“…Based on the relationship between muscle cellularity and fgf6 s expression, this might suggest that the dietary DDGS mainly acts on the expression of fgf6a rather than fgf6b to regulate hypertrophy thus to improve fish growth, while fgf6b might be involved in hyperplasia. These results partially agree with (Abouel Azm et al, 2021; Campos et al, 2010; Xu et al, 2019), however, Xu et al, (2019) also suggested that fgf6b possibly had a role in muscle hypertrophic growth regulation. This differentiation deserves further confirmation.…”

“…Moreover, (Hu et al, 2019) reported that the dietary CSM and rapeseed meal inclusion in grass carp lead to increase muscle hardness, gumminess and chewiness but do not affect cohesiveness and springiness due to anti‐nutritional factors in CSM and rapeseed meal that affect the structure of muscle fibres, which partially agrees with our findings. Likewise, Abouel Azm et al, (2021) confirmed that DDGS dietary inclusion caused a softer cooked flesh texture of grass carp.…”

“…Although it has been suggested that the optimal dietary CSM level was 16.64% in juvenile grass carp diet (Zheng et al, 2012), CSM is usually used lower than this value to avoid the depression of pelleting performance due to the presence of cotton velvet. In addition, the diet formulation and nutritional status in the control diet are usually used in the commercial production for juvenile grass carp culture (Abouel Azm et al, 2021; Tan et al, 2013; Wang et al, 2011). According to our results, 20.6% dietary DDGS level replacing the protein provided by 11% dietary CSM exhibited better growth performance, which indicated that DDGS as alternative protein sources showed high biological value than CSM.…”

Both cottonseed meal (CSM) and dried distiller's grains with solubles (DDGS) are important plant protein sources for fish. This study investigated the effects of dietary DDGS inclusion to replace different portions of CSM on growth performance, muscle texture, health status as well as myogenic‐related genes expression of juvenile grass carp (initial weight: 5 g). A 60‐d feeding trial was performed by feeding fish with three isonitrogenous and isoenergetic diets containing different levels of DDGS (0, 10.3% and 20.6%). The highest growth and feed efficiency occurred at 20.6% DDGS dietary inclusion. Body condition factor, hepatosomatic index, serum ALT and AST as well as hepatic GSH and T‐SOD all showed a downward trend with increasing dietary inclusion of DDGS (p < .05). Collagen content in raw muscle increased with DDGS inclusion. However, DDGS inclusion decreased muscle texture indices and muscle fibre density, while increased muscle fibre diameter (p < .05). Dietary DDGS inclusions significantly upregulated the expression of fgf6a, myh1, myh2 and myh4 in muscle, while downregulated the expression of myod, myf5, myog, mrf4, mstn1, fgf6b and myh7. Overall, dietary DDGS replacing CSM positively affects growth by regulating gene expression involved in myogenesis and hypertrophy, while depressed antioxidant capacity.

“…The analyzed protein levels in the diets were 20.95, 24.83, 27.68, 32.26, 35.98, and 39.76%, respectively. Also, 0.1% yttrium oxide (Y 2 O 3 ) as an indigestible marker for apparent digestibility coefficients (ADCs) determination was added to the experimental diets ( 15 ). Dietary ingredients were ground through an 80-mesh screen, weighed, and thoroughly mixed to homogeneity using a mixer (M-256, South China University of Technology, Guangzhou, China).…”

The aim of this study was to investigate the effect of dietary protein level (soybean meal) on growth performance, flesh quality of grass carp, and the related molecular mechanisms. The results showed that appropriate dietary protein levels improved the growth performance, hardness, and pH of muscle while decreasing muscle crude lipid content and cooking loss and altering the antioxidant capacity and metabolic enzymes activities. In addition, appropriate dietary protein promoted the gene expression of myhc-1, myhc-4, myf5, myod, myog, and fgf6a, whereas inhibited that of myhc-7, myhc-2, mrf4, and mstn. Transcriptome profiling of muscle revealed that the flesh quality-specific differences were related to tight junctions and intramuscular fat (IMF) accumulation. GSEA showed that fatty acid metabolism and oxidative phosphorylation were downregulated in SM5 compared with SM1. To conclude, appropriate protein levels improved the growth and flesh quality by regulating muscle antioxidant capacity and gene expression of myhcs and fat metabolism-related signaling molecules.

BACKGROUND: The discharge of food waste and eutrophication in aquaculture could cause environmental pollution and ecological disasters in the hydrosphere. Herein, a novel model of growing microalgae to recover nutrients from food waste and produce feed substitute for aquaculture is proposed. RESULTS: This study developed different methods to pretreat soybean fermentation effluent (SFE) and assessed the contribution of algal growth to nutrient recovery from SFE. Particularly, change of bacterial community was analyzed to explore the interaction between microalgae and bacteria in SFE remediation. In addition, the inclusion level of microalgae in fish diet was optimized and the effect of fresh microalgae on the aquaculture environment was studied. The results showed that unsterilized SFE with appropriate dilution is favorable for microalgal growth and biomass accumulation. Interaction between microalgae and acidogenic bacteria, including Prevotella sp., Acidaminococcus sp. and Lactobacillus sp., favored nutrient recovery from SFE. Removal efficiency of chemical oxygen demand, total nitrogen, total phosphorus and total ammonia‐nitrogen in SFE reached 95.66%, 35.35%, 57.70% and 42.21%, respectively. As the optimal inclusion level of microalgae in fish diet was set as 25%, body length and weight of Micropterus salmoides increased by 13.85 mm and 1.73 g in 44‐day culture. It was also found that fresh microalgae added in fish diet could effectively keep the ammonia concentration in aquaculture system at a lower level. CONCLUSION: The implementation of this model will be of importance to circular economies integrating food waste remediation and eco‐friendly aquaculture. © 2021 Society of Chemical Industry (SCI).
