Taxonomy has long been guided by natural scientists whose choices, methods, and values shape how biodiversity is named and used today. This study reconstructs the making of one regional fauna, the endemic freshwater fishes now recognized from the territory of the modern Greek state, focusing on the researchers who collected and described these species and how they shaped freshwater fish systematics. We review sources screened...

Nearly one‐third of extant freshwater fish species, which account for over 50% of global fish diversity, are at risk of extinction. Despite their crucial ecological and socioeconomic importance, the extinction of freshwater fishes remains under‐researched on a global scale. This is a comprehensive assessment of taxonomic, spatial, and temporal patterns of freshwater fish extinctions while identifying key extinction drivers and...

This contribution presents the first record of the invasive non-native red swamp crayfish Procambarus clarkii (Girard, 1852) in Greece and the Balkans. The crayfish was found during a fish monitoring expedition in the lower reaches of the Vosvozis River, near the city of Komotini, Thrace (northeastern Greece). The finding of P. clarkii in Greece expands the southernmost geographical range of the species in the Balkans and call...

A few studies have used historical inland fisheries data for defining reference points necessary for fisheries management. We developed a historical baseline of catches for inland fisheries of Greece during 1928–2019, with the interwar period (1928–1939), a period of intense political and socio‐economic turmoil, serving as a pre‐development reference period. The main harvested species were cyprinids, represented predominantly...

This study provides an annotated checklist of the freshwater fish species recorded in lentic ecosystems of Greece. Species distributional data were derived from an extensive review of published and unpublished sources and were evaluated for their consistency, adequacy and reliability. Overall, 650 freshwater lentic ecosystems (149 natural and 501 artificial) were investigated from which, 480 were fishless or fish data were una...

Aquaculture is related to environmental impacts locally and globally. The purpose of this study was to identify environmental hotspots in fish feeds of various granulations in seabass and meagre farming, by using Life Cycle Assessment (LCA), given that recent studies suggested fish feed as the predominant factor affecting environmental impacts in marine fish farming. This, in turn enabled a detailed comparison of the environme...

This paper is a collection of novel distributional records of 20 species belonging to 8 phyla (Chlorophyta, Rhodophyta, Cnidaria, Ctenophora, Annelida, Mollusca, Arthropoda and Chordata) from 11 Mediterranean countries, namely, Spain: an additional record of the Canary dentex Dentex canariensis is reported from Spain (Valencia), this is the northernmost record of this species in the Mediterranean; Algeria: the first documented...

The Hellenic freshwater aquaculture sector has been dominated by the alien rainbow trout since the early 1950s. This species actually represented 96.5% of the total inland production in 2007. Other groups of species accounted for minor production volumes and, apart from common carp, most of them are also of alien origin. Therefore, an absence of production diversification, the presence of alien species, which in some cases hav...

The diversity of ichthyofauna in Hellenic freshwaters is highlighted by the presence of 161 species. This actually represents 27.8% of the total fish species recorded in European freshwater, including both native and introduced species, suggesting that Greece represents a ‘hot spot’ for biodiversity. The introduction of alien species for restocking, the aquarium trade and aquaculture was responsible for the deliberate or accid...

Organic aquaculture has recently attracted attention from both researchers and industry. Organically produced aquatic products are increasingly available to consumers and, in particular, sea bass and sea bream from certified farms in Greece have been exported and also channelled to large retail markets in Greece since 2008. The current paper briefly reviews issues pertaining to global organic aquaculture and national organic a...
