“…Thus, it has become an industry consensus to develop new raw materials and reduce the use of fish meal and soybean meal in aquafeed. Many protein sources have also been tested in fish diet, including rapeseed meal, peanut meal and many others ( 5 ). However, the main constraint for these alternative sources remains in their much lower production than soybean meal.…”

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.

“…The alternative resources of fish meal can be obtained not only from animals but also from plants. However, compared with fish meal, plant protein sources have some defects, such as anti-nutritional factors enrichment and amino acid imbalance [ 3 , 4 ]. Animal protein sources are the ideal component in animal feed formulation, and they are superior to plant protein sources [ 1 ].…”

Fish by-products are rich in collagen. Hydrolyzed collagen derived from fish by-products was used to replace fish meal to evaluate the effects on muscle quality and glycolipid metabolism of juvenile triploid crucian carp. A total of 240 juvenile fish with body weight of 10.01 ± 0.02 g were divided into four groups and fed four diets for 66 days: fish meal (FM) replaced with hydrolyzed collagen (HC) in 0% (Control), 2% (2% HC), 4% (4% HC), and 6% (6% HC), respectively. The results were as follows: The increased proportion of fish meal replaced with hydrolyzed collagen linearly and quadratically decreased the specific growth rate (SGR) of triploid crucian carp (p < 0.05). Compared with the control group, the SGR and intestinal α-amylase, trypsin and lipase activities in the 4% and 6% HC groups significantly decreased (p < 0.05), while there was no significant difference between the control and 2% HC groups (p > 0.05). Total umami amino acids content, chewiness and myofiber density of muscle in the 4% and 6% HC groups, as well as the essential fatty acids content in all HC groups increased significantly (p < 0.05). All HC groups significantly increased the serum glutathione peroxidase (GSH-Px) activity and decreased the serum malondialdehyde (MDA) content (p < 0.05). When the replacement amount reached 4%, the serum glucose and liver glycogen content, the liver and serum triglyceride (TG) content, and serum total cholesterol (T-CHO) content were significantly reduced (p < 0.05). In addition, the expression levels of insulin-like growth factor-1 (IGF-1) of the liver in all HC groups and lipolysis-related genes (lipoprotein lipase (LPL), carnitine O-palmitoyltransferase 1 (CPT 1) and hydroxyacyl-coenzyme A dehydrogenase (HADH)) of the liver in the 6% of HC group increased significantly (p < 0.05), and the expression levels of lipogenesis-related genes (fatty acid synthase (FAS) and sterol regulatory element-binding protein 1 (SREBP 1)) of the liver in the 4% HC and 6% HC groups decreased significantly (p < 0.05). In conclusion, the replacement of 2% fish meal with hydrolyzed collagen had no negative effects on the growth of triploid crucian carp, while the replacement of 4% fish meal with hydrolyzed collagen decreased SGR, but improved the muscle quality and decreased glycolipid levels. The maximum proportion of hydrolyzed collagen replacing fish meal should not exceed 4%.

“…Due to its global availability, low production prize, balanced amino acid profile in comparison with other plant proteins (Table 1) and origin as a by‐product of the oil industry, rapeseed protein products are being regarded as promising protein sources for aqua feeds 36–39 . The most common by‐product of this rapeseed oil industry is rapeseed meal, which is one of the most traded protein components, second only behind soybean meal 40 . Availability of rapeseed and soybean differs depending on regional soil quality, ambient temperature and national or regional traditions 41 .…”

Reviews in Aquaculture

The aquaculture sector has been the key factor in meeting the growing demand for high-quality food by contributing significantly to the global fish production. The portion of fishmeal in aqua feeds has been decreased significantly in recent years, however, increased production in aquaculture still led to demands of fishmeal that cannot be covered by sustainably caught small pelagic fish. Hence, alternatives for fishmeal in aqua feeds are an inevitable necessity. Different plant proteins have been evaluated in the past and rapeseed proteins are considered valuable protein sources for fishmeal-free aqua feeds. Rapeseed is highly available on a global scale and provides one of the most balanced amino acid composition among plant-based protein sources. Additionally, rapeseed cultivation is characterised by low production costs, ecological and economic benefits in cerealdominated agriculture and provision of two highly nutritive products. Subsequently, rapeseed proteins have been intensely investigated over the past decades and knowledge of the application of these proteins in diets for different species of fish has improved dramatically. However, there is no adequate complete review for the application of rapeseed proteins in aqua feeds. This review outlines and discusses the relevant factors influencing the inclusion of rapeseed proteins as fishmeal alternatives in fish diets and highlights provisional thresholds for anti-nutritive substances as well as future research needs.
