This study examined the feeding performance of cultured larvae of the greenback flounder Rhombosolea tapirina, using the live feed organisms, Brachionus plicatilis and Artemia sp., to determine the primary sensory modality involved in feeding, and the effect of previous exposure to prey on subsequent prey selection. The proportion of larvae that fed on rotifers in the light Ž y1 y2 . 400–700 nm...

A feeding trial was conducted to investigate the efficacy of Pediococcus acidlactici (Bactocell®) or Baccillus cereus (Toyocerin®)-based probiotics on turkey’s performance, carcass yield, blood parameters and intestinal morphology. A total of 240 1- day-old male Nicholas turkey poults were allocated into three dietary groups with four replicates. A corn-soybean-based diet was used as a basal di...

Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture.  In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...

This study was conducted to evaluate the effect of different fresh feed supplemented to commercial diet on growth and survival of Oscar fish (Astronauts ocellatus) (initial weight: 1.58-1.70 g) during 60-day period. The husbandry environment consisted of glass aquariums appropriate to growth with a photoperiod cycle of 12 L: 12 D. The water temperature was kept at 28 ±1°C. 360 fries of Oscar (i...

Enrichment of live foods by essential nutrients such as highly unsaturated fatty acids is an important tool for improvement of larval fish quality. In this study, nutritional effects of Artemia urmiana enriched by fish and plant oils on growth, survival rate, body compositions and resistance against thermal, salinity and hypoxic stresses in rainbow trout, Oncorhynchus mykiss were examined. Six ...

the present study tried to investigate the effects of probiotic, pediococcus acidilactici in concentrations of 1× 109, 2× 109 and 3×109cfu kg-1 diet on growth and survival rate of oriental bream fry (abramis brama orientalis, berg 1949) in comparison to control diet (devoid of probiotic) for 60 days. in so doing, 180 specimens of oriental bream with initial weight of 2.69± 0.22 g were divided r...

the aim of this study was to evaluate the effects of enrichment of artemia with sea weed extract (padina sp.) on the survival and growth rates of post larvae of western white shrimp (litopenaeus vannamei). this investigation was conducted in the shrimp research center, bushehr, iran. the experimental design was done in three dietary treatments with three replications which were conducted in 9 w...
