Undergraduate Studies

 Each academic year, about 40 students of the Faculty of Animal Science and Aquaculture are educated (lectures and practice) in topics of Hydrobiology, Aquaculture and Production of Aquatic Animals, within the frame of the undergraduate program of the Faculty of Animal Science and Aquaculture.

Approximately 4-6 students choose to be further educated in this scientific field through their 4-months practice period, as well as their thesis to obtain their final degree. These students obtain in-depth education in specific issues related to aquaculture: operation and maintenance of recirculating water systems, maintenance of fish populations, handling of live fish (e.g. netting, grading, transport, anaesthetization, weighing, body measurements), fish dissection, sampling of biological material (blood, liver, fillet, brain, digestive tract etc.), specific laboratory analytical techniques on biological material.

Students of all other Departments of the Agricultural University of Athens receive a few lectures of general hydrobiology and aquaculture issues within the frame of the course “Animal Breeding and Husbandry” (Code: 125) in their 5thsemester of studies.

Since 1991, the Department of Applied Hydrobiology participates in EU/ERASMUS, EU/TEMPUS and LEONARDO educational programs. Up to day students from UK, Bulgaria, Poland, Italy and Norway were educated, through special lectures and laboratory experience, in aquaculture related issues.

 

Taught courses

 Hydrobiology (7thsemester, Code: 93)

Description of the course:Physical and chemical propertiesof water. Natural water bodies(hydrogeographical features, formation of surface water bodies). Geological and morphological characteristics of natural water bodies(coastal, continental shelf, continental slope, seabed, rivers, sediments). Physical characteristics of water areas (movements of sea water-waves, tidal phenomena, ocean currents, eddies, water movementsin lakes and lagoons. Temperature of natural water bodies. Transparency, light, color and turbidity in sea, lake and river waters. Hydrostatic pressure and speed of sound in the aquatic environment). Chemical characteristics of natural water (composition and pH of sea, lake and river water - the main mineral elements and compounds, gases, nutrients, etc.). Theaquatic life (plankton, benthos, nekton, neuston). Food chain.Primaryproduction. Physiology of aquatic organisms (osmotic and ionic regulation in marine organisms, freshwater and brackish-water vertebratesand invertebrates). Respiration of aquatic organisms (respiratory mechanisms-gills, respiratory pigments). Floatingofaquatic organisms.Soundproduction by aquatic organisms. Laboratory practice (sampling methods of plankton and water in the field, phyto- and zooplankton composition – determination of water quality).

 

Aquaculture (8thsemester, Code: 41)

Description of the course:Introduction-importance of aquaculture (definitions, aims, present state worldwide, in Europe-Mediterranean, in Greece). Basic principles of aquaculture (Comparison among aquaculture products. Biological basis of aquaculture. Water quality for aquaculture. Site selection for aquaculture farms. Interaction among physical, biological and financial conditions. Criteria for selecting aquatic organisms suitable for aquaculture). Aquaculture production systems (Human involvement, water manipulation and types of facilities. Production of fish, crustaceans, molluscs, phytoplankton, zooplankton, higher aquatic plants). Main production stages in aquaculture (broodstock maintenance and maturation, artificial spawning, fertilization, incubation of fertilized eggs, hatching, survival and growth of hatched larvae, growth up to commercial size). Basic principles of aquaculture farm management (Selection of farmed/cultured organism. Size of aquaculture farm. Determination of pursued yield. Growth rate and nutrition of fish, crustaceans, molluscs, phytoplankton, zooplankton, higher aquatic plants. Determination of primary production of controlled or natural sea or fresh water bodies. Differentiation of aquaculture farms according to products). Fish anatomy.

 

Production of Aquatic Organisms (9thsemester, Code: 36)

Description of the course:Definition, aim, importance, types and categories of aquaculture constructions (ponds, tanks). Types, shapes and sizes of fish ponds (construction, preparation, operation, management). Types, shapes and sizes of fish tanks. Specific construction for fish confinement and rearing (sea cages, bottom cages, pens and enclosures). Ponds and tanks for farming of crustaceans. Constructions for molluscs farming (mussels, oysters). Constructions for production of phytoplankton, zooplankton, aquatic plants. Pumps (use, categories, combinations, tubing). Artificial aeration (aerators types, operation). Facilities – constructions for artificial reproduction and breeding of first life stages of fish, crustaceans and molluscs. Mechanical equipment of aquaculture farms. Fishing gear. Facilities maintenance and repair.Constructions – equipment for transportation of live aquatic organisms. Laboratory equipment and apparata. Biotechnology in aquaculture. Fish endocrinology (focus on endocrinology and fish farming). Fish physiology. Diseases of farmed aquatic animals. Evaluation of aquaculture farms. Farming of main commercial fish, crustacean and mollusc species. Crustacean and mollusc anatomy.
