“…The distribution of Fundulus heteroclitus in the Atlantic coast of North America or in southwestern Iberia (where it was introduced and dispersed to different river estuaries) and Aphanius spp . along Mediterranean salt marshes exemplifies that despite the likely absence of long‐distance movements through salt waters in modern times (Moyle & Cech, 2004), the distribution patterns of such secondary species are very different from primary fishes, which are often confined to a few river basins.…”

Aim: Unravelling the ecological and historical factors that underlie species distributions has challenged ecologists for a long time. Thus, our objective is to understand the role of environmental variables explaining the distribution of three major ecoevolutionary groups of inland fishes (Darlington's divisions: primary, i.e. strict freshwater; secondary, i.e. salt-tolerant; and peripheral, i.e. diadromous and marine origin), and how these variables are related to fish traits.Location: Iberian Peninsula.Taxon: 51 native and 17 alien inland fish species from the Iberian Peninsula. Methods:We modelled distributions of the most common inland fish species across the Iberian Peninsula to compare the importance of different predictors among the three Darlington's divisions and between native and alien species. To explore the importance of specific environmental variables in determining the distribution of different traits of inland fish, variable importances obtained from species distribution models were subjected to a redundancy analysis.Results: Darlington's divisions differ significantly in salinity tolerance, in distribution overlap, in the importance of distribution predictors and associated life-history traits. Topographic and climatic variables were generally more important than land use and anthropogenic factors in explaining fish distributions. We found significant differences in the importance of variables explaining the distribution of native vs. alien species and especially among Darlington's divisions. River basin was most important for primary native and many alien species. Increasing mean temperature and damming were positively associated with the presence of tolerant, large-bodied and warm-water alien species from more hydrologically stable habitats.Main conclusions: Despite marked differences in the distribution patterns of native and alien species, evolutionary and introduction histories as well as seawater tolerance are central factors explaining the current distribution of inland fishes. Darlington's divisions proved useful for addressing ecological and biogeographical questions at broader spatial scales.

“…The gills perform several functions in all fishes; the first and important function is that they serve as the main respiratory sites for gas exchange in all fishes (Mattingly, 1996; Moyle & Cech, 2004), while the secondary function is linked to feeding habits where the arrangement of the gill rackers and filaments were expressed the feeding habits of the fish (Fernandes, Castro, & Mazon, 2003; U. Kumari, Yashpal, Mittal, & Mittal, 2009). The Bagrus bayad 's gill system was shown to be embedded inside two‐gill chambers that communicated with mandible ventrally, oral, and pharyngeal cavities dorsally and closed by the operculum laterally.…”

The work under investigation is carried out to describe the gross morphology and ultrastructure of the gills of the species Bagrus bayad grossly and with the help of scanning electron microscopy. The current work carried on ten fresh adult Bagrus bayad. Bagrus bayad is a genus of the Bagridae family. Our results revealed that the operculum opened caudoventrally. The wide interbranchial septum consisted of four transverse raised areas on each side that connected by transverse lines caudal to the base of the tongue. The gill arch is divided into long ceratobranchial and the short epibranchial clearly and formed an angle between them in the first three gill arches but in the fourth-gill arch is not clear.The first two gill arches have only lateral rackers. The first arch carried well-developed long rackers while rackers on the following rows were short. The majority of gill rackers were short as an adaptation of the carnivorous feeding habit of the Bagrus bayad. The gill arch and rackers were covered by pavement cells with chloride and mucus cells. The pavement cell surface has numerous microridges giving them the fingerprint's appearance. The gill filament's length is nearly fixed along the entire gill arch. Along the gill arch, and the gill filament carried leaf-like gill lamellae. At higher magnification, the gill filament appeared covered by irregular polygonal cells that have concentric microridges.

“…Swimming capacity reflects a sacrifice between length and weight (Alexandre et al ., 2014), where the key component seems the energy reserve. Higher reserves imply not only an increase in mass that means worse hydrodynamics and greater resistance to movement (Boily & Magnan, 2002), but also better anaerobic metabolism and greater power (Moyle & Cech, 1996).…”

Water temperature and flow velocity directly affect the fish swimming capacity, and thus, both variables influence the fish passage through river barriers. Nonetheless, their effects are usually disregarded in fishway engineering and management. This study aims to evaluate the volitional swimming capacity of the northern straightmouth nase (Pseudochondrostoma duriense), considering the possible effects of water temperature, flow velocity and body size. For this, the maximum distance, swim speed and fatigue time (FT) were studied in an outdoor open-channel flume in the Duero River (Burgos, Spain) against three nominal velocities (1.5, 2.5 and 3 m s À1 ) and temperatures (5.5, 13.5 and 18.5 C), also including the changes between swimming modes (prolonged and sprint). Results showed that a nase of 20.8 cm mean fork length can develop a median swim speed that exceeds 20.7 BL s À1 (4.31 m s À1 ) during a median time of 3.4 s in sprint mode, or 12.2 BL s À1 (2.55 m s À1 ) for 23.7 s in prolonged mode under the warmest scenario. During prolonged swimming mode, fish were able to reach further distances in warmer water conditions for all situations, due to a greater swimming speed and FT, whereas during sprint mode, warmer conditions increased the swim speed maintaining the FT. In conclusion, the studied temperature range and flow velocity range influence fish swimming performance, endurance and distance travelled, although with some differences depending on the swimming mode. The provided information goes a step forward in the definition of real fish swimming capacities, and in turn, will contribute to establish clear passage criteria for thermo-velocity barriers, allowing the calculation of the proportion of fish able to pass a barrier under different working scenarios, as well designing of the optimized solutions to improve the fish passage through river barriers.
