Special Issue Information

Dear Colleagues,

The use of dietary enzymes in aquaculture is on the rise due to the volatility of supply and price of feed ingredients, environmental concerns, and the shift towards closed farming systems. The leading dietary enzymes in aquafeed is phytase followed by protease and carbohydrases. The use of dietary protease in aquafeed is particularly important as proteins are the major cost component of any aquafeed. They are gaining importance worldwide as an important tool to optimize formulation costs. Besides cost-optimization and wastes management, specific proteases also play a role in immune systems and modulate the gut microbiota of the cultured animals.

The special issue will deal with types and composition of commercially available dietary protease, their substrate preference, issues in the application, and effects on growth, nutrient digestibility, immunity, gut morphology, disease resistance, and gut microbiota of farmed aquatic animals and on nutritional wastes management.

We expect highly relevant articles on the above-mentioned topics including review articles.
