“…The improved fish growth and feed utilization may possibly be because of the acceleration of the digestive system maturation and the increased nutrient digestibility (Tovar‐Ramírez et al 2004; Waché et al 2006; Suzer et al 2008; Sáenz de Rodrigáñez et al 2009). Moreover, Buts et al (1994) reported that yeast may release spermine and spermidine in the digestive tract, which play a fundamental role in proliferating, fast growing, and regenerating tissues (Peulen et al 2002). It is therefore possible that spermine and spermidine production by yeasts may partly explain the effect observed on fish growth and feed utilization.…”

The potential use of dietary probiotics to enhance the growth and health of aquatic animals has recently attracted intensive attention. Therefore, this study was conducted to evaluate the growth response of Galilee tilapia, Sarotherodon galilaeus (L.), and its resistance to waterborne copper toxicity. Fish (2.5–3.3 g) were fed a diet containing either 0.0 or 10 g live yeast, Saccharomyces cerevisiae, for 6 wk. After the feeding trial, fish at both diets were exposed to 0.0 or 1 ppm Copper (Cu) for 24 h, or 5 ppm Cu for 1 h (T1, T2, or T3 for groups fed basal control diet and T4, T5, or T6 for groups fed yeast supplement). The growth‐promoting influences of baker's yeast were observed. Feed utilization was significantly improved, and the biochemical parameters such as serum glucose, lipids, and protein increased when fish were fed a yeast‐enriched diet. No significant dietary effects were observed on creatinine, aspartate amninotransferase, and alanine aminotransferase because of yeast supplementation. After Cu exposure, the different biochemical parameters and Cu residues were significantly affected by yeast supplement, Cu levels, postexposure time, and their interactions (P < 0.05). Fish in all treatments biochemically recovered the effect of Cu toxicity within 4–8 days. The comparison of Cu residues in Cu‐treated groups, at the same times, revealed that yeast supplementation reduced Cu absorption and accumulation in fish body (P < 0.05). The obtained results indicate that baker's yeast could be used for Galilee tilapia culture to improve its growth performance and its resistance against the waterborne Cu toxicity.

“…The S. cerevisiae and related yeast species are known to secrete polyamines such as putrescine, spermidine, and spermine (Tabor & Tabor, 1985), which are thought to be essential growth factors. According to Peulen, Deloyer, and Dandrifosse (2002), those polyamines play a fundamental role in proliferation, rapid growth, and regeneration of tissues.…”

There is some evidence that single‐cell proteins such as yeast have the potential to improve feed utilization in aquaculture fish, but this has not been investigated in the economically important dusky kob, Argyrosomus japonicus. This study was, therefore, designed to determine the effect of graded levels of dietary inactivated brewer's yeast, Saccharomyces cerevisiae, on the growth performance and hemobiochemical parameters of dusky kob in a 6‐week feeding period. Five isonitrogenous and isoenergetic diets—consisting of three brewer's yeast‐containing diets at rates of 50,150, and 300 g/kg dry matter (BY5P0, BY15P0, and BY30P0, respectively); a commercial dusky kob diet containing 10% probiotic mix but no brewer's yeast (BY0P1, positive control); and a commercial dusky kob diet with neither the probiotic mix nor the yeast (BY0P0, negative control)—were formulated. A total of 65 fish, weighing an average of 7.02 ± 0.10 g, were randomly distributed to each of 20 replicate tanks. Each dietary treatment was randomly allocated to four tanks and offered to fish at a rate of 2.8% fish body weight per day. A total of 10 fish from each tank were randomly sampled once a week for length and weight measurements. Blood was drawn from five fish per tank (20 fish per treatment) for hematology and serum biochemical analyses at the end of the 6 weeks. Fish on the BY0P0 diet achieved the highest weight gain of 18.53 ± 0.69 g after 6 weeks. Growth rate was significantly reduced in the groups fed BY15P0 and BY30P0 diets compared to the BY0P0, BY0P1, and BY5P0 groups. Fish fed the BY0P0 diet recorded the highest average feed conversion efficiency (FCE) of 0.22, while the BY30P0‐fed group recorded the lowest FCE of 0.15. Hematocrit and alanine transaminase levels declined with increasing levels of yeast. It can be concluded that the maximum inclusion level of brewer's yeast that does not impair growth performance and health of dusky kob is 50 g/kg.

“…D. hansenii HF1 produced much more spermidine than S. cerevisiae X2180, and that might also account for the effects observed in European sea bass (Tovar-Ramírez et al, 2002). More generally, the polyamines play a fundamental role in proliferating, fast growing and regenerating tissues, while their endogenous synthesis appears somewhat insufficient in healthy animals (Peulen et al, 2002). It is therefore possible that polyamine production by yeasts may explain at least partly the effect observed on fish growth and metabolism.…”

Live yeasts in the gut: Natural occurrence, dietary introduction, and their effects on fish health and development

This minireview summarizes the present state of knowledge concerning the importance of yeasts in fish gut. Yeasts have been commonly isolated in the gastrointestinal tract, and high population densities were sometimes noted in healthy fish, but the data were quite variable in terms of colony counts and taxonomical diversity. Rhodotorula sp. seemed relatively frequent in both marine and freshwater fish, and Debaryomyces hansenii has been found to be dominant in rainbow trout. Some other dominant strains have been described, such as Metschnikowia zobelii, Trichosporon cutaneum, and Candida tropicalis in marine fish, and Candida sp., Saccharomyces cerevisiae, and Leucosporidium sp. in rainbow trout. The natural proliferation of yeasts in fish mucus may be generally considered as commensalism, in spite of a few cases of pathological infections mainly due to opportunistic strains. Several strains were documented to settle and grow in fish intestine after experimental introduction, particularly S. cerevisiae and D. hansenii in rainbow trout. There have been a few instances of competition among yeasts in fish intestine, while the effect of yeast on associated bacteria is still unclear. Yeasts can stimulate the immune response in fish. ß-glucans is likely the most important compound in this regard, but some other cell-wall components or soluble factors may also play a role. Both cellular and humoral responses have been educed by dietary yeast, depending on the experimental conditions. Other benefits may be expected for the host, especially the intestinal colonisation of early feeding fry with yeast, which may have some effect on development, e.g. by accelerating the maturation of the digestive system. In older fish, dietary yeast may stimulate metabolism and growth. Such beneficial effects need to be further investigated, either in cases of natural colonisation or after dietary introduction, while trying to elucidate the mode of action, and determine whether cellular viability is a prerequisite for efficacy.
