Abstract

Plemenita periska stekla je status ugrožene vrste antropogenim učincima, a zakonom
je zaštićena od 1992. godine. Dodatnoj ugrozi pridonijeli su patogeni Haplosporidium pinnae
i Mycobacterium sp., zasad poznati uzročnici masovnih pomora koji su zahvatili područje
čitavog Sredozemnog mora. Masovni pomori zabilježeni su od 2019. i u Jadranskom moru.
Određene mjere kojima se nastoji prevenirati izumiranje vrste već su na snazi.
Cilj ovog rada bio je prikazati kratki pregled širenja masovnih pomora Sredozemnim
morem i opisati njihove zasad otkrivene uzročnike. Također, navedene su i radnje koje se
poduzimaju u svrhu očuvanja vrste ovog školjkaša.
Učinak globalnog zatopljenja, odnosno zagrijavanje mora, djeluje posve suprotno na
organizme domaćina i njihove patogene. Dok kod domaćina vodi k slabijem odgovoru
imunog sustava, više temperature optimalne su za patogena te mu osnažuju virulenciju.
Plemenite periske smatraju se indikatorom zdravlja mora, te bi njihovo moguće izumiranje
moralo djelovati na ljude kao upozorenje za organizme drugih vrsta.

Abstract (english)

The noble pen shell reached the status of an endangered species due to human impacts
and it is legally protected since 1992. Parasites Haplosporidium pinnae and Mycobacterium
sp., so far known agents of mass mortality outbreaks that took hold on fan musell's
populations throughout the Mediterranean. Massive mortality events have also been recorded
in the Adriatic Sea since 2019. Certain measures for preventing the extinction of Pinna nobilis
are already taking place.
The main aim of this paper was to present a short overview on the expansion of mass
mortality events in the Mediterranean and describe its causative agents. Activities for the
preservation of the species are also presented.
The effect of global warming, i.e. the raising of sea temperatures has an opposite
impact on the host and its parasites. In the case of the host, it leads to a weakened immune
system, while the parasite's virulence strengthens. The noble pen shell is considered as an
indicator of the ocean's health, and its possible extinction must be a warning sign for other
species.
