|Theoretical and practical :
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 aquatic 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.
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Knowlegement about the histology and anatomy of fish (mostly teleost), molluscs, crustaceans and aquatic mammals.
1. Central Nervous System (CNS) and Periferic NS
- Hypothalamic factors (GnRH I, II and III), neuropeptide Y, gamma-aminobutyric acid (GABA), dopamine, inhibition of gonadotropin hormone
2. Hypothalamus and Pituitary
- Structure and functioning
- Chemical messengers (target organs)
3. Pineal Gland
- Structure and mode of action / relationship with Central Nervous System
- Photoperiod - Melatonin - Season reproductive
4. Vision, Smell, Sideline, Electroreception
- Physiology of ovaries and testes
- Relationship between the action of the pineal gland, CNS and gonad
- Main stages of development of gametes
- Different types of gonads (fish synchronous, asynchronous, synchronous groups)
- Formation and release of pheromones (examples of various species in which the action of pheromones is essential in reproduction)
- Functions of thyroid hormones in fish and amphibians
- Liver involvement in growth and reproduction
- System Insulin-like growth factor
- Relationship between liver, CNS tissue such as muscle, cartilage and bone
10. Kidney and intestine
- Physiology (sea and freshwater animals)
11. Physiology of molluscs

Eligibility for exams
3/4 attendance considering all types of classes.
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.
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.
