“…Additionally, several studies have evaluated the inclusion of bacterial protein in species with high dietary protein requirements like rainbow trout ( Oncorhynchus mykiss ), Japanese yellowtail ( Seriola quinqueradiata ), turbot ( Scophthalmus maximus L.), and red sea bream ( Pagrus major ) ( Biswas et al, 2020 ; Biswas et al, 2021 ; Rajesh et al, 2022 ; Zheng et al, 2023 ). A study conducted by Rajesh et al (2022) for rainbow trout, concluded that the bacterial protein can be included safely at 12.5% when fishmeal inclusion is 37%.…”

“…The results showed no differences among treatments for growth parameters, whole body composition, and digestibility of nutrients, proving that replacement of fishmeal can reach 30% if an attractant is incorporated. Zheng et al (2023) evaluated the inclusion of bacterial protein in diets for turbot at inclusion levels from 9.2% to 61.1% in the diet. The study revealed positive effects on growth performance indices up to 18.3% inclusion.…”

Single-cell ingredients (SCI) are considered promising nutrient sources which are produced using environmentally friendly biotechnological processes. The aim of the current study was to evaluate the replacement of fishmeal, plant protein sources, and fish oil with SCI in organic feeds for European sea bass (Dicentrarchus labrax). Bacterial protein, yeast protein, and microalgae were used to replace fishmeal trimmings, soya bean meal, and fish oil from trimmings. Triplicate groups (30 fish per replicate) of European sea bass (14.4 ± 2.4 g) were fed the experimental diets for 71 days. The results showed that the incorporation of SCI at all levels of inclusion significantly enhanced nutrient digestibility. Additionally, growth performance parameters were not affected by SCI inclusion, exhibiting similar or improved values. Moreover, a tendency for improved anterior and posterior gut structure was observed and a significant increase of lysozyme activity at the two highest inclusion levels of SCI was determined. Overall, the results showed that the inclusion of SCI at 15% (bacterial: yeast: algae—9.4: 4.7: 1) is possible without compromising any of the parameters evaluated. According to these findings, a higher substitution of fishmeal trimmings, plant protein sources, and fish oil from trimmings with SCI in organic diets for European sea bass (D. labrax) can be further evaluated in future studies.

“…In the intestine of mammals, APN can bind to specific transporters that influence the entry of amino acids (Fairweather et al, 2012). The digestive tract of some fishes contains high‐capacity peptide transporters (Karasov & Douglas, 2013; Small, 2022; Tian et al, 2015; Zheng et al, 2023). The further lowering of the APN activity at 72 h post‐feeding suggests a specific temporal modulation of the different steps involved in protein digestion in the intestine of juveniles of P. orbignyanus .…”

Integrative studies are lacking on the responses of digestive enzymes and energy reserves in conjunction with morphological traits at distinct postprandial times in marine estuarine‐dependent flatfishes of ecological and economic importance, such as Paralichthys orbignyanus. We determined total weight (TW), hepato‐somatic index (IH), activities of digestive enzymes in the intestine, and the concentration of energy reserves in the liver and the muscle at 0, 24, 72, and 360 h after feeding in juveniles of P. orbignyanus. Amylase activity decreased at 72 h (about 30%). Maltase, sucrose, and lipase activities reached peak at 24 h (67%, 600%, and 35%, respectively). Trypsin and aminopeptidase‐N activities at 24 and 72 h, respectively, were lower than those at t = 0 (53% and 30%). A peak increase in the concentration of glycogen and triglycerides in the liver (24 h) (86% and 89%, respectively) occurred. In muscle, glycogen and triglyceride concentrations were unchanged at 24 h and higher at 72 and 360 h (100% and 60%). No changes were found in TW, IH, free glucose in the liver and muscle, and protein in the liver. The protein concentration in the muscle sharply increased at 24 and 360 h after feeding (60%). The results indicate a distinct and specific response of central components of carbohydrate, lipid, and protein metabolism that could be adjustments at the biochemical level upon periods of irregular feeding and even of long‐term food deprivation inside coastal lagoons or estuaries. The distinct responses of digestive enzymes in the intestine and energy reserves in the liver and muscle suggest the differential modulation of tissue‐specific anabolic and catabolic pathways that would allow the maintenance of physical conditions.

Aquaculture in China has undergone significant evolution in recent decades, transitioning from traditional practices to a vital food production industry. Alongside the rapid growth of aquaculture in China, aquafeed production continues to expand swiftly. This review attempts to establish an overview of the history and achievements in aquaculture nutrition research and feed industry in China. The development of scientific concept and methodology, especially the advanced molecular biology technology guarantees the shift from traditional nutrition to molecular nutrition, and subsequently to precision nutrition in aquaculture nutrition research. This evolution has facilitated the formulation of effective strategies to enhance the growth, health and product quality of aquatic animals. The advancements of aquaculture nutrition research and feed industry have also been propelled by innovative research concepts rooted in principles such as the health and safety of aquatic animals, the quality of aquatic products, resource conservation and environmental friendliness, and the advancements in key processing technologies within the aquafeed industry. The future perspectives of the aquaculture nutrition research and feed industry in China are also proposed. The present work aims to provide a reference for promoting the development of aquaculture nutrition research and feed industry in China.
