Karyotype of the Black Sea Turbot, Scophthalmus maeoticus Pallas 1814 Pisces: Pleuronectiformes

Abstract

In this study, using conventional staining method, chromosome structures and numbers of Black Sea turbot Scophthalmus maeoticus Pallas 1814 , a species of flatfish living in the Black Sea, have been examined. The specimens of the fish were obtained through fishing in regions between the coasts of West and Middle Black Sea of Turkey. It was determined that S. maeoticus had a diploid number chromosomes of 2n= 44 and a fundamental number of NF= 48. The karyotpe of turbot contained 2 pairs of metacentric, 7 pairs of subtelocentric and 13 pairs of acrocentric chromosomes

Karadeniz Kalkan Balığının, Scophthalmus maeoticus Pallas 1814 Pisces: Pleuronectiformes Karyotipi

Abstract

Bu çalışmada geleneksel boyama metou kullanılarak Karadeniz’de yaşayan yassı balıkların bir türü olan Karadeniz Kalkanı Scophthalmus maeoticus Pallas 1814 ’un kromozom yapıları ve sayıları incelenmiştir. Balık örnekleri Türkiye’nin Batı ve Orta Karadeniz kıyıları arasında kalan bölgeden avcılık yoluyla elde edilmiştir. S. maeoticus’un 2n=44 diploid kromozoma sahip olduğu ve kromozom kol sayısının da NF=48 olduğu tespit edilmiştir. Kalkan balığının karyotipinin 2 çift metasentrik, 7 çift subtelosentrik ve 13 çift akrosentrik kromozom içerdiği belirlenmiştir
