Kolektörler altı grup olarak hazırlandı ve uzun halat sistemiüzerine yerleştirildi. Sıcaklık, tuzluluk, klorofil-a ve toplam partikül maddemiktarı gibi çevresel parametreler çalışma periyodu boyunca izlendi. P. radiata spatı ilk olarak Ağustosayında torba kolektörlerde 11,66±2,08 birey/0,91 m2, kabuk kolektörlerdeise 2,33±1,52 birey/0,91 m2 olarak tespit edildi. Aynı ayda enyüksek sıcaklık ve tuzluluk değerleri sırasıyla 27 °C ve ‰ 36,5 olarak kayıtedildi. Çalışma boyunca, torba kolektörlerde en iyi spat toplama performansınıGrup 2 (G2-25 Haziran’da yerleştirildi) gösterirken, kabuk kolektörde G4 (29Ağustos’ta yerleştirildi) daha başarılı olmuştur. Toplamda 172±34,39 spattoplandı. 119±22,60 (69.18%) spat torba kolektörlerle toplanırken, 53±11.78(30.82%) spat kabuk kolektörlerle toplandı. Ortlama 7,26 birey/m2Pinctada spatı torba kolektörlerde, 3,23 birey/m2 kabuk kolektördebelirlenmiştir. Kolektör grupları arasında toplam spat bulunma farkının önemliderecede anlamlı çıktığı görülmüştür (p<0,05). Torba kolektörler üzerindebulunan Pinctada spatlarının boy aralığı 4,47-33,9 mm arasında değişirken,kabuk kolektörler üzerinde bulunan spatların boy aralığı 4,66-18 mm arasındadeğişim gösterdi. Fouling organizmalar (Balanus, Poliket, Bryozoa) ve predatörtürler de (yengeç ve gastropod) kolektör gruplarında bulundu. Çalışma sonucundatorba kolektörlerin kabuk kolektörlere oranla daha verimli olduğubelirlenmiştir. CR - Acarli, S., Lök, A., & Acarli, D. (2011).
