Length-weight relationships for four small fish species caught in wetlands of central Yangtze River, China

Abstract

Length–weight relationships for four native species (Oryzias latipes Temminck & Schlegel, 1846; Rhodeus ocellatus Kner, 1866; Rhinogobius giurinus Rutter, 1897; and Micropercops swinhonis Günther, 1873) were determined. The fish were collected from the wetlands of the central Yangtze River, in Wuhan, Hubei Province, China. Samples were obtained from May 2012 to January 2013. Length–weight relationships for O. latipes were determined for the first time.
