Implementation of biofloc technology in aquaculture

Kao odgovor na sve veći prirodni priraštaj čovječanstva i degradaciju okoliša, nužno je da sektori proizvodnje hrane, poput akvakulture, usvajaju ekološki prihvatljivo gospodarenje i uzgoj organizama. Biofloc tehnologija se temelji na rastu mikroorganizama u vodenom mediju u svrhu poboljšanja kvalitete vode i obrade otpadnih tvari uz minimalnu izmjenu vode i dodatan besplatan izvor proteina za uzgajane vrste. Biofloc sustavi mogu osigurati ekološki sigurnu i financijski održivu proizvodnju u akvakulturi. U ovom radu će se detaljno opisati biofloc tehnologija kao primjer ekološki prihvatljivog gospodarenja u akvakulturi, utjecaj navedene tehnologije na okoliš, njenu ekonomsku isplativost te navesti prednosti i nedostatke obzirom na ostale tehnologije uzgoja u akvakulturi.In response to a high natural increase of human population and environmental degradation, food production sectors, like aquaculture, should adapt to ecologically acceptable management and breeding (cultivation) of various organisms. Biofloc technology is based on the growth of microorganisms in a liquid medium with a purpose of the improvement of water quality and waste management by minimal water exchange (alteration) and additional costless source of proteins for species breeding. Biofloc systems are able to ensure ecologically safe and financially sustainable production in aquaculture. The aim of this thesis is description of the biofloc technology as an example of ecologically acceptable management in aquaculture, its environmental impact and economic cost-effectiveness, also advantages and disadvantages in comparison to other technologies of breeding in aquaculture
