Food Analysis of Hebius octolineatum and its Predation on Oryzias sinensis
Author of the article:CHEN Guozhu
Author's Workplace:National Plateau Wetland Research Center, Southwest Forestry University, Kunming 650224, China
Key Words:Hebius octolineatum; Oryzias sinensis; predation
Abstract:Food composition of the snake, Hebius octolineatum, was analyzed during April or May (before rainy season) from 2014 to 2016 in Dianchi Lake, Kunming city, Yunnan province. The results showed that 11 food types were detected. Especially, the endangered fish species, Chinese medaka (Oryzias sinensis), was found for the first time in the guts of three H. octolineatum (n=15). As the population of O. sinensis had significantly declined since the invasive mosquitofish (Gambusia affinis) was introduced, the effects of H.octolineatum predation on the dynamics of O.sinensis population need to be estimated.
