“…Omar, Merrifield, Peter, Williams, and Davies () reported very good results for yeast Protein Concentrate (YPC) for carp and noted the high BV (Biological Value) of the protein in these products from bioethanol production from cereals. Furthermore, yeast cells are also potent sources of nucleic acids, mannan oligosaccharides (MOS) and β‐glucans that can be used as immune stimulants and growth promoters in fish diets (Hassaan et al, ; Hassaan, Mahmoud et al, ; Øverland et al, ). Also, It has been reported that live Saccharomyces cerevisiae yeast can settle in the intestinal mucosa of rainbow trout (Øverland et al, ) which may have some effect on the fish larval development (i.e., by quickening the maturation of the digestive system, and having prebiotic and probiotic effects).…”

Appraisal of a high protein distiller’s dried grain (DDG) in diets for European sea bass,Dicentrarchus labraxfingerlings on growth performance, haematological status and related gut histology

High protein distiller's dried grains (HP‐DDG) are co‐products of ethanol production that uses prefractionation technology. An 8‐week growth trial was conducted to investigate the effect of partial replacement of soybean meal (SBM) by three levels of HP‐DDG (30%, 40% and 50%) on growth performance, physiological parameters and histological changes of the intestine of European sea bass, Dicentrarchus labrax. The results indicated that an increased dietary level of HP‐DDG of more than 30% significantly increases growth performance and improved the FCR of sea bass. In addition, replacement of SBM by HP‐DDG enhanced feed intake efficiency and the health status of fish. Haematology and serum biochemistry (haemoglobin (Hb), red blood cells (RBCs), white blood cells (WBCs), packed cell volume (PCV %) and humeral immune parameters including total protein, albumin, globulin, cholesterol, lysozyme activity and total antioxidant capacity significantly increased with increase HP‐DDG inclusion levels. The findings of this study indicated that HP‐DDG is a good complementary protein source for inclusion aquaculture diets and levels above 30% as a replacement of SBM did not compromise growth performance and physiological parameters of sea bass while enhancing some important indices of health status in this species.

The use of bromelain as a feed additive in fish diets: Growth performance, intestinal morphology, digestive enzyme and immune response of juvenile Sterlet (Acipenser ruthenus)

et al. 2019

Bromelain is a proteolytic enzyme extracted from Ananas comosus and has great potential to affect several physiological functions. The current study examined the effect of bromelain added to commercial feed at concentrations of 0 g (control), 10 g (B1) and 20 g (B2) per kg diet on growth, feed utilization, intestinal morphology, digestive enzyme and immune response of juvenile Sterlet (Acipenser ruthenus) for 56 days. At the end of this experiment, the highest final body weight was detected in fish fed diet of B2 compared to control. The protein content of whole fish was higher in fish fed diet of B1 and B2, but the content of calcium, iron, copper and zinc was noted lower in fillets of fish fed diet of B1 and B2. Supplementation with bromelain significantly increased the height of mucosal folds, enterocytes and the supranuclear zone of the epithelial cells compared to control diet. The enzymatic activity of lipase and pepsin was significantly (p < 0.05) higher in fish fed diet of B1 and B2. The highest activity of lysozyme, total protein level and total immunoglobulin and the proliferative activity of T and B cells were detected in fish fed diet of B2 compared to control, where no significant (p > 0.05) difference was found in ceruloplasmin, metabolic activity of spleen macrophages and potential killing activity of spleen phagocytes between different treatments.

“…With an ever‐increasing volume of aquaculture activities around the globe comes growing pressure to maximize the efficiency of finfish production whilst at the same time ensuring sustainability. Typically, being the main expenditure in intensive finfish aquaculture, feeds must be formulated to promote fish performance, maintain the health of fish and be economically viable; they must also increasingly conform to the emerging paradigm of extending beyond satisfying basic nutritional requirements (Hassaan et al, , ; Li & Gatlin, ; Meng et al, ). However, modern aquaculture continues to face an array of nutritional restrictions which threaten optimal culture.…”

Dietary nucleotides enhance growth performance, feed efficiency and intestinal functional topography in European Seabass ( Dicentrarchus labrax )

et al. 2019

View full text Add to dashboard Cite

Nucleotides, nucleosides and nucleic acids (NU) have many critical functions in supporting life and increasing evidence suggests that exogenous supply can benefit the health of mammals and fish. For these reasons, a 6-week feeding trial was conducted on juvenile European seabass (Dicentrarchus labrax) with diets containing 0%, 0.15% and 0.3% inclusion of a NU mixture (Laltide ® ) derived from the yeast Saccharomyces cerevisiae. At the end of the study no significant differences were found in fish performance, although a tendency towards better performance was indicated in fish fed the Nu0.3 diet. In relation to histological assessment, a significantly greater perimeter ratio; internal to outer (IP/OP) was observed in the posterior intestine of fish fed supplemental NU. Microvilli heights in the posterior intestine were also shown to be significantly promoted in fish fed NU diets (p < 0.05). Goblet cell abundance was shown to be unaffected by the inclusion of NU in the diet (p > 0.05). Overall, this study indicates that orally administered NU may be effective promoters of gut functional topography with marginal associated improvements to fish performance.Nonetheless, longer exposure and/or commercial scale application, and in diets that were challenging in use of high inclusion levels of plant by-products would potentially amplify improvements in production characteristics, in turn benefiting fish culturists.
