Aquaculture is the fastest-growing sector of food production worldwide, yet the industry continues to grapple with challenges posed by bacterial diseases. Traditionally, antibiotics have served as the primary defense against bacterial outbreaks. However, the excessive use of antibiotics has resulted in significant challenges, including the development of antimicrobial resistance, environmental pollution, and concerns regarding food safety. As a result, there is a pivotal shift towards sustainable practices. One such approach capturing interest is the use of natural extracts sourced from plants, algae, fungi, and marine organisms. These bioactive compounds hold promise due to their diverse mechanisms of action, which encompass direct antimicrobial effects, immunostimulation, and microbiota modulation.
This Research Topic aims to delve into the potential of natural extracts as sustainable antibacterial agents for managing bacterial diseases in aquaculture settings. Despite preliminary findings that demonstrate promise, critical aspects such as the precise efficacy, mechanisms of action, and practical applications of these natural compounds remain insufficiently explored. The primary objective of this research is to enhance the identification, characterization, and application of natural extracts with antibacterial properties, specifically targeting key aquaculture pathogens.
To gather further insights into these promising alternatives, the scope of this research encompasses a range of themes. We welcome articles addressing, but not limited to, the following themes: • Effects of natural extracts on pathogen load, host immune responses, and fish health • Safety, stability, and delivery methods of these compounds, particularly through aquafeeds • Isolation and identification of bioactive compounds from various sources • In vitro and in vivo assessments of antibacterial efficacy and mechanisms of action • The impact on fish microbiota and the formulation strategies for practical applications
Moreover, studies utilizing omics technologies, bioinformatics, or biotechnological approaches to elucidate molecular interactions or optimize the utilization of extracts are encouraged. Research contributions should demonstrate a clear relevance to promoting sustainable aquaculture.
