Abstract
U ovom diplomskom radu napravljena je kvalitativno – kvantitativna analiza sastava ulova obalne potegače za lov gire veličine oka 12 (kontrola) i 40 mm na području otoka Hvara. Uzorkovanje okom 12 mm trajalo je od 5.2.2019. do 8.2.2019. te je napravljeno 10 potega. U ulovu je uočljiva visoka zastupljenost tri koštunjače: Spicara smaris (gira oblica), Boops boops (bukva) i Sardina plichardus (srdela), koje su po brojnosti zastupljene sa 92 % dok njihov ukupni udio u masi iznosi 88 %. Uz ove tri dominantne vrste u ulovu je zabilježena prisutnost 38 ostalih vrsta riba i glavonožaca. Uzorkovanje okom 40 mm trajalo je od 25.2.2019. do 27.2.2019. te je i u ovom slučaju napravljeno 10 potega. U samom uzorku primjećuje se dominantna zastupljenost tri koštunjače, kako u smislu brojnosti tako i u ukupnoj masi ulova: B. boops, S. smaris i M. surmuletus, koje su po brojnosti prisutne s 81,4 % u ulovu, a čine 74,4 % od ukupne mase ulova. TakoĎer u ulovu je prisutno i 36 drugih vrsta riba i glavonožaca.
Abstract (english)
In this master thesis, a qualitative - quantitative analysis of the catch composition of beach seines with mesh size of 12 (control) and 40 mm in the area of the island of Hvar has been made. Sampling with the 12 mm mesh size beach seine lasted from 5.2.2019. to 8.2.2019. and 10 hauls were made. Three species of bony fish dominated the catches: Spicara smaris, Boops boops and Sardina pilchardus, which represented 92% of the total number and 88% of the total weight. In addition to these three dominant species, 38 other fish and cephalopod species were recorded in the catch. Sampling with the 40 mm mesh size beach seine lasted from 25.2.2019. to 27.2.2019. and 10 hauls were made in this case as well. The catches were dominated by three bony fish species, in terms of abundance and the total mass: B. boops, S. smaris and Mullus surmuletus, which accounted for 81.4% of the numbers and 74.4% of the total mass caught. Additionally, the catch contained 36 other species of fish and cephalopods.
