BÝNGÖL, MURAT NEHRÝ, SOLHAN DERESÝ'NDE YAÞAYAN [CAPOETA UMBLA ((HECKEL, 1843)] SÝRAZ BALIÐI POPULASYONUNUN BÜYÜME ÖZELLÝKLERÝ ÜZERÝNE BÝR ARAÞTIRMA

Bu çalýþmada, Solhan Deresi'nden yakalanan 190 adet siraz balýðýnýn boy ve aðýrlýk daðýlýmý, yaþ ve eþey oraný, boy-aðýrlýk iliþkisi, kondisyon özellikleri 2017-2018 yýllarý arasýnda aylýk olarak incelenmiþtir. Eþey oraný (D:E) %52.63'ü erkek ve %47.37'si diþi olmak üzere, 1:1.11 olarak bulunmuþtur. Bireyler I-VI yaþ grubu arasýnda daðýlým göstermektedirler. Total boy deðerleri 14.8-34.4cm, aðýrlýklarý ise 35.0-390.0g arasýnda olduðu saptanmýþtýr. Büyüme parametreleri, L∞=44.4, k=0.16, t0=-1.61, Ø`=2.49 olarak saptanmýþtýr. b deðerleri tüm bireyler için 2.70 olarak hesaplanmýþtýr (b<3.0). Aylýk maksimum-minimum kondisyon deðerleri her iki eþey için sýrasýyla Aðustos (1.11) ve Mayýs (0.91)) olarak hesaplanmýþtýr. Doðal ölüm oranýný M=0.36 olarak hesaplanmýþtýr.

AN INVESTIGATION ON ASPECTS OF GROWTH OF THE TIGRIS SCRAPER [CAPOETA UMBLA (HECKEL, 1843)] POPULATION LIVING IN SOLHAN CREEK OF MURAT RIVER (BÝNGÖL), TURKEY

Zeliha Erdoðan 1 , Hatice Torcu Koç2 , Fatih Özdemir3

In this study, length-weight relationships, condition, and reproduction characteristics of 190 tigris scraper, Capoeta umbla (Heckel, 1843) caught from the Solhan Creek of Murat River were investigated monthly between April 2017 and March 2018. Sex ratio (F:M) was found as 1:1.11, corresponding to 52.63% males and 47.37% females. The age groups ranged between I-VI. Total lengths and total weights of sampled fishes were determined to be ranged from 14.8-34.4 cm and 35.0-390.0 g, respectively The von Bertalanffy growth equation was fitted on the basis of mean length-at-age data resulting in parametres values of L∞=44.4cm k=0.16 to=-2.48, Ø`=2.49. b value was estimated as 2.70 for all individuals (b<3.0) The maximum-minimum condition values were found to be in August (1.11) and May (0.91) for both sexes. The natural mortality rate in population was M= 0.36.
