On the Epidemiology of Xenoma-Forming Microsporidia in Wild Caught Fish from Macaronesia (FAO34) [PDF]

Veterinary Sciences
Microsporidia are a group of obligate intracellular parasites with a broad host range. These parasites can cause mild to severe harm to their hosts, making them important targets for research. However, studies on common wild-caught fish from the Atlantic

Oxytetracycline as an otolith chemical marker in Atlantic bluefin tuna (Thunnus thynnus): Technical feasibility in culture. [PDF]

J Fish Biol
Abstract Reliable discrimination between wild and cultured fish is essential for traceability in aquaculture. This study reports the first successful application of intramuscular oxytetracycline (OTC) injection for otolith marking in juveniles of Atlantic bluefin tuna (Thunnus thynnus).

Studying of <i>Trachurus trachurus</i> (Linnaeus, 1758) Population Reproductive Dynamics in the Eastern Moroccan Mediterranean. [PDF]

Ecol Evol
Horse mackerel (Trachurus trachurus) populations along the eastern Moroccan Mediterranean coast were studied over 12 months using 390 specimens to assess reproductive ecology. The species showed two spawning periods—late winter to early spring and summer—and exhibited fractional spawning, with males being more predominant.

Genomics Detects Japanese and Pacific Sardine (<i>Sardinops</i> spp.) Hybrids in the Northeast Pacific Ocean. [PDF]

Ecol Evol
Using a newly developed nuclear Genotyping‐in‐Thousands‐by‐sequencing (GT‐seq) panel that unambiguously differentiates Japanese and Pacific Sardine, we report the first detection of Sardinops spp. hybrids. Previous genomic analyses of Pacific Sardine in the Northeast Pacific detected the presence of Japanese Sardine along the west coast of North ...

Feeding ecology and trophic interactions of the narrow-barred Spanish Mackerel (Scomberomorus commerson) in the Central Taiwan Strait [PDF]

PeerJ
Understanding the foraging ecology of marine predators is essential for ecosystem-based fisheries management. This study examined the diet of the narrow-barred Spanish mackerel (Scomberomorus commerson) in the Central Taiwan Strait using stomach content ...

Molecular Characterization of Cryptosporidium spp. in Cultivated and Wild Marine Fishes from Western Mediterranean with the First Detection of Zoonotic Cryptosporidium ubiquitum [PDF]

Animals, 2022
Fish not only harbor host-specific species/genotypes of Cryptosporidium, but also species like zoonotic C. parvum or anthroponotic C. hominis, which can pose a risk for fish consumers. This study aims to investigate fish cryptosporidiosis in an important

Estimation of selectivity parameters for target and bycatch fishes of the trammel net fisheries in the northern Aegean Sea (eastern Mediterranean Sea) [PDF]

Acta Ichthyologica et Piscatoria, 2023
The size selectivity of trammel nets was investigated in the northern Aegean Sea using 10 different inner-panel mesh sizes ranging from 16 to 70 mm nominal mesh size (bar length).
