Objectives
Students should understand the characteristics, operations, challenges and future perspectives of the general activity of world fisheries (industrial and artisanal), with emphasis on European and Portuguese fisheries (mainland and islands). The objective is also that they know and understand the justification, planning, main calculations, evaluation, practical application and consequences of the main measures for the sustainable management of stocks of aquatic species.
Learning outcomes and competences
Knowledge, in some detail, of the history of fishing, the fishing gears and methods oand industrial and artisanal fishing vessels, including the characteristics of utensils, equipment and materials (mainly cables and nets) used in world and Portuguese fisheries (Mainland, Azores and Madeira) and recognize the main measures for the assessment and management of stocks and fisheries management in general. This knowledge allows a critical view, based on proven scientific data, of one of the most traditional, largest and most relevant human activities carried out in water.
Working method
Presencial
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Basic notions of Biology/Ictiology of main species from fisheries.
Program
Fisheries Technology
I) Introduction: definitions and general concepts
II) History of fishing: from prehistory to today
III) World and European fisheries: main statistical data
IV) Fish catching gears and methods: types, description and classification
V) Fishing vessels: types, description and classification
VI) Materials used in fishing: types, characteristics, influence on the environment (includes practical session on net measuring and how to make knots)
VII) Equipment used in fishing: safety, detection, fishing, environmental protection
VIII) Fishing issues: overfishing, bycatch, by-mortality, ghost fishing, environment, sustainability, animal welfare
IX) Fishing, welfare and fish quality
X) Fishing in mainland Portugal, Azores and Madeira: main characteristics and general organization
Fisheries Management
I) Management of catches and effort management.
II) Concepts of selectivity, fishing effort and fishing mortality.
III) Factors that influence the selectivity of fishing gears.
IV) Management of by-catches and minimization of discards. By-catch reduction devices (BRD's).
V) Applications to the preservation of fisheries resources.
VI) New technologies for monitoring fishing activities and their importance in fisheries management.
Practical classes and visits

Eligibility for exams
According to the U.Porto regulations (presence in 3/4 of classes).
Calculation formula of final grade
Written examination about two components: Fisheries Technology (10 points maximum) + Fisheries Assessment and Management (10 points maximum) = 70% final classification.
Presentation and discussion of a scientific work = 30% final classification.
Examinations or Special Assignments
Presentation and discussion of a scientific work = 30% final classification.
Special assessment (TE, DA, ...)
Accordin to the law in force at the moment.
Classification improvement
In exams to improve the obtaibned classification, only the classification of the exam is taken into account. The classification obtained in the presentation and discussion is not considered.
