Abstract

Provedeno je istraživanje procjene gustoće i strukture populacija plemenite periske
(Pinna nobilis) na 8 lokacija duž Paškog zaljeva. Koristila se metoda transektnog vizualnog
cenzusa ronjenjem na dah uz uporabu autonomnog ronilačkog aparata (SCUBA) i plovila
opremljenog side scan tehnologijom. Kvadratni transekti određeni su površinom od 900 m².
Tijekom istraživanja, uz dokumentaciju osnovnih mjera periski (nadzemna visina, maksimalna
širina) i mortaliteta, bilježena je i vrsta supstrata... More te dubina mora. Gustoća periska varirala je
između 0,67 – 2,33 živih jedinki / 100 m², a zabilježen mortalitet iznosio je od 56 do 100 %
ovisno o istraživanoj lokaciji. Primijećena je određena povezanost između strukture staništa,
nadzemne visine, temperature i dubine mora u odnosu na mortalitet jedinki. Less

Abstract (english)

Evaluation of density and population structure of Pinna nobilis on 8 locations in Pag
Bay was conducted. Methodology of transect visual census by scuba diving breathing
apparatus (SCUBA) and vessel equipped with side scan technology was used. Quadrants
transects are determined by area of 900 square meters. During the research, besides
recording of basic measurements (height, maximum width) and mortality rate of Pinna
nobilis, type of substrate and sea depth was recorded. Density of Pinna... More nobilis was between
0.68 and 2.33 of living individuals per 100 square meters, and recorded mortality was
between 57 and 100 % depending on location. Connection between structure of habitat,
height, sea depth and temperature comparing to mortality of individuals are observed. Less
