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

Health risk assessment of organochlorine pesticide residues in edible tissue of seafood [PDF]

Frontiers in Veterinary Science, 2022
Fish is one of the most valuable foods with high-quality animal protein. However, aquaculture, or ingesting contaminated food, allows organochlorine pesticides (OCPs) to enter the fish's body, and therefore, it negatively impacted public health.

The Role of Dietary Fatty Acids in Modulating Blue Crab (Callinectes sapidus) Physiology, Reproduction, and Quality Traits in Captivity [PDF]

Animals
The invasive blue crab is challenging the Mediterranean basin, progressively declining local populations. This reflects a lower prey availability and suitability of dietary nutrients (mainly n-3 polyunsaturated fatty acids, PUFA). The present study aimed

G lugea sp. infecting Sardinella aurita in Algeria. [PDF]

J Parasit Dis, 2022
Parasitological examination of the commercially important pelagic fish Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Eastern coast of Algeria revealed xenomas in the peritoneal cavity, suggesting a microsporidian infection. The prevalence of the disease was approximately 30% on average, higher in smaller individuals and showing significant ...

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.

Cities at Sea: Coastal Urbanization Generates Local Biodiversity Hotspots but Homogenizes Marine Fish Communities Regionally. [PDF]

Glob Chang Biol
We investigated whether coastal urbanization drives marine communities toward greater similarity, a process well‐documented as urban biotic homogenization in terrestrial and freshwater ecosystems but largely unexplored in the marine realm. From seawater environmental DNA samples collected along the French Mediterranean coastline targeting fish ...
