“…Brown trout, rainbow trout and grayling decreased in section C although these species were regularly stocked upstream by a local fishery, and a considerable number of brown trout and rainbow trout was recorded during downstream migration after stocking (Hladík and Kubečka, 2003). Interference of the salmonids and the reservoir fish and/or their offspring colonising the river from spawning grounds can be assumed, but other possible unidentified factors cannot be omitted completely.…”

“…A considerable portion of the chub population within the river used the reservoir as a winter refuge (Hladík and Kubečka, 2003). Dace were able to utilize the still-water conditions in the reservoir and accounted for 4.4% (on average) of the reservoir fish assemblage in 2000-2002 (Říha et al, 2008).…”

“…All samplings were performed outside of 'spawning migration peaks' , i.e. outside upstream and following downstream migration of fish from the reservoir (Hladík and Kubečka, 2003), to sample resident fish only. Only fish 1+ and older were considered.…”

ABSTRACT:The construction of the Římov Reservoir on the Malše River in 1978 significantly influenced the fish assemblage within the river, above the reservoir. Fish species that had successfully colonised the reservoir after impoundment expanded to the inflowing river. The changes in the riverine fish assemblage up to the first impassable weir (4 km upstream) reflected the development of the reservoir assemblage after an impoundment boom of pike (Esox lucius), then the perch (Perca fluviatilis) dominated phase and later the final cyprinid-dominated phase. The changes in the fish fauna over the period 1978-2002 were significant (χ 2 , P < 0.001). During the cyprinid-dominated phase, roach (Rutilus rutilus) became the most abundant species both in the reservoir and in the river, outnumbering the pristine river species. We conclude that the cyprinid-dominated assemblage in the reservoir can be more aggressive in interfering with the river assemblage than the percid-dominated one.

“…It also seems that other species migrate upstream to middle reservoirs through open gates (equal water level) and to tributaries for spawning (Šebela, 2000). According to the number of fish species and their abundance, the presence of tributaries could play a similarly crucial role for fish reproduction in these lowland reservoirs as it does in deep valley reservoirs (Hladík and Kubečka, 2003). Perhaps, the succession stage of lake and habitat and fish community stability in particular reservoirs could influence the natural reproduction of fish (Baruš, pers.…”

A synchronous study of 0+ juvenile fish in three lowland reservoirs (Mušov, Věstonice, Nové Mlýny) of the Nové Mlýny dam (Czech Republic) was conducted in July 1997. Fish were sampled by fry beach seine and backpack electro fishing gear at 32 sites in three types of inshore habitats: concrete stepped embankment, stony riprap and sandy-gravel beach. In total, we registered 0+ juvenile fish of 17 species and one hybrid. The most common species was bleak Alburnus alburnus (62.7%), followed by roach Rutilus rutilus (12.8%), ide Leuciscus idus (6.2%) and asp Aspius aspius (5.5%). More than 53% of 0+ fish samples were caught in beach sites, 43% in rip-rap sites and only 3.4% in concrete embankment. The li�oral assemblages of 0+ fish differed between the three adjacent reservoirs and also between the shoreline types.

“…The basic assumption being that its prey items are flushed out into the water column by rapidly advancing water (e.g., drowning mice, ants) in the inundated floodplains. Similarly, fish prey (especially some cyprinids) might respond more to changes in water flow rates (e.g., Hladík and Kubečka 2003) at decreasing water levels which would make them more vulnerable to predation. This increased piscivory at reduced water levels results in a lengthening of the food chain, which in turn results to a less efficient energy transfer.…”

Mosepele K., Mosepele B., Wolski P., Kolding J. 2012. Dynamics of the feeding ecology of selected fish species from the Okavango River delta, Botswana. Acta Ichthyol. Piscat. 42 (4): 271-289.Background. This study contributes to the understanding of the potential impact of changes in flooding patterns and (potential) fish production as a consequence of upstream developments in floodplain systems. Therefore, stomachs of eight fish species from the Okavango Delta were analysed to evaluate the feeding ecology of floodplain fish (and the effect of seasonal flooding), using the delta as a case study. Materials and methods. In total, 2101 fish stomachs of eight species, representing six families, were collected (in all seasons) from the delta using experimental fishing nets, from 2004 to 2009. Frequency of occurrence, Levin's diet breadth index, Pianka's overlap index, trophic levels, and Bray-Curtis similarities were used to evaluate feeding preferences. Detrended correspondence analysis was used to study temporal variations in diet. Multiple linear regressions were used to determine the influence of flooding on diet. ANOVA and MANOVA were used to determine the level of significance among variables, while LSD post hoc analysis revealed the source of significance.Results. Cluster analysis and Pianka's index highlighted inter-and intra-specific competition for food among different species and age classes, ANOVA highlighted dynamic changes in inter-and intra-specific trophic level partitioning, while detrended analysis showed that the terrestrial environment is subsidizing the aquatic environment. Regression analysis showed that Schilbe intermedius diet was driven by discharge (F = 7.03; P = 0.045; R 2 = 0.58) while that of Marcusenius macrolepidotus was driven by water depth (F = 25.88; P = 0.04; R 2 = 0.93). Conclusion.The terrestrial-aquatic ecotone is important in fish growth of seasonal floodplains. Energy uptake is optimised through cannibalism to ensure species survival. Furthermore, species inter-relations are dynamic due to variations in food availability driven by seasonal flooding, which shortens and lengthens the food chain periodically. This dynamic relation is pronounced at low floods when predation and competition increases within the fish community. The evidence from this study has shown that predation, cannibalism, inter-and intra-specific competition are regulating factors in floodplain fish communities, driven by seasonal flooding.
