Abstract
U ovom radu napravljena je analiza ulova i prilova obalne potegače za lov gire veličine oka 12 i 24 mm, na području otoka Hvara tj. Paklinskih otoka. Tijekom jednomjesečnog istraživanja napravljeno je ukupno 20 potega, po 10 sa svakom mrežom, te analizirano 8856 jedinki riba i glavonožaca ukupne mase 205,9 kg. U ulovu mrežom veličine oka 12 mm zabilježeno je 39 vrsta riba i 2 vrste glavonožaca, među kojima je dominirala gira oblica (Spicara smaris) sa 76,7% od ukupnog ulova, te bukva (Boops boops) s 12,26%. U mreži veličine oka 24 mm našlo se 42 vrste riba i 3 vrste glavonožaca, gdje su također dominirale gira oblica sa 62,73% i bukva sa 14,10% ukupnog ulova. Mrežom veličine oka 24 mm lovljen je manji broj nezrelih primjeraka najzastupljenijih vrsta, npr. zabilježena je samo jedna nezrela jedinka gire oblice od njih 2664, dok je kod mreže veličine oka 12 mm nezrelo bilo 239 jedinki od njih 3535.
Abstract (english)
This thesis analysed the catches and by-catches of beach seine for catching picarel with mesh size 12 i 24 mm in the area of the island of Hvar. During the research period a total of 20 hauls were analysed, 10 with each net, and 8856 specimens of fish and cephalopods were recorded, with total weight of 205.9 kg. In the catches of beach seine with 12 mm mesh size, 39 species of fish and two species of cephalopods were recorded, and dominant species were picarel (Spicara smaris) with 76.7% and bogue (Boops boops) with 12.26% of the total catch. In the catches of beach seine with 24 mm mesh size, 42 species of fish and 3 species of cephalopods were found, and dominant species were also picarel with 62.73% and bogue with 14.10% of the total catch. In the 24 mm mesh very low numbers of immature specimens of the most common species were caught. For example, only one immature picarel specimen out of 2664 was recorded for 24 mm mesh size, compared to 239 immature specimens out of 3535 for 12 mm mesh size.
