The Maximum Length Record of the Blackspot Seabream (Pagellus bogaraveo Brünnich, 1768) for the Entire Aegean Sea and Turkish Territorial Waters

The maximum length, weight, and age information of organisms in an ecosystem, moreover, the first records of migrated exotic species are essential in terms of the basis for the studies on population dynamics, stock assessment, and biological activities. Therefore, the recording of such data may be necessary for scientific databases and new related studies. The Blackspot seabream (Red seabream - Pagellus bogaraveo), which belongs to the Sparidae family, is an important seafood which is marketed fresh and frozen around the Mediterranean and the Aegean seas. Nowadays, this species has high prices depending on market demands in domestic markets as a result of overfishing and is also cultured in northern Spain. It is classified as “Near Threatened Species” in the red list due to its decreasing population trend by the IUCN. A single specimen of the Blackspot seabream with 30.7 cm in total length and 390.00 g in total weight, which was angled in the Saros Bay with a handline by a fisherman on February 08, 2019, was obtained from a fishmonger in Çanakkale. Even though there are bigger individuals in the North-east Atlantic probably depending on polar and/or deep-sea gigantism, the mentioned measurement is the proven maximum total length of this species for the Aegean Sea up to the time.

Tüm Ege Denizi ve Türk Karasuları için Mandagöz Mercan’ın (Pagellus bogaraveo Brünnich, 1768) Maksimum Total Boy Kaydı

Bir ekosistemdeki canlılara ait maksimum boy, ağırlık ve yaşın bilinmesi, ayrıca göç ile gelen yabancı türlerin ilk kayıtlarının oluşturulması; popülasyon dinamiği, stok tahmini ve biyolojik aktiviteler üzerine yapılan çalışmaların temelini oluşturması açısından önemlidir. Bu nedenle, bu tür verilerin kaydedilmesi, bilimsel veri tabanı oluşturulabilmesi ve tür ile ilgili yeni çalışmalar için gerekli olabilir. Sparidae familyasının bir türü olan Mandagöz mercan (Pagellus bogaraveo), Akdeniz ve Ege çevresinde taze ve dondurulmuş olarak pazarlanan önemli bir deniz ürünüdür. Günümüzde bu tür, aşırı avlanma sonucu iç piyasalardaki taleplere bağlı olarak yüksek fiyatlara sahiptir ve kuzey İspanya'da kültürü de yapılmaktadır. Azalan populasyon eğilimi nedeniyle, IUCN tarafından kırmızı listede, Yakın Tehdit Altındaki Türler (NT) listesine dahil edilmiştir. 08 Şubat 2019 tarihinde, bir balıkçı tarafından Saroz Körfezi’nde olta ile yakalanan 30,7 cm total boya ve 390,00 gr ağırlığa sahip bir adet Mandagöz mercan balığı, Çanakkale’deki bir balık satıcısından temin edilmiştir. Muhtemelen polar ve/veya derin deniz gigantizmine bağlı olarak Kuzey Doğu Atlantik’te daha büyük bireyler olsa da, söz konusu ölçüm, bu türün Ege Denizi için kanıtlanmış şu ana kadarki en büyük total boy değeridir.
