(objectives)
Fishery Ecology
The main purpose of the course is:
TO ACQUIRE KNOWLEDGE AND TOOLS FOR A SUSTAINABLE EXPLOITATION OF FISHING RESOURCES
This will be obtained through the following specific objectives:
1) To understand the rationale behind marine productions and quantification of trophic relationships.
2) To acquire a general knowledge of the Mediterranean nekton, with hints on bio-ecology of the main
species targeted by fishing
3) To have tools such as biostatistical models, equilibrium, growth, age, etc. to demographic study of wild
population with practical exercise in the lab
4) Reconstructing quantitative and structure dynamics of a fished population
5) To have a general knowledge about the main fishing gear, with notes on operation e technical features
and practical exercises on board
6) Assessing exploitation of fisheries resources through statistical models
7) To have awareness on problems and solutions for modern fishing, such as By-catch, protected species,
mitigation systems, and European legislation in the field of fisheries
Experimental Aquaculture:
Students will acquire basic knowledge related to the current state of the aquaculture
sector, methodologies, and farming techniques of the species of greatest global interest.
Specifically, at the end of the course, they will demonstrate:
1 - Knowledge and understanding of the current state and trends characterizing the
aquaculture sector;
2 - Applied knowledge and understanding of the methodologies and farming techniques of
the species of greatest interest to the sector;
3- Developed judgment autonomy through reading, comprehension, and critical analysis of
scientific literature provided during the lessons;
4. Developed communication skills through the presentation of a scientific article;
5. The ability to learn by acquiring familiarity with technical terms and reasoning skills.
