Ou River (Zhejiang) two alien species (Mozambique tilapia and largemouth bass); however, 34 species recorded in 1972 were absent in 2010, and overall fish density was lower. Goby "Pseudorhinogobius aporus" is endemic to the Ou River system: it is only known from a brook in the upper Ou River system. Ou River (Zhejiang) The Ou River () or Oujiang is the second-largest river in the Zhejiang province of eastern China. The river flows before finally reaching the city of Wenzhou and emptying into the East China Sea, into which it discharges of water annually. Shen Jiang (), Jiang Yongjia (), and Wenjiang ()
OU Andromedae a nearby giant planet, such as a hot Jupiter, since an infrared excess has been observed. Another explanation relies on its strong magnetic field; if OU Andromedae was an Ap star during its main sequence stage of evolution, so it could have retained both the strong magnetic field and the fast rotation of Ap stars. OU Andromedae is also a bright X-ray source, due to the activity of its corona; it's estimated that solar-like active regions cover 30% of the surface. This is another effect of the strong magnetic field, which produces an uninterrupted flaring activity that generates a large
