Length-Weight and Length-Length Relationships of Alburnus mossulensis and Acanthobrama marmid (Heckel, 1843) in Karasu River (Turkey)

Öz

Bu çalışmada, Karasu Nehri’nin (Fırat Nehri kolu) 15 farklı istasyonundan yakalanan A. mossulensis ve A. marmid (Heckel, 1843)’in boy-ağırlık ve boy-boy ilişkileri belirlenmiştir. Ekim 2014-Eylül 2015 tarihleri arasında elektroşoker ile 228 A. mossulensis ve 365 A. marmid yakalanmıştır. Total boy-ağırlık ilişkileri A. mossulensis için W=0,0128L2,81 (r2=0,93); A. marmid için W=0,0055L3,30 (r2=0,97) olarak tespit edilmiştir. A. mossulensis’in tüm bireylerinde negatif allometrik ve A. marmid’te ise pozitif allometrik büyüme bulunmuştur. A. mossulensis’in boy-boy ilişkisi TB=0,3611+1,0737ÇB,  ÇB=0,3132+1,0549SB ve SB=0,0709+0,8325TB; A. marmid’in ise TB=0,2043+1,0767ÇB, ÇB=0,1062+1,0999SB ve SB=0,1125+0,8047TB olarak hesaplanmıştır.

Length-Weight and Length-Length Relationships of Alburnus mossulensis and Acanthobrama marmid (Heckel, 1843) in the Karasu River (Turkey)

Abstract

In this study, the length-weight relationships and length-length relationships were determined for A. mossulensis and A. marmid (Heckel, 1843)) collected in the 15 different site of Karasu River (Tributary of Fırat River). A total of 228 individuals for A. mossulensis and 365 for A. marmid were caught by electroshocker between October 2014 and September 2015. The total length-weight relationships were estimated as W=0.0128L2.81 (r2=0.93) for A. mossulensis and W=0.0055L3.30 (r2=0.97) for A. marmid. The types of growth for all specimens were found negative allometric for A. mossulensimarmid (Heckel, 1843)) collected in the 15 different site of Karasu River (Tributary of Fırat River). A total of 228 individuals for A. mossulensis and 365 for A. marmid were caught by electroshocker between October 2014 and September 2015. The total length-weight relationships were estimated as W=0.0128L2.81 (r2=0.93) for A. mossulensis and W=0.0055L3.30 (r2=0.97) for A. marmid. The types of growth for all specimens were found negative allometric for A. mossulensis and positive allometric for A. marmid. Length-length relationships were calculated as TL=0.3611+1.0737FL, FL=0.3132+1.0549SL and SL=0.0709+0.8325TL for A. mossulensis and TL=0.2043+1.0767FL, FL=0.1062+1.0999SL and SL=0.1125+0.8047TL for A. marmid.
