Seasonal variability of fish samples
 Konečná, G. ; Janáč, Michal ; Jurajda, Pavel
We investigated seasonal variability of fish samples on small submontane stream. Study took place on Vlára stream in Bohuslavice town. One identical 100 m long section was sampled monthly from April to November 2005. Sampling was carried out using electrofishing. Totally, 8238 individuals belonging to 18 species were caught. Number of species was constant during the year (mean +/- SE, 10.5 +/- 0.38). Nine most common species were caught each month. On the other hand, in most cases the rest of species was found just once. Gudgeon (Gobio gobio), roach (Rutilus rutilus) and chub (Leuciscus cephalus) were dominant species. Rare species probably came from lentic waters in the river basin and did not make stable populations in the river.
