“…Whereas the roles of lateral and two-way migrations of fish in floodplain areas have been studied (Fernandes, 1997;Hohausova´et al, 2003;Welcomme et al, 2006;Nunn et al, 2010;Makrakis et al, 2012), mass upstream migration of juveniles appears unusual. Even though upstream migrations of juvenile fish have been occasionally documented (Yuma et al, 2000;Beckman and Larsen, 2005;Urabe, 2006), their mechanisms and adaptive significance are unclear. We are also unaware of any study reporting so large-scale upstream migration of juvenile fish.…”

-Subarctic Siberian freshwater ecosystems are unique due to severe climatic conditions and strong seasonal changes of water supply, temperature and nutrient availability. In this work we evaluated the relative influence of the illumination level linked with the diurnal cycle, local environmental heterogeneity and water level changes during the receding flood on the distribution and migrations of fish in the Lower Irtysh basin. The data are based on hydroacoustic surveys conducted from boats in the main channel and long-term hydroacoustic recording from a stationary platform in a floodplain stream. The majority of the fish in the study area were represented by juvenile Cyprinidae. Illumination level is shown to have the strongest effect on fish density both in floodplain stream and near-surface areas of the main channel: fish tended to migrate at night and their density was always significantly higher at night. Effects of local ecological heterogeneity and the water level change were weaker: they affected the dynamic re-distribution of the fish. Daily reduction of the water level significantly influenced the intensity of fish migrations in a small floodplain stream, although with a 4 days lag. We suggest that the high environmental variability in lower Irtysh dampens local environmental effects on fish assemblages. Two-way (downstream and upstream) migrations of juvenile fish in a floodplain stream are documented, pointing the potentially important role of adaptive behavioural tactics.

“…In mid-September 2002, OR was collected at the littoral zones of Kaizu-osaki (21.8 mm Ϯ 3.1, 17.0-32.3 mm, n ϭ 39) and Ohmi-maiko (21.1 mm Ϯ 2.7, 17.2-27.4 mm, n ϭ 40). These OR never showed upstream-migrating behavior (in which individuals swim up in a group just above the river bottom; Yuma et al, 2000) even though August is the period of ascending rivers, suggesting that these individuals belonged to the lacustrine type (hereafter Lake-OR). Also in midSeptember 2002, OR was captured at an outlet of the Chinai River (18.7 mm Ϯ 1.3, 15.9-23.1 mm, n ϭ 38) and an outlet of a creek of Ohmi-maiko (18.9 mm Ϯ 1.5, 16.6-23.7 mm, n ϭ 40).…”

“…They reproduce in rivers in May to July, and the hatched larvae drift down into the lake (Hidaka and Takahashi, 1987). Larvae live in the open water of the lake for 1-2 months, and juvenile fish then ascend the river in a group from July to September (Yuma et al, 2000;Maruyama et al, 2001). Other Rhinogobius sp.…”

The freshwater goby Rhinogobius is the most abundant fish in the shore area of Lake Biwa, Japan. Recently, it has been reported that two morphs of Rhinogobius inhabit this lake. In this study, genetic variations in Rhinogobius sp. OR (Orange-type) and Rhinogobius sp. BW (Biwa-type) in the Lake Biwa water system have been investigated using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) analysis of mitochondrial DNA, including the variable D-loop region. Samples of Rhinogobius sp. OR were collected from the middle sites of three rivers, two outlets, and two lakeshore sites, whereas samples of Rhinogobius sp. BW were taken from two lakeshore sites. Rhinogobius sp. OR and Rhinogobius sp. BW did not share any haplotypes, suggesting that PCR-RFLP analysis is effective for distinguishing between these species of goby. The haplotype diversity of Rhinogobius sp. OR (0.214-0.543) was lower than that of Rhinogobius sp. BW (0.543-0.682). There were no significant differences in haplotype frequencies between Rhinogobius sp. BW groups from the two localities. In addition, haplotype frequencies in Rhinogobius sp. OR did not differ significantly among samples from the middle sites of rivers, the outlets, and the shores. These results indicate that in Rhinogobius sp. OR there is frequent gene flow among fish inhabiting different sites, and that this species of goby consists of a single population throughout the Lake Biwa water system.

“…Cowan et al (2000) concluded that, during the late-larval to juvenile stage, a reduction in prey resources due to high population densities is an important factor for cohort growth. Yuma et al (2000) noticed that, in the absence of predators, Rhinogobius sp. juveniles increase agonistic interactions by competing for space and food.…”
