Despite the increasing number of studies on systematics Stephanoberycoidei (bigscales, pricklefishes, gibberfishes, hispidoberycids, and whalefishes) globally, knowledge about diversity distribution group in western South Atlantic still remains fragmentary. In this study, we present new anatomical (meristic morphometric) distributional data for 18 species based examination 150 specimens recentl...

Aquatic animals play an important role in the energy flow and matter cycling in the wetland ecosystem. However, little is known about their effects on pollutant removal performance and microbial community in constructed wetlands. This work presents an initial attempt to investigate the effects of Misgurnus anguillicaudatus (loach) and Cipangopaludina cathayensis (snail) on nutrient removal perf...

The oriental weatherloach Misgurnus anguillicaudatus is an extremely ammonia-tolerant fish. Many ammonia-protection mechanisms have been reported in this fish. Six strategies used by this fish to deal with the problem of excess ammonia are described. The fish can (1) reduce ammonia production through reduction in protein and/or amino acid catabolism; (2) reduce ammonia production and obtain ene...

Fish passes facilitate fish movement in fragmented river systems, yet they can also provide important habitat functions. This study investigated the community composition of different constructed types (fluvial habitats, floodplain ponds) within relation to characteristics order deduce recommendations for fish-friendly designs such structures. structures differed significantly from those main r...
