Description
| - Po téměř sto letech byl zjištěn opětovný výskyt drska menšího v oblasti soutoku řek Morava a Dyje.Populace tam sestávala z jedinců 0+ až 5+, při čemž převládala věková skupina 0+. To svědčí o tom, že se tam tento druhu úspěšně rozmnožoval v roce 2003. Byla provedena analýza karyotypu (n=5) a meristických znaků (n=10). Byl zjištěn následující růst délky těla (n=16): SL1 – 81 mm, SL2 – 114 mm, SL3 – 130 mm, SL4 – 146 mm, SL5 – 166 mm. Největší jedinec, samice ve věku 5+ měl TL 200 mm, a SL 180 mm. Jedinci ve věku 0+ preferovali proudivé úseky se štěrkovitým dnem, kde rychlost proudu byla 0,2 až 0,6 m.s -1. Obnovení výskytu tohoto druhu bylo umožněno výrazným zlepšením kvality vody po roce 1990 a bezbariérovým spojením úseků Moravy a Dyje s Dunajem přes slovensko-rakouskou část řeky Moravy. (cs)
- Almost after a century, the occurrence of Zingel streber (Siebold, 1863) was recorded again in the area of confluence of the rivers Morava and Dyje. The population consisted of fish 0+ to 5+, with 0+ group predominating in the sample, indicating that the species had successfully reproduced in 2003. Analysis was made of their karyotype (n=5) and meristic characters (n=10). The following was the result of a study of growth of standard lengths (n=16): SL1 ů 81 mm, SL2 ů 114 mm, SL3 ů 130 mm, SL4 ů 146 mm, SL5 ů 166 mm. The biggest individual was a female 5+ of age, TL 200 mm, SL 180 mm. The habitat types preferred by individuals 0+ were the rapidly flowing sections with gravel bottom, in which the stream velocity was 0.2ů0.6 m.s-1. Re-occurrence of this species was facilitated by the marked improvement of water quality after 1990 as well as by the barrier-free connection of sections of the rivers Morava and Dyje with the Danube via the Slovakian-Austrian part of the River Morava.
