“…Jowett et al (1996) and Williams et al (2003) reported for New Zealand and USA respectively that the variation in fish densities observed in different streams was explained by differences in the environmental variables at a basin-level. Similarly, Moyle et al (2003) observed a strong association between fish densities and the strategies of fish stock management in the Cosumnes River basin (USA), whereas Menni et al (2005) reported that environmental constraints overruled fish assemblages in Northwest Argentina. Our results revealed that, at a regional scale, the fish assemblages were primarily determined by watershed features like altitude and catchment area, and the land use effects (exotic forest and pasture).…”

“…It is well known that introduced species influence freshwaters systems at the individual, population, community, and ecosystem levels (Moyle et al, 2003;Penaluna et al, 2009). At a population level, several authors reported that salmonids are among the main predators and food/habitat competitors of native fish, thus strongly influencing the structure of their populations and their patterns of distribution (Cussac et al, 1997;Macchi et al, 2005;Penaluna et al, 2009).…”

“…Fish are frequently the focus of stream studies since they have economical value and, in relatively undisturbed environments, they can be good indicators of stream and watershed conditions (Moyle et al, 2003). The understanding of the relationships among landscape, stream characteristics and fish assemblages has thus motivated several studies (e.g.…”

-We assessed the effects of land use on the structure of stream fish assemblages in Northwest Patagonia, Argentina. To this end, a total of 18 sites distributed in 15 streams were sampled during the low water period. At each site, 26 regional and local scale variables were used to describe the environmental conditions. The macroinvertebrate density, and the composition and abundance of fish were then recorded. Statistical associations between local assemblage structures and environmental variables were quantified by canonical correspondence analyses. The results revealed that, at a regional scale, the fish assemblages were primarily determined by watershed features like altitude and catchment area, and by land use effects (exotic forest and pasture). Assemblage compositions were also related to some local-scale features such as water velocity, food availability (density of benthic macroinvertebrates), instream characteristic and riparian features. Also, the observed fish species richness was low. Overall, exotic salmonids largely dominated in the samples both in numbers of individuals (98.9%) and in biomass (99.9%), whereas native fish (Hatcheria macraei and Odontesthes hatcheri) were scarcely represented. Rainbow trout (Oncorhynchus mykiss) was the most abundant fish, and was present in all streams. Native species were restricted to five streams located in the ecotone between the Andes and the steppe, where salmonids were also present. Salmonids were the only fish at Andean streams which suggest the existence of a strong geographic segregation between native and exotic species. Some aspects related to the incidence of the introduced species in the structure of fish assemblages are discussed.

Abstract-A total of 1 124 adult and juvenile individuals, representing 35 species from 13 families were collected in the four rivers of Johor. Each river represents a different of land use; Sungai Mengkibol is an urban river, Sungai Madek is associated with logging activities, the downstream section of Sungai Dengar for agricultural activities and it's middle section which is located at the foot of Gunung Berlumut as a reference station under pristine forest condition. The families represented in the samplings was dominated by Cyprinidae with 20 species (54.29%), followed by Mastacembelidae with three species (8.57%), Channidae and Hemiramphidae with 2 species each (5.71%). The other families were represented by one species each from Bagridae, Cichlidae, Claridae, Cobitidae, Gobiidae, Loricariidae, Poecilidae, Sisoridae and Synbranchidae(2.86% each). The highest number of fish were collected at Sungai Dengar station (376 individuals) followed by Sungai Ulu Dengar (306 individuals), Sungai Madek (238 individuals) and Sungai Mengkibol (204 individuals). Although the number of fish among the rivers were not statistically different (p = 0.138, p > 0.05), species diversity was significantly different according to river characteristics. Sungai Ulu Dengar has the highest number of species with 22 species, followed by Sungai Dengar with 21 species and Sungai Madek with 19 species. The lowest number of species was recorded at Sungai Mengkibol with 11 species. Water quality parameters like dissolved oxygen, turbidity and temperature show positive correlation with the species diversity. Therefore, it can be concluded that healthy river support high diversity of fish species.

“…The goals of this study were to document fish assemblage change over the period of record and assess the possible causes. We were particularly interested in the abundance of nonnative piscivores because they may influence fish assemblages (e.g., Lemly 1985, Fletcher 1991, Moyle et al 2003, Gard 2004). …”
