In this study, a total of 82 (49♀♀, 33♂♂) Cyprinion kais samples from the same location in the river of Tigris were collected and ages of scales taken from front and upper section of lin lateral of dorsal fins of fishes were determined and photographed by an Olympus digital camera with Canon SX7 model binocular under the same conditions and then six landmarks were taken by using tpsDig ver. 2.32 software. Afterwards, procrustes analysis was conducted. After separating shapes and sizes, ANOVA, PCA, CVA/MANOVA and DFA analyses were performed. According to the results of the analyses, there was a significant difference between the samples in terms of gender and size (Size ANOVA: F= 50.6, p<.0001); at the same time the difference between samples in terms of shape was at the level of (Shape ANOVA: F= 3.92, p =0.0002); there was a significant difference between samples at different ages in terms of size (Size ANOVA: F= 44.08, p<.0001), however, no difference was found in terms of the shape of the samples; there was a significant difference between size (Size ANOVA: F= 17.87, p<.0001) of the samples but no difference was found between shape of them depending on the season. For gender, age and seasons, the first two components explain 61.4%, 63.6% and 63.4% of total variance, respectively. As a result, there was a difference between sizes of the C. kais species depending on gender, age of the fishes and the season; however, although there was a difference between shapes of the samples depending on gender variable, no difference was found depending on age of the fish and the season.
In this study, a totally 103 (53♀♀, 50♂♂) C. trutta and 82 (67♀♀, 15♂♂) C. umbla samples from the Tigris River between Ilısı Dam and Cizre town were collected and ages of scales taken from front and upper section of line lateral of dorsal fins of fishes were determined and one scale from each fish sample photographed by an Olympus digital camera with Canon SX7 model binocular under the same conditions with 40X magnification and then six landmarks were taken by tpsDig. After GPA (General Procrustes Analysis) performed, ANOVA (Analysis of Variance), PCA (Principal Component Analysis), CVA (Canonical Variance Anlysis) and DFA (Discriminant Function Analysis) analysis were conducted by MorphoJ and PAST. In CV (Canonical Variance) Analysis, the permutation p-value of the mahalanobis and procrustes distance between the two species (p<.0001) shows that the difference is quite significant. As a result of the reclassification done by the analysis, we see that 79% of C. umbla and 77% of C. trutta are classified correctly.
Bu çalışmada bağırsak parazitlerinin süs balıkları için ciddi sağlık sorunu oluşturabildiğinin gösterilmesi amaçlanmıştır. Üretimi gerçekleştirilen Sarıprenses balıklarının (Labidochromis caeruleus) bir kısmında aşırı zayıflama, dengesiz yüzme, asites ve deride matlaşma gibi değişikliklerin ardından öldükleri görüldü. Bu şekilde ölen balıkların ölüm sebebinin saptanması maksadıyla ölen balıklarda nekropsi işlemi gerçekleştirildi. Nekropsi sonucunda iç organlar diseke edilip, histopatolojik olarak incelendi. HxE ile boyanan preparatlarda yapılan histopatolojik incelemede, bağırsakta yoğun miktarda parazit varlığı tespit edildi. Aşırı parazit enfastasyonunun bağırsakta ciddi fonksiyon kaybına yol açabilecek derecede önemli patolojik hasarlar meydana getirdiği görülmüştür. Ticari önem taşıyan bu süs balıklarının ciddi parazit enfestasyonuna maruz kaldıkları ve bu balıkların ölüm nedenlerinin yoğun parazit varlığından kaynaklanabileceği kanısına varılmıştır. Bu tür balıklarda yapılan çalışmaların az olması ve süs balıklarındaki iç parazit araştırmalarının yetersiz olması çalışmamızı önemli kılmaktadır.
In this study, the relationships between otolith length (OL) -total length (TL), otolith width (OW) -total length (TL), otolith length (OL) -otolith width (OW) were examined for Shiraz barb [Capoeta umbla (Heckel, 1843)] in the İkizce Stream. The fish samples were collected by nets in February -March 2014 from the İkizce stream in Şırnak. A total of 76 specimens (15 female and 61 male) provided otolith samples for analysis. Relationship between total length and otolith length were determined as y=0,0565x +1,1008 (r=0,6602), relationship between total length and otolith width were determined as y=0,0651x +0,4226 (r=0,6504) and relationship between otolith length and otolith width were determined as y=0,7614x +0,0602 (r=0,8268). There was not significant differences between right and left otolith biometry (ANOVA p>0.05).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
