Medicare spending could be reduced by far more than 3% without harming patients by giving physicians the tools they need to keep patients healthy, avoid unnecessary tests and procedures, reduce avoidable hospitalizations, and prevent infections and complications. Savings from better care could be used to pay for repealing the SGR and for making reasonable annual updates to physician payments...
An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...
The aim of this study was to increase the production efficiency of reared Great sturgeon (Huso huso) in the larval stage (after hatching until absorption of the yolk sac) under the corresponding influence of photoperiod and light intensity. In this study, the larvae from the after hatching to the complete absorption of the yolk sac were exposed to four light intensities (0-10; 70-100; 200-170 a...
This feeding trial was carried out to evaluate the effects of different dietary cadmium levels on growth and tissue cadmium content in juvenile parrotfish, Oplegnathus fasciatus, using cadmium chloride (CdCl2) as the cadmium source. Fifteen fish averaging 5.5±0.06 g (mean±SD) were randomly distributed into each of twenty one rectangular fiber tanks of 30 L capacity. Each tank was then randomly ...
The effect of dietary supplementation DL-alpha-tocopheryl acetate (a-TA) on growth performance, feed efficiency, survival, and salinity resistance Asian catfish (Clarias macrocephalus) fry was evaluated. A total 750 were divided into five treatments with three replicates fed experimental diets containing varying levels alpha-TA: 0, 100, 200, 300, 400 mg·kg-1 diet for 45 days. Results show that ...
Little is known about the growth performance of sex-reversed, all male Oreochromis niloticus under different traditional and non-traditional culture methods practiced in India. In this study, 17"methyltestosterone treated monosex tilapia was cultured in concrete tank, flow-through system, cage, pen and earthen pond. Similar feeding regime and stocking density of fish were maintained for all the...
We used a selection of Arabidopsis thaliana mutants with knockouts in defence genes to demonstrate growth costs of trichome development and glucosinolate production. Four of the seven defence mutants had significantly higher size-standardized growth rates (SGRs) than the wild-type in early life, although this benefit declined as plants grew larger. SGR is known to be a good predictor of success...
Fishmeal, as one of the main protein sources, has become scarce and expensive. This conventional source is no longer considered sustainable. As an alternative, black soldier fly (BSF) a popular non-conventional that been tested in formulation aquafeed to replace fishmeal due its nutritional value, reasonably low price, large abundance. Nevertheless, evidence on BSF supplementation varied among ...
Various kinds of fermented soybean meal are now commercially available, whereas the quality these products is uneven due to different processing technologies, fermentation strains, and raw meal, which would lead effects on bioavailability nutrients in aquaculture feeds. Thus, a 10-week feeding trial was conducted evaluate six available (FSBM) growth performance juvenile turbot (Scophthalmus max...
artemia plays a major role in aquaculture as one of the most important live foods used in larval rearing. the aim of this study was to determine the optimum level of feeding in artemia urmiana with baker's yeast (saccharomyces cerevisiae). triplicate groups were fed with different levels of s. cerevisiae yeast 0.625 (control), 1.25 (t1), 2.50 (t2), 5.0 (t3) (mg yeast per 1000 nauplii) for ...
