  The microhabitat preference of zebrafish, Danio rerio from Karala river was investigated. The availability/ preference of microhabitat variables such as (i) distance from the stream bank (ii) water column depth (iii) mesohabitat (iv) water velocity (v) substratum and (vi) subaquatic vegetal cover were quantified based on underwater observations covering a total of 400 m2 of stream area. Microhabitat selectivity was analyzed by comparing the microhabitat availability in the study site and the microhabitat used by fish. Data availability and microhabitats usage pattern were used for calculating habitat availability/preference of D. rerio. In order to test the microhabitat preference of D. rerio the Principal Component Analysis (PCA) and Canonical Correspondence Analysis (CCA) were applied. In PCA the first three components with higher Eigenvalue acc.. View More»
