Abstract

Recirkulacijski akvakulturni sustavi (RAS) služe za uzgoj riba ili drugih akvatičnih organizama ponovnim korištenjem vode u proizvodnji krajnjeg produkta. Navedenom tehnologijom se upravlja kvalitetom uzgojne vode u svrhu održavanja dobrobiti riba. Uzgoj afričkog soma (Clarias gariepinus) u RAS-u na ribnjacima „Kupa“ Draganid predstavlja suvremenu metodu proizvodnje ribe tijekom cijele godine. U radu su obrađeni segmenti tehnologije uzgoja afričkog soma, od odabira matičnog stoka, preko uzgoja... More ličinki i izlova konzuma, kao i izvedba RAS-a na ribnjacima „Kupa“. Uz vede početne investicije te nužno adekvatno znanje pri uspostavi i upravljanju RAS-om, na ribnjacima „Kupa“, problemi se posljedično javljaju najviše u vidu nepovoljnih fizikalno-kemijskih pokazatelja vode što uzrokuje zatim i relativni pad proizvodnje afričkog soma u RAS-u. Mogudnost unaprjeđenja RAS-a na navedenoj lokaciji prvenstveno leži u obnovi temeljne infrastrukture, čime bi se potencijalno otklonili nedostaci koji narušavaju optimalnu uzgojnu sredinu. Dodatno, uvođenjem automatskih hranilica vjerojatno bi se osigurao i bolji prirast mlađi afričkog soma. Less

Abstract (english)

Recirculating aquaculture systems (RAS) are used for rearing of fish or other aquatic organisms by reusing water. This technology manages the quality of water for the purpose of maintaining fish welfare. The cultivation of African catfish (Clarias gariepinus) in RAS on the Kupa ponds Draganid is a modern method of fish production throughout the whole year. The thesis deals with segments of African catfish farming technology, from broodstock selection to rearing larvae and adult fish, as well... More as the implementation of RAS on Kupa ponds. With higher initial investment and the necessary adequate knowledge in establishing and managing RAS, on „Kupa“ ponds, consequently, problems occur mostly in the form of unfavorable physicochemical indicators of water, which then causes a relative decline in the production of African catfish in RAS. The possibility of upgrading the RAS at that location primarily lies in the renewal of the basic infrastructure, potentially eliminating deficiencies that impair the optimal breeding environment. Also, the introduction of automatic feeders would probably ensure better growth performance of the African catfish juveniles. Less
