“…However, global fishmeal production cannot reach a stable increase like the aquaculture production and the fishmeal price has significantly increased year by year ( 3 ). It is important to search for alternative protein sources to reduce fishmeal utilization in fish diet, and soybean meal has been widely used in advanced aquafeed because of its high protein content and balanced amino acid composition ( 4 ). In China and other main aquaculture countries, the soybean self-production capacity is relatively weak and the global soybean application has been pledged to be restricted which are in the expense of deforestation.…”

Cottonseed protein concentrate (CPC) has been proven to partially replace fishmeal without adverse effects on fish growth performance, while little information is known about the effects on liver health during bacterial infection. In the present study, 15% CPC was included into the diet of juvenile largemouth bass (32.12 ± 0.09g) to replace fishmeal for 8 weeks, with fish growth potential and hepatic inflammatory responses during Nocardia seriolae (N. seriolae) infection systemically evaluated. After adaptation to dietary CPC inclusion, largemouth bass even exhibited better growth potential with higher SGR and WGR during the last three weeks of whole feeding trial, which was accompanied with higher phosphorylation level of TOR signaling and higher mRNA expression level of myogenin (myog). At the end of 8-weeks feeding trial, the histological structure of largemouth bass liver was not significantly affected by dietary CPC inclusion, accompanied with the similar expression level of genes involved in innate and adaptive immunity and comparable abundance of T cells in bass liver. N.seriolae infection induced the pathological changes of bass liver, while such hepatic changes were more serious in CPC group than that in FM group. Additionally, RT-qPCR results also suggested that largemouth bass fed with CPC experienced much higher inflammatory potential both in liver and gill during N. seriolae infection, which was accompanied with higher expression level of genes involved in pyroptosis. Therefore, this study demonstrated that the application of CPC in largemouth bass diet should be careful, which may induce higher inflammatory potential during N. seriolae infection.

“…Ding et al (2019) indicated that replacing 50% to 100% fishmeal with soybean meal damaged intestinal villus structure and caused enteritis of bullfrog (Rana catesbeiana). Zhou (2021) reported that dietary glycinin and b-conglycinin induced intestinal damage and inflammation and thus inhibited growth and development of intestine in Songpu mirror carp by upregulating mRNA levels of apoptosis-related genes. Similar result was also reported by Duan (2019), in which the inclusion of b-conglycinin in grass carp diet caused enterocytes apoptosis and significantly reduced the ISI of fish.…”

Soybean meal is one of the major components of aquatic animal diets, whereas little information is available about the evaluation of soybean meal growth suppression mode of action. A 42-day feeding trial was performed to assess the effects of dietary soybean meal on growth performance, apparent digestibility, intestinal digestive enzyme activity, and muscle growth–related gene expression of Litopenaeus vannamei. A total of 600 shrimp were randomly distributed into 20 tanks with 30 shrimp per tank and four tanks per group. The soybean meal was added to the diets at the rate of 20% (T20), 28% (T28), 35% (T35), 42% (T42), and 50% (T50), respectively. Shrimp were fed with apparent satiation three times daily. Results indicated that the final body weight, weight gain rate, specific growth rate, feed intake, intestinesomatic index, dressed weight percentage, and the apparent digestibility coefficients of dry matter, crude protein, crude lipid, and ash were linearly decreased (p < 0.05), but feed coefficient was linearly increased (p < 0.05) as dietary soybean meal increased from 20% to 50%. The intestinal trypsin and amylase activities were decreased (p < 0.05) as dietary soybean meal increased from 20% to 50%, and reached significance at the level of 35%, 42%, and 50%. Shrimp fed with T20 had higher (p < 0.05) intestinal lipase activity than those fed with other diets. The mRNA relative expression of growth hormone, myogenic regulatory factor 5, and target of rapamycin was downregulated (p < 0.05) as dietary soybean meal increased from 20% to 50%. To conclude, dietary soybean meal exceeded 28% significantly inhibited growth performance of L. vannamei, mainly due to the negative impact of soybean meal on digestion and feed utilization and also the inhibition on the muscle growth and related gene expressions.

“…that juvenile Atlantic Cod show no differences in growth performance when provided a diet with 100% of the fish meal replaced with soy protein concentrate. The digestive system of Atlantic Cod has been described as dynamic and these fish are able to obtain nutrition from a wide variety of ingredients; hence, these characteristics may apply to Burbot as well (Colburn et al 2012;Bruce et al 2021). Bruce et al (2021) demonstrated that inclusions of soybean meal or soy protein concentrate replacing 50% of the fish meal in juvenile Burbot diets led to slower growth.…”

ObjectiveThe primary objective of this study was to determine how soy products affect Burbot Lota lota maculosa growth and gastric evacuation. The secondary objective was to determine the digestibility of common soy products in Burbot.MethodsA 130‐day feed study was conducted with subadult (grow‐out stage) Burbot to evaluate performance with 25% of the dietary fish meal replaced with soybean meal or soy protein concentrate compared with a control diet formulated to resemble a salmonid diet. Additionally, diets from the feed study, along with chironomid meal (a natural forage item), were used to determine Burbot gastric evacuation rates using fish naive to soy. These diets, containing over 12% soy, were applied to fish from the same cohort of Burbot used in the initial feed study. A digestibility assessment was conducted using diets with 30% of the fish meal replaced with soybean meal, soy protein concentrate, and a fermented soybean meal.ResultNo differences in growth performance were observed. The gastric evacuation assessment revealed that soy protein concentrate was evacuated at a significantly higher rate than chironomid meal; however, no other differences in gastric evacuation rates among diets were detectable. Apparent digestibility of protein was significantly higher in the soybean meal, soy protein concentrate, and fermented soybean meal treatments relative to the control diet. Apparent lipid digestibility was significantly lower in the soybean meal diet relative to the control diet; however, neither diet was significantly different from the soy protein concentrate or fermented soybean meal treatments.ConclusionSoy protein is highly digestible in grow‐out‐stage Burbot, these fish can be produced to market size on diets with ≥25% of the fish meal (relative to the experimental control diet) replaced with soybean meal or soy protein concentrate with no impact on growth performance relative to a salmonid diet formulation.
