Abstract
In this study, a total of 109 specimens (57 female and 52 male) of Salaria fluviatilis were captured by tulle net and scooped net between October 2017 and March 2018 from the Asi River system, Turkey. The length-weight relationship was W =0.0013L3.054 (r²= 0.967) for both sexes with isometric growth. The values of the exponent b of the length-weight relationships (LWRs) were 3.055 for females and 3.052 for males. The b values for females, males, and both sexes were not significantly different from 3.0 (P>0.05). Fulton condition factor (CF) was calculated 1.3955±0.034 for females, 1.4495±0.042 for males and 1.4212±0.027, for both sexes. Estimations of LWRs and CF for both sexes of S. fluviatilis, captured from Asi River, were provided for the first time.
Highlights
The freshwater blenny Salaria fluviatilis (Asso, 1801) is a member of the family Blenniidae and is well-known in the Mediterranean Region
The sex ratio of S. fluviatilis in the Asi River was slightly different from those in these previous reports, but females are dominant than males
The present study provides the first reference on length-weight relationships (LWRs) and condition factor (CF), of S. fluviatilis
Summary
The freshwater blenny Salaria fluviatilis (Asso, 1801) is a member of the family Blenniidae and is well-known in the Mediterranean Region. S. fluviatilis a common inhabitant of stony and gravel bottoms of rivers and brooks (Bath, 1986). It is generally preferred rubble and gravel substrate. Adults feed on small benthic organisms such as small snails and shrimps, and all kinds of insect larvae (Wilson, 2009). This species can reach up to 15.4 cm in total length (Laporte et al, 2012), and the maximum age is 5 (Kottelat and Freyhof, 2007).
