Tilapia were acclimated to the water source which had 8 precipitation (ppt) of salinity in experimental unit before experiment started and then, they transfered five different saltwater (SW) treatments: SW (8 ppt), 50% (12 100% (16 150% (20 200% (24 ppt).The objectives this study were; investigate effects salinities on specific growth rate (SGR), weight gain (WG), food intake (FI) survival tilapia long term trial (30 days) find out how affects muscle content, hematosomatic index (HSI), blood...
Knowledge of population structure and genetic diversity within between wild farmed populations gilthead sea bream (Sparus aurata) European seabass (Dicentrarchus labrax) is important to achieve sustainable aquaculture production these species assess the risk impacts fish escaped from farms. Previous studies on have been based a limited number markers samples. In this study, features were assessed using samples 24 seabream 25 distributed throughout Mediterranean Sea, 3 Atlantic populations....
The meagre Argyrosomus regius is a large Sciaenid fish known to reproduce in the eastern Atlantic and Mediterranean Sea just five distinct restricted geographic areas: along Mauritanian coast at estuary openings (Gironde, Tagus, Guadalquivir Nile). biological traits of A. (high dispersal capabilities, high fecundity, long larval phase, overlapping generations, reproduction until 40 years age) are, principle, favourable gene flow, which should lead genetic homogeneity over scales....
Ozone (O3) dissolved in seawater (ODS) was evaluated, as an egg disinfectant, on the spawn of captive gilthead sea bream, Sparus aurata, brood stock. Four contact times (CT) were tested (0.6, 1.2, 2.4 and 4.8 mg min L−1) where CT calculated by multiplying O3 concentration (0.3 different exposure periods (2, 4, 8, 16 min). There also a disinfected treatment that contained no or derived compounds (CT 0) untreated control. All ODS treatments reduced surface bacterial counts to zero, which...
A 180-day feeding trial was carried out in net cages to examine replacement of fishmeal with soybean meal supported by meat/bone and blood practical diets for sea bass (Dicentrarchus labrax L. 1758). Triplicate groups fish (initial body weight 110 g) were fed one four isonitrogeneus (crude protein 46%) isolipidic (10%) diets. commercial diet containing 64% as the sole animal served control. The other three contained 0, 20%, or 35% reduced replaced different levels meal, meal. final 20%...
Age and growth of adult gilthead seabream, Sparus aurata were determined from 332 specimens (total N = 476), collected purse-seiners, in the south-eastern Aegean Sea November 2006 to January 2007. The fork length body wet weight ranged 26.5 51.5 cm (mean: 36.6 ± 0.18) 375 2600 g 1009.2 14.16), respectively. groups varied between 2 7.

Insulin-like growth factor II (IGF-II) is a peptide hormone which plays crucial role in the and metabolic regulations of vertebrates.In this study, we identified single nucleotide polymorphisms on IGF-II gene European sea bass (Dicentrarchus labrax) revealed potential association between genotypes traits 150 bass.The were determined using DNA sequencing PCR-RFLP methods two different regions gene.An AT indel SNPs as g.5127711C>G g.5127731G>T intron 2 region, one SNP g.5129188C>T 3 region...
Fats have a function in transmitting the necessary fatty acids to fish as well being an energy source nutrition. In particular, high-chain unsaturated are needed for feeding saltwater fish. this study, acid composition of oils obtained from some whole-body and by-products used fish-feed industry Turkey was determined compared with each other. Accordingly, SFA (Saturated acids) ratios were range 15.57-33.38% 16.3-31.89% by-products; MUFA (Monounsaturated 24-38.69% 25.81-47.57% PUFA...
The growth of fish in intensive farming is carried out completely by the feeds supplied from externally. Different ingredients are used feed production. nutritional content these checked when purchased or brought to factory. These then stored until Storage duration and storage temperatures directly affect freshness criteria ingredient materials. Especially high-energy with high levels fat poor conditions, fats oxidized, therefore peroxide number increases becomes bitter. Oxidation not only...
The aim of the study was to investigate effects dietary lipid on growth and feed utilization Meagre (Argyrosomus regius Asso, 1801), taking into account their feeding behavior collecting food from bottom cages. fish (141.07±0.5g, average weight ± SD; 22.18±0.53 cm, total length± SD) were fed three isonitrogenous experimental diets (45% crude protein, dry matter) containing 16% (group A), 18% B), 20% C) lipids for 570 days. stocked 9 net cages (16 m diameter; 7 deep) at a density 16000 per...
Abstract The growth hormone ( GH ) gene plays a regulatory role in postnatal somatic growth, metabolism, and development vertebrates fish. genetic variations partial region of the its associations with traits were studied using DNA sequencing 200 European sea bass Dicentrarchus labrax individuals. We identified 5 haplotypes (HAP1-5) 10 novel SNPs (g.1557 A > T, g.1611 T C, g.1663 C G, g.1799 g.1824 g.1912 A, g.2052 G C) bass. genotypes locus found to be significantly associated total...
Tüm dünyada olduğu gibi Türkiye’de de su ürünleri yetiştiriciliği büyük bir hızla gelişmektedir. yetiştirilen türler arasında alabalık ilk sıralarda yer almaktadır. Genel olarak üretimi için ticari yatırımların 1970’li yıllarda başladığı bildirilmişse aslında deneme üretimlerinin ve göllerde balıklandırma çalışmalarının 1950’li gerçekleştirildiği dikkati çekmektedir. Prof. Dr. Curt Kosswig öncülüğünde yapılan denemeler ile Abant gölünde 1954 yılında Salmo trutta abanticus Tortonese 1954,...
In this study, the effect of use feeds containing different protein ratios on growth performance juvenile sea bass (Dicentrarchus labrax L., 1758) reared in freshwater was investigated. Sea fry with an average body weight 1.0 ± 0.03 g were stocked 120 liter tanks triplicate after their adaptation to freshwater. The used study had protein/similar fat content. Accordingly, experimental groups named as 45CP (45% CP / 18% CF), 50CP (50% CF) and 55CP (55% CF). At end experiment, highest gain 5.84...
