Some Growth Parameters of Capoeta umbla (Heckel, 1843) Population Living In The Pülümür River

Abstract

In this study, some growth parameters have been investigated like sex distribution, length and weight relationship, age determination, von Bertalanffy growth parameters and condition factor of Capoeta umbla (Heckel, 1843) (644 female, 743 male) captured from Pülümür River between 2017 and 2019. Females varied from 7.1 to 38.8 cm in total length and 3.4 to 514.2 g in weight. Males varied from 7.3 to 38.3 cm in total length and 3.5 to 450.4 g in weight. The sex ratio (females/males) for C. umbla was 1:1.154. The age groups for C. umbla was 0-11. The von Bertalanffy growth parameters were determined as Lt=49. 25[1-e -0.128(t+1.68) ]; Wt=666.91[1-e -0.128(t+1.68) ] 2.973 for female, Lt=44.42 [1-e -0.155(t+1.37) ]; Wt=735.19[1-e -0.155(t+1.37) ] 2.954 for male and Lt=45.29 [1-e -0.146(t+1.42) ]; Wt=772.56[1-e -0.146(t+1.42) ] 2.963 for all individuals. The growth performance index (Ф') value was determined as 2.476. The length and weight relations of C. umbla were found as W=0.0096*L 2.973 , R 2 =0.97 (95 % CI of b=2. 773-3.139) for females; W=0.0103*L 2.954 , R 2 =0.98 (95 %CI of b=2.797-3.092) for males and W=0.0100*L 2.963 , R 2 =0.98 ) for all individuals. The growth type of C. umbla was isometric for all individuals (R=0.99, R 2 =0.97, F1,1385=51700.4, P<0.001). The highest condition factor was observed as 2nd age (0.931), while the lowest was observed 11nd age (0.796).

Variation in the shape and size of the scale of the Tigris bream (Acanthobrama marmid, Heckel, 1843) from the Tigris River, Türkiye attributed to Seasonality, Age and Sex: A geometric morphometric study

“…Acanthobrama marmid plays a vital role in the ecosystem as a prey species for larger predatory fish and an important component of the food web. In rural areas, the local population consumes it [5].…”
