Code: 44551
ECTS: 6.0
Lecturers in charge: izv. prof. dr. sc. Ivana Buj
Lecturers: Lucija Novoselec , mag. oecol. - Seminar
Nikola Renić , mag. educ. biol. et chem. - Seminar
Take exam: Studomat
English level:


All teaching activities will be held in Croatian. However, foreign students in mixed groups will have the opportunity to attend additional office hours with the lecturer and teaching assistants in English to help master the course materials. Additionally, the lecturer will refer foreign students to the corresponding literature in English, as well as give them the possibility of taking the associated exams in English.

1. To define mariculture regarding biological and biotechnological principles.
2. To name main components of the manipulation with life cycles of the cultivated species.
3. To name and explain mariculture objectives.
4. To compare yields of the edible organisms and sustainability of fishing and mariculture.
5. To categorize mariculture practices based on different criteria (control level, facilities placement, water exchange dynamics, applied technology, species representation).
6. To analyse positive and negative sides of each cultivation system.
7. To analyse factors influencing quantity of usable marine resources.
8. To identify limiting abiotic factors in mariculture system and propose adequate conditions and solutions for each species.
9. To propose method and cultivation conditions that will be most appropriate for requested species and demands of the mariculturists.
10. To propose adequate food composition and quantity for certain species, life stage and production system.
11. To anticipate critical points in controlled juvenile production and propose adequate conditions and method.
12. To independently conduct researches in order to optimize abiotic factors, feeding and controlled reproduction of the cultivated species, as well as minimizing environmental impacts of mariculture.

1. Definition and aims of mariculture, comparison of mariculture and fisheries, present status and trends in the production of organisms in water.
2. Methods and facilities in cultivation: types of cultivation based on the control level, facilities placement, water exchange dynamics, applied technology and species representation. Attributes and application of extensive, semiextensive, intensive and superintensive cultivation system.
3. Methods and facilities in cultivation: land facilities, comparison and features of open and closed cultivation systems, types of pools.
4. Methods and facilities in cultivation: cultivation in the see, application, construction and zootechnical characters of cage mariculture.
5. Characters of the sea water important for cultivation: abiotic features and their impact on production systems, species and life stages.
6. Food and feeding of the sea organisms: digestions and metabolism, energetic value of the food, consumption, types of food used in mariculture and feeding techniques.
7. Controlled reproduction in mariculture: main criteria for selecting species for controlled reproduction, artificial spawning.
8. Controlled juvenile production: comparison of intensive and extensive production in the spawning facilities, technical organization of the spawning facilities, key parameters in the controlled cultivation.
9. Fish disorders and illnesses: diagnostics, prevention and treatment.
10.Impact of mariculture on environment: sources and effects of waste, impact of nutrients on the benthic communities, impact of the cage production on the benthic communities, methods to mitigate negative impacts of the organic load.
11. Impact of mariculture on environment: deserters from cages, their abundance, effects and prevention.
12. Determining zones for mariculture: spatial prerequisites for mariculture implementation, integrative approach principles.
13. Mariculture based on fisheries.
14. Specifities of invertebrates cultivation.
15. Developmental trends and perspectives.

Students are required to make a seminar based on theoretical grounds or application of mariculture. Written form of the seminar should follow basic principles of scientific papers (literature citing, scientific nomenclature etc.). Besides introduction and elaboration of the theme, seminar should also contain critical thinking, determination of positive and negative sides of a certain method or a case study and proposal of ideas for improvement. Oral presentations comprise presentation design, demonstration and discussion.
