Food fraud is still a recurrent practice throughout food supply chains. In the case of seafood, misidentification of species and products repackaging constitute the most common frauds. Therefore, the development of appropriate analytical approaches to be used against food fraud is necessary. The present study goal is to explore for the first time, the possibility to differentiate between Sparus aurata from two different mariculture farms located in Madeira Island (Caniçal and Ribeira Brava), using the mass fingerprint of fish mucus obtained from MALDI-TOF MS and analyzed using Mass-UP software for multivariate statistical analysis and biomarker identification. It was possible to establish, from the mucus protein fraction, a set of potential biomarkers for each location in a total of 35 peaks, being 17 peaks specific to Caniçal located farm and 18 to Ribeira Brava. The proposed analytical approach revealed a useful strategy providing accurate and fast results for fish geographical origin discrimination.

The Mediterranean Sea is home to a wide variety of fish species that exhibit carnivorous behavior, particularly during the juvenile to pre-adult stages. This study aimed to compare the tongue morphology of four Mediterranean carnivorous fish species: the dusky grouper fish (Epinephelus marginatus), John Dory fish (Zeus faber), squirrelfish (Holocentrus spp.), and red lionfish (Pterois volitans).

Objective: Renibacterium salmoninarum, the causative agent of bacterial kidney disease, poses a major threat to both wild and aquaculture salmonid populations. Traditional detection methods typically involve lethal sampling to collect kidney tissues but are often impractical for species of conservation concern. This study evaluates nonlethal sampling techniques for detecting R.

During the long course of evolution, fish have developed complex skin structures to adapt to the dynamic aquatic environment. These skin features not only reflect optimal adaptation to the aquatic environment but also play a key role in effectively reducing fluid drag and improving swimming efficiency, to reveal the intrinsic connection between the complex skin structure of fish and drag reduction performance and to provide new design ideas for the drag reduction surface of underwater vehicles. Based on the different drag reduction characteristics of fish skin structures, this paper divides existing biomimetic drag reduction technologies into three categories: riblet drag reduction, flexible drag reduction, and composite drag reduction.

This study aimed to determine the effects of dietary red ginseng, Panax ginseng powder (RGP), on the growth performance, immunity, antioxidant system, and disease resistance of the rainbow trout, Oncorhynchus mykiss. Eight experimental groups were established, including a control group and seven groups fed varying levels of ginseng powder (5 to 35 g/kg) over 60 days, followed by a challenge with Streptococcus iniae. The results indicated that ginseng supplementation significantly enhanced growth parameters (P < 0.

High-temperature (HT) is a critical influencing factor in shrimp aquaculture and serves as a key trigger for frequent disease outbreaks in shrimp. As a core organ for digestion, absorption and immune defense, the intestine's functional homeostasis is the key foundation for shrimp health. Therefore, in this study, the shrimp Litopenaeus vannamei were continuously exposed to HT stress at 33 °C for 7 days, after which the changes in intestinal functional homeostasis were investigated based on the mucosal integrity, immune signaling, and microbial community.
