“…Diet change from FM to SBM and BY presents several metabolic and health challenges for farmed fish. When compared to the results of growth of brown bullhead promoted by vitamin C and soybean lecithin 7 , the feed conversion rate of fish in the present study was more effective. The average SGRw values were somewhat lower, compared to the 7 , which can be explained by the older fish category and the less pronounced metabolic rate of the analysed fish in the present study 26 .…”

“…conducted a the long-term feeding trial (6 months) of rainbow trout (Onchorinchus mykiss) with the complete replacement of FM with a combination of vegetable protein and confirmed the significant difference in weight gain only after 12 weeks, thereby highlighting the importance of longer-term feeding studies. Duration of the present feeding study is considered adequate for the investigated species compared to similar research 7,56 . Growth performance retardation was detected in the fish fed 75% and 100% of FM substitution, irrespective of the inclusion of BY.…”

A ten-week feeding trial was carried out to investigate the effects of replacing fishmeal (FM) with soybean meal (SBM) and brewer's yeast (BY) on growth performance, blood parameters, oxidative stress and micromorphology of liver and intestines in brown bullhead (Ameiurus nebulosus L.). fish were fed nine feeds in which FM was replaced with 25%, 50%, 75% and 100% SBM (K1, K2, K3 and K4) and 17% + 8%, 42% + 8%, 67% + 8% and 92% + 8% of SBM/BY combination (K5, K6, K7, K8). Growth indices showed greater outcomes for the K2 group in comparison to all other groups. A decrease in plasma cholesterol and triglycerides concentrations was found after FM replacement. Activity of SOD was higher in groups K4, K7 and K8. The early inflammatory indications with abnormal vacuolization of lamina propria and basal epithelium were present in diets K4 and K8. Hepatocytes were irregular in shape with signs of inflammatory reaction in diet K8. A decreased perimeter of hepatocyte nuclei was detected in all experimental diets when compared with the control. This study demonstrates that the optimal replacement of FM with SBM/BY in brown bullhead diets contains up to 50% of FM replaced with SBM in order to obtain advantageous growth performance and adequate health condition. Aquaculture is one of the fastest growing industries in the food sector. The global supply of fish for human consumption has outpaced population growth in the past five decades-preliminary estimates suggest per capita intakes higher than 20 kg (20.2) 1 , double the level of the 1960s-that is mainly due to aquaculture growth, as the capture fisheries have stagnated in the last few decades. However, in 2010 aquaculture used 73% of global fishmeal production 2. Therefore, Hardy 3 argued that the industry would soon run out of sufficient quantities of fish oil and fishmeal (FM). As a result of increasing demand, limited supply and a dramatic increase in FM price, suitable alternative protein sources for fish feed have recently been intensively studied 4. In modern intensive aquaculture, feed formulations may account for more than 50% of the total production costs. Any reduction in feed costs with preserved health status of fish is bound to have a direct positive effect on the profitability of aquaculture production 5-7. Increasing feed efficiency, especially by improving the metabolic assimilation of dietary nutrients, is of the highest priority in contemporary animal production. The use of protein sources of plant origin as FM replacement in fish feed is a growing trend in the aquaculture industry. In this context, among commercially available plant protein alternatives, de-hulled and extracted SBM has one of the best amino acid balances 8 , except for the low level of methionine 9. It is widely available at competitive prices 3 , and is therefore one of the main dietary protein alternatives to FM in the feed of aquacultured species 10-13. Potential problems in soybean feeding exist due to the existence of antinutritional factors, which can cause malnutrition and lower p...

“…Further, El-Sayed et al [ 21 ] stated that Nile tilapia treated with SBL showed increased carcass protein and lipid contents. High protein content can be related to the role of lecithin, rich in phospholipids, in reducing the energy needed for the biosynthesis of phospholipids [ 54 ]. In addition, increased lipid content results from the depletion of digested and absorbed lipids from the intestines due to SBL feeding [ 55 ].…”

Soybean lecithin (SBL) is usually added to aquafeed as a lipid source because aquatic animals cannot synthesize phospholipids. Hence, this study aimed to investigate the role of SBL on the growth, nutrient consumption, digestive enzyme activity, blood parameters, and antioxidant capability of striped catfish. The fish were fed on five experimental diets with five grading levels of SBL (0, 2, 4, 6, and 8%) for 60 days. The final weight, weight gain, specific growth rate, feed intake, and protein efficiency ratio were markedly higher in striped catfish treated with 2–4% SBL than the control level (0% SBL). However, the lowest feed conversion ratio was in the fish-fed groups of 4–6% SBL. The carcass lipid content was significantly higher in fish fed 2–4% SBL compared to the control level (0% SBL). The lipase, amylase, and protease activities were significantly increased in the fish fed 2–6% SBL compared to 0% SBL-fed group. The gradually increased levels of SBL improved the structural appearance and increased the intestinal villi length and branching appearance. The triglycerides and total cholesterol were increased in the fish fed with 4, 6, and 8% compared to the control level, with the highest being in the fish fed with 8%. The lysozyme activity was higher in the fish fed with 2, 4, and 6% of SBL compared to the control level, with higher activity in the fish fed with 2 and 4% than 6%. Superoxide dismutase, glutathione peroxidase, and catalase activities were increased in the fish fed with 2, 4, and 6% SBL. The malondialdehyde level was lower in the fish fed with 4–6% SBL compared to the control level. The regression analysis revealed that the optimum dose of SBL is required at 3.65–4.42% for better productivity and health performances in striped catfish.

Plant Ingredient diet supplemented with lecithin as fish meal and fish oil alternative affects growth performance, serum biochemical, lipid metabolism and growth‐related gene expression in Nile tilapia

et al. 2021

Nile tilapia (Oreochromis niloticus) are valuable fish in the aquaculture sector because of their rapid growth rate, disease resistance and adaptation to a wide range of environmental conditions (El-Kassas et al., 2020;El-Sayed, 2006). The rapid expansion of this sector including Nile tilapia farming has come to a corresponding increase in food demand (Tran-Ngoc et al., 2019). Fish meal (FM) and fish oil (FO) are considered the main traditional protein and oil sources used in aquaculture diets respectively (El-Saidy & Gaber, 2003;Thompson et al., 2012), because they contain essential nutrients, have a balanced amino acid composition, with suitability for most of the aquaculture species. However, with a marked increase in their price and fluctuations in supply around the world, several studies have been conducted to evaluate possible (complete or partial) replacements, with other alternatives such as plant protein and oil sources, which
