Microalgae are promising as prebiotics in aquaculture. Arthrospira maxima has potential nutritional value but is poorly studied. We assessed A. feed supplementation tilapia fry and evaluated its effect on growth performance gut microbiota. Fish were cultivated ponds under 0%, 5%, 10%, 15% inclusion treatments. Growth parameters biomass proximate analysis assessed. A meta-amplicon was performed the microbiota using DADA2 PICRUST2 for functional prediction. Among treatments, 5% group seemed to present no negative did not compromise quality of biomass. Microbial composition characterized by Cetobacterium, Pseudomonas Aeromonas genera, a predominance beneficial metabolic pathways. Microbiota fed with showed unique genera reported functions tilapia. The abundance pathogenic taxa significantly decreased possibly related valuable compounds maxima. microalgae supported stability microbiota, favoring commensal species.

Abstract For over 70 years, aquaculture practices have relied on the same methods for biosecurity, however epidemics remain a primary limitation of global yields with billions in revenue being lost every year due to disease. The intense nature fish and shellfish farming necessitates regular use synthetic chemicals as both preventive treatment measures, covering broodstocks hatching continuing through all stages rearing. This practice, however, results contamination rearing environments persistent xenobiotics. A specific drawback this foundational strategy biosecurity is highlighted current review: consistent water‐soluble polymer polyvinylpyrrolidone (PVP) across most, if not all, aquacultural livestock. PVP used intensively within it ubiquitous additive commercially available germicidal, prophylactic, therapeutic products applied control prevent disease outbreaks farms. As polymer, biodegradation‐resistant, has recently been described an emerging contaminant freshwater ecosystems. It well documented that other persistent, pollutants such microplastics, reduce fecundity, growth, significantly deplete immune function important aquatic species. Despite this, intentionally added soluble polymers, PVP, considered context productivity. review explores potential impact highlighting need adopt sustainable chemical practices, drawing inspiration from advancements nanotechnology human medicines address protocol deficiencies.

Despite all the technical-scientific knowledge about streptococcosis, high prevalence of bacterial infections caused by Streptococcus spp. in Nile tilapia farming implies frequent, often irresponsible, use antibiotics. The chemotherapy aquaculture environments remains an efficient practice treatment and disease prevention. Research have shown that emergence antimicrobial resistance (AMR) farmed fish is one main challenges faced aquaculture. It known emerging AMR can be transferred to clinically important strains from natural environment through horizontal gene transfer (HGT) affecting entire aquatic ecosystem. Maintaining health farms promotes sustainability production systems and, consequently, improves final quality farm products. Therefore, objective this review was provide information on prevention, control eradication diseases farms, how such management plays a fundamental role maintaining public ensuring adequate sanitary conditions for animals intended human consumption.
