Relationships Between Opercle Dimensions and Total Length of European Perch (Perca fluviatilis L., 1758) Inhabiting Lake Ladik (Samsun, Turkey)

There are so many researches about the effects of exercise on pulmonary Junctions. In some studies it were found that pulmonary function improved with exercise and in the others did not. It was generally accepted that there were improvement in pulmonary functions with swimming and diving. In this article the effects of exercise on pulmonary functions are reviewed.

The Relationships Between Otolith Dimensions-Total Length of Chub (Squalius cephalus, L.1758) Sampled from Some Inland Waters of the Middle Black Sea Region

Bu calismada Karadeniz Bolgesi’ndeki bazi icsularda yasayan tatlisu kefalinin ( Squalius cephalus, L.1758) total boy ile otolit ozellikleri arasindaki iliskiler arastirilmistir. Tatlisu kefali ornekleri 4 farkli lokaliteden (Abdal Cayi, Akcay, Terme Cayi ve Yedikir Baraj Golu) yakalanmistir. Otolit olcumleri ile total boy arasindaki iliskilerin hesaplanmasi icin power model kullanilmistir. Istatistiksel analizler Paired t-test, Independent t test, ANOVA ile test edilmistir. Abdal, Akcay, Terme Cayi ve Yedikir Baraj Golu’nden elde edilen bireylerin ortalama total boylari sirasi ile 11,49±0,79 cm, 10,31±0,52 cm, 10,33±0,29 cm ve 11,11±0,33 cm arasinda degismektedir. Lokalitelere gore tum veriler birlikte degerlendirildiginde asteriskus ve lapillus otolitlerinin otolit enleri ( OB ) ve otolit boylari ( OL ) arasinda bir farklilik bulunmamaktadir. Fakat dort lokalite birlikte degerlendirildiginde lapillus otolit agirliklari arasinda fark mevcuttur. Lokalitelere gore asteriskus otolit agirliklari bakimindan bir farklilik mevcut degildir. TL ve OB , OL ile OW arasindaki iliskiler power regresyon modeli kullanilarak belirlenmistir. Terme (r 2 =0,936) ve Yedikir icin OW (r 2 =0,912), Akcay ve Abdal Caylari icin OL ( r 2 =0,973) degerlerinin TB ile en kuvvetli iliskileri gosterdigi belirlenmistir.

Length-weight and length-length relationships of chub (Squalius cephalus, L., 1758) inhabiting a few inland waters of the Middle Black Sea Region

Bu calismada orta Karadeniz Bolgesi’ndeki bazi icsularda yasayan tatlisu kefalinin ( Squalius cephalus, L.1758) boy-agirlik ve boy-boy iliskileri incelenmistir. Toplamda 218 (Abdal (N=44), Akcay (N=57), Terme (N= 55), Yedikir (N=62)) ornek farkli lokalitelerden orneklenmistir. Yakalanan tum orneklerin total, catal ve standart boylari (0.1 cm) olculmustur. Her bir ornegin agirligi (W) kaydedilmistir (0.01 g). Analiz sonuclarina gore cinsiyetler arasinda boy ve agirlik bakimindan istatistiksel olarak onemli bir farklilik yoktur (P ˃ 0.05). Bu sebeple tum populasyon (disi+erkek) analizlerde birlikte degerlendirilmistir. Abdal Cayi, Akcay Cayi, Terme Cayi ve Yedikir Baraj Golu’nden orneklenen tatlisu kefalinin ortalama total boylari sirasiyla 11.49±0.792, 10.31±0.518, 10.33±0.289 ve 11.11±0.327 cm arasinda degismektedir. Boy-agirlik iliskileri tum lokaliteler icin onemli bulunmustur (P 0.990). Boy-agirlik iliskisinin “b” degeri istatistiksel anlamda 3’ten faklidir ve tum lokaliteler icin buyume tipi pozitif allometriktir. Boy-agirlik iliskilerinin denklemleri sirasi ile Abdal, Akcay, Terme ve Yedikir icin W=0.007TL 3.224 , W=0.006TL 3.285 , W=0.005TL 3.298 , W=0.007TL 3.210 olarak hesaplanmistir. Boy-boy iliskilerinin regresyon katsayilari 0.916 ile 0.999 arasinda degisim gostermektedir ve istatistiksel anlamda onemlidir (P<0.001).

BIOLOGICAL CHARACTERISTICS OF EUROPEAN PERCH (Perca fluviatilis L., 1758) INHABITING LAKE LADIK (SAMSUN, TURKEY)

Abstract The aim of this study was to determine the growth features of European perch (Perca fluviatilis L., 1758) inhabiting Lake Ladik. A total of 858 individuals were caught. The total length and weight ranged from 8.2 to 27.5 cm and from 7.16 to 365.20 g, respectively. The age of the females ranged between 1 and 7 years and the age of the males ranged from 1 to 5 years. The female to male ratio was 1:0.19. The von Bertalanffy growth equation parameters were determined as L∞=41.27 cm, W∞=1251.40 g, K=0.10 (year−1), t0 (year)=−1.98 for all samples. Length-weight relationship was calculated as W=0.0047TL3.358 for all specimens. Length-length relationships (total length-standard length, total length-fork length, standard length-fork length) were highly significant (r2>0.98). The mean condition factor value was obtained as 1.28 for all fish. Condition factor showed statistically significant increase according to length classes.
