Abstract Methionine (Met) is an important building block and metabolite for protein biosynthesis. However, the mechanism behind its absorption in the fish gut has not been elucidated. Here, we describe the fundamental properties of Met transport along trout gut at µmol/L and mmol/L concentration. Both electrogenic and unidirectional DL-[14C]Met flux were employed to characterize Met transpo ...

ABSTRACT Methionine is a key factor in modulating the cellular availability of the main biological methyl donor S-adenosylmethionine (SAM), which is required for all biological methylation reactions including DNA and histone methylation. As such, it represents a potential critical factor in nutritional programming. Here, we investigated whether early methionine restriction at first feeding could ...

ABSTRACT This study aimed to assess macronutrient-specific energy utilisation efficiency (i.e., protein, lipid and carbohydrate) for growth in common carp (an omnivorous species) and barramundi (a carnivorous species) and to assess if species-specific differences exist in energy efficiency of digestible protein (dCP), digestible fat (dFat) and digestible carbohydrates (dCarb). This was achieved b ...

Abstract A study was conducted to evaluate the effects of lowering dietary fishmeal (FM) and crude protein (CP) levels, while maintaining essential amino acid levels, on growth performance, body composition, muscle metabolic gene expression, and chronic stress response of rainbow trout, Oncorhynchus mykiss, with and without handling stress. Eight experimental diets (isocaloric) with a 4 × 2 ...

Conclusion Response of juvenile Nile tilapia to 3 levels of dietary Met (0.77 %, 0.95 % and 1.15 %) and 4 levels of dietary Lys (1.2 %, 1.6 %, 2.0 %, and 2.4 %) were evaluated in 3x4 factorial design over a 56-d feeding trial. Data showed main effects of both Met and Lys as well as their interaction (Lys x Met) effects on the performance of tilapia. Looking at the interaction effects, it was e ...

Key Information Grass carp production is the largest finfish aquaculture industry in China, with an increasing volume of commercial feed production. This justifies the need to improve our understanding of the dietary nutrient requirements of this species in order to produce them more efficiently. Available data on the amino acid requirements of grass carp show high variability and do not cover ...

Summary Shrimp performed equally well on diets containing 16% fish meal (FM) or 8% fish meal supplemented with AQUAVI® Met-Met (0.03-0.10%). Retention efficiencies of protein and amino acids improved significantly with the supplementation of AQUAVI® Met-Met in low FM diets. In addition, shrimp fed the low FM diet supplemented with 0.1% AQUAVI® Met-Met showed better retention effici ...
