“…The characterization of red drum transient intestinal microbiota by sequencing the V4 region of the 16S rRNA gene using NGS, showed that the bacterial community mainly consisted of the phyla Firmicutes, Proteobacteria, Actinobacteria and Bacteroidota (in decreasing order of relative abundance). This finding has been consistently reported in the intestinal tract of this species [ 12 , 39 , 48 ]. In the present study, the supplementation of these additives influenced alpha-diversity, with the transient intestinal microbiota of fish fed the basal diet presenting a higher diversity using the Shanon diversity index and Pielou’s evenness metrics, both of which are weighted by evenness (i.e., how similarly abundant different taxa are).…”

In the present study, the potential synergism between beneficial lactic acid bacteria (Pediococcus acidilactici) contained in a probiotic and a mixture of fermentable complex carbohydrates and autolyzed brewer’s yeast (or prebiotic) were explored in red drum. Four experimental diets were formulated from practical ingredients, and the basal diet was supplemented with either probiotic, prebiotic, or both supplements. Red drum juveniles (~5.5 g) were offered the four experimental diets for 56 days, and at the end of the feeding trial fish fed diets supplemented with probiotic had significantly better weight gain than those fed the non-supplemented diets, and higher protein content in their whole-body composition. Transient intestinal microbiome alpha and beta diversity were significantly affected by the dietary treatments. Interestingly, a higher relative abundance of the lactic acid genus Pediococcus was observed for fish fed diets supplemented with the prebiotic. A higher relative abundance was also observed for the predicted functions of the microbial metagenome, and many of these pathways involved the biosynthesis of essential amino acids, vitamins, and nucleotides. Even though no potential synergistic effect was observed, the individual inclusion of these prebiotic and probiotic supplements positively affected the intestinal health and growth performance of red drum, respectively.

“…Over the past few decades, the availability of plant‐based protein sources such as soybean meal and corn gluten meal and animal by‐products such as meat and chicken meals has been widely investigated (Gatlin et al, 2007; Hardy, 2010; Shukla et al, 2019). Furthermore, in recent years, research on new raw materials such as insect meal (Mente et al, 2022; Takakuwa, Tanabe, et al, 2022; Yamamoto et al, 2022) and bacterial cell meal (Adeoye et al, 2021; Zhang et al, 2022; Zhu et al, 2022) has also progressed, and attempts to further reduce the usage of FM continue to expand. However, it has been reported that these substitutes have certain disadvantages, such as decreased growth performance (Burr et al, 2012; Chen et al, 2019), low nutrient digestibility (Drew et al, 2007) and feed intake (Arndt et al, 1999; Kissil et al, 2000), increased anti‐nutrient factors (Francis et al, 2001) and deformation of intestinal tissues (Krogdahl et al, 2003; Yamamoto et al, 2007), when included in the feed in excess of permissible levels.…”

We replaced fish meal (FM) with porcine blood meal (BM) in red sea bream (Pagrus major) diets to examine the influence on growth performance. Four experimental diets were prepared to be isonitrogenous and isolipidic by replacing 0%, 10%, 20% and 30% FM protein with BM (BM0, BM10, BM20 and BM30, respectively). After the 8-week feeding trial, the final mean body weight, weight gain, specific growth rate, daily feeding rate, condition factor and survival rate were not significantly different among the treatments (p > 0.05). However, feed efficiency tended to lower linearly as the dietary BM level increased, and no significant difference was observed between the BM20 and BM0 groups (p < 0.05). The protein digestibility in the BM20 and BM30 groups decreased significantly compared with that in the BM0 group (p < 0.05).Fat digestibility decreased significantly in the BM30 group than in other treatment groups (p < 0.05). The total serum protein and total cholesterol concentrations in the BM30 group were the highest among all treatment groups. In conclusion, BM can replace up to 20% of FM in the red sea bream diet without adversely affecting growth performance.

To prevent catfish idiopathic anaemia, diets fortified with iron have been adopted as a regular practice on commercial catfish farms to promote erythropoiesis. However, the effects of prolonged exposure of excess dietary iron on production performance and disease resistance for hybrid catfish (Ictalurus punctatus × I. furcatus) remains unknown. Four experimental diets were supplemented with ferrous monosulphate to provide 0, 500, 1000, and 1500 mg of iron per kg of diet. Groups of 16 hybrid catfish juveniles (~22.4 g) were stocked in each of 20, 110‐L aquaria (n = 5), and experimental diets were offered to the fish to apparent satiation for 12 weeks. At the end of the study, production performance, survival, condition indices, as well as protein and iron retention were unaffected by the dietary treatments. Blood haematocrit and the iron concentration in the whole‐body presented a linear increase with the increasing the dietary iron. The remaining fish from the feeding trial was challenged with Edwardsiella ictaluri. Mortality was mainly observed for the dietary groups treated with iron supplemented diets. The results for this study suggest that iron supplementation beyond the required levels does affect the blood production, and it may increase their susceptibility to E. ictaluri infection.
