“…Our results found that there was a higher muscle fiber density and smaller muscle fiber diameter, as well as greater muscle hardness in the dorsal muscle of the FO, SO and RO trial groups, which is similar to previous results in glass carp [97] and Nile tilapia [96]. In addition, similar to results obtained in striped bass [98], we also found higher hardness and chewiness, higher muscle fiber density and a smaller diameter in the dorsal muscle of the FO, SO and RO groups, which indicates that FO, SO and RO could also improve muscle hardness and chewiness by modulating the muscle fiber density and diameter in largemouth bass (Figure 7) [94,98]. Meanwhile, previous studies have found that glycogen content in muscle was also related to muscle quality [99].…”

“…As for lower levels of hardness, firmness and chewiness in the PO and LO groups, this may be due to the decreasing collagen contents mediated by a lower synthesizing ability [ 90 ]. In addition, previous studies have also found that there is a negative correlation between protease activity and hardness and springiness in muscle [ 94 ]. In general, lower protease activities could decelerate tissue protein hydrolysis and therefore increase muscle hardness and springiness [ 95 ].…”

This study investigated the effects of fish oil (FO), soybean oil (SO), rapeseed oil (RO), peanut oil (PO) and lard oil (LO) on growth, immunity and muscle quality in juvenile largemouth bass. After 8 weeks, the results showed that FO and RO could increase weight gain and serum alkaline phosphatase and apelin values compared with LO (p < 0.05). Except lower crude lipid contents, higher amounts of n-3 polyunsaturated fatty acids (15.83% and 14.64%) were present in the dorsal muscle of the FO and RO groups. Meanwhile, FO and RO could heighten mRNA levels of immune defense molecules (lysozyme, hepcidin, and transforming growth factor β1) compared with PO (p < 0.05). While SO could increase potential inflammatory risk via rising counts of white blood cells, platelets, neutrophils and monocytes, and mRNA levels of interleukins (IL-1β, IL-8, IL-12 and IL-15), FO and RO could improve hardness, chewiness and springiness through increasing amounts of hydroxyproline, collagen and lysyl oxidase, and mRNA levels of collagen 1α2 and prolyl hydroxylase in the fish dorsal muscle. Moreover, FO and RO could improve firmness through increasing glycogen and glycogen synthase 1 levels when compared with LO (p < 0.05). Therefore, these results could provide dietary lipid source references during the feeding process of adult largemouth bass.

“…It has been reported that a higher content of SFAs than unsaturated fatty acids in muscle increases muscle hardness [65]. In addition, the textural properties are affected by the crude lipid content of muscle; for example, muscle hardness tends to increase when the muscle lipid content is low [66]. In this study, muscle tenderness and crude lipid content showed significant reductions when 75% of the dietary FM was replaced by NGCP.…”

In the context of human food shortages, the incorporation of non-grain feedstuff in fish feed deserves more research attention. Here, the feasibility and appropriate ratio of non-grain compound protein (NGCP, containing bovine bone meal, dephenolized cottonseed protein, and blood cell meal) for dietary fishmeal (FM) replacement were explored in golden pompano (Trachinotus ovatus). Four isonitrogenous (45%) and isolipidic (12%) diets (Control, 25NGP, 50NGP, and 75NGP) were prepared. Control contained 24% FM, whereas the FM content of 25NGP, 50NGP, and 75NGP was 18%, 12%, and 6%, respectively, representing a 25%, 50%, and 75% replacement of FM in Control by NGCP. Juvenile golden pompano (initial weight: 9.71 ± 0.04 g) were fed the four diets for 65 days in sea cages. There was no significant difference between the 25NGP and Control groups in terms of weight gain, weight gain rate, and specific growth rate; contents of crude protein, crude lipid, moisture, and ash in muscle and whole fish; muscle textural properties including hardness, chewiness, gumminess, tenderness, springiness, and cohesiveness; and serum biochemical indexes including total protein, albumin, blood urea nitrogen, HDL cholesterol, total cholesterol, and triglycerides. However, the golden pompano in 50NGP and 75NGP experienced nutritional stress, and thus some indicators were negatively affected. In addition, compared to the Control group, the expression levels of genes related to protein metabolism (mtor, s6k1, and 4e-bp1) and lipid metabolism (pparγ, fas, srebp1, and acc1) of the 25NGP group showed no significant difference, but the 4e-bp1 and pparγ of the 75NGP group were significantly upregulated and downregulated, respectively (p < 0.05), which may explain the decline in fish growth performance and muscle quality after 75% FM was replaced by NGCP. The results suggest that at least 25% FM of Control can be replaced by NGCP, achieving a dietary FM content of as low as 18%; however, the replacement of more than 50% of the dietary FM negatively affects the growth and muscle quality of golden pompano.

“…This species is preferred due to its tasty flesh and high nutritional and medicinal value. However, recently, a few studies have reported on the flesh quality of wild and cultured fish of Atlantic salmon Salmo salar [ 11 ], sea bass Dicentrarchus labrax [ 9 ], Nile tilapia Oreochromis niloticus [ 12 ], Coilia nasus Engraulidae [ 13 ], blackspot seabream Pagellus bogaraveo [ 14 ], large yellow croaker Larimichthys crocea [ 15 ], and black rockfish Sebastes schlegelii [ 16 ]; the studies mainly focused on muscle nutritional composition and textural properties, while information on molecular biology was poorly investigated. Muscle quality is a comprehensive characteristic system which is difficult to evaluate in terms of only a few biochemical parameters.…”

The present study aimed to systematically investigate the underlying differences in flesh quality between wild and farmed Monopterus albus. Fifteen healthy M. albus per group with an average body weight of 45 g were sampled to analyze muscle parameters by biochemical indicators, histomorphology, and molecular biology. Compared with the wild fish, the farmed M. albus in flesh had lower crude protein, collagen, lysine, histidine, total amino acids, SFA, n-3 PUFA contents, and n-3/n-6 ratio (p < 0.05), and higher moisture, crude lipid, crude ash, MUFA, n-6PUFA, and total PUFA contents (p < 0.05). The thawing loss, drip loss, steaming loss, and boiling loss in the farmed group were significantly higher, and hardness, springiness, cohesiveness, gumminess, chewiness, and resilience were significantly lower than those in the wild group (p < 0.05). In addition, higher muscle fiber density and lower muscle fiber diameter were observed in wild M. albus (p < 0.05). In muscle transcriptome profiling, differentially expressed genes and enriched pathways are primarily associated with muscle development, protein synthesis, catabolism, lipid metabolism, and immunity. To the best of our knowledge, this is the first investigation that compares the flesh quality between wild and farmed M. albus in terms of biochemistry, histology, and molecular biology levels. Overall, wild M. albus had a higher nutritional value and texture quality than farmed M. albus.
