“…In our study, the abundance of this small armored catfish was higher in turbid conditions and further favored by warmer waters with higher concentrations of dissolved oxygen. A positive relationship between abundance of Siluriformes species and water turbidity was also found in temperate shallow lakes of Argentina (Rosso et al, 2010) and in several freshwater ecosystems of Bolivia, Venezuela and Brazil (Pouilly & Rodríguez, 2004).…”

“…Eutrophication is as a strong driver for fish assemblage structure in freshwater ecosystems (Van de Bund & Van Donk, 2002;Granzotti et al, 2018). Generally, it could be expected that vision oriented fishes prevail in clear oligotrophic waters, as most Characiformes, whereas chemo or tactileoriented fishes, as most Siluriformes, domain in turbid eutrophic conditions (Pouilly & Rodriguez, 2004;Rosso et al, 2010). Both B. iheringii and C. interruptus are small invertivorous Characiformes usually consumed by larger fish.…”

“…These differences have been largely attributed to the refuge provided by the aquatic vegetation in clear-water systems and by the negative effect of turbidity on fish species that use vision to detect their prey affecting predator-prey interactions (Chambers et al, 1999). Indeed, even narrow ranges in water transparency, traditionally neglected as important factors for fishes, may be still important for some species in highly turbid waters (Rosso et al, 2010).…”

Aim We evaluated the longitudinal patterns in distribution of native and non-native fish species in a hydrologically fragmented and environmentally variable lowland temperate river. Methods Four sites representing contrasting habitat and environmental conditions were sampled: a clear water reservoir, a turbid water lagoon and two river reaches with clear and turbid waters each. Environmental variables were measured in situ and in the laboratory. Fishes were sampled using trammel and beach seine nets. Results Two main environmental scenarios were identified: the upstream reaches, with colder, clearer and nutrient-oxygen poor waters (reservoir and its downstream river) and the downstream reaches, where turbidity, dissolved oxygen, water temperature, conductivity and nutrients largely increased (lagoon and its downstream river). Fourteen species with a high non-native/native (4:10) ratio were collected. Non-native species (NNS) were confined to lentic conditions, where the silverside Odontesthes bonariensis dominated. Native species (NS) better thrive in lotic conditions where the turbid scenario further favored tolerant species. Environmental conditions also seemed to influence the distribution of NNS. Fish assemblage structure considering either, all species, NNS or NS significantly differed among sampled reaches and habitat (lentic-lotic) conditions. Total fish abundance was higher in lentic reaches. Species richness and diversity were favored by the turbid scenario. Beta diversity was mostly explained by the replacement component revealing the substitution of species as the main pattern of variation. Water conductivity, nitrates and dissolved oxygen were the most important predictor variables in the best and most frequent explanatory models of fish assemblage structures. Conclusions Our results revealed that a low diversified Neotropical fish fauna is disrupted by habitat fragmentation due to the creation of artificial impoundments and the introduction of NNS. Environmental conditions further modulate the fish assemblage structure by affecting the distribution of species where tolerant species were favored by turbid, nutrient-rich waters with higher conductivity and pH.

“…Wolter and Arlinghaus (2003) suggested a navigation bottleneck hypothesis (NBH) in which they mainly focused on chronic physical water movement which exceeds the fish's swimming ability to counteract (Killgore et al 2001;Gutreuter et al 2003). Navigation also increases water turbidity (Kucera-Hirzinger et al 2009), where chronic turbid water affects growth and survival rate (Sutherland and Meyer 2007;Rosso et al 2010) as well as other behaviors such as feeding (Kano et al 2011) of fish individuals. Macrophytes are also impacted by navigation activities, which, in turn, affect their ecological functions as fish habitats and shelters (Willby and Eaton 1996).…”

Chinese freshwater fish numbers are over 1000 species, and at least 717 species in 33 families inhabit rivers, and another 66 species spend part of their lives in rivers, while others are mainly confined to estuarine reaches but occasionally swim upstream. Information on freshwater fish biodiversity in the Yangtze River basin was synthesized. Three hundred sixty-one species were found in the basin, of which 177 species are endemic to the Yangtze River and 25 species are categorized as endangered on the China Red Data Book for fishes. Around 80 % of the species (including 124 endemics) in the Yangtze River occur in its upper course above the Three Gorges Dam. As to species richness patterns along the altitude gradient, non-endemic and endemic fishes were different. Non-endemic richness showed a significant decrease with increasing elevation, whereas endemic richness had two peaks including a major peak around 500 m and a minor peak near 1800 m. Species density had two peaks at mid-elevation zones for endemic and non-endemic fishes, such as 1500-2000 m and 3500-4000 m for endemic fishes and 500-1000 m and 3500-4000 m for non-endemic fishes, respectively. In addition, the structure of endemic fish assemblages in the upper Yangtze River was highly correlated with local topographic and geomorphic characteristics.The combined effects of pollution, habitat degradation, and overexploitation have reduced fish stocks dramatically. Hydrological alterations are perhaps the largest threat to fish biodiversity in the Yangtze River basin, such as dam construction and disconnection between the river and its lakes. Conservation measures which were applied currently to protect the fish biodiversity in the basin exert ineffectively, such as nature reserve establishment, artificial propagation, and releasing. Therefore, in order to preserve fish biodiversity more effectively in this area, reserve networks, rather than a single national nature reserve, should be

“…Qinzhou Harbor is the second largest habor in South China, which supported 56.22 million tons of goods transported in 2012 which increased in an average of 36% in the last five years (Chen, 2014). Continually terminal operation and navigation would impact natural fish composition (Kano et al, 2013;Rosso et al, 2010). Moreover, the largest aquaculture for Ostrea rivularis in China is located in the mangrove of Qinzhou Harbor resulted in eutrophication and water acidification (Qiu, 2014), which caused decrease in fish diversity.…”

The composition and temporal variation of fish assemblages were investigated in the mangrove of Qinzhou Harbor, Guangxi Province, China from October 2011 to September 2012. A total of 67 fish species belonging to 57 genera, 32 families and 12 orders were collected. The Gobiidae (23.9%) were the most species-rich families, and the dominant species were Acentrogobius viridipunctatus and Bostrychus sinensis. Species richness, total abundance, total biomass and individual species abundance or biomass for the numerically abundant fish species were significantly different seasonally, such as abundance and biomass for A. viridipunctatus, B. sinensis, Glossogobius giuris, Acanthogobius hasta, Gerres limbatus, Sillago sihama, Lateolabrax japonicas, Moolgarda cunnesius and Leiognathus brevirostris. The Non-metricMultidimensional Scalings (NMDS) ordination showed a clear separation of fish samples with an anticlockwise direction for different sampling months, which indicated a gradual change in fish assemblages over the months. Results of two-way ANOVA showed fish species richness, total abundance and total biomass were significantly affected by tidal type in the mangrove of Qinzhou Harbor. However, NMDS ordination showed an unclear separation of fish samples between spring tide and neap tide. One-way ANOSIM further revealed no significant effects of tidal type.
