Abundance and Diversity of Winter Larval-fish Assemblages off Yumurtalık (Iskenderun Bay)

Öz

Here, abundance, diversity and composition of ichthyoplankton assemblages of İskenderun Bay was investigated in winter period together with environmental conditions. For this purpose, a total of 6 cruise works was performed between 7/12/2015 and 1/3/2016 at the six stations located at 10, 30 and 60m depth contours off Yumurtalık, İskenderun Bay. Samples were collected by using oblique tows of Bongo-60 net. During the study, eggs and larvae of 67 species were collected. Median of observed richness was 6 species per station and of abundance was 36 individual/10m². Median of Shannon-Wiener diversity index and its evenness component Pielou evenness index were 1.86 and 0.98 respectively. Bregmaceros nectabanus, Sparus aurata, Etrumeus golanii, Gobius paganellus and Sardina pilchardus were dominant species. Total abundance, richness and diversity of ichthyoplankton assemblages were significantly lower at 10m depth contour. Within winter season, temporal changes of ichthyoplankton composition were found to be significant. Amongst the environmental conditions measured, only temperature was significantly correlated with the species composition.

Yumurtalık Açıklarında (İskenderun Körfezi) Kış Dönemi Larval Balık Topluluklarının Bolluk ve Çeşitliliği

Öz

Bu çalışmada İskenderun Körfezi’nde kış mevsimi ihtiyoplankton topluluklarının bolluk, çeşitlilik ve kompozisyonu çevresel koşullarla birlikte ele alınmıştır. Bu amaçla 7/12/2015 ile 1/3/2016 tarihleri arasında 6 saha çalışması gerçekleştirilmiş; İskenderun Körfezi, Yumurtalık açıklarındaki 10, 30 ve 60m derinlik konturlarına yerleştirilmiş 6 istasyonda oblik Bongo-60 Net çekimleri yapılmıştır. Çalışma boyunca 67 türe ait yumurta ve larvalarla karşılaşılmış olup, istasyon başına medyan tür sayısı 6, bolluk ise 36 adet/10m² olarak tespit edilmiştir. Shannon-Wiener çeşitlilik indeksi ile Pielou düzenlilik indeksine ait medyan değerleri sırasıyla 1.86 ve 0.98 olarak hesaplanmıştır. Bregmaceros nectabanus, Sparus aurata, Etrumeus golanii, Gobius paganellus ve Sardina pilchardus baskın türlerdir. İhtiyoplankton topluluklarının bolluk, zenginlik ve çeşitliliği 10m derinlik konturunda istatistik açıdan önemli ölçüde düşük bulunmuştur. İhtiyoplankton kompozisyonunun kış mevsimi içindeki zamansal değişimlerinin istatistik açıdan önemli olduğu tespit edilmiştir. Ölçülen çevresel koşullardan yalnızca sıcaklık değişimlerinin tür kompozisyonu üzerinde etkili olduğu belirlenmiştir.
