In this study, a pair of matured specimens of gilthead sea bream (Sparus aurata Linnaeus, 1758) were collected at a depth of approximately 20 m near Keelung Port, northern Taiwan (25°11'32″N, 121°47'8″E), on November 23, 2024. The specimens were identified and confirmed as S. aurata through both morphological and molecular analyses. This marks the first invasion recorded of the gilthead sea bream in the northwestern Pacific Ocean, representing a significant range expansion from its native Atlantic-Mediterranean habitat. The likely cause of this invasion is attributed to escapes from the aquaculture industry. The potential ecological impacts of this potential harmful invasive species on the marine ecosystem warrant further investigation, and a well monitoring on the alien aquaculture species is also recommend.

Host-pathogen interactions and the design of vaccines for aquaculture fish viruses are challenging and call for innovative approaches. This study explores the potential of adenoviral (Ad) vectors Ad5 and chimeric Ad5/40 as gene delivery tools for fish brain cells susceptible to neurotropic viruses. For this purpose, European sea bass () DLB-1 and gilthead seabream () SaB-1 brain cell lines were infected with Ad5 or Ad5/40 vectors expressing GFP, and we evaluated their capacity for infection by fluorescence microscopy and flow cytometry, as well as their antiviral innate immune response by the transcription of gene markers ( and ).

The aim of the study was to investigate the potential preventive use of short-chain fatty acids (SCFAs) to modulate inflammatory responses in gilthead seabream (Sparus aurata) skin. Initially, in vitro experiments were conducted to evaluate the effects of various concentrations of butyric acid, acetic acid and propionic acid, as well as their combination, on the cytotoxicity and cell viability of three different cell lines. The results determined the safe concentration of SCFAs, which was then used for an in vivo study.

Hermetia illucens larvae oil (HIO) is a promising new ingredient that can potentially be an alternative lipid source in aquafeeds. To assess its viability in gilthead seabream juvenile diets, a 10-week feeding trial was performed, and the effects on antioxidant, immune, and inflammatory responses were evaluated. Four diets were formulated to include HIO at increasing levels: 0, 4, 7.

Microplastics (MPs) are a threat of growing concern for living organisms as they exist in all ecosystems. The bidirectional communication between the gut, its microbiota, and the liver, has been conceptualized as gut-liver axis and may be influenced by environmental factors. MPs can cause intestinal and hepatic injuries, but there is still limited research exploring their impact on gut-liver axis.
