The journal implements double-blind peer review practiced by specially invited international editorial board members. IntroductionThe ornamental clownfish Amphiprion ocellaris (Pomacentridae) (A. ocellaris) is one of the most popular ornamental marine teleost species. They are artificially bred worldwide to satisfy the demand for the ornamental fish as well as to reduce the catching pressure on the natural ornamental fish stock. In Vietnam, this species was successfully bred and grew in captivity, however, growth and survival rates are still low. Researches have revealed that antibiotics may boost growth and improve feed consumption [1]. In contrast, the use of chemicals and antibiotics carries many risks including toxicity, resistance, residues and possible harm to human health [2]. This has paved the way in finding new replacements for antibiotic [3]. Besides vaccine, probiotics and prebiotics, such as mannan oligosaccharides (MOS) have received high attention.Prebiotics are non-digestible, but it benefits the host by increase in growth and metabolism of healthy intestinal bacteria of the host [3]. Previous research showed prebiotics can boost growth of many aquaculture species [4][5][6][7][8][9][10], boost non-specific immune and pathogen resistance [11] and improve intestinal function and health [4,10,12]. MOS is used commonly in fish and crustacean diet.There are many studies on effects of MOS on aquatic species, however, to the authors' knowledge, MOS requirement for optimal growth of clownfish is still poorly understood. Inclusion dosage of the prebiotics plays a vital role because inappropriate dose may adversely affect the animals [4,13]. Therefore, the present study aimed to define the optimal range of MOS inclusion in diets on growth performance and protein content of clownfish, A. ocellaris. Materials and methods Experimental fish and culture systems Results:The result showed that growth rate was enhanced significantly in fish fed 0.10% and 0.15% MOS in diets compared to fish fed other MOS levels or control (P < 0.05). Survival rate significantly increased in fish fed diets with 0.20% and 0.25% MOS, compared to control. Fraction rates of protein growth were significantly higher in fish fed diets with 0.15%, 0.20% and 0.25% MOS supplementation than those fish fed other MOS inclusion levels and the control (P < 0.04). Dietary MOS concentrations and clownfish growth rates were significantly correlated. Optimal MOS concentration was predicted to be 0.185%, 0.173% and 0.171% at Days 14, 42 and 70, respectively. Conclusions:In conclusion, MOS-supplemented diet benefits for boosting growth, survival and body composition of the clownfish, A. ocellaris.

“…For instance, the administration of lactic acid bacteria, similar to the ones present in Bactocell, improved growth, immunity, and health status as well as reproduction in zebrafsh, Danio rerio [45,46]; increased survival rates in pikeperch, Sander lucioperca larvae [47]; improved stress resistance in Persian sturgeon, Acipenser persicus larvae [48]; and induced higher activity of digestive enzymes in juvenile California halibut, Paralichthys californicus [49]. Moreover, the use of compounds present in AgriMOS has improved growth performance, survival, and immune status of rainbow trout, Oncorhynchus mykiss [50], or enhanced growth performance and feed utilization of the giant freshwater prawn, Macrobrachium rosenbergii juveniles [51].…”

European eel, Anguilla anguilla, larval culture faces a bottleneck during the transition to exogenous feeding. To stimulate gut-priming, in the present study, prebiotics (AgriMOS, mannan-oligosaccharides, and β-(1,3 and 1,6)-poly-D-glucose), probiotics (Bactocell, Pediococcus acidilactici), and synbiotics (AgriMOS + Bactocell) were administered to European eel larvae during the endogenous prefeeding stage. Eel larvae were reared in 2 L incubators with an initial stocking density of ∼200 larvae/L. Each treatment (pre-, pro-, synbiotics, and control), represented by 3 replicated incubators, was connected to a separate recirculating aquaculture system. The gut-priming agents were introduced directly into the rearing water. Results revealed increased mortality when larvae were introduced to synbiotics and impaired growth in connection to probiotics and synbiotics. Larvae receiving prebiotics showed similar survival and growth to larvae reared without gut-priming agents. The immune gene expression revealed a lag phase between maternally inherited protection (c3, igm, and il10) and the gradual buildup of the larvae’s own immune system (il1β, irf7). The lack of treatment-related immune (c3, igm, il10, il1β, and irf7) and stress/repair (hsp70, hsp90) responses revealed an immature immuno-readiness. Digestion (try, ctra, ctrb, tgl, and amyl), food intake (cck), and appetite (ghrl)-related genes were expressed at basal levels already on 4 days post-hatch, which combined with phenotypic plasticity of the appetite-regulating ghrelin (ghrl), indicated a prospective adaptive capability towards earlier maturation of the larval digestive capacity. Overall, we contemplate that the application of gut-priming agents in water has merit; however, as no beneficial effect was observed, we conclude that the regimen applied is not recommendable in the present form and needs to be customized for future eel larval culture. As such, water management strategies and rearing options need to be further explored to establish prefeeding and feeding regimens, targeting optimized culture conditions, and the production of healthy eel offspring.

“…The use of AGRIMOS® (Ag) as a commercial prebiotic containing Mannan oligosaccharides (MOS) and beta-glucan has recently been regarded (Mohamed et al, 2017). The MOS is derived from the cell wall of the yeast Saccharomyces cerevisiae, which as a prebiotic promotes the growth of bene cial intestinal bacteria and improves intestinal digestion and function by stimulating the immune system and pathogenic agents.…”

This study evaluates using different levels of the white button mushroom powder (WBMP) on some mucosal innate immune parameters (lysozyme, protease, esterase, alkaline phosphatase activities, and total immunoglobulin levels), and the relative expression of some principal immune-relevant genes (lysozyme, TNF-α, and IL-1β) in the zebra danio intestine. Zebrafish specimens (1.75 ± 0.25 g) were divided into experimental units based on the additives to a diet including 5, 10, and 20 g of WBMP per kg of food weight, alone or in conjunction with the antibiotic (10 mg/kg BW), and the AGRIMOS (1 g/kg food weight). Following the 11-day experimental duration, the skin mucus and intestine were sampled. To assess the immune gene expression, the real-time PCR detection system was conducted according to the ΔΔCt method using the IQ5 software (Bio-RAD). Results showed that all groups had a significant increase in terms of mucosal lysozyme activity compared to the control group. Examination of total immunoglobulin, protease, esterase, and ALP activity in fish under experimental treatment showed that there was no significant difference between the trial groups and the control groups. The most expression of the lysozyme gene was related to the group that was separately taken the lower concentration (5 g per kg of FW) of WBMP. In conclusion, the amount of 1% mushroom powder in the diet can improve its immune function. Our recommendation is that given the positive effects that mushroom powder added on the diet alone, avoid taking antibiotics for this purpose.
