“…The elevated glycaemia in fish fed the fishmeal‐based diet might be attributed to the high level of starch in this diet, while the relatively low level of amino acids in the plasma of these fish compared to those fed plant proteins might result from the difference in protein levels in the diets (Borey et al., ). It was also suggested that dietary non‐starch polysaccharides might cause some delay in the uptake of amino acids in rainbow trout intestine, when the diet included plant protein sources (Larsen, Dalsgaard, & Pedersen, ). The reduced cholesterolaemia observed in fish fed the plant‐based diets was already observed in rainbow trout when fish meal and fish oil were replaced by plant proteins and vegetable oils, likely reflecting the diet composition (Kaushik et al., ; Lazzarotto et al., ; Richard, Kaushik, Larroquet, Panserat, & Corraze, ; Romarheim et al., ; Zhang et al., ).…”

The shortage of fish meal and fish oil has led to demonstrate the feasibility of omitting marine ingredients from the diet of rainbow trout. This complete suppression was further studied in the present experiment. Plasma markers indicated that the metabolism was deeply affected in trout fed plant ingredients. The pyrosequencing of reverse transcripts of partial 16S ribosomal RNA revealed the composition of the active bacterial community associated with intestinal mucosa. Most differences appeared between trout fed either a marine diet or a commercial‐like diet with large amounts of plant protein sources and oil. One taxonomic unit of Cetobacterium sp. dominated this microbiota, the overall composition of which was highly variable amongst individuals. This variability in trout fed without marine ingredients was less than in the other dietary groups. At the individual level, the relative prevalence of some bacteria correlated with the level of plasma markers, in particular two distinct taxonomic units of the genus Clostridium, which correlated either with plasma glucose or with several spectral regions containing tyrosine and phenylalanine resonances, detected by 1H‐NMR profiling. Such correlations deserve further investigation for identifying the functional roles of intestinal microbiota.

“…Therefore, increasing attention has been paid to the effects of different diets and nutritional status on tissue AA concentrations in both mammal and fish species (Hammarqvist, Andersson, Luo & Wernerman ; Yin, Yao, Liu, Gong, Ruan, Deng, Tan, Liu & Wu ; Larsen et al . ). Up to now, little information is known about the dynamic changes of tissue AA concentrations after FM replaced by MBM in turbot.…”

Meat and bone meal (MBM) is a high‐quality alternative protein source used to replace fishmeal (FM). However, the molecular mechanisms of over‐substituted FM by MBM resulted in growth reduction are still not clear. The objective of the study was to evaluate the effect of FM replacement by MBM on the concentration of postprandial free amino acid (FAA) and mRNA abundance of peptide and amino acid transporters in juvenile turbot (Scophthalmus maximus L.). Fish were fed with FM diet (60% FM), MBM diet (33% FM + 34.2% MBM) and MBM + AA diet (MBM diet with essential amino acid (EAA) added to match the AA profile of FM) for 30 days. Results showed that compared with the FM diet, MBM diet led to a reduction in FAA concentration peak values in plasma and muscle. MBM + AA diet significantly elevated the peak values of FAA concentrations to FM diet level in plasma, but not in muscle. Furthermore, compared with FM diet, MBM diet significantly increased gene expression of PepT1 and major amino acid transporters in intestine, whereas MBM diet greatly downregulated gene expression of T‐type amino acid transporter‐1, system ASC amino acid transporter‐2 and cationic amino acid transporter‐2 in muscle. Supplemented EAA did not ameliorate these different effects in intestine and muscle. Overall, this study provided a comprehensive explanation for the relationship between diet, FAA concentrations and AA transportations, which provides a molecular basis for further using MBM to replace FM in aquafeeds.

“…replacement of fishmeal with plant proteins and recommended the utilization of plant protein mixtures over a single plant protein ingredient due to the ability of the different ingredients to compensate for essential amino acid deficiencies and avoidance of a high inclusion level of any single anti-nutritional factor (Agbo, Madalla, & Jauncey, 2015;Borgeson, Racz, Wilkie, White, & Drew, 2006;De Silva & Anderson, 1995;Larsen, Dalsgaard, & Pedersen, 2012). In this regard, some studies have affirmed that the feeding of mixtures of different plant proteins in diets to fish had comparable growth performance to a fishmeal-based diet and further stated that using plant protein mixtures could significantly reduce or completely replace fishmeal in fish feeds (Aoki, Watanabe, Furuichi, & Tsuda, 1997;Burr, Wolters, Barrows, & Hardy, 2012;Olukunle, 1982).…”

The effect of plant protein‐based diets on apparent nutrient digestibility, growth response, egesta quantity, postprandial ammonia excretion rate and serum quality of Nile tilapia

The study assessed the effect of oilseed meal mixtures on the biological value, faecal matter output, ammonia excretion rates and serum biochemistry of Nile tilapia over 63 days. The experimental diets (PPB 1, PPB 2 and PPB 3) were formulated using four selected oilseed meals that were mixed in different protein proportions to contribute 80% of total dietary crude protein. In each diet, either one or two of the oilseed meals were the dominant protein contributor. A commercial tilapia feed was used as the control diet (CTRL). Sex‐reversed Nile tilapia fingerlings (35 g) were stocked at 20 fish per tank in a recirculation system and fed at 3% body weight of their respective diets. At the end of the study, ADCs of dry matter, crude lipid and ash were significantly (p < .05) lower in all the plant‐based diets compared with the control diet. Fish fed the control diet had significantly higher weight gain and SGR compared with the plant‐based diets. Egesta output was 127% higher in the plant‐based diets compared with the control diet. All dietary treatments exhibited a similar trend in changes in ammonia nitrogen. Nevertheless, serum metabolites levels indicated no significant differences among treatments. Although the PPBs did not affect ADC of protein and serum profile, fish growth was reduced while faecal output increased.
