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 ...

Age and growth of round sardinella (Sardinella aurita) in the northeastern Mediterranean

Scientia Marina, 2005
The round sardinella, Sardinella aurita Valenciennes, 1847, was sampled monthly from commercial purse-seine vessels in Kavala Gulf (northern Aegean Sea, Greece) for two complete year cycles (September 2000-August 2002).

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.

Variability of key biological parameters of round sardinella Sardinella aurita and the effects of environmental changes [PDF]

Journal of Fish Biology, 2019
We examined growth rates and reproductive characteristics of Sardinella aurita off Senegal and other coastal areas over a 20 year period (1995–2014) to determine how they relate to variations in environmental characteristics of coastal waters. Based on fish length‐frequency data and a coastal upwelling index, we found that S.

Reproductive Biology of Round Sardinella (Sardinella Aurita) (Valenciennes, 1847) in Senegalese Coastal Waters

Journal of Biology and Life Science, 2018
In this study, a total of 1068 specimens Sardinella aurita of which 553 females and 515 males were examined. The objectif of this study was to determine the reproductive parameters of Sardinella aurita. The sex ratio was significantly in favor of females (55%). The size at first sexual maturity was estimated at 18.9 cm for females and 18.0 cm for males.

Stock assessment of round sardinella (Sardinella aurita) caught along the coast of Senegal [PDF]

, 2020
The LBB and CMSY/BMS methods were used to evaluate the state of the stock of round sardinella (Sardinella aurita) based on national data from the Exclusive Economic Zone (EEZ) of Senegal. However, this migratory stock is shared between Morocco, Mauritania, Senegal, and The Gambia.

Global Marine Fishery Stock Productivity Under Climate Change. [PDF]

Glob Chang Biol
In this uniquely extensive global analysis on the productivity of commercial fishery stocks, a common factor was the existence of pronounced heterogeneity, as documented for 710 stocks in the undertaken hindcast over the last decades. Importantly, both winners and losers appear under on‐going climate change, and then seemingly are equally present ...
