Laurel oil improves growth and immunity in Nile tilapia under cold stress

This study investigated how laurel essential oil (Laurus nobilis) can help Nile tilapia cope with cold stress. The fish were fed diets containing different doses of the oil, and the 1.5 g/kg dose stood out, resulting in better growth, enhanced immunity, and reduced stress levels. In addition, there was an improvement in intestinal and liver health, an increase in antioxidant activity, and a decrease in inflammation. Overall, bay leaf oil shows strong potential as a natural supplement to support fish health in adverse conditions.

Tracking feed residues in aquaculture effluents

An intelligent imaging system captures images of the water to detect and count uneaten feed. By reducing glare and reflections, clearer images are obtained, making it easier to determine how much feed is being wasted. This allows fish farmers to adjust feeding in real time, saving money and reducing environmental impact.

Seaweed extracts for colorectal cancer caused by fructose-rich diets

Ecklonia kurome, a seaweed used in Traditional Chinese Medicine, together with its main components, such as fucoidan and brown seaweed polyphenols, has been shown to reduce colorectal cancer associated with colitis induced by a high fructose content. This effect is demonstrated by a significant decrease in tumor growth after treatment. This discovery supports a new treatment approach for patients with colorectal cancer associated with colitis, especially those affected by diets rich in fructose.

Vaccines against infectious salmon anemia and their use

This study provides compositions, nucleic acids, and proteins developed to help prevent and treat infectious salmon anemia (ISA) in bony fish. One version is a vaccine that uses nucleic acids, such as mRNA, that encode the main ISA antigens or their variants. These are provided with a carrier to trigger an immune response and protect the fish.
