“…In general, soy lecithin has a total phospholipid content of 62%, in which, phosphatidylcholine is 15%, phosphatidylinositol is 13%, phosphatidylethanolamine is 14% and other phospholipids account for the remaining 20%. Soy lecithin is also known to have antioxidative and chemo‐attractant properties (Hertrampf & Piedad‐Pascual, 2000). Feeding diets with soy lecithin was associated with high survival and growth rates during the early life stages in salmonids (rainbow trout and Atlantic salmon) (Poston, 1990).…”

In this study, we examined the effect of different dietary inclusion levels of soy lecithin on growth, feed utilization, digestive enzyme activity, whole body fatty acid profile, body deformity and survival of milkfish (Chanos chanos) larvae, through a six‐week feeding experiment. During the trial, five isonitrogenous and isoenergetic (~580 g kg−1 protein, 120 g kg−1 lipid and 20.5 MJ kg−1) practical larval diets with different levels of soy lecithin (0, 17.5, 35, 52.5 and 70 g Kg−1 in place of fish oil) were fed to triplicate groups of 18 days post‐hatch milkfish larvae, three times a day, to visual satiation. At the end of the trial, larvae fed SL52.5 diet showed significantly higher final mean body weight (0.81 g), weight gain and specific growth rate, as compared to the other dietary groups. Feed intake was found to increase (0.74–1.54) linearly with increasing inclusion of soy lecithin. Corresponding to growth estimates, SL52.5 group had low FCR (2.37) and higher intestinal lipase activity than the rest. Likewise, the highest larval survival rate was recorded in SL52.5 and SL70. Protein efficiency (PER) was high in SL35, followed by SL52.5 group. The percentage of deformed larvae decreased with higher dietary phospholipid content, albeit with no statistically significant difference. The fatty acid composition of milkfish larvae was apparently independent of the dietary fatty acid content, with no significant dietary correlation. Overall, the results of the present study ascertained the beneficial role of dietary phospholipids in milkfish larval nutrition, and using second‐order polynomial regression analysis, 59.6 g kg−1 soy lecithin was found to be the optimal inclusion level in milkfish larval feeds.

“…The improved FCR reflects enhanced feed utilization in striped catfish, which can be related to enhanced feed intake and digestion. It has been stated that SBL effectively increases lipoproteins formation involved in the digestion of lipids and the absorption of nutrients in fish intestines [ 15 ].…”

“…Lecithin contains fatty acids, phosphate, and choline, which facilitate the metabolism of carbohydrates and lipids [ 14 ]. Phospholipids are involved in the structure of cell membranes and lipoproteins, which are needed for embryonic and larval growth and the luminal emulsification of lipids components [ 15 , 16 ]. Accordingly, lecithin can facilitate the absorption of lipids and digested nutrients through the intestines of fish [ 17 , 18 ].…”

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.

“…Literally means egg yolk in Greek word lekithos , lecithin was first extracted from the egg yolk by a French chemist, Theodore Nicolas Gobley in 1850. Subsequently, soybean lecithin came into worldwide commercial availability in 1921, almost a decade after the introduction of soybean from China into Europe and North America ( 21 , 22 ). Global lecithin market size has exceeded USD 2 billion in 2021 and is forecasted to surpass USD 3.4 billion by 2030 ( 23 ).…”

Soybean lecithin is extensively used as the dietary supplementation of phospholipids in animal production. Soybean lecithin plays significant roles in aquafeed as growth promoter, feed enhancer, immunity modulator and antioxidant activity stimulator for aquaculture species. Besides, soybean lecithin is also reported to help aquaculture species being resilient to physical and chemical stressors. In this review, common sources, chemical structure and mode of action of lecithin, with highlight on soybean lecithin application in aquaculture over four-decadal studies published between 1983 and 2023, were evaluated and summarized. By far, soybean lecithin is best-known for its beneficial effects, availability yet cost-effective for aquafeed formulation. Findings from this review also demonstrate that although nutritional profile of long-chain polyunsaturated fatty acids and phosphatidylcholine from egg yolk and marine sources are superior to those from plant sources such as soybean, it is rather costly for sustainable application in aquafeed formulation. Moreover, commercially available products that incorporate soybean lecithin with other feed additives are promising to boost aquaculture production. Overall, effects of soybean lecithin supplementation are well-recognized on larval and juvenile of aquaculture species which having limited ability to biosynthesis phospholipids de novo, and correspondingly attribute to phospholipid, a primary component of soybean lecithin, that is essential for rapid growth during early stages development. In addition, soybean lecithin supplementation plays a distinguish role in stimulating maturation of gonadal development in the adults, especially for crustaceans.
