Red mullet () is a commercially relevant fish species, yet epidemiological data on anisakid nematode infestation in are scarce. To fill this gap, we report the occurrence of larvae in red mullet in the Ligurian Sea (western Mediterranean). This survey was performed between 2018 and 2020 on fresh specimens of (n = 838) from two commercial fishing areas (Imperia, n = 190; Savona, n = 648) in the Ligurian Sea. Larvae morphologically identified as spp. (n = 544) were characterized using PCR-RFLP as . The overall prevalence of was 24.46%; the prevalence at each sampling site was 6.32% for Imperia and 29.78% for Savona. Furthermore, 3300 larvae of spp. were detected in the visceral organs of fish coinfected with , showing that coinfection with two parasitic species is not rare. This study provides a timely update on the prevalence of ascaridoid nematodes in red mullet of the Ligurian Sea, an important commercial fishing area in the Mediterranean.

Sorting grids to exclude the juveniles of species targeted by bottom trawl fisheries from the catch are among the most promising solutions to reduce discards. We tested a two-sections Juveniles' Sorting Grid (JSG) in a Mediterranean fisheries restricted area. First, we provided information on the vitality of individuals escaping from the JSG bars during towing, by analysing underwater footage.

Nucleoredoxin (NXN) is a prominent oxidoreductase enzyme, classified under the thioredoxin family, and plays a pivotal role in regulating cellular redox homeostasis. Although the functional characterization of NXN has been extensively studied in mammals, its role in fish remains relatively unexplored. In this study, the NXN gene from Planiliza haematocheilus (PhNXN) was molecularly and functionally characterized using in silico tools, expression analyses, and in vitro assays.

The common seahorse, Hippocampus kuda, is widely distributed throughout the Indo-Pacific region, occurring from East Africa to Hawaii, where it typically inhabits diverse ecosystems such as estuaries, lagoons, coastal zones, and seagrass beds. Despite its extensive geographic range, reports of its occurrence in the Red Sea remains limited, primarily restricted to the northern region of the Red Sea. Here, we report a new distributional record of H.

The vector effects of microplastics (MPs) in natural marine environments and their contribution to polycyclic aromatic hydrocarbon (PAH) bioaccumulation in fish are still unknown. This study, therefore, aimed to evaluate the effects of MPs on carrying PAHs under conditions close to the actual marine environments. The PAH content sorbed onto MPs from seawater positively correlated with the octanol/water partition coefficient (log K) in both polyethylene and polystyrene MPs.
