Effect of dietary vitamin E on growth, muscle composition, hematological and immunological parameters of sub-yearling beluga Huso huso L

This study addressed the issue of the dietary supplements; probiotic, prebiotic and synbiotics considered as functional food ingredients in sturgeon aquaculture. Developments of this strategy have been suggested and practiced as an alternative to antibiotic administration in aquaculture. Sturgeons are commercially valuable species due to their meet and roe, which is made into caviar. Aquaculture of sturgeons up to marketable size has increased during the last decade while disquieting decreases have been noticed of the natural populations. In line with the expand evaluations of microbial dietary supplements and prebiotics in finfish and shellfish aquaculture, the scientific community has also increased their interest in approaches to these issues in sturgeon aquaculture. The present review summarizes and discusses the results on intestinal microbiota of sturgeon species and the effects of probiotic, prebiotic or synbiotic administration on growth performance, gut physiology, intestinal microbiota, immune response and health. Furthermore, this study tries to cover the gaps of existing knowledge and suggest issues that merits further investigations.

“…Because there is no external sexual dimorphism in the some sturgeon, for example, the Russian sturgeon, the development of internal gonads is the only biomarker for sex identification. So far, there are four different internal examination methods for sex identification in sturgeons, including invasive surgery (14,17,27), endoscopy (37), ultrasound (62), and measurement of biochemistry and hormone levels in the blood (4,9,21,47,50). The sex of sturgeons can be confirmed via an endoscopic system with very high accuracy (95%) (29).…”

Discovery and identification of candidate sex-related genes based on transcriptome sequencing of Russian sturgeon (Acipenser gueldenstaedtii) gonads. Physiol Genomics 48: 464 -476, 2016. First published May 6, 2016 doi:10.1152/physiolgenomics.00113.2015.-As the Russian sturgeon (Acipenser gueldenstaedtii) is an important food and is the main source of caviar, it is necessary to discover the genes associated with its sex differentiation. However, the complicated life and maturity cycles of the Russian sturgeon restrict the accurate identification of sex in early development. To generate a first look at specific sex-related genes, we sequenced the transcriptome of gonads in different development stages (1, 2, and 5 yr old stages) with next-generation RNA sequencing. We generated Ͼ60 million raw reads, and the filtered reads were assembled into 263,341 contigs, which produced 38,505 unigenes. Genes involved in signal transduction mechanisms were the most abundant, suggesting that development of sturgeon gonads is under control of signal transduction mechanisms. Differentially expressed gene analysis suggests that more genes for protein synthesis, cytochrome c oxidase subunits, and ribosomal proteins were expressed in female gonads than in male. Meanwhile, male gonads expressed more transposable element transposase, reverse transcriptase, and transposase-related genes than female. In total, 342, 782, and 7,845 genes were detected in intersex, male, and female transcriptomes, respectively. The female gonad expressed more genes than the male gonad, and more genes were involved in female gonadal development. Genes (sox9, foxl2) are differentially expressed in different sexes and may be important sex-related genes in Russian sturgeon. Sox9 genes are responsible for the development of male gonads and foxl2 for female gonads.

“…Although, there are some literatures regarding the application of the dietary Vitamin C and/or E on fishes with immunological assay, but there are no enough results regarding their effects on leukocyte counts. Safarpour-Amlashi et al reported higher lymphocytes in Beluga (Huso huso) fed with the high levels of vitamin E (400 mg/kg diet) for 8 weeks [37]. It has also shown a significant increase of lymphocytes in fish fed vitamin C at an elevated dose for longer periods [20,38].…”

White blood cells (WBC) or Leukocytes are defense mechanism indicators in fishes. Vitamins C and E are among the most important nutrients, providing protection to the leukocytes and subsequently influence the fish health and immune system. This study was conducted to investigate the effects of different levels of vitamins C and E (0, 100, 200 and 1000 mg/kg diet) on leukocyte counts of rainbow trout fingerlings during 60 days of feeding trials. The results showed that vitamin E administration increases significantly (P<0.05) the percent of the lymphocytes at 200 and 1000 mg/kg treatments. In addition, a significant increase (P<0.05) was found in lymphocytes of fish fed with 1000 mg/kg vitamin C administration. No significant effects of different levels of Vitamins C and E on neutrophils, eosinophils and monocytes were found during the 60 days experiment (P>0.05). The results revealed that administration of Vitamins C and E can be led to a significant increase in lymphocytes that may influence immune response and resistance against disease.
