be in attendance. The methods and criteria for participating in face-to-face lessons, which require a reservation with a special app, will be published in time on the Ariel pages of the course.

The exam will take place orally using the Microsoft Teams or Skype platforms or, where the regulations allow, in person, always in oral form.
Course syllabus
The program is structured as follows:
- general aspects of fishing and aquaculture and production and consumption of fish and fish products in Italy and in the world; processing, packaging and labelling of seafood products (½ ECTS)
- basic aspects of systematic and biology of fish species; identification of the most important aquatic species for human consumption; nutrition and feeding (1 ECTS)
- description of different production systems used in aquaculture; characteristics of the systems and equipment for rearing; chemical and physical characteristics of water and water management (1 ECTS)
- production of sea bass and sea bream; production of trout and salmon; production of sturgeon and ell; production of alternative fish species; rearing techniques of molluscs and crustaceans (2 ECTS)
- aquaculture for conservation of wild fish populations; aquaculture in the developing country and production techniques of tilapia (½ ECTS)
- nutritive values of fish and aquaculture products and factors affecting quality; evaluation of quality parameters of fish product; environmental impact of intensive rearing (1 ECTS)
Prerequisites for admission
Basic knowledge of biology, animal anatomy and physiology and animal husbandry and feeding.
Teaching methods
Frontal lesson; seminars, case studies and student involvement with the aim to study in depth and verify the topics. Students are recommended to attend lessons.
Teaching Resources

Assessment methods and Criteria
Oral exam and the evaluation is expressed by a vote out of thirty. Students will have to demonstrate, also through Power Point presentation of a topic discussed during the lessons, theoretical knowledge and capability of critically analysing the different production systems used in aquaculture and nutritive values of fish and aquaculture products.
