Researchers tested whether a dietary mix of rosemary and cinnamon could protect Nile tilapia from the harmful effects of lead exposure. Fish exposed to lead showed reduced growth, suppressed immunity, increased oxidative stress, and DNA damage, but those fed the herbal supplement showed significant improvements across all measures. The study suggests that rosemary and cinnamon supplementation may help mitigate heavy metal toxicity in farmed fish.

Dietary Curcumin Promotes Gilthead Seabream Larvae Digestive Capacity and Modulates Oxidative Status
Adding curcumin to the diet of gilthead seabream larvae improved their digestive capacity and antioxidant status. The research explores natural dietary supplements for improving fish health in aquaculture, which is relevant as farmed seafood is a source of microplastic exposure for humans.
Antioxidant and Microbiota Characteristics Across Different Mucosal Sites of Rice Flower Carp (Procypris merus)
Researchers characterized antioxidant activity and microbiota composition across gill, skin, and intestinal mucosal sites in rice flower carp (Procypris merus), finding distinct profiles at each site with gill tissue showing the highest catalase activity and oxidative stress markers. The study provides baseline data on mucosal immune and microbial differences across body sites in this underexplored fish species.
Aquaculture Water Quality Improvement by Mixed Bacillus and Its Effects on Microbial Community Structure
This study tested two combinations of beneficial Bacillus bacteria in crucian carp aquaculture tanks, finding they improved water quality by reducing nitrogen and phosphorus compounds and shifted microbial community structure toward more beneficial species. Probiotic bacterial treatments offer a sustainable alternative to antibiotics for maintaining aquaculture water quality.
Protective Effects of Curcumin and/or Ginger Supplementation against Oreochromis niloticus Oxidative Stress Induced by Ultraviolet-A Radiation
Researchers found that dietary supplementation with curcumin and/or ginger significantly protected Nile tilapia from oxidative stress induced by ultraviolet-A radiation, improving antioxidant enzyme activity and reducing DNA fragmentation and lipid peroxidation. The findings suggest these natural compounds can serve as effective antioxidant feed additives in aquaculture.
Microbial Resistance to Antibiotics and Biofilm Formation of Bacterial Isolates from Different Carp Species and Risk Assessment for Public Health
Researchers examined antibiotic resistance and biofilm formation in bacteria isolated from common, silver, and grass carp species. While antibiotic residues were detected in fish samples, the estimated daily intake was well below acceptable limits, and the study suggests that fresh fish consumption remains safe from this perspective.
