We conducted this study to determine the chronic effects of Azadirachtin on growth parameters, survival and gill morphology of grass carp [Ctenopharyngodon idella (C. idella)] with an average weight of 11.09±2.3g. We equally distributed 120 fish between three treatments and a control group, with three replicates each. Sublethal concentrations of poison, 0.073 (10% LC50), 0.15 (20% LC50), 0.22...
Recently, the nutritional requirements of marine finfish larvae have received considerable attention, and studies have shown that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and arachidonic acid (ARA) affects the growth and survival of marine finfish larvae. This study investigated the effects of different Artemia enrichments containing variable amounts of DHA and EPA on the gro...
The improvement of immune system and increasing growth and survival of fishes especially at early stages is important for fish culturists. Considering the effects of herbal immunostimulants on innate immunity and growth of fish, the impacts of dietary Salvia macrosiphon extract on some growth and immunological parameters of fingerlings Pangasianodon hypophthalmus were investigated. Fishwith mea...
Background and Objectives: Retinoblastoma is the most common intraocular pediatric malignancy. Angiogenic factor expression such as VEGF (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. This study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ sur...
The objective of this project is to compare growth and survival rate in Chinese carps reared under traditional culture conditions versus those reared in ponds treated with slurry (anaerobic fermented of cow manure). This experiment was conducted using two treatments one treatment using slurry and the other using cow manure plus chemical fertilizer as the control with three replicates for each....
Early autumnal and late spring frosts usually impose damages to wheat production in North-West of Iran. In order to investigate cold tolerance of wheat genotypes, two laboratory and field experiments were carried out at three planting dates of 12 Oct. and 1 and 21 Nov. 2007 in Saatlu Agricultural Research Station on 15 genotypes with winter, facultative and spring-growth types. Arrangement of t...
abstract this investigation was conducted to replace artificial food with gammarus and study this effect on survival and growth parameters of jewel in case of completely randomized design with 3 treatments and 3 replicates in each treatments. 270 jewel fishes with initial mean weight of 1.22±0.72 were reared in 9 aquariums (30 fishes in each aquarium) with volume of 100 liter water. experimenta...
This study aimed to evaluate the effects of using Artemia franciscana enriched with cod liver oil and vitamins C and E on the growth, survival and stress resistance of juvenile Sepia pharaonis (Pharaoh cuttlefish). Twenty-five days after hatching, the larvae of S. pharaonis were transferred into culture tanks with an average length of 15.97±0.15 mm and average body weight of 3.53±0.03 g, in ele...
introduction: hyperglycemia is a common problem encountered in hospitalized patients, especially in critically ill patients due to stress and using parenteral nutrition. uncontrolled hyperglycemia may be associated with increased infection risk. the principal benefit of intensive insulin therapy is a decrease in infection-related complications and mortality. the aim of this study was the assess...
Using probiotics can control pathogens by a variety of mechanisms. Probiotics can promote growth performance and have, therefore, become increasingly important in the aquaculture industry. Convict Cichlid belongs to the family of Cichlidae and is known for its rapid development in laboratory conditions and is suitable for behavioral examinations. The aim of this study was to evaluate the effect...
