Özet
Çalışmada, doğadan yakalanan yavru pisi balıklarının (Platichthys flesus luscus L. 1758) tanklarda farklı beslenme yöntemlerindeki büyüme parametrelerinin belirlenmesi amaçlanmıştır. Çalışma Nisan-Temmuz 2011 tarihleri arasında yapılmış olup, balıklar Sinop ili Sarıkum Lagünü'nün deniz ile birleştiği alandan ığrıp ve kepçelerle toplanmıştır. Ortalama ağırlığı 0,930,03 (0,73-1,21) g olan 750 adet yavru pisi balığı, 3 tekerrürlü 5 grup olarak tanklarda stoklanmıştır. Gruplar beslenme protokollerine göre düzenlenmiştir [G1:90 gün Chironomid larvası (CL), G2:60 gün CL30 gün CLGranül yem (GY), G3:30 gün CL60 gün CLGY, G4:90 gün CLGY, G5:90 gün GY]. Deneme sonunda beslenme protokollerine göre balık ağırlıkları sırasıyla 10,830,51, 9,890,22, 6,330,21, 5,130,11 ve 3,810,09 olduğu bulunmuştur. Balıkların beslenme tercihlerinin ağırlık artışı, spesifik büyüme oranı, yem değerlendirme oranı ve yaşama oranı üzerinde etkili olduğu tespit edilmiştir. Yavru pisi balıkları, doğada olduğu gibi tanklarda çoğunlukla dipte hareket eden doğal yemleri daha fazla oranda tercih etmiştir. Balıkların adaptasyonunda başlangıç yemi olarak canlı yemin uzun süreli tercih edilmesinin büyüme parametreleri ve yaşama oranı bakımından önemli olduğu belirlenmiştir.
The aim of this study was to determine the growth parameters of European Flounder fry (Platichthys flesus luscus L. 1758) caught from the nature in different feeding methods in aquaculture conditions. The study was conducted between April and July 2011, and the fish were collected at the connection point of Sarıkum Lagoon with the Black Sea in Sinop Province using seines and large scoops. A total of 750 European Flounder with the average weight of 0.93±0.01 (0.71-1.21) g were stocked in 5 groups with 3 repetitions. The groups were organized according to the feeding protocols [G1:90 days Chironomid larvae (CL), G2:60 days CL30 days CL granular feed (GY), G3:30 days CL60 days CL GY, G4:90 days CLGY, G5:90 days GY]. At the end of the study, the weights of the fish were determined as 10.83±0.51, 9.89±0.22, 6.33±0.21, 5.13±0.11, 3.81±0.09, respectively. It was found that feeding preferences of the fish had significant effects on weight gain, specific growth rate, feed conversion ratio and survival rate. European Flounder fry, as in their natural habitat, mostly preferred natural feed moving in the deep in the production site. It was determined that using live feed as the starter feed for the adaptation of European Flounder fry had a significant effect on growth parameters and survival rates.
