Abstract
Iako se dugo godina smatralo da ribe nemaju mogućnost osjeta bola, tijekom posljednjih nekoliko godina sve se češće spominje to pitanje. Novijim istraţivanjima dokazano je da brojne vrste poput riba, mekušaca i rakova posjeduju sustave za percepciju bola. Svaki organizam na drugačiji način doţivljava bol, što znači da je ona subjektivna, a moţe se opisati kao svako neugodno osjetilno ili emocionalno iskustvo koje potencijalno moţe naštetiti organizmu. Zbog malog broja C vlakana kod riba, odgovornih za percepciju bola, smatralo se da ribe ne mogu osjetiti bol. Istraţivanja fizioloških reakcija i promjena u ponašanju organizama dokazala su suprotno. Izbjegavanje štetnih stimulansa, uspješno ublaţavanje promjena analgeticima i posjedovanje struktura za osjet bola tri su glava kriterija za dokazivanje percepcije bola kod riba. Bilo je potrebno više od desetljeća da se dokaţe prisutnost nociceptora kod duţičaste pastrve Oncorhynchus mykiss (Walbaum, 1792). Induciranjem štetnih dogaĎaja dokazane su brojne fiziološke promjene kod riba. Ublaţavanje takvih promjena postiţe se analgeticima, iako mnogi ne ostavljaju ţeljeni učinak. Korištenje analgetika i primjena humanih postupaka nuţni su tijekom manipulacije sa ţivim organizmima jer noviji dokazi sugeriraju na veliku mogućnost percepcije bola. Poţeljno je slične prakse uvesti u ribarstvo i akvakulturu, uz prethodno provedena detaljna istraţivanja.
Abstract (english)
For a long time, it was considered that fishes cannot feel pain, but in recent years that topic is often discussed. It's proven that some species of fish, molluscs and crustaceans have systems for pain perception. Organisms react on different ways, which means that pain is subjective and can be described as unpleasant sensory or emotional experience that can harm organism. It was tought that fishes cannot feel pain since they have small amount of C fibers that are responsible for pain perception. Researches connducted on physiology and behavioural changes prove otherwise. Avoiding noxious stimulans, reducing pain with analgetics and possesion of structures for pain perception are three main criteria for describing pain perception in fishes. More than a decade was needed to prove presence of nociceptors in rainbow trout Oncorhynchus mykiss (Walbaum, 1792). By inducing noxious stimuli, many physiological changes were spotted. Reducing those changes is achieved using analgetics, although many of them don't have desired effects. Using analgetics and humane procedures are necessary during manipulation with live animals because new evidence suggest large possibility of pain perception. Preferably, similar practice should be used in fisheries and aquaculture, after conducting necessary research.
