Abstract

Na području današnje Republike Hrvatske komercijalni uzgoj morske ribe započeo je
1980-ih. U listopadu 2009. god., Adris grupa d.d. osniva CROMARIS d.d. za uzgoj bijele ribe
sa sjedištem u Zadru. Danas je CROMARIS prepoznat kao jedna od vodećih tvrtki za uzgoj
bijele ribe u svijetu. Zbog učinkovitog prijenosa između divljih i uzgojenih populacija te širenja
u uvjetima globalnog zatopljenja Sparicotyle chrysophirii postao jedan od najpatogenijih
ektoparazita za uzgoj podlanice (Sparus aurata). Cilj je istraživanja procijeniti gubitke u
kaveznom uzgoju podlanice (Sparus aurata) u uzgajalištu tvrtke Cromaris na otoku Ugljanu u
razdoblju od ožujka do listopada 2021. godine. Usporedbom biomase mortaliteta i abundancije
parazita Sparicotyle chrysophrii (Tablica 6. i Tablica 7.) uočavamo porast mortaliteta unatoč
odsutnosti parazita Sparicotyle chrysophrii, međutim to se može objasniti drugim čimbenicima.
Pojavu Sparicotyle chrysophrii bilježimo od lipnja do listopada, a u istom tom vremenu dolazi
i do pada biomase mortaliteta što znači da Sparicotyle chrysophrii značajno ne utječe na
mortalitet uzgojne ribe u CROMARISU. Tome doprinose preventivne mjere i mjere za
suzbijanje invazije koje se provode na uzgajalištima CROMARISA, a jedna od najznačajnijih
mjera su kupke formalinom.

Abstract (english)

In the territory of today's Republic of Croatia, commercial marine fish farming began in
the 1980s. In October 2009, Adris group d.d. establishes CROMARIS d.d. for cultivating white
fish based in Zadar. Today, CROMARIS is recognized as one of the leading companies for
cultivating white fish in the world. Sparicotyle chrysophirii has become one of the most
pathogenic ectoparasites for the cultivation of the sea bream (Sparus aurata ) due to its efficient
transmission between wild and cultivated populations and its spread under conditions of global
warming. The aim of the research is to estimate the losses in the cage breeding of sea bream in
the Cromaris farm on the island of Ugljan from March to October 2021. By comparing biomass
mortality and the abundance of Sparicotyle chrysophrii parasites, an increase in mortality
despite the absence of Sparicotyle chrysophrii parasites is observed, however, this can be
explained by other factors. The appearance of Sparicotyle chrysophrii is recorded from June to
October, and in the same time there is also a drop in biomass mortality, which means that
Sparicotyle chrysophrii does not significantly affect the mortality of farmed fish in
CROMARIS. Contributing factors to this are the preventive and invasion control measures
implemented at CROMARIS farms, and one of the most significant measures is formalin baths.
