Abstract

U svijetu postoje izuzetno opasni i otrovni morski organizmi, ali oni su u pravilu stanovnici tropskih mora. Nema razloga za paničan strah od stanovnika jadranskog podmorja. Ipak, u njemu žive neke vrste fanerotoksičnih i kriptotoksičnih riba. Primjeri fanerotoksičnih riba su ražovke, paukovke i škrpinke. To su ribe koje pomoću svojih otrovnih aparata i bodlji izravno unose otrov u svoju žrtvu. Dok su kriptotoksične murine, jegulje i ugori. One u svojoj krvi sadrže određene toksine koji mogu biti štetni ukoliko se konzumira neobrađeno riblje meso. Osim ovih stanovnika našeg mora u Jadranu je svoju populaciju uspostavila napuhača, koja sadrži tetrodotoksin, najjači riblji otrov. Tetrodotoksin djeluje iznimno brzo, a smrt nastupa zbog paralize dišnih organa. Otrovi ovih vrsta se sastoje uglavnom od termolabilnih proteinskih otrova, koji se raspadaju dovođenjem topline, ali aktivnost gube i kod snažnog pothlađivanja. Na našim prostorima ljudi su češće žrtve uboda ribe nego trovanja konzumacijom. Ukoliko dođe do trovanja potrebno je potražiti stručnu pomoć zbog problema nastalih djelovanjem otrova, te kako bi se sanirala rana zbog mehaničkog oštećenja tkiva da nebi nastala sekundarna infekcija.

Abstract (english)

There are extremely dangerous and poisonous marine organisms in the world, but they are generally residents of tropical sea. There is no reason to panic about residents of the Adriatic Sea. However, some species of phanerotoxic and cryptotoxic fish live there. Examples of phanerotoxic fish are Rajiformes, Scorpaeniformes and Trachinidae. These are fish that by their poisonous appliances and spikes directly inject poison into victims. While cryptotoxic species are morays, eels and congers. Their blood contains certain toxins that can be harmful if consumed rough fish. In addition to these inhabitants of Adriatic Sea, Sphoeroides pachygaster, which contains tetrodotoxin, the most powerful fish poison, established its population. Tetrodotoxin has exceptionally fast activity, and death occurs due to respiratory paralysis. Poisons of these species consist mainly of thermolabile protein toxins, which decompose bringing the heat and lose activity with a strong hypothermia. In our country people are often the victims of stab poisoning than consumption. In case of poisoning people should seek professional help because of problems arising from the action of poisons, and to repair the wounds due to mechanical tissue damage that could cause a secondary infection.
