“…However, with full results considered, the recommended replacement level was 18.75%. Except for slight changes in whole-body moisture and crude protein, substitution of ECGGR for fishmeal had little influence on the whole-body crude lipid and proximate composition of muscles, which is consistent with other research on black seabream [30], gilthead seabream [36], red drum [37], Florida pompano [33], mirror crap [31], sobaity seabream [38], red porgy [39], and golden pompano [40]. The quality of aquatic products is inextricably linked to the amino acid composition of flesh.…”

Fishmeal is an important protein source in aquafeed. However, due to the limited natural resources, fishmeal is in short supply, resulting in a price surge for fishmeal. Here, we reported a kind of Chinese medicine residue, endothelium corneum gigeriae galli residue (ECGGR), as a fishmeal substitute in the diets of Trachinotus ovatus. Six isonitrogenous and isolipidic diets were formulated, substituting fishmeal at 0%, 6.25%, 12.5%, 18.75%, 25%, and 31.25%. There was no significant difference in the growth performance when the fishmeal substitution level was no more than 25%. The smallest FCR was obtained at the 18.75% substitution level. Furthermore, substituting ECGGR for fishmeal had no effect on whole-body and muscle proximate compositions, except when the replacement level exceeded 25%, which led to a decrease in whole-body moisture and an increase in whole-body crude protein. The contents of Gly, Cys, Ile, Tyr, Pro, and EAAs/TAAs were altered as the substitution level varied. However, dietary replacement of fishmeal with ECGGR did not degrade muscle protein quality, according to a nutritional evaluation of muscle essential amino acid composition. In terms of hepatic antioxidant capacity, neither the overall antioxidant status nor the expression of genes in the Nrf2-ARE pathway was altered by dietary ECGGR. Moreover, the expressions of p65, TNF-α, and IL-8 in the intestine were upregulated at the 31.25% substitution level. Also, more goblet cells were observed in the intestine at substitution levels of 25% and 31.25%. In conclusion, ECGGR can substitute for fishmeal at the optimal level of 18.75% without adversely affecting the growth performance, protein quality, or hepatic and intestinal health of golden pompano.

The limited availability of tubifex poses a challenge in obtaining green catfish fry. Fish oil, comprising saturated and unsaturated fatty acids, serves as an alternative fat source in commercial feed. Utilizing by-products from catfish processing, fish oil production has garnered attention; however, its rich unsaturated fatty acid content renders it prone to oxidation. Vitamin E emerges as a potential antioxidant to curb this oxidation. This study aims to evaluate fish oil quality with vitamin E supplementation. Peroxide number (PV) and storage duration (0, 3, 6, 9, 12, and 15 days) were analyzed. Fish oil received varying doses of vitamin E (0, 1, 3, 5, and 7 mg/100 g), with each treatment replicated twice. Findings indicated that without vitamin E (0 mg/100 g), PV reached 10.0 meq/kg after 15 days of storage. Conversely, with vitamin E (1, 3, 5, and 7 mg/100 g), PV values after 15 days were 7.2, 6.0, 5.4, and 4.0 meq/kg respectively. The study establishes that higher vitamin E doses effectively prolong fish oil shelf life while conforming to the Codex PV standard (≤ 5 meq/kg).

“…This species can easily transition from consuming live food to inert diets during their juvenile stages, and their broodstock spawning technology is well-established, and then allowing the production of fingerlings year-round [ 8 ]. Even though the red drum has a stenophagous feeding behavior in the wild, in captivity, it can readily consume diets containing low levels of fish-derived ingredients without any apparent detrimental effects [ 9 , 10 , 11 ]; nevertheless, it is still paramount to investigate strategies to improve red drum nutrient uptake, modulate their immune responses and balance their intestinal microbiota when fed diets formulated with low levels of marine derived ingredients. The objective of this study was to evaluate the dietary supplementation of Bactocell ® and Grobiotic ® -A individually or their combination on juvenile red drum.…”

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.
