Özet
Bu çalışmada Nisan 2018- Nisan 2019 arasında balık çiftliklerindeki üretim
faaliyetinden kaynaklanan besleyici maddelerin, suyu süzerek beslenen
midyelerin yetiştiriciliğinde kullanılması amacıyla Balıklıova/İzmir’de bulunan
bir balık çiftliğine midye entegre edilmiştir. Balık çiftliğinin etki alanı
belirlenmeye çalışılmış ve etki alanı, çiftlik merkezi ve çiftliğin etki alanı dışında
kalacak şekilde belirlenmiş 3 istasyonda midyelerin büyütme, yaşama ve üreme
performansları incelenmiştir.
Çevresel parametrelerin belirlenebilmesi için bir yıl boyunca aylık olarak
çalışma alanından sıcaklık, tuzluluk, klorofil-a ve seston ölçümleri yapılmıştır.
Aylık olarak alınan midye örnekleri Ege Üniversitesi Su Ürünleri Fakültesi Urla
Yerleşkesi’ndeki laboratuara getirilerek biyometrik ölçümleri yapılmış, yaş et
verimi ile kondisyon indeksleri hesaplanmış ve gonad gelişim safhaları
incelenmiştir.
Balık çiftliğine entegre edilen midyelerden etki alanındaki istasyonda
büyümenin, istatistiksel olarak diğer iki istasyondan farklı olduğu tespit edilmiş
(P<0,05) ve çalışma başlangıcında ortalama boyları 10±0,64mm olan midyeler bu
istasyonda 61,36±4,2mm son boya ulaşmıştır. Çalışma alanındaki midyelerin yaz
aylarında üreme faaliyeti göstermedikleri dinlenme aşamasında oldukları; suların
soğumaya başladığı Ekim, Kasım aylarında cinsel olarak aktif hale geldiği ve
Aralık, Ocak, Şubat, Mart aylarını kapsayan kış döneminde döl bıraktıkları tespit
edilmiştir.
In this study, mussels were integrated into a fish farm located in Balıklıova/İzmir in order to use the nutrients arising from the production activities in fish farms between April 2018 and April 2019 in the cultivation of mussels fed by filtering the water. The impact area of the fish farm was tried to be determined and the rearing, survival and reproduction performances of the mussels were examined in 3 stations, which were the farm center, the impact area and the unimpact area. In order to determine the environmental parameters, temperature, salinity, chlorophyll-a and particulate matter were measured monthly. Monthly taken mussel samples were brought to the laboratory at Ege University Faculty of Fisheries Urla Campus, biometric measurements were made, meat yield and condition indices were calculated and gonad development stages were examined. It was determined that the growth in the impact area station was statistically significant than the other two stations (P<0,05) and the mussels with an average initial length of 10 ± 0.64mm reached a final size of 61.36 ± 4.2mm at this station. The mussels in the study area are in the resting phase in the summer months; it was determined that as the water temperature decreases in October and November they became sexually active and spawning occurs during the winter period covering December, January, February and March.
