This study examined the influence of different carotenoids on growth and some immune indices in rainbow trout. Six semipurified casein-based diets were formulated to contain one three carotenoids: astaxanthin, canthaxanthin β-carotene, at 100 mg kg−1, each them with vitamins A, C E either added or omitted. The two control contained no without vitamins. Rainbow trout weighing about 140 g fed for 9 weeks. Specific rate, feed:gain ratio nonspecific parameters determined. Growth feed conversion...
Although the immune system of shrimps is not comparable to that vertebrates, can acquire protection against pathogenic challenge by building up immunity. In this study, formalin-inactivated virus (FIV) was administered injection, bath-immersion, or orally determine levels vaccination-mediated white spot syndrome (WSSV). Diets supplemented with alfalfa, methyl sulfonyl methane (MSM), wheat grass were provided without FIV. Shrimp injected FIV and challenged 3, 15, 30 days after vaccination had...
The beneficial effects of PHB as supplement for giant tiger prawn Penaeus monodon postlarvae using a short-term enrichment strategy via Artemia were examined. co-supplementing with lipid emulsion also evaluated to determine whether it yielded an additional benefit. Results on the average weight and larval development not significantly different among fed dietary treatments, indicating that supplementation could be used stimulate growth in P. while such positive results have been reported...
Abstract Onion Allium cepa and ginger Zingiber officinale have health-promoting properties that qualify them as functional foods. The effect of repeated acute stressors was examined in juvenile Brown-marbled Grouper Epinephelus fuscoguttatus were fed four diets supplemented with onion at 1.8%, vitamin C 0.86%, β-glucan 0.8% the diet. non-supplemented diet served control. After 12 weeks feeding, fish exposed to experimentally infected a pathogen, bacterium Vibrio harveyi JML1. exposure...
Preventing the transboundary movement of fish viral pathogens in a global environment requires active surveillance. This study examined presence three emerging among koi, common, grass, and silver carp Cambodia, Lao PDR, Myanmar, Philippines, Vietnam. The stud- ied viruses included koi herpesvirus (KHV), spring viremia virus (SVCV), grass reovirus (GCRV). Detection methods consisted isolation by cell culture, infection assay naive fish, polymerase chain reaction (PCR), reverse-transcriptase...
The antibacterial properties of the microalgae Chaetoceros calcitrans were assessed.Samples C. first extracted in methanol, and then different organic solvents increasing polarity, n-hexane (n-Hex), dichloromethane (DCM) ethyl acetate (EA) by liquid-liquid extraction.Solvent extracts screened for activity against four species bacteria: Gram positive, Staphylococcus aureus Bacillus subtilis; negative, Escherichia coli Vibrio harveyi, with Amoxicillin as positive control, N-Hex extract,...
In has increasingly been observed that viral and bacterial coinfection frequently occurs among cultured shrimp this could exacerbate the disease phenotype. Here, we describe a newly discovered strain, Vibrio harveyi PH1009 collected from Masbate Island, Philippines was found to be co-infecting with White Spot Syndrome virus in sample of black tiger prawn, Penaeus monodon. The genome V. sequenced, assembled, annotated. Average Nucleotide identity calculation strains confirmed its taxonomic...
There is increased interest in the development of virus‐resistant or improved shrimp stock because production currently hindered by outbreaks and limited understanding defense. Recent advancement now allows for high‐throughput molecular studies on immunity. We used next‐generation sequencing (NGS) coupled with suppression subtractive hybridization (SSH) to generate a transcriptome database genes from tiger that survived White spot syndrome virus (WSSV) challenge. A total 9,597 unique...
