Abstract

In this study, the effect of tank volumes on survival rates, total length and total width of gilthead seabream (Spams aurata I., 1758) larvae from hatching to the first grading were tested for periods of 0-38 days The percentage of fertilized buoyant eggs were generally higher than 90-95%. Larvae were reared intensively in 5 and 15 tons tanks under a constant photoperiod 24 h light, and fed initially on rotifers, followed by Artemia nauplii and Artemia metanauplii. A green water technique was applied using Chlore/la sp. and Isochrysis galbana at a density of $1x10^6$ cells. $ml^{-1}$ . Survival and growth rates were determined for all volumes in triplicate. Mean survival rates in 5 tons tank (12.56±0.47%) was significantly higher than that in 15 tons tank (9.83±0.76%) (P<0.05). Mean total length and width of the larvae at day 38 after were similar in both tanks (Mean length, 10.35±0.22 mm and 10.14±0.52 mm; width, 2.15±0.19 mm.and 2.11±0.24 mm, respectively).

Özet

Bu çalışmada, çipura (Sparus aurata L. 1758) larvalarının yaşama ve büyüme oranları üzerinde tank hacimlerinin etkileri, 0-38 günler için test edilmiştir. Döllenmiş yumurta oranı yüksek olup%90-95 arasındadır. Larvalar intensif koşullarda 5 ve 15 tonluk tanklarda 24 saatlik aydınlık periyotta yetiştirilmiş, ilk yem olarak rotifera daha sonra ise Artemia nauplii ve Artemia metanauplii ile besleme yapılmıştır. Yeşil su tekniği olarak Chlorella sp. ve Isochrysis ga/bana türleri $1x10^6$ hücre. $mL^{-1}$ olarak kullanılmıştır. Yaşama oranları ve gelişim oranları 5 ve 15 tonluk tanklar için değerlendirilmiştir. Beş tonluk tanklardaki ortalama yaşama oranı (% 12,56±0,47) on beş tonluk tanklardaki yasama oranından (% 9,83±0,76) önemli derecede yüksek bulunmuştur (P<0.05). Kuhjçkalamadan sonraki 38. günde, 5 ve 15 tonluk tanklarda yetiştirilen larvalarda total boy ve en değerleri benzer bulunmuştur (Boy sırasıyla 10.35±0.22 mm; 10,14±0,52 mm ve en ortalamaları sırasıyla, 2.15±0.19 mm; 2.11±0.24 mm).
