Abstract

Patka kržulja (Anas crecca L.) jedna je od najmanjih europskih pataka, svakako najmanja pačja vrsta koja obitava u našim prostorima. U ovom istraživanju tijekom lovne sezone 2019/2020 prikupljeno je 26 uzoraka patke kržulje (13 mužjaka i 13 ženki) s područja triju lovišta u Republici Hrvatskoj. Svakoj jedinki određen je spol i izmjereni su morfometrijski parametri (raspon i duljina krila, duljina i širina glave, duljina, širina i visina kljuna, duljina tijela, duljina i širina tarzusa, ukupna masa, masa trupa, srca, jetre i želuca, te randman). Rezultati istraživanja pokazuju da postoji statistički značajna razlika između spolova u duljini i širini glave, duljini i širini kljuna, duljini tijela, ukupnoj masi i randmanu. Za ostala morfometrijska svojstva nije utvrđena statistički značajna razlika. Randman patke kržulje u lovištima Republike Hrvatske iznosio je za mužjake 69,21%, za ženke 66,52% odnosno prosječno 67,87% te je viši u odnosu na randman patke gluhare. Značajne razlike u morfometrijskim svojstvima u odnosu na populaciju pataka kržulja na sjeveru Europe nema.

Abstract (english)

The Eurasian teal (Anas crecca L.) is one of the smallest European ducks. It is definitely the smallest duck species that lives in our region. Throughout the 2019/2021 hunting season a total of 26 Eurasian teal samples (13 male and 13 female) were collected from the area of three hunting grounds in the Republic of Croatia. The sex of each individual was determined and morphometric parameters were measured (wing span and length, head length and width, width and height of the beak, body length, length and width of tarsus, total weight, carcass, heart, liver and gizzard weight, as well as dressing percentage). Results of the study show that there is a statistically significant difference between the sexes in the length and width of the head, length and width of the beak, body length, total weight and dressing percentage. No statistically significant difference was found for other morphometrical properties. The dressing percentage of Eurasian teal in the hunting grounds of the Republic of Croatia was 69.21% for males, 66.52% for females, and 67.87% on average, which is higher in comparison to the randman of the mallard. There aren't any significant differences when compared to the morphmetrical properties of other Eurasian teal's found in northern Europe.
