Abstract

Presence-absence and abundance of each fish species in a river habitat depend on several factors and they prefer a specific range of each habitat factor. The present study was carried out to investigate the Habitat Suitability Index of Capoeta razii and the effect of habitat factors on its distribution and abundance in Roodbabol branch of the River Babolrood (Mazandaran Province). To do, fish sampling was performed at 20 sampling stations during the last two weeks of December 2017 and 11 habitat factors were measured at each sampling station. During the whole period, sampling was performed once at each station. Then, habitat suitability curves for each factor and suitability index of each station were obtained using HABSEL software. Also, the determination of the distribution pattern of C. razii and its relation with the best habitat factors were surveyed using dbRDA analysis according to its abundance at each station in Primer+Permanova (Ver. 6). Based on the HABSEL results, C. razii inhabiting Roodbabol prefers wide locations with low water flow speed, temperature between 14 to 18° C, average depth (22 to 30 cm), average altitude (140-180 m), average EC (260-300 μ S/cm), small grain size of substrate rocks (100-125 mm), high level of dissolved oxygen (12 to 13 mg/l), and average salinity (1. 5-1. 7 mg/l) which are covered by bush and shrubs and the shadow level is 41-70%. Also, dbRDA graph-based on DistLm model indicated that factors of depth and width in the first order and water flow with EC in the second order affected the abundances differences of C. razii among various stations.
