New Progresses of Fish Meal Replacement in Aquatic Animals

Fish-meal (FM) is the most important dietary protein source for shrimp and carnivorous fish. Due to the global expansion of aquaculture, the limited production of FM has become a restrictive factor for the speedy and sustainable development of aquaculture. During the last decades, many kinds of plant protein sources and animal protein sources are successfully applied to replace FM in aquaculture. Recent years, new protein sources such as insect protein, bacterial protein, algae protein are emerging as excellent alternatives to FM. Besides, the rapidly developing new technologies such as omics approaches allow us to better understand the complex process of FM replacement.

This Research Topic aims to developing new alternatives to fish meal and expand our understanding of fish meal replacement. Related studies in the format of Original Research, Reviews and Mini-Reviews are welcomed.

The following subtopics are covered, but not limited to
- Application of new protein sources and lipid sources in aquatic feeds
- Metabolic changes of aquatic animals fed low a fish-meal diet
- “Omics” of aquatic animals altered by dietary protein sources
- Immune responses of aquatic animals affected by low dietary fish-meal
- Feed additives application in low fish-meal diet
- Fish meal and fish oil replacement based on genetic breeding
- Fillet quality affected by dietary proteins sources and lipid sources
