Abstract

Kapelska svijetlica (Telestes karsticus Marčić i Mrakovčić, 2011) je stenoendemska vrsta ribe dunavskog slijeva iz porodice Cyprinidae, reda šaranki (Cypriniformes). Pronađena je na samo tri lokaliteta oko Velike i Male Kapele. Cilj ovog rada bio je odrediti starost i značajke rasta kapelske svijetlice kako bi se pridonijelo njenoj zaštiti. Uzorci riba prikupljani su kroz trinaest mjeseci tijekom 2007. i 2008. godine na lokalitetu potok Sušik u polju Lug. Na uzorku od 86 jedinki određeno je šest starosnih skupina, pri čemu u starijim dobnim skupinama dominiraju ženke. Najveći prirast mase i standardne dužine tijela zabilježen je u dobnoj skupini 0+ - 1+, dok je u dobnoj skupini 3+ - 4+ najmanji prirast mase i standardne dužine tijela. Na uzorku od 630 jedinki utvrđeno je da prevladavaju mužjaci, ali ženke dosežu veće dimenzije tijela. Rast populacije kapelske svijetlice okarakteriziran je kao alometrijski pozitivan. Najviša vrijednost Fultonovog koeficijenta kondicije za mužjake i juvenilne jedinke dobivena je u ožujku, a za ženke u travnju. Iz vrijednosti koeficijenta rasta K možemo zaključiti da mužjaci rastu brže od ženki, ali je među ženkama zabilježena veća hipotetska starost pri dužini nula te veća asimptotska dužina.

Abstract (english)

Karst Dace (Telestes karsticus Marčić and Mrakovčić, 2011) is a stenoaendemic fish species of the Danube basin belonging to the family Cyprinidae, order Cypriniformes. It was found only on three sites around Velika and Mala Kapela mountains. The aim of this study was to determine age and growth characteristics of Telestes carsticus in contribution to its protection. Fish samples were collected through thirteen months during 2007. and 2008. on the Sušik stream located in the Lug field. Six age groups were determined in a sample of 86 individuals, with females predominating in the older age groups. Age group 0+ - 1+ has the highest measured body weight and standard body length, while the age group 3+ - 4+ has the lowest body weight and standard body length. In a sample of 630 individuals males predominate, but females reach larger body size. Growth of Telestes karsticus population is positive allometric. The highest values of Fulton condition factor for males and juveniles was obtained in March, and for females in April. From the values of the coefficient of growth K we conclude that males grow faster than females, but among females reported higher hypothetical age at length zero and greater asymptotic length.
