“…Accordingly, the observed significant correlations between fish abundance and temperature resulted mainly from the stimulating effect of raising water temperature in spring for spawning migrations (Jonsson, 1991). However, telemetric studies of habitat use by barbel (Baras and Cherry, 1990), roach (Baade and Fredrich, 1998) and chub (Allouche et al, 1999) detected no significant correlations between temperature fluctuation and daily activity or movements. These findings correspond well to the observed heterogenous influence of short-term temperature variations on species abundance (Table II), but it seemed evident that correlations between decreasing temperatures and fish abundance were biased by gear efficiency.…”

Between June 1998 and May 2000 an adult fish sampling was carried out in the lowland River Oder using bottom otter trawls in the mid channel and electric fishing at the shorelines. This study focused on the lateral connectivity between mid channel and river margins with the aim to characterize the importance of mid-channel sections as fish habitat.Altogether 15 660 fish of 30 species were sampled, 8169 fish of 20 species in the mid-channel section and 7491 fish of 27 species at the shoreline. At the shoreline we observed significantly higher fish densities (345.4951.8 fish per 1000 m 3 compared to 5.291.0, mean9standard error) and numbers of species (11.19 0.5, respectively, 5.29 0.3). However, three species were exclusively in the mid channel and a further six more frequent there. The mid channel was dominated by silver bream (Abramis bjoerkna) representing 75.6% of the total catch. It was generally colonized by bigger fish (22.1 90.12 cm total length compared to 13.09 0.08 cm).According to the observed significant habitat preferences, we classified a guild of potamal species, which shift during their first year of life to mid-channel habitats and exhibited the highest relative abundance there. To this guild belong the following species: silver bream, common bream (Abramis brama), blue bream (Abramis ballerus), whitefin gudgeon (Gobio albipinnatus), zander (Sander lucioperca) and wels (Silurus glanis).

“…It could be the beginning of a new trend in the assemblage development or a delayed consequence of the huge flood in 1997. Fish might also use the backwater to a larger extent as an overwintering (Freyhof, 1997), feeding or other type of habitat/refuge (Allouche et al, 1999). Similarly, Černý et al (1997) recorded an increase in the fish abundance in backwaters of the lower Morava River within three years after their restoration, however, it was probably caused by the increase of their area.…”

ABSTRACT:The development of fish assemblage in a restored river backwater (Kurfürst backwater, Morava River, Czech Republic) was monitored over a six-year period from its restoration. The structure of fish assemblage remained similar throughout the years. Species richness of adult fish increased from twelve species during the restoration to 20 after it. Initially steady fish abundance (mean 52.3-98.1 inds/ha) and biomass (mean 5.8-7.6 kg/ha) increased significantly in 1999 five years after restoration (576.9 inds/ha and 23.3 kg/ha, respectively). The main resident species were pike Esox lucius, roach Rutilus rutilus, rudd Scardinius erythrophthalmus and perch Perca fluviatilis. High abundance of bleak Alburnus alburnus and chub Leuciscus cephalus was related to their spring spawning period. The structure of the 0+ fish assemblage was similar throughout the years, with chub and bleak prevailing during the restoration, and roach, chub and rudd after it. The number of 0+ species increased from seven to 17. The monitoring documented that the restoration could be considered as beneficial for the fish assemblage. Habitat development of the backwater is likely to influence its current value as a refuge, spawning site and nursery for local fish populations.

“…In response to such reports, some studies have either not recorded data from the period immediately after tagging (e.g. one week by Allouche et al, 1999) or excluded it from analyses to mitigate against the effects of tagging and handling on fish behaviour (Winter, 1996). Mesing and Wicker (1986) report unusual long-distance movements in largemouth bass during the first days of release after transmitter implantation.…”
