Kayaboğazı Baraj Gölü (Kuzey Batı Anadolu -Türkiye)’nde yaşayan Capoeta Tinca’ nın üreme biyolojisi

This study investigates the reproduction biology of Capoeta tinca population in Kayabogazi Dam Lake in the region of Northwest Anatolia in Turkey (Kutahya). The investigation was carried out between March and December 2003. During the study, breeding and sexual maturation properties of Capoeta tinca were studied. The sexual maturity position for both sexes were II age. The spawning period was from begining of May to the end of June. The minimum fishing size was found as 214 mm in terms of fork length. According to age, the reproduction period was changing between different populations depending on ecological conditions in Turkey's areas.Bu çalışmada Kuzey Batı Anadolu Bölgesi(Türkiye)’nde yer alan Kayaboğazı Baraj Gölü’ndeki Capoeta tinca populasyonunun üreme biyolojisi incelenmiştir. Araştırma Mart ile Kasım 2003 tarihleri arasında gerçekleştirilmiştir. Çalışma süresince Capoeta tinca’nın eşeysel olgunluk ve yumurta bırakma dönemleri incelenmiştir. Eşeysel olgunluğa ulaşma yaşı, erkek ve dişi cinsiyetler için II olarak belirlenmiştir. Üreme periyodu Mayıs başlangcından Haziran sonuna kadar olan dönemi kapsamaktadır. En küçük av büyüklüğünün (çatal boy olarak) 214 mm olduğu tespit edilmiştir. Türkiye’nin farklı bölgelerinde değişen ekolojik şartlar nedeniyle, üreme periyodunun yaşa bağlı olarak populasyonlar arasında farklılıklar gösterdiği anlaşılmıştır

Cases of external myiasis caused by diptera (Sarcophaga sp.) on three cyprinid species

WOS: 000263995500003Sarcophaga sp. caused external myiases on three cyprinid species caught from Ataturk Dam Lake, Turkey) in July 2006. A total of 130 live dipteran larvae were collected from the body surfaces of Cyprinus carpio L., 1758, Barbus grypus Heckel, 1843, and Capoeta trutta Heckel, 1843. There was 100% infestation of all three species of fish, with a mean intensity of 13.6 for C. carpio, 5.6 for B. grypus, and 4.3 for C. trutta. The myiases were probably accidental infections on stressed and immobilized fishes

Investigation of some population parameters of the tench (Tinca tinca L.,1758) inhabiting Beyşehir Lake (Konya, Tukey)

This study was carried out between April, 2004 and March, 2005 in Beyşehir Lake in the Central Anatolian Region of Turkey. The present study of 210 Tinca tinca from Beyşehir Lake shows that 52.38 % are female and 47.62 % male ranging between I+-VIII age groups. The sex ratio was 1.10 female:1 male in the studied samples. Specimens ranged from 14.9 to 38.5 cm in fork length, and 48.5 to 967.10 g in weight. At the same time, fork length and weight distributions of Tinca tinca were also given in this study. Age-length and age-weight relations were calculated by the von Bertalanffy growth formula. The following equations were found for males and females, respectively. Lt=41.36[1- e1-0.152(t+3.1396)], Lt=44.23[1- e1-0.1176(t+3.6745)], Wt= 1202.16 (1- e- 0.52(t+3.1396 )3.0993, Wt=1458.30 (1- e-0.1176 (t+3.6745) )3.0718.This study was carried out between April, 2004 and March, 2005 in Beyşehir Lake in the Central Anatolian Region of Turkey.

Bu çalışma, Ocak-1996, Aralık-1997 tarihleri arasında Kayaboğazı Baraj Gölü'nde yapılmıştır. Bu periyot süresince 424 birey incelenmiştir, incelenen örneklerde dişi ve erkek bireylerin I-V1I yaş arasında dağılım gösterdiği tespit edilmiştir. Çatal boy ve ağırlık dişi ve erkeklerde sırasıyla 102-277 mm, 15-377,02 g ve 125-274 mm, 27-369,02 g'dır. Dişi ve erkek bireylerin boyları ve ağırlıkları arasında istatistiksel açıdan bir fark bulunmadığı saptanmıştır. Eşey oranı (erkek:dişi) 0,947:1 olarak hesaplanmıştır. Gonadosomatik indeks değerleri l ,40-10,19 arasında değişim göstermiştir. Eşeysel olgunluğa ulaşma yaşı erkek ve dişilerde sırasıyla 111 ve IV olarak tespit edilmiştir. Üreme periyodunun Haziran'ın başlangıcından Temmuz ayının sonuna kadar gerçekleştiği belirlenmiştir. Ortalama yumurta sayısı her bir birey için 42724 ± 5658,93 olarak tahmin edilmiştir. Ayrıca, fekondite ile vücut uzunluğu (L) ve vücut ağırlığı (W) arasındaki regresyon eşitlikleri sırasıyla, Log F = -2,18301 + 2,923 log L (r = 0,96) ve Log F = 2,889918 +'0,792 log W (r = 0.97) olarak bulunmuştur.This study was carried out between January 1996 and December 1997 in Kayaboğazı Dam Lake.

Türkiye deniz balığı türlerinde Gnathia sp. (Gnathiidae) infestasyonu

Alaş, Ali ( Aksaray, Yazar )Bu çalışma Haziran-Ağustos 2006 periyodunda yapılmıştır. Marmara Denizi, Karadeniz ve Ege Denizi’nden yakalanan 10 farklı balık türünden toplam 150 balık incelenmiştir. Bu amaçla her bir balığın vücut yüzeyi, yüzgeçleri, solungaçları ve ağız boşluğu disseksiyon mikroskobu ile incelenmiştir. Bundan sonra ektoparazit örnekleri disseksiyon mikroskobu altında incelenmiş olup, toplanan balıkların teşhis edileceği zamana kadar %70’lik etanolde muhafaza edilmiştir. Gnathia sp. larvalarına enfekte balıkların solungaç flamentleri ve ağız boşluklarında rastlanmıştır. Bu çalışmayla Türkiye’de Serranus cabrilla; Mullus surmuletus; Mugil cephalus; Trachurus mediterraneus; Sarpa salpa; Sciaena umbra balık türlerinden Gnathia sp. ilk defa rapor edilmektedir.This study was carried out between June and August 2006. Totally 150 samples out of ten different fish species caught from the Marmara Sea, the Black Sea and the Aegean Sea were examined. For this purpose, body surface, fins, gills and mouth cavity of each fish were examined with the aid of a dissecting microscope. After that, ectoparasite samples were preserved in 70% ethanol to be observed under the dissecting microscope for identification. Gnathia sp. was found out in the mouth cavity and gill flaments of these infected fishes. This is the first study reporting Gnathia sp. from Serranus cabrilla; Mullus surmuletus; Mugil cephalus; Trachurus mediterraneus; Sarpa salpa; Sciaena umbra
