Abstract
Udica je osnovni element udičarskih alata. Odabir adekvatne udice prvenstveno ovisi o vrsti i veličini ciljane lovine, a ribolovcima je trenutno na tržištu dostupan jako velik broj udica različitih veličina i oblika. U ovom radu pozabavit ćemo se usporedbom dva karakteristična oblika udica, tradicionalnim „J“ i okruglim „O“ oblikom udice. Jedna od osnovnih prednosti okrugle udice u odnosu na tradicionalni „J“ oblik je što okrugla udica ima manju vjerojatnost dubinskog kačenja lovine, što je posebno važno kod „ulovi i pusti“ ribolova. Generalno gledajući, okrugla udica nije toliko efikasna u ulovu u odnosu na tradicionalni oblik udice, ali to prvenstveno ovisi o vrsti koja se izlovljava. U gospodarskom ribolovu pelagičnim parangalima upotreba okruglih udica pokazala se značajnim faktorom, koji doprinosi smanjenju ulova neciljanih vrsta poput morskih kornjača, zbog čega je u nekim ribarstvima upotreba okruglih udica postala zakonska obaveza.
Abstract (english)
Fish hook represents one of the most important tools in human history. Today, fishermen have huge number of fish hooks available to them when preparing for fishing. The size and shape of hooks mostly depend on the size and species of targeted fish. In this paper, we are concentrating on the comparison of traditional „J“ and circle „O“ shape hooks. The use of circle hooks often results in shallow hooking compared to traditional “J” type hooks, what has been recognized as a major advantage in “catch and release” fisheries. In general, results showed that circle hooks have significantly lower catch efficiency compared to “J” type hooks. In pelagic trawl fishery, the use of circle hooks proved to be a significant factor affecting mortality of bycatch species such as sea turtles, which is the reason why in some countries circle hooks are mandatory.
