Summary: This study demonstrates that juvenile sea bass exposed to oil spills exhibit transient behavioral impairments, with a dose-response relationship observed. Recovery capacities were seen within the first 10 days post-exposure, although fish may require more time for full recovery. The alterations in behavior may be attributed to neurosensory or physiological defects caused by oil exposure, leading to sedative behaviors resembling anesthesia.

Summary: The present study aimed to determine the effectiveness of genetic selection for growth in European sea bass in response to a challenge with an alternative diet. The results showed that European sea bass selected for 7 generations performed better in terms of growth, with decreased fat content and increased nutritional value of flesh. The dietary treatment had little effect on fish growth performance, indicating successful replacement of fishmeal and fish oil. Therefore, multi-trait genetic selection can improve the ability of European sea bass to adapt to alternative feeds with low fishmeal and fish oil.

Summary: A mycological examination of 250 whiteleg shrimp clinically infected with black gill melanization revealed that Fusarium solani was the dominant causative agent, with an incidence rate of 66% compared to 34% for F. oxysporum. In vitro testing showed that O. vulgare and orange peel essential oils had a strong antifungal effect against F. solani, surpassing the commercial antimicrobial Biotronic (R) Top3. In vivo experiments demonstrated that dietary supplementation of O. vulgare and orange peel essential oils alleviated immune suppression and histopathological effects caused by F. solani infection in L. vannamei.

Summary: Clay minerals, like bentonite (BNT), have gained attention as non-nutritive additives in aquaculture for maintaining water quality and improving productivity. The study found that BNT-treated groups had significantly reduced ammonia content and improved fish performance. Furthermore, the BNT-treated groups showed improved blood biochemistry, digestive enzymes, liver and kidney function, as well as immune and antioxidant parameters. Histological analysis revealed healthier organs in the BNT-treated groups, except for hepatic vacuolations in the liver. Pancreatic sections were unaffected. Therefore, BNT at a concentration of 3 g/L is recommended for marine aquaculture to reduce ammonia and enhance fish growth, health, and immunity.

Summary: This study evaluated the multidrug resistance and multivirulence profiles of Staphylococcus aureus strains isolated from cows with mastitis. All isolates were found to be biofilm-producing methicillin-resistant S. aureus (MRSA) strains. The tested essential oils (EOs) demonstrated antimicrobial and antibiofilm activities that matched with the phenotypic evaluation and molecular docking studies. Synergistic interactions between the investigated EOs and methicillin or vancomycin were detected. Additionally, 13 isolates showed a change in antimicrobial resistance patterns to sensitive phenotypes after treatment with any of the investigated EOs. Combining the EOs with available antimicrobial drugs can prevent treatment failure of bovine mastitis caused by resistant S. aureus.
