This study quantified and compared hypoxia tolerance and swim performance among cyprinid fish species from rapid-, slow- and intermediate-flow habitats (four species per habitat) in China. In addition, we explored the effects of short-term acclimation on swim performance, maximum metabolic rate (M(O2,max)) and gill remodelling to detect habitat-associated patterns of plastic response to hypoxia...

Fish personality traits, such as swimming activity, or personality related emergent behavioural properties, such as the degree of space use shown by an individual fish, should affect encounter rates between individual fish and fishing gear. Increased encounters should in turn drive vulnerability to capture by passively operated gears. However, empirical evidence documenting a relationship betwe...

Scanning electron microscopy (SEM) has been widely used to describe interspecific differences in egg quality of teleost freshwater fish, but potential intraspecific are poorly studied. Eggs many rheophilic cyprinids covered with adhesive structures such as attaching villi facilitating attachment at substrates spawning grounds high currents. Recent findings indicate that the cyprinid common nase...

The Rokel River (RR) basin is one of the most neglected ichthyofaunal basins, despite potential for undetected diversity and high levels endemism. Data on molecular phylogeny freshwater fish from this river are rare. Morphological features alone inadequate precise species identification. Here, a phylogenetic analysis performed based mtDNA Cytb gene eleven cyprinid RR recovered distinct lineages...
