Abstract

Egg production, larvae and juvenile rearing potential of red porgy (Pagrus pagrus) in captivity were studied through a production season. Female brooders (1651 ±38.2 g mean body weight) were implanted with silastic capsules carrying GnRHa at a dose of 40-50 pg hormone per kg body weight. Shortly after the GnRH implants, spawning commenced on March 5 and continued up to May 30 over a 87 day period. Through out the spawning season, total fecundity of the females was 550,000 eggs / kg female weight and 80-85% of the eggs were buoyant. Green water technique was used from day 4 to 30. Larval rearing morphologic development, growth and survival rates of red porgy were determined up to day 100. The transformation stage began on day 25 and day 26 at a mean total lenght of 10.285 ± 0.79 mm and ended on day 45 at a mean total lenght of 15.33 ± 1.28 mm. Larvae reached the mean weights of 0.049 ± 0.014 and 2.3 ± 0.4 g on days 45 and 100, respectively. Survival rates were respectively 15-25%, 12-19%, 8-10% on days 30,60 and 100.

Özet

Fangri balığının (Pagrus pagrus L, 1758) yetiştiricilik koşullarındaki yumurta verimi ve larval yetiştiriciliği. Bu çalışmada fangri balığının (Pagrus pagrus) yetiştiricilik ortamında yumurta verimi, larva ve yavru balık üretim potansiyeli incelenmiştir. Anaçlara (1651±38.2 g ortama ağırlığa sahip) 40-50pg/kg miktarında implant tipinde Gn-RHa hormonu uygulanmıştır. Yumurtlama 5 Mart ve 30 Mayıs arasındaki 87 günlük bir dönemde gerçekleşmiştir. Yumurtlama periyodu süresince dişi bireylerin toplam yumurta verimi 550 000 yumurta/kg olarak tespit edilmiştir. Yumurtaların döllenme oranı %80-85 arasında saptanmıştır. Larval dönemde 4-30. günlerde yeşil su tekniği uygulanmıştır. 0-100. günler arasındaki morfolojik gelişme, büyüme ve yaşama oranları belirlenmiştir. Metamorfoz 25-26. günlerde 10,585±0,79 mm total boydaki bireylerde başlayıp 45. günde larvalar 15,33±1,28 mm total boya ulaşıncaya kadar sürmüştür. 45. günde 0.049 ± 0.014 g, 100. günde 2.3±0.4g ortalama ağırlığa ulaşılmıştır. Yaşama oranları 30. günde %15- %25,6O.günde %12-19 ve 100. günde %8-10 arasında kaydedilmiştir.
