An experiment was conducted over a period of 150 days at Can Tho, Vietnam to adapt integrated cage-cum-pond systems to local conditions in Vietnam, to determine appropriate stocking density of selected fish species in cages, to assess growth and production of fishes in both cages and open ponds, and to assess the economic and environmental benefits of this integrated system. Nile tilapia (Oreoc...

The effects of dietary linoleic (LA) and linolenic acids (LN) on growth and immunity of allmale hybrid tilapia, Oreochromis niloticus×Oreochromis aureus , were evaluated for 10 wk. Fish fed 0.12% LA+ 0% LN had the lowest weight gain (WG) but was not significantly different from diets containing 0.5% LA or 0.40% LA+ 1.0% LN. Fish fed 1% LA had the highest WG but did not differ from diets with 0....

The potential of irrigation reservoirs in northern Ghana to support Nile Tilapia (Oreochromis niloticus) production 1 m3 budget cages was assessed over six-months three (Bontanga, Golinga and Libga). Fingerlings with a mean weight 17.0 ± 5.0 g were randomly stocked at 50, 100, 150, 200 250 fish per cage duplicate fed commercial tilapia feed (Raanan, 30% protein level) 3 5% body weight. r...

Nile tilapia fish were individually reared under similar light levels for 8 weeks under five colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (∼452 nm), green (∼516 nm), yellow (∼520 nm) or red (∼628 nm). The effects of light on feeding, latency to begin feeding, growth and feed conversion were measured during the last 4 weeks of the study (i.e., after ac...

The need for protein or the amount of needed by fish sector in Indonesia has never been recorded and known. Although demand aquatic feeds is very high, data related to requirements feed be known determining urgency providing substitutes feed. So, it necessary predict based on a series production data. This study predicted Nile tilapia (Oreochromis niloticus). Three exponential smoothing approac...

The fish brain plays an important role in controlling growth, development, reproduction, and adaptation to environmental change. However, few studies stem from the perspective of whole transcriptome change in a fish brain and its response to long-term hypersaline stress. This study compares the differential transcriptomic responses of juvenile Nile tilapia (Oreochromis niloticus) maintained for...

The Kiss1/GPR54 system has recently been shown to play a key role in the onset of puberty in mammals. Growing evidence suggests that this system is also conserved across vertebrates although very few studies so far have been performed in lower vertebrates. The aims of this study were firstly in the teleost Nile tilapia to screen tissues for GPR54 expression levels, secondly to measure the expre...

We evaluated the survival of Streptococcus agalactiae from naturally infected wild mullet (Liza klunzingeri) and experimentally infected Nile tilapia (Oreochromis niloticus) frozen at 20 and 70 jC, respectively, for an extended period of time. The brain, eye, head kidney, and intestine of individually frozen wild mullet (N = 22), culture positive for S. agalactiae from fresh tissues following a...

The objective of the present study was to investigate the influence of the establishment of dominance relationships and social stress on plasma cortisol and metabolite levels in Nile tilapia (Oreochromis niloticus). During the 30-day experiment, the fish weighing 236 29 g were kept in individual aquaria, except for two pairings lasting 6 h each. Blood samples were taken from the animals befor...

Nile tilapia (Oreochormis niloticus) fishbone is a fish part with unknown composition. After elaboration of flour fishbone of tilapia it was analysede. The results in 100 g of flour were: moisture (14.2%), protein (40.8%), total lipids (25.3%), and ash (18.3%), and mineral (in 100 g) was 2715.9 mg (calcium), 1.3 mg (iron), and 1132.7 mg (phosphorus). A total of 22 fatty acids were detected in f...
