Abstract

The growth parameters of gilthead seabream (Sparus aurata) fry supplied from three different hatcheries stocked in nine HDPE offshore cages (30 m diameter and 22 m depth) were investigated for 450 days. It was determined that the fish obtained from Firm A on the 450th day gained more weight by consuming less feed. Fishes belonging to Firm A consumed an average of 1.8 kg of feed for one kg body weight gain, while fishes belonging to Firm B consumed an average of 2.29 kg and fishes of Firm C consumed an average of 2.18 kg. However, feed conversion rates were not significant between firms. Also, the highest survival rate was determined in fish from Firm B with 96.11%. As a result, the success of fish culture should be guaranteed by the supply of high standard juvenile fish. Otherwise, production costs and fish quality will be adversely affected.

Özet

Dokuz HDPE açık deniz kafesinde (30 m çapında ve 22 m derinliğinde) stoklanan üç farklı kuluçkahaneden temin edilen çipura (Sparus aurata) yavrularının büyüme parametreleri 450 gün boyunca incelenmiştir. Firma A'dan elde edilen balığın 450. günde daha az yem tüketerek daha fazla kilo aldığı belirlenmiştir. Firma A'ya ait balıklar bir kg vücut ağırlığı artışı için ortalama 1.8 kg yem tüketirken, Firma B'ye ait balıklar ortalama 2.29 kg ve Firma C'ye ait balıklar ortalama 2.18 kg tüketmiştir. Ancak, yemden yararlanma oranları arasında önemli bir fark tespit edilmemiştir. Ayrıca, en yüksek hayatta kalma oranı % 96.11 ile Firma B'den elde edilen balıklarda tespit edilmiştir. Sonuç olarak, balık kültürünün başarısı, yüksek standartta yavru balıkların sağlanmasıyla garanti altına alınmalıdır. Aksi takdirde üretim maliyetleri ve balık kalitesinin olumsuz etkilenmesi kaçınılmazdır.
