Objectives
The Journal of Fish Nutrition aims to advance scientific knowledge and practical applications in fish nutrition and feeding. The journal provides a platform for disseminating research that improves understanding of nutritional requirements, feed utilization, and the relationships between nutrition, growth, health, and product quality. It also promotes the development of effective, economically viable, and environmentally responsible feeding strategies, including the use of natural food, live feeds, and formulated feeds, to support sustainable aquaculture.
Scope
The journal welcomes contributions addressing fundamental and applied aspects of fish nutrition in freshwater, brackishwater, and marine species. Its scope includes:
-
Nutritional requirements: Requirements for proteins, amino acids, lipids, fatty acids, carbohydrates, vitamins, minerals, and energy across species and life stages.
-
Feed ingredients and alternative resources: Evaluation of conventional and alternative ingredients, including plant materials, animal by-products, insects, algae, microbial biomass, biofloc, and fermented ingredients.
-
Natural food and live feeds: Nutritional quality, cultivation, enrichment, and utilization of microalgae and other phytoplankton, rotifers, Artemia, copepods, cladocerans, worms, and other natural food organisms. Topics include their contributions to nutrient intake, growth, survival, and larval and juvenile development, as well as co-feeding and weaning strategies involving formulated feeds.
-
Feed formulation and processing: Diet formulation, feed manufacturing, fermentation, processing technologies, feed quality, storage stability, and physical properties.
-
Digestion and nutrient metabolism: Feed intake, digestibility, nutrient absorption, metabolic regulation, nutrient retention, and nutrient utilization.
-
Feeding practices and management: Feeding rates, frequency, schedules, feeding behavior, precision feeding, and feeding strategies under different aquaculture systems.
-
Functional feeds and nutritional health: Feed additives, probiotics, prebiotics, enzymes, phytogenic compounds, and other dietary interventions affecting physiological performance, antioxidant status, immune responses, and disease resistance.
-
Nutrition under environmental stress: Nutritional responses and dietary strategies associated with temperature, salinity, hypoxia, pollutants, and other environmental stressors.
-
Nutrition and product quality: Effects of diets on body composition, fillet quality, nutritional value, and the safety of fish products.
-
Sustainable feeds and environmental impacts: Feed resource efficiency, circular use of materials, nutrient losses, waste reduction, and the economic and environmental implications of feeding practices.
Studies involving other cultured aquatic animals may also be considered when they provide clear insights relevant to fish nutrition or aquafeed development. Manuscripts must establish a direct connection to nutrition, feed, or feeding. Studies focused solely on general aquaculture production, water quality, disease, or natural food cultivation without a nutritional or feeding component fall outside the journal’s scope.
