Objectives

Following the knowledge of anatomy, histology and comparative animal physiology previously acquired, it is projected now address, a perspective more particular aspects related to the physiology of aquatic animals with emphasis on fish, but also covering topics selected mollusks, crustaceans and mammals.

With the approach aims to become an emphasis of integrating aspects of endocrinology, particularly with interest applied to the areas of reproduction and growth. Elected as central pedagogical concern the ability of the student to be an active element in the search for knowledge and exploration of unreleased songs from the scope of the unit, using the knowledge that has systematically from their experience as a student of the aquatic sciences.

Learning outcomes and competences

Provide students with the ability to better understand the physiology of organs and systems of aquatic animals, including a perspective of neuro-endocrine integration and adaptive needs against environmental changes.

Understand the importance of key environmental factors on the physiology of aquatic animals, through case studies and appreciating diversity. Understanding how physiological knowledge can be applied to practical problems in production and biomonitoring.

Increase the ability of students searching, selecting, critically analyze and present information of a physiological, schematically and integrating it with previously learned concepts.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	60,00
Participação presencial	40,00
Total:	100,00

Amount of time allocated to each course unit

Designation	Time (hours)
Estudo autónomo	86,00
Frequência das aulas	49,00
Total:	135,00

Calculation formula of final grade

Final rating = Note theoretical final exam (60%) + Note continuous assessment (40%)

The scores for each component are initially assigned on a scale of 0 to 20. It requires 9.5 minimum grade for approval as each of the components in question.

Continuous assessment rewards attendance, level of commitment, and even the quality of performance of each student during the lessons.

Classification improvement

After an initial approval to the course the student may apply for grade improvement final exam. No substitution of continuous evaluation score by any act of nature alone. A possible improvement in continuous assessment involves attending classes again, performing all activities inherent.
