Credits (ECTS): 
6
Teachning (hours):

Cognitive: The objectives of the course is the study of the systematics, anatomy, morphology, physiology, age and growth, reproduction, ecology and population dynamics of fishes and fisheries management.

Affective: Awareness through the knowledge of fish biology and ecology of the significance of the protection of fish stocks and their management.

Skills: Familiarity with external morphology measurements, analysis of morphometric data, sample construction for age identification and calculation of

fish fecundity, application of statistical and other methods for estimating growth parameters, mortality and population dynamic parameters, and use of

FishBase, the largest electronic encyclopaedia for fishes (www.fishbase.gr), for identifying species and studying their ecology, dynamics and managing

their stocks.

 

Teaching Methods: 

Teaching includes lectures, laboratory work and field exercises, and student self-activity when using FishBase (www.fishbase.org) in order to understand and visualise what they have learned from the course.

Course Contents: 

History, purpose of course. Morphology and systematics. Aspects of physiology. Fish and abiotic environment. Interactions between fishes and other organisms. Age and growth, length-weight relationships, growth parameters. Reproduction and fecundity. Feeding and trophic levels. Mortality and population dynamics. Populations and climate. Migrations. Fisheries and fishing gears. Principles of fisheries management and fisheries models.

 

 

Laboratory Exercises: 

1. Introduction and applications of FishBase (www.fishbase.org), 2. External fish morphology (diversity of external characteristics)–Anatomy, 3. Biometry-Length-weight relationships, 4. Age–growth, 5. FishBase applications (growth parameters and length-weight relationships), 6. Fecundity, 7. Feeding-trophic levels, 8. FishBase applications (feeding ecology and trophic levels), 9.
