Growth parameters of invasive gibel carpCarassius gibelio(Bloch, 1782) in Lake Marmara (Turkey)

Abstract

The objective of this study was to determine growth parameters, such as age–length and length–weight relationships, as well as condition factors and sex ratio, of the Carassius gibelio (Bloch, 1782) population in Lake Marmara (western region of Turkey), which is one of the most important fishing areas. Fish were caught on a monthly basis by gillnets and trammel nets (mesh size 10–50 mm) between March 2012 and February 2013. A total of 1058 specimens (809 females and 249 males) were examined. The female–male ratio was 1:0.31. The maximum age was determined as VI and V for females and males, respectively. The total length of females and males ranged from 10.0 to 27.5 cm and from 10.2 to 24.0 cm, respectively. Their weight varied from 17.1 to 378.4 g and from 17.7 to 244.9 g, respectively. Length–weight relationship parameters were a = 0.014 and b = 3.040 for females and a = 0.015 and b = 3.039 for males. Von Bertalanffy growth parameters of the C. gibelio population were as follows: L∞ = 35.86 cm, k = 0.189 year−1, t0 = −1.238 years. Minimum and maximum condition factors were 1.56 for females in October and 1.82 in May and 1.67 for males in September and 1.94 in January.

Determination of some biological characteristics of Prussian carp (Carassius gibelio): the example of Bafra Balik lakes (Türkiye)

“…On the contrary, the a value in different studies conducted in the same lakes was higher than the current study [19,27,29,33,37,42,44,45,47,48,57,58] . The b value calculated in this study higher than the b value of C. Gibelo studied in Danube River, Bafra Dam, İkizcetepeler Dam, Gelingüllü Dam, Seyitler Dam, Büyük Menderes basin, Beyşehir and Marmara Lake [52,51,58,48,27,47,44,45,57,33] . The length-weight relationship parameters can be affected by factors such as sampling period, nutritional status, heightweight distribution, reproductive period, age, and gonad maturity.…”

An ichthyofaunal amendment with the length-weight relations and condition factors of some endemic and invasive freshwater fishes from Western Anatolia

“…The LWRs of the invasive species found from the Gediz River`s different water resources changed respectively between b = 3.023 from Marmara Lake and b = 4.347 from Demirköprü Reservoir for C. gibelio; and b = 3.423 from Demirköprü Reservoir and b = 3.921 from Marmara Lake for A. boyeri (Güçlü, Küçük 2021). In another study, the b value was found to be b = 2.965 (for combined sexes) for C. gibelio species from Marmara Lake (Ilhan et al 2020). In the current study, the b value of C. gibelio was found to be b = 2.914 from Akgöl Lake.…”

New Distribution Data for Prussian Carp Carassius gibelio (Bloch 1782) in the Middle Black Sea Region of Turkey

“…The existence of C. gibelio in Turkish inland waters was first reported in Lake Gala in 1986 (Baran and Ongan, 1988). The rapid spread of invasive species in Turkish inland waters was reported in many studies which led to a negative impact on native species and local habitats (İnnal and Erk'akan, 2006;Tarkan et al, 2012b;İlhan et al, 2020). In a few studies, C. gibelio was previously reported in the Middle Black Sea Region (Yılmaz et al, 2012;Bostanci et al, 2016;Macun, 2018;Akbay, 2019).…”
