| Popis: | Razvojem uzgoja ribe u moru povećalo se zanimanje za praćenje njihova zdravstvenoga stanja. Razlog su tome bolesti, odnosno uginuća, koja se pojavljuju u takvim ribogojilištima, te uzrokuju velike ekonomske gubitke. Smještajem velike količine ribe na malu površinu promijenjeni su prirodni uvjeti, pa je osjetljivost i podložnost ribe uzročnicima (virusima, bakterijama, parazitima) bolesti veća. Osim toga, velika gustoća riba u uzgoju pospješuje širenje bolesti, ali isto tako i njihovo bolje zamjećivanje. Kod divljih populacija oboljele jedinke brzo postanu plijen grabežljivaca, pa je i uočavanje patološkoga stanja takvih riba otežano. Danas postoji niz napisa o virusnim, bakterijskim i parazitarnim bolestima, ali je ovdje pažnja posvećena isključivo bakterijskim bolestima koje se javljaju u kontroliranom uzgoju u moru (vibrioza, furunkuloza, pastereloza, nokardioza, mikobakterioza, edvardsieloza, jersinioza, bolesti uzrokovane bakterijama roda Flexibacter, Pseudomonas, Aeromonas, Streptococcus i bakterijski nefritis). Pritom, spoznaje o njima veoma variraju, ovisno o tome uzgaja li se neka morska vrsta ribe već duže razdoblje ili se tek uvodi u kontrolirani uzgoj. With development of the fish culturing in the sea, the interest in their health also increased. The reason for this are diseases or rather mortality that occur in such controlled cultures and cause great economic losses. By growing large quantities of fish in rather small species, natural conditions are changed, so fish is more sensitive and prone to infection agents (viruses, bacteria, parasites). Besides, a large fish density in the cultural process accelerates spreading if the diseases, but also enables a better perception of them. In wild populations sick specimen very quickly become predator’s prey, witch makes it difficult to note any pathological changes in such fish. There are lots of articles on viral, bacterial and parasitic diseases nowdays, but this work deals exclusively with bacterial deseases that occur in the controlled sea cultures (vibriosis, furunculosis, pastherelosis, nocardiosis, mycobaceriosis, edwardsielosis, yersiniosis, deseases caused by bacteria of genera Flexibacter, Pseudomonas, Aeromonas, Streptococus and bacteria nephryithis). Yet, the knowledge of these deseases vary, depending on wether a fish species is being cultured for a longer period of time or is only being introduced in the controlled culture. |
