Composition of eggs and larvae of fish and macrogelatinious zooplankton in Sinop Region (The Central Black Sea) during 2002

Abstract

This study was carried out in order to determine abundance and distribution of macrogelatinous organisms (Aurelia aurita, Pleurobranchia pileus, Mnemiopsis leidyi ve Beroe ovata) with respect to fish egg and larvae in Sinop region in 2002. Three stations were selected this region and plankton tows were made both verticallly and horizontally. In study the ctenophores M. leidyi between January and September, and B.ovata between August and December period were appeared. The cnidarian Aurelia aurita and the ctenophore Pleurobranchia pileus showed a wider distribution in 2002. A total of 857 eggs and 150 larvae were collected from ichthyoplankton samples and 8 species belonging to 8 families were identified. Most of ichthyoplankton
included Sprattus sprattus phalericus 77.7%, Engraulis encrasicolus ponticus10% and Mullus barbatus 10% of total eggs, S. s. phalericus 51%, Blennidae family 15% and E. e. ponticus 13% of total larvae. The abundance and species number of ichthyoplankton were lower in the present study than found in 1999-2000. Overall in the warm period, the abundance of both macrogelatinous organisms and fish egg and larvae were found to increases. No correlations were found between macrogelatinous organisms and fish egg and larvae in this relatively short sampling (during a year) period (p>0.05).

Bu araştırmada 2002 yılında Orta Karadeniz’in Sinop Bölgesi’ndeki makrojelimsi organizma (Aurelia aurita, Pleurobranchia pileus, Mnemiopsis leidyi ve Beroe ovata) türleri ile balık yumurta ve larvalarının bolluğu ve dağılımının tespit edilmesi amaçlanmıştır. Bunun için bölgede seçilen 3 istasyonda, dikey ve yatay olarak plankton çekimleri yapılmıştır. Araştırmada ktenoforlardan Mnemiopsis leidyi Ocak-Eylül, Beroe ovata Ağustos-Aralık periyotlarında görülebilmiştir. Aurelia aurita ve Pleurobranchia pileus türleri ise 2002 yılında geniş dağılım göstermişlerdir. İhtiyoplankton örneklerinden toplam 857 adet yumurta ve 150 adet larva toplanmış olup 8 familyaya ait 8 tür tayin edilmiştir. Toplam yumurtanın %77.7’sini Sprattus sprattus phalericus, %10’unu Engraulis encrasicolus ponticus ve %10’unu da Mullus barbatus türüne ait yumurtalar oluşturmuştur. Toplam larvanın %51’ini S. s. phalericus, %15’ini Blennidae familyası ve %13’ünü de E. e. ponticus türleri oluşturmuştur. İhtiyoplankton tür sayısı ve bolluğu 1999-2000 yılından daha düşük bulunmuştur. Sıcaklık değerlerinin yükseldiği dönemlerde jelimsi organizma ile balık yumurta ve larva miktarlarının arttığı belirlenmiştir. Kısa süreli örneklemelerde (bir yıl boyunca) jelimsi organizmalarla balık yumurta ve larvaları arasındaki net bir ilişki bulunamamıştır (p>0.05)
