摘要: Early autumn movements of johnny (Etheostoma nigrurri) and fantail (E. flabellare) darters were examined in a pool-riffle system. Of the 340 marked during study, only 3.24% (10) recaptured fish (N = 309) moved. Three hundred forty-one marked, 12.78% (17) 133) Over 75% all an upstream direction. Chi- square analyses indicated that restricted to areas near point initial capture. Density estimates pool-dwelling darter (0.80/m2) lower than those riffle-dwelling (5.59/m2). These results suggest population density habitat quality may influence seasonal stream fishes.
