About this Research Topic
Fish meal is the main protein and energy source of aquafeed because of its high protein content and digestibility, excellent and balanced nutrition composition. The booming aquaculture and limited fishing led to a shortage of fish meal. Hence, some animal proteins, plant proteins, lipids and carbohydrates were investigated to replace or economize the use of fish meal. Compared with fish meal, these substitutes do not fully meet the nutritional requirements of aquatic animals, may cause abnormal growth and diseases. To counteract the potential negative effects and improve physiology of aquatic animals, some functional feed additives, such as astaxanthin, bile acid, yeast extract, coenzyme Q10, chlorogenic acid, bile acid and algae extracts can be introduced into aquatic feed for taking advantage of their benefits for health. The purpose of this Research Topic is to evaluate the influence of such functional feed additives on growth, quality and physiological parameters in marine aquatic animals especially under the condition of low fish meal.
This Research Topic aims to study the effect of functional feed additives on quality and physiology state of marine aquatic animals especially under the condition of low fish meal. We welcome Original Research Articles, Review Articles and Mini-Reviews.
The following sub-topics are included in the Research Topic, but are not limited to:
• Feed additives application in low fish-meal diet
• Immune responses of marine aquatic animals affected by functional feed additives
• Metabolic changes of aquatic animals fed a low fish-meal diet with functional feed additives
• “Omics” of aquatic animals altered by functional feed additives
• Mechanism of functional additives in marine aquatic animals
• Fillet quality affected by functional feed additives
Keywords: Functional feed additives, Low fish meal, Marine aquatic animals, omics
