Abstract
Za potrebe ovog rada uzorkovane su 82 jedinke gire, Spicara smaris (Linnaeus, 1758) uhvaćene obalnom potegačom migavicom na području Hvara. Dužinski raspon uzorkovanih gira iznosio je od 7,5 cm do 16,4 cm. Testom propadanja svaka gira se pokušala provući kroz niz romboidnih oka točno definirane veličine i kuta između susjednih stranica. Na temelju rezultata provlačenja kreiran je model za predikciju selektivnosti oka upotrebljenih u testu propadanja. Prediktivni model je zatim iskorišten za utvrđivanje distribucije mrežnih oka u vreći pridnene povlačne mreže koće izrađene od romboidnog oka veličine 42,4 mm za koju nam je poznata selektivnost. Za navedenu vreću ustanovljeno je da kutovi od 25° do 45° najviše doprinose objašnjavanju eksperimentalne krivulje.
Abstract (english)
For this study, a total of 82 specimens of picarel Spicara smaris (Linnaeus, 1758), were collected in the Adriatic Sea, using the small coastal boat seine “migavica”. The specimens were ranging from 7,5 to 16,4 cm in total length. Fall-through experiments were carried out to decide if each fish can physically pass through series of diamond meshes with defined sizes and opening angles. The results of the fall-through experiment were used to create a predictive size selection model for the meshes used in the fall-through experiment. The predictive model was used to determine the distribution of the mesh opening angles in 42,4 mm diamond bottom trawl codend for which size selection is known. The angles mostly varied from 25 to 45 degrees.
