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 collected from the wetlands of central Yangtze River, in Wuhan, Hubei Province, China. Samples obtained May 2012 to January 2013. O. determined first time.
This study examined the effect of habitat types and ontogenetic stages on diet shift Coreius guichenoti (Sauvage Dabry de Thiersant, 1874), a critically endangered fish species. Based stable isotope analysis method, following was explored: variations in δ13C δ15N values, isotopic niche width four basal food sources (Mollusks, Macrocrustaceans, Aquatic insect larvae particulate organic matters (POMs)) among three essential (the spawning ground, natural riverine feeding nursery area, Three...
An explicit demonstration of the changes in fish assemblages is required to reveal influence damming on species. However, information from which draw general conclusions regarding insufficient because limitations available approaches. We used a combination acoustic surveys, gillnet sampling, and geostatistical simulations document spatiotemporal variations downstream Gezhouba Dam, before after third impoundment Three Gorges Reservoir (TGR). To conduct hydroacoustic identification individual...
The Chinese sturgeon (Acipenser sinensis) is an anadromous fish inhabiting the Yangtze River. Migration of from estuary to upper River was blocked by Gezhou Dam, completed in 1981, and a new, much smaller, spawning ground established below dam. However, Three Gorges Dam began operating 2003, altering hydrological conditions new grounds impact on reproduction severe. annual survey shows that both scale breeding population decreased during this period. To illustrate sturgeon, habitat...
The primary objective of this investigation was to study the effect altitude on fish swimming ability. Different species were tested ensure that differences observed are not associated with a single species. Fish critical speed and burst determined using stepped-velocity tests in Brett-type respirometer. Based effects water temperature dissolved oxygen, it is clear ability decreases as increases. Further, because high physiology go beyond lower we recommend be at an similar target fishway...
Abstract Impoundment of the Three Gorges Reservoir (TGR) and overharvesting are anthropogenic factors that have had a dramatic effect on Yangtze fish. This study used multivariate analysis to quantify relationship between abiotic alterations (seven variables from TGR impoundment fishing activities) fish response, revealing processes through which changes affect assemblages over 14‐year period (1999–2012). Fish temporally clustered into three groups were strongly associated with impoundment....
2006年8月16-18日通过使用回声探测仪(Simrad公司EY60型,200kHz换能器)对青海湖的鱼类资源进行了探测评估.结果表明:青海湖裸鲤(Gymnocypris przewalskii)水平分布具不均匀性,有小型鱼群聚集现象;在不同的设定分区,鱼类密度在0.168-12.8ind./1000m<sup>3</sup>之间,均值为1.16ind./1000m<sup>3</sup>;布哈河口鱼类较为密集,密度最大值为12.8ind./1000m<sup>3</sup>.初步估算青海湖裸鲤达可捕规格(体长大于20cm)个体数量为6.5×10<sup>7</sup>ind.,95%置信度区间为35.6×10<sup>7</sup>-118.4×10<sup>7</sup>ind.,应用资源密度体积法估算青海湖裸鲤的可捕资源量约为15275t.探测实验还证实,EY60回声探测仪在青海湖中进行鱼类资源评估时探测效果良好,分析软件Sonar5可以对鱼类个体自动识别、计数,便于进行鱼类资源量评估.;A SIMRAD EY60 echo-sounder with 200kHz...
Eco-operation experiment by the Three Gorges Reservoir was carried out ten times to facilitate spawning of four major Chinese carps in lower reaches Yangtze River, from 2011 2017. To get knowledge fish response man-made flood process, and also assessing positive effect eco-operation on spawning, eggs were monitored daily drift-net method, a fixed profile Shashi reach between mid-May mid-July each year. Basing consecutive data research for seven years, practice effectiveness TGR summarized...
Hydroacoustic surveys were performed to clarify the density and spatial distribution of fish upstream downstream Changzhou Dam in Pearl River, China, with regard condition spillways. Fish densely distributed forebay dam average was 0.22 individuals/<TEX>$m^3$</TEX> under open spillways on 24 June 2010, but when closed 25 dispersed decreased 0.007 individuals/<TEX>$m^3$</TEX>. Meanwhile, region 0.28 before spillway opened May it 0.08 26 June, just after closed. The vertical not consistent....
