Abstract
The aim of this article was to some morphometric characteristics of Rhodeus amarus from Dinsiz Stream. A morphological analysis of 21 morphometric characters were done. These characteristics total length (TL); fork length (FL); standard length (SL); predorsal length; dorsal fin base length; dorsal fin length; head length; pretorbital length; eye diameter; postorbital length; interorbital distance; body height; preanal distance; anal fin base length; anal fin length; pectoral fin base length; pectoral fin length; ventral fin base length; ventral fin length; caudal peduncle depth and weight (W). The samples were measured weight to the nearest 0.01 g and total, fork and standard length to the nearest 0.01 mm. The total length (TL) and weight (W min-max) of the fish were 4.2- 7.1 cm and 1.699- 7.444 g, respectively.Keywords: Rhodeus amarus; European bitterling; morphometric properties; Dinsiz Stream Turkey
Highlights
Rhoeus amarus (Bloch, 1972) has a wide distribution throughout Europe, where it inhabits a range of standing and slow-flowing habitats (Przybylski & Zieba, 2000; Kottelat & Freyhof, 2007)
The present study examines biological properties of Rhodeus amarus from Dinsiz Stream
The relations between total length (TL) and weight (W) for most species of fishes can normally be represented by the "length-weight relationship" following equation: W = aTLb
Summary
Rhoeus amarus (Bloch, 1972) has a wide distribution throughout Europe, where it inhabits a range of standing and slow-flowing habitats (Przybylski & Zieba, 2000; Kottelat & Freyhof, 2007). Life expectancy is exceptionally up to five years, but most individuals do not survive in their first reproductive years and the population sizes change drastically over the years (Kottelat & Freyhof, 2007) It is most abundant in wet vegetation and sand silt bottom, lowland ponds, canals, slow-flowing rivers, singles, and still or slow-flowing waters with oxbows and mussels (Kottelat & Freyhof, 2007). It is found among plants in shallow waters, on the sand and muddy bottoms. The present study examines biological properties of Rhodeus amarus from Dinsiz Stream
