摘要: Shyi-Liang Yu and Edward J. Peters (2002) Diel seasonal habitat use by red shiner (Cyprinella lutrensis). Zoological Studies 41(3): 229-235. Fish distribution microhabitat were quantified over a 24-h period 15 times from July 1988 to October 1990 at site in the lower Platte River, Nebraska. The objectives of this study determine effects availability on lutrensis) describe variations depth, velocity, cover, substrate diel periods. Day-night collections showed difference selection or avoidance depths substrates summer. Red shiners selected less than 30 cm during night fine day summer, avoided 60 coarse consistently slow water ( cm/s) both summer fall. Results suggest that current velocity is major factor affecting distributions River. http://www.sinica.edu.tw/zool/zoolstud/41.3/229.pdf
