Abstract.Over the last decade there has been a major rise in the number of attempts at fish conservation and management as a response to the widespread degradation of aquatic ecosystems. The assessments involved are rarely planned and executed with inputs from the species’ life history, particularly their microhabitat use over space and time. The seasonal and size related microhabitat use of two critically endangered cyprinids – the Iberian nase Iberochondrostoma almacai and Iberian chub… 
Structural microhabitat use by endemic cyprinids in a Mediterranean‐type river: Implications for restoration practices
Endemic freshwater fish from the Mediterranean region are among the most threatened species in the world owing to increasing river degradation. Because of such threats, the number of river
Habitat patchiness affects distribution and microhabitat use of endangered Mira chub Squalius torgalensis (Actinopterygii, Cypriniformes)
It is suggested that, in low flow conditions, chub respond to resource patchiness by congregating in favourable microhabitats, and that maintenance of mosaics of patches with variable substrata, cover and depth may be important for the persistence of fish in Mediterranean streams.
Ontogenetic dietary shifts and food selection of endemic Squalius carolitertii (Actinopterygii: Cypriniformes: Cyprinidae) in River Tormes, Central Spain, in summer
The Northern Iberian chub, Squalius carolitertii (Doadrio, 1988), is a small endemic cyprinid inhabiting the rivers of the Iberians Peninsula across a large area, including the Douro, Mondego, Lima, Minho, and Lérez basins.
Defining critical habitat conditions for the conservation of three endemic and endangered cyprinids in a Mediterranean intermittent river before the onset of drought
The results of this study provide the first detailed report of the habitat use of three endemic and endangered Greek cyprinids and highlight the importance of deep habitats that must be preserved as refugia while the drought events progress.
Assessment of instream structures for habitat improvement for two critically endangered fish species
The number of fish habitat improvement schemes has greatly increased in response to the widespread degradation of aquatic ecosystems. However, many of these enhancement projects often fail to create
The importance of structural features for spawning habitat of nase Chondrostoma nasus (L.) and barbel Barbus barbus (L.) in a pre-Alpine river
It is demonstrated that efficient river restoration requires re-establishing riparian vegetation besides hydromorphological habitat improvements in order to provide adequate spawning grounds for nase and barbel in the Pielach River.

Common name: Escalo do Arade (Portuguese). Conservation status: Critically Endangered according to the Portuguese Red Data Book (Cabral et al. 2005). Identification: Small cyprinid with 131mm of

Habitat selection and foraging success by an endangered Mediterranean cyprinid: implications for habitat restoration
Investigation of how water velocity, body size and intra-specific interactions influence habitat selection and foraging success by the highly endangered Mira chub Squalius torgalensis suggests restoring low and moderate velocities up to 26 cm/s will help ensure suitable habitat and improve the fitness of small and large chub occurring in interacting groups.
Cyprinid passage performance in an experimental multislot fishway across distinct seasons
New engineering solutions are required to minimise the effects of an increasing number of anthropogenic barriers on watercourses. Longitudinal connectivity must be provided through fishways to allow


Microhabitat use by Iberian nase Chondrostoma polylepis and Iberian chub Squalius carolitertii in three small streams, north‐west Portugal
–  Microhabitat use of Iberian nase Chondrostoma polylepis (Steindachner 1865) and Iberian chub Squalius carolitertii (Doadrio 1988) was studied in three small streams of the Lima basin, north-west

Several field observations of predation threat, particularly during the period of reduced discharge (which reduced the amount of cover), suggest that predation risk may influence the microhabitat use of young fishes.
Microhabitat use by fish in the lower Rio Matarraña, Spain, 1984–1987
Microhabitat use in Barbus graellsii, Cyprinus carpio, Chrondostoma toxostoma, Esox lucius, Gobio gobio and Leuciscus cephalus during 1984–1987 in the lower Rio Matarrana, Spain was quantified and Canonical analyses of discriminants and univariate data demonstrated that the distance from the substratum was the best predictor of interspecific differences in microhabitats use.
Seasonal abundance and microhabitat use of bullhead Cottus gobio and accompanying fish species in the River Avon (Hampshire), and implications for conservation
Bullhead conservation status is discussed, in particular the possible exemption of British bullhead populations, such as already granted for those of Finland, from Annex II of the Habitats Directive.
Feeding ecology and habitat of the threespine stickleback, Gasterosteus aculeatus microcephalus, in a remnant population of northwestern Baja California, México
The feeding strategy of the threespine stickleback shifted from opportunist in winter to specialist in spring and between sexes for most sampling months.
Microhabitat use and diet of 0+ cyprinid fishes in a lentic, regulated reach of the River Great Ouse, England
It is suggested that this habitat offers increased growth rate, reduced predation risk and increased food abundance to all species, and that species overlap is due to complementary habitat use rather than aggregation.
Spatial and ontogenetic variability in the microhabitat use of stream-dwelling spined loach (Cobitis taenia) and stone loach (Barbatula barbatula)
Water velocity and filamentous algae were the most influential microhabitat variables, the latter decreasing in importance with increasing age of both fish species, and preferred water velocities generally decreased with age in spined loach and increased in stone loach, with substratum size generally increasing with fish age in both species.
Composition and spatial organization of fish assemblages in the lower Guadiana basin, southern Iberia
The lower Guadiana fish community changed in space from assemblages characterized by the high relative abundances of Leuciscus pyrenaicus, smaller size-classes of Barbus spp.
An analysis of otter Lutra lutra predation on introduced American crayfish Procambarus clarkii in Iberian streams
Otter populations inhabiting Iberian streams may still be limited by indigenous prey species, such as cyprinids, which make up the bulk of the diet in late autumn and winter, even in areas holding abundant populations of introduced American crayfish.
Spatial heterogeneity in roach (Rutilus rutilus) diet among contrasting basins within a lake
Habitat and diet variation of roach were studied in Lake Banyoles (Spain), an oligotrophic karstic lake with strong spatial heterogeneity in food resources, and roach displayed an ontogenetic shift from zooplanktivory to benthivory.
