“…Coho salmon (Oncorhynchus kisutch) has gradually become a vital choice for salmon farming because of its polyunsaturated fatty acids, vitamins and minerals, delicious taste, and high economic value [22][23][24]. FM is considered by far the most advantageous protein source for coho salmon, and 0.7 kg of marine protein was used to produce 1 kg of salmon protein, so the farmed salmon is thus a net producer of marine protein [25].…”

In this study, we evaluated the effects of fermented soybean meal (FSBM) or/and unfermented SBM replacing a portion of fish meal (FM) on the growth performance, antioxidant capacity, immunity, and mechanistic target of rapamycin (mTOR) signaling pathway of juvenile coho salmon (Oncorhynchus kisutch). Four groups of juvenile coho salmon (initial weight 152.23 ± 3.21 g) in triplicate were fed for 12 weeks on four different iso-nitrogen and iso-lipid experimental diets: G0 diet (28% FM protein, control group), G1 diet (18% FM protein and 10% SBM protein), G2 diet (18% FM protein, 5% SBM protein, and 5% FSBM protein), and G3 diet (18% FM protein and 10% FSBM protein). The main results were compared with the G0 diet; the weight gain rate, specific growth rate, and condition factor of juveniles in G3 were increased significantly ( p < 0.05 ). The content of muscle crude protein, the total protein, glucose, albumin, total cholesterol in serum, and the total antioxidant capacity in the liver of juveniles in G3 was increased significantly ( p < 0.05 ). The activities of pepsin, trypsin, α-amylase, and lipase in the intestine, the superoxide dismutase, catalase, and alkaline phosphatase in the liver of juveniles in G3 were increased significantly ( p < 0.05 ). The expression levels of phosphatidylinositide 3-kinases, serine/threonine kinase, mTOR, and ribosomal protein S6 kinase 1 genes in the liver of juveniles in G3 were upregulated significantly ( p < 0.05 ). The feed coefficient ratio, viscerosomatic index, the contents of muscle moisture, and malondialdehyde in the liver of juveniles in G3 were decreased significantly ( p < 0.05 ). The expression levels of tumor necrosis factor α, interleukin 1β, and interleukin 6 genes in the liver of juveniles in G3 were downregulated significantly ( p < 0.05 ). However, there was no significant effect ( p > 0.05 ) on the survival rate, food intake, and muscle crude lipid and ash of juveniles among the experimental groups. In conclusion, FSBM to replace a portion FM had a positive effect on the growth performance, protein deposition, antioxidant enzyme activity, digestive enzyme activity, protein synthesis, and immune-related genes of juvenile coho salmon.

“…Coho salmon ( Oncorhynchus kisutch ) represent one of the five major salmon populations in the Pacific and are an important breed of farmed salmon in China. In recent years, the consumer demand for coho salmon has grown rapidly due to its rich nutritional content, which comprises polyunsaturated fatty acids, vitamins, and minerals (Gaffney et al, 2020; Song et al, 2021). Therefore, coho salmon were used as the research subject in the present study.…”

This study investigated the effect of replacing a portion of fish meal with unfermented and/or fermented soybean meal in juvenile coho salmon (Oncorhynchus kisutch). Four groups of juveniles (initial weight 110.31 ± 3.12 g) in triplicate were fed for 90 days on four different iso‐nitrogen and iso‐lipid diets. The G0 diet comprised 28% fish meal protein (control group). In the other three diets (G1, G2, and G3), 10% of the fish meal protein was replaced with unfermented and/or fermented soybean meal protein. The main results were: Compared with G0, the WGR, SGR, CF; the contents of GLU, TP, ALB, T‐CHO, and T‐AOC, the activities of AKP, CAT, SOD, GST, GSH‐PX, O2·‐CR, OH·‐CR, and GSH and the expressions of SOD, GSH‐PX, GST, CAT, and Nrf2 genes of juvenile coho salmon in G3 were significantly (p < 0.05) increased, However, the FCR, HSI, the content of MDA, and the expressions of TNF‐α and IL‐6 genes of juvenile coho salmon in G3 were significantly (p < 0.05) decreased. There was no significant effect (p > 0.05) of diet on their survival rate (SR). In conclusion, the fermented soybean meal in the juvenile coho salmon diet can replace 10% of the fish meal protein.

“…Coho salmon (Oncorhynchus kisutch) is one of the commercially important cultured salmon species in China. In recent years, as living standards improve, consumer demand for salmon is growing fast (Gaffney et al, 2020). Moreover, Cu, along with iron and selenium, controls the activity of SOD and CAT, thus cells from the influence of oxidative damage (Damasceno et al, 2016).…”

Copper (Cu) is an essential microelement required for normal growth and metabolism by crustaceans and fish (NRC, 2011). As a component of metalloenzymes, Cu functions as a cofactor working on catalytic properties of anti-oxidant enzymes that are involved in oxidation-reduction reactions (Gropper et al., 2005;Turnlund, 1999;Uauy et al., 1998). It is also essential for haemoglobin synthesis, red blood cell maturation and formation of bone cells, collagen and elastin (Lall, 2002).Fish mainly obtain microelements from the diet except the proportion that can be absorbed from the water (Lall & Bishop, 1977). Supplementation of trace elements is essential in fish diets (Apines-Amar et al., 2004;Lall, 2002). Cu is a vital component of superoxide dismutase (SOD) that are mainly expressed in liver (Tan et al., 2011;
