Abstract
Pastrvski grgeč, Micropterus salmoides, (Lacepède, 1802) izrazito je invazivna vrsta s područja Sjeverne Amerike. Na području Male Neretve prvi put je zabilježen 2016. godine. Za potrebe ovog rada prikupljeno je 200 jedinki sa područja od mjesta Opuzen do mjesta Buk – Vlaka te dijela toka prema jezeru Kuti. Za izlov uzoraka korištene su mreže stajačice i štap za varaličarenje, a lov se obavljao uglavnom tijekom ljetnih mjeseci. Analizom 200 jedinki utvrđeno je da se omjer spolova ženki i mužjaka statistički nije značajno razlikovao od očekivanog omjera (1:1) te je iznosio 0,8:1 (χ2 = 2,42; P > 0,05). Ukupna duljina uzoraka kretala se u rasponu 149 - 401 mm. Kod ženki, ukupna duljina tijela u rasponu je od 149 do 332 mm, a kod mužjaka 156 - 401 mm. Prosječna ukupna duljina mužjaka iznosila je 213,06 ± 45,99 mm, a ženki 210,18 ± 47,09 mm. Za morfometrijske odnose nije bilo statistički značajnih razlika između spolova osim u odnosu predleđne udaljenosti i standardne duljine tijela. Također, u analiziranim merističkim osobinama nije bilo razlike u spolovima, a perajna formula podudarala se s perajnom formulom uzorka analiziranog u prvoj zabilješci s Male Neretve. Spolni dimorfizam kod ove vrste nije uočen. Analizom relativnog rasta uočeno je da od 18 omjera 9 je u porastu u odnosu na standardnu duljinu dok ostalih 9 opada.
Abstract (english)
The largemouth bass, Micropterus salmoides (Lacepède, 1802) is a highly invasive species with a native range in North America. The first record in Mala Neretva dates back to 2016. For this study, 200 specimens were collected from the area from Opuzen to Buk – Vlaka, as well as part of the course to lake Kuti. Gillnets and fishing rods were used for sampling. Sampling was carried out mainly in the summer months. Analysis of 200 specimens revealed that the sex ratio was not statistically different from the expected ratio (1:1) and was 0.8:1 (χ2 = 2.42; P > 0.05). The total length of the specimens ranged from 149 - 401 mm. For females, the total length ranged from 149 to 332 mm, while for males it ranged from 156 to 401 mm. The average length of males was 213.06 ± 45.99 mm while in females it was 210.18 ± 47.09 mm. The morphometric ratios show no statistically significant differences between the sexes, except for pre-dorsal fin distance and the standard length. Meristic analysis also shows no difference between the sexes, while the fin equation is exact as specimen described in the first record in Mala Neretva. Sex dimorphism is not observed in this species. Relative growth analysis showed that 9 out of 18 morphometric ratios are incremental in relation to standard length while other 9 ratios are decreasing.
