The study is aimed to develop a relevant synbiotic promote growth performance of the whiteleg shrimp, Litopenaeus vannamei. For this, four common natural fiber extracts from Arcera banana, Siamese yellow sweet potato, and white potato were screened for supporting Lactobacillus sp. which was isolated shrimp intestines with probiotic activity, prebiotic score, ability induce bacterial enzyme acti...

aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

three experiments of 60 days duration were conducted in post larval stage of indian white shrimp, fenneropenaeus indicus, to explore the appropriate protein: lipid ratios in their diets. a common ingredient mixture consisting of; fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour and cellulose (filler) was us...

An eleven-week feeding trial was conducted to evaluate the growth effect of partial replacement of fishmeal by the microalga Spirulina platensis in the diet of juvenile Pacific white shrimp Litopenaeus vannamei (Boone). The results clearly indicate that Spirulina platensis constitutes an effective food ingredient for shrimp. Growth rates of a Spirulina-fed group differed highly significantly (p...

Heliconema brooksi n. sp. is described from the shrimp eel, Ophichthus gomesi, in Mississippi Sound. This species is distinguished from other members of the genus by possessing in the male 40 or more tessellated longitudinal ridges, a spicule ratio averaging 1:10.6, 4 precloacal papillae, and 6 postcloacal papillae. Females have a protruding vulvular flap. Both sexes have a prominent sclerotize...

three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (wssv) and transcription of antioxidant enzyme genes in pacific white shrimp litopenaeus vannamei. each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...

Objective. The present study aimed to investigate the presence of vibrios in the hepatopancreas of cultured shrimp. Materials and methods. Vibrios from the hepatopancreas of fifteen samples of five specimens each, of apparently healthy Pacific white shrimp (Litopenaeus vannamei) were isolated, identified and quantified. Results. The vibrio density ranged from 430 to 2,400 MPN g-1 (rs MPN cm-1=-...

During host stress response against virus infection, some animal microRNAs (miRNAs) can be upregulated to restore the virus-caused metabolic disorder of host cells via suppressing the expressions of miRNAs' target genes. These antiviral miRNAs may have antitumor capacity, because tumorigenesis results from metabolic disorder of cells. However, this subject has not been explored. In this study, ...
