“…In contrast, the PL-deficient diet was reported to cause epithelial damage in the intestinal lumen of Arctic char larvae (Olsen et al, 1999). In line with that, our recent study in yellow drum larvae found that the high inclusion of dietary PLs induced increased fatty acid β-oxidation, which provided energy for the proliferation of enterocytes and eventually improved intestinal morphology (Tan et al, 2022). The rapid proliferation of enterocytes requires a considerable amount of energy, and dietary PL inclusion can serve as a preferential energy source during larval growth and development (Penn et al, 2011).…”

“…However, dietary PL source and level showed no significant effect on the mid-intestinal enterocyte height of Atlantic salmon (Salmo salar) larvae (Taylor et al, 2015). Our recent study discovered that the high inclusion level of dietary SL led to intestinal morphology development in yellow drum (Nibea albiflora) larvae (Tan et al, 2022). Further studies are warranted to confirm whether dietary PL inclusion can improve intestinal morphology.…”

“…Therefore, the improved mid-intestine morphology could probably contribute to exogenous nutrient acquisition in larvae fed diets with high SL contents. The possible molecular mechanism was likely caused by the significantly increased mitochondrial fatty acid oxidation and energy production, as mitochondrial fatty acid β-oxidation key genes (ppara and cpt1) in larvae fed a high soybean lectin inclusion diet were significantly enhanced (Carmona-Antoñanzas et al, 2015;Cai et al, 2016;Tan et al, 2022).…”

Investigations have demonstrated a strong and positive association between dietary intact phospholipid (PL) inclusion and aquatic larval growth, nevertheless, the precise molecular mechanism underlying PL inclusion on growth performance has not been well elucidated. This study aimed to investigate the effects of dietary soybean lecithin (SL) inclusion on growth performance, liver metabolism, resistance to hypoxia stress, and potential molecular mechanisms in rock bream (Oplegnathus fasciatus) larvae. Four types of equal-protein and equal-lipid content microdiets (MDs) were formulated with graded levels of SL to achieve phospholipid levels of (PLs, dry matter) 3.84% (SL0), 6.71% (SL4), 9.38% (SL8), and 12.21% (SL12). Rock bream larvae (25 days post-hatching) were fed the respective MDs for 30 days with three replicates. We found that dietary SL inclusion promoted growth performance, survival rate, and stress resistance to hypoxia stress. The increased dietary SL inclusion improved intestinal structure, as shown by the increased perimeter ratio, muscular thickness, and mucosal fold height of the mid-intestinal tissue. Moreover, a high SL inclusion diet (SL12) increased the activity of the key lipolysis-related enzyme (lipase [LP]) in liver tissue but decreased the activity of amino acid catabolism-related enzymes (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]). RNA sequencing results in liver tissue revealed that the SL12 diet increased the transcriptional level of fatty acid activation-related genes (acsl6 and acsbg2), phospholipid catabolism-related genes (acat2, lpin2, and crls), and amino acid synthesis-related genes (gs, csb, aldh18a1, and oct), but decreased the expression of amino acid catabolism-related gene gprt2. Notably, the SL12 diet significantly increased the expression of ribosome biogenesis-related genes (pes1, nop56, nop58, and rpf2) in liver tissue. The ribosome protein-related pathways were the most enriched pathways mapped in the GO database. Collectively, this study demonstrated the necessity of dietary SL for survival, growth performance, promotion of mid-intestinal morphology, and hypoxia stress during the rock bream larval stage. The SL-induced growth performance promotion was likely attributed to increasing nutrient acquisition by intestinal morphology improvement and to increasing SL catabolism and thereby sparing amino acids for protein synthesis.

“…For food digestion, absorption, and subsequent nutrient acquisition, a well-developed intestinal structure is crucial. In a recent study, we found that intestinal morphology development in larvae of yellow drum ( Nibea albiflora ) and this species was influenced by the high inclusion level of dietary SL [ 19 , 20 ]. The liver is the central digestive organ that plays a significant part in the anabolism, catabolism, and reallocate of nutrients, primarily proteins and lipids.…”

This study is aimed at establishing optimal soybean lecithin (SL) enrichment protocols in Artemia nauplii and at comparing the growth performance, body composition, and liver tissue metabolism in rock bream (Oplegnathus fasciatus) larvae reared on SL-enriched Artemia nauplii or SL-enriched microdiet (MD). The enrichment protocol experiment results indicated 12 h enrichment, and 10 g SL/m3 seawater could obtain desirable results. Rock bream larvae (25 days posthatching (dph)) were fed Artemia nauplii or MD for 30 days with three replicates. At stage 1 (larval 25–40 dph), significantly higher growth performance was observed in larvae fed the live prey ( P < 0.05 ). Conversely, at stage 2 (41–55 dph), feeding with MD significantly increased larval standard length, and specific growth rate compared with those of larvae fed live prey. Larvae fed a MD showed decreased lipolysis-related lipase activity as well as decreased amino acid catabolism-related alanine aminotransferase and aspartate aminotransferase enzyme activities in liver tissue. RNA sequencing revealed that feeding with the MD primarily increased the expression of lipogenesis-related genes and protein translation-related gene expression in the liver tissue. Notably, feeding with MD significantly increased ribosome biogenesis-related genes as well as mitochondria synthesis-related gene expression, indicating a high protein anabolism rate and high energy production in liver tissue. In conclusion, 10 g SL/m3 seawater and 12 h could effectively enrich SL in Artemia nauplii. Retard weaning onto MD led to lower growth performance, which was likely due to the diversity of lipid and protein metabolism.
