Length-weight relationship of two fish species from Cholvar River, western Iran: Mastacembelus mastacembelus (Banks & Solander, 1794) and Glyptothorax silviae Coad, 1981

Abstract

Summary Length–weight relationships have been determined for two species, Mastacembelus mastacembelus and Glyptothorax silviae. Samples were taken in 2011 from the Cholvar River in western Iran. It is believed that the size range covered is close to a commonly known size range of each species. The length–weight relationship values of b were determined as 2.66 for M. mastacembelus and 3.045 for G. silviae. However these data are based on preserved specimens, and a correction factor for live lengths and weights is still warranted.

Biological and morphological aspects of spiny eel Mastacembelus mastacembelus (Banks and Solander, 1794) inhabiting Al-Tharthar canal / Samarra, Iraq

“…Gumus et al (2010) referred that the regression coefficient was 2.84 for M. mastacembelus from southern Anatolia, Turkey. Gerami et al (2014) found the growth regression coefficient for 32 fish (19.8-46.5) cm total length was 2.675 from Cholvar River in the Karun river basin in Iran, which is closer to find out. Wahab (2006) pointed that the condition factor of M. mastacembelus 0.23, also lower than one.…”

“…Some factors such as season, salinity, temperature, sex, fish health, food availability (including special/temporal distribution) may also affect the LWRs in marine species (Froese, ; Gerami et al., ; Lim et al., ). Moreover, the choice of sampling gear may affect the size range of the specimen captured, and thus the size range of ‘ a ’ and ‘ b ’ for the estimation of the LWRs.…”

Mastacembelus simack (Banks & Solander, 1794) Türünün Farklı Lokasyonlardaki (Dicle ve Murat nehirleri) Boy-Ağırlık İlişkisi ve Kondisyon Faktörü

“…The age and growth of M. mastacembelus, from south-eastern Anatolia were studied by Gümüş et al (2010). Then, Gerami et al (2013) reported on LWR of M. mastacembelus from Cholvar River, western Iran, and some biological properties including LWR of M. mastacembelus were reported from the upper Euphrates River Basin in Türkiye by Çoban et al (2021). Therefore, this study aimed to provide basic data and updated information about the LWR and condition factor for M. simack in two different water basins (Tigris and Murat rivers).…”
