Abstract

Assessing the possibility for cultivation of the smooth scallops (Flexopecten glaber) along the Bulgarian Black Sea coast requires a form one side very good knowledge of the biology of species, and from the other side internal organs and reproductive tissues, also the changes occurring during reproductive processes. Thus, the study aimed to investigate and evaluate the histological structure of the internal organs of the Flexopecten glaber caught in the Black Sea. Three samples were collected in June 2022 from commercial fishing in Black Sea waters near Cape Shabla. The shell length and weight of each mussel were measured and recorded. The study was carried out by making histological preparations of gonads and internal organs in adult smooth scallops. Histologically organs of smooth scallop showed that the tissues were in normal cytological condition. The microscopic analysis showed that the heart is located dorsal to adductor muscle. The kidneys are situated in the anterior margin together with gonads which cover the last one. Ventral to the gonad are attached pairs of gills. The histological structure of the gonads and internal organs of scallops was identified and described. The results of the current investigation expand the field of knowledge on the anatomy and histology of smooth scallops.

Karadeniz suları Shabla Burnu yakınlarından yakalanan deniz tarağının (Flexopecten glaber) iç organlarının histolojik yapısı

Abstract

Bulgaristan'ın Karadeniz kıyısı boyunca yumuşak deniz tarağı (Flexopecten glaber) yetiştirme olasılığının değerlendirilmesi, bir yandan türlerin biyolojisi, diğer yandan iç organlar ve üreme dokuları ile üreme süreci boyunca meydana gelen değişiklikler hakkında çok iyi bilgi gerektirir. Bu nedenle çalışmanın amacı, Karadeniz'de yakalanan Flexopecten glaber’ in iç organlarının histolojik yapısının incelenmesi ve değerlendirilmesidir. Haziran 2022'de Karadeniz sularında Shabla Burnu yakınlarındaki ticari balıkçılık yolu ile üç adet örnek toplandı. Her midyenin kabuk uzunluğu ve ağırlığı ölçüldü ve kaydedildi. Çalışma, yetişkin deniz taraklarının gonad ve iç organlarının histolojik hazırlıkları yapılarak gerçekleştirildi. Doku yapılarının gözden geçirilmesi için hematoksilen ve eozin (H&E) boyama prosedürü kullanıldı. Deniz tarakların gonad ve iç organlarının histolojik yapısı belirlendi ve tanımlandı. Mevcut araştırmanın sonuçları, deniz taraklarının anatomisi ve histolojisi hakkında bilgi sunmaktadır.
