Abstract
Plemenita periska (Pinna nobilis Linneanus, 1758) je jedan od najvećih školjkaša i endem Sredozemnog mora. Zbog masovnog pomorom koji se pojavio 2016. u zapadnom Sredozemlju brojnost joj opada, a u Jadranskom moru je pomor zabilježen tek 2019. godine. Cilj ovog rada je odrediti starosnu i veličinsku strukturu populacije plemenite periske u Malom jezeru Nacionalnog parka Mljet prije masovnog pomora. Terensko istraživanje za vrijeme kojeg su sakupljeni podaci o brojnosti jedinki i morfometrijskim mjerama je provedeno u ljeto 2018. Zabilježeno je 3800 jedinki, od kojih je 3567 bilo živo. Prosječna gustoća populacije bila je 30,96 ± 14,42 jedinki/100 m2 čime je ovo jedna od najgušćih zabilježenih populacija u Jadranskom moru. Najboljom jednadžbom za izračun ukupne dužine školjke na ovom lokalitetu se pokazala jednadžba: 𝐻𝑡 = 1,79𝑤 + 0,5 + 𝑈𝐿 gdje je Ht ukupna dužina školjke, w je minimalna širina, a UL je dužina nezakopanog dijela školjke. Prosječna izračunata ukupna dužina jedinki bila je 62,20 ± 6,39 cm, a najveća jedinka imala je 87,30 cm. Iz ukupne dužine jedinki izračunata je starost populacije te je 50 % jedinki bilo u starosnom rasponu od 10 do 15 godina. Također, zamijećena je pozitivna korelacija između veličine plemenitih periski i dubine na kojoj se nalaze.
Abstract (english)
The fan mussel (Pinna nobilis Linneanus, 1758) is one of the largest shellfish and endemic to the Mediterranean Sea. Due to the mass mortality event that started in 2016., while in the Adriatic Sea was documented in 2019, its numbers were sharply reduced. This paper aims to determine the age and size structure of the fan mussel population in Malo jezero, Mljet National Park before the mass mortality event. Field research during which data on the number of individuals and morphometric measures were collected was conducted in the summer of 2018. 3800 specimens of fan mussel were recorded, of which 3567 were alive. The average population density was 30,96 ± 14,42 individuals/100 m2 , making this one of the densest recorded populations in the Adriatic Sea. The best formula for calculating the total length of the shell, in this case, was: 𝐻𝑡 = 1,79𝑤 + 0,5 + 𝑈𝐿 where Ht is the maximum shell length, w is the minimum width and UL is the unburied length. The average calculated total length of individuals was 62,20 ± 6,39 cm while the largest individual was 87,30 cm. The age of the population was calculated from the total length of the individuals and 50 % of individuals were in the age range of 10 to 15 years. In addition, a positive correlation was observed between the size of the fan mussel and the depth at which they were found.
