“…Even though several studies have indicated that brewer's yeast is a potential replacer of fishmeal in aquafeed (Essa, Mabrouk, Mohamed, & Michael, re hybrid catfish, Li & Gatlin Iii, ,, re hybrid striped bass; Rumsey, Kinsella, Shetty, & Hughes, re rainbow trout ( Oncorhynchus mykiss ), Lara‐Flores, Olvera‐Novoa, Guzmán‐Méndez, & López‐Madrid, ; Ozório, Portz, Borghesi, & Cyrino, re tilapia; Pongpet, Ponchunchoovong, & Payooha, re Thai Panga ( Pangasianodon hypophthalmus × Pangasius bocourti )), they, in parity with a number of other studies (Gumus et al, re goldfish ( Carassius auratus ); Rumsey, Hughes, & Kinsella, re lake trout ( Salvelinus namaycush ), have indicated that higher levels of replacement were associated with a tendency towards some, or even significant, reduction in growth. Neither in this or our former study using tilapia (Nhi et al, ) was any tendency of reduced growth seen in a biofloc environment with the replacement of fish meal, even if the replacement level in the present study with M. rosenbergii did not exceed 60% replacement.…”

A 90‐day feeding experiment was conducted in order to test spent brewer's yeast as a replacement for fishmeal in diets for giant freshwater prawn (Macrobrachium rosenbergii) reared in either a recirculating aquaculture system (RAS) or a biofloc system. Triplicate groups, each of 20 prawn (6.7 ± 0.03 g), were randomly assigned to 24 identical tanks. Twelve tanks were connected to the RAS, and the other 12 tanks were connected to the biofloc system which were initially supplemented with Bacillus subtilis, molasses and blood meal to achieve a C:N ratio of 20:1. Four iso‐nitrogenous (350 g/kg) and iso‐energetic (19 MJ/kg) diets where 0%, 20%, 40% and 60% of fishmeal protein was replaced by spent brewer's yeast. Neither growth nor survival was affected (p > 0.05) by increasing levels of brewer's yeast. The exception, being fish given 60% replacement with brewer's yeast, reared in biofloc, which displayed a higher (p < 0.05) growth than fish given 40% replacement, reared in clear water. The feed conversion ratio of prawn reared in the biofloc environment was lower than in the clear water. We concluded that spent brewer's yeast represents a possible 60% substitute for fishmeal in giant freshwater prawn diets, especially for prawn reared in a biofloc environment.

“…Furthermore, we also found that certain concentration of YC (Treat3 and Treat4) feeding grass carp for 10 weeks showed good growth performances including the FCR and GR. Similar results have been previously reported that yeast supplementation could also promote growth performances and immune response of human (Possemiers et al ., ), chicks (Gao et al ., ), pigs (Shen et al ., ) and fish species (Essa et al ., ; Huang et al ., ; Ran et al ., ; Berto et al ., ). For example, dietary supplemental YC at 2.5 g kg −1 on chicks distinctively improved the growth performances including the average daily gain and feed conversion (Gao et al ., ).…”

SummaryGut microbiota contributes positively to the physiology of their host. Some feed additives have been suggested to improve livestock health and stimulate growth performance by modulating gut bacteria species. Here, we fed grass carp with 0 (control), 8% (Treat1), 10% (Treat2), 12% (Treat3) and 16% (Treat4) of yeast culture (YC) for 10 weeks. The gut microbiota was analysed by 16S rRNA gene V3‐4 region via an Illumina MiSeq platform. PCoA test showed that gut bacterial communities in the control and Treat3 formed distinctly separate clusters. Although all the groups shared a large size of OTUs as a core microbiota community, a strong distinction existed at genus level. Treat3 contained the highest proportion of the beneficial bacteria and obviously enhanced the capacity of amino acid, lipid metabolism and digestive system. In addition, Treat3 significantly improved the fish growth and increased the liver and serum T‐SOD activities while dramatically decreased the liver GPT and GOT. Collectively, these findings demonstrate the beneficial effects of YC feeding on gut microbiota, growth and biochemical parameters and Treat3 might be the optimal supplementation amount for grass carp, which opens up the possibility that a new feed additive can be developed for healthy aquaculture.

“…There are few studies on hybrid nutrient requirements and performance (Essa, Mabrouk, Mohamed & Micgael, 2011), while many farmers still raise hybrid fish. The hybrid surubim Pseudoplatystoma corruscans 9 Leiarius marmoratus is widely raised in Brazil, due to its high growth index, boneless, tender meat and its easy acceptance of feed from its larval phase.…”

Dietary protein:lipid ratio changes growth, digestive enzyme activity, metabolic profile and haematological parameters in hybrid surubim (Pseudoplatystoma fasciatum × Leiarius marmoratus)

Studies investigating improved protein:lipid ratios based on their effects on growth, nutrient utilization, digestive enzyme activities, blood metabolites and erythogram in tropical carnivorous fish are very scarce. This study evaluated the effect of different protein:lipid ratios on these parameters in the hybrid surubim Pseudoplatystoma corruscans × Leiarius marmoratus. Juvenile fish (8.90 ± 0.94 g initial weight) were fed 3% of total biomass for 60 days using four isoenergetic experimental diets with different protein:lipid ratios (9.00, 4.60, 3.54 and 1.78). Higher growth performance parameters were observed at higher protein:lipid ratios. The activities of intestine total alkaline protease, trypsin and lipase (U/mg protein) were not affected by dietary treatments. Chymotrypsin (U/mg protein) was higher in the 4.60 protein:lipid ratio group. Amylase (U/mg protein) was higher in intermediate groups. Blood glucose, total plasma protein, triglycerides, cholesterol and free amino acids decreased as the protein:lipid ratio decreased. Haematocrit was higher at the 9.00 and 4.60 protein:lipid ratios. Hybrid surubim showed metabolic adaptation to the different protein:lipid ratios tested. These results suggest that the 4.60 protein:lipid ratio showed the best protein‐sparing effect of lipids.
