“…Some of these invasive species now play a conspicuous role in Mediterranean food webs, becoming the dominant species, such as the green tropical alga Caulerpa taxifolia along the French and Italian Rivieras (Meinesz and Hesse 1991;Boudouresque and Verlaque 2002). This dominance has caused in turn changes in species abundance and trophic links in the food web [for example, see Lemee and others (1996) and Ceccherelli (1997)]. In the Eastern Mediterranean, nonnative species have arrived from the Red Sea via the Suez Canal for more than 100 years (Por 1978).…”

The understanding of the taxonomic composition of Mediterranean subtidal rocky-shore food webs is extraordinary; the information on trophic links and food-web structure is, however, still meager. An initial description of the rocky-bottom food web of the Medes Islands off the Catalan coast includes a minimum of 1350 species organized in five trophic levels. A minimum of 151 trophic links have been identified for 37 broad trophic/taxonomic categories (including humans), although estimates of the total number of links at the species level may be on the order of thousands for fishes alone. Mediterranean food webs are dynamic, their topology and structure varying along seasonal and environmental gradients. Fishing has been for thousands of years the single major factor provoking changes in the structure of these Mediterranean food webs. Ecologically extinct megafauna (monk seal, loggerhead turtle, sharks) accounted for 24% of the identified trophic interactions. The removal of these large consumers had undescribed ecological consequences. Improved understanding of present and past Mediterranean food webs will improve understanding of the effects of human activities and help us preserve and restore these food webs.

“…The aquarium trade has been linked to over 150 species invasions in natural ecosystems around the world (Fuller, 2003;Siguan, 2003;Padilla & Williams, 2004). Severe ecological impacts are evident on native species (Ceccherelli & Cinelli, 1997), whereas the extinction of native fish populations by predation and/or resource competition has also been documented (Pimentel, 2010). However, the aquarium trade has received lesser attention from environmentalists, conservationists, ecologists, and policy makers as opposed to the attention given to the trade of terrestrial endangered species (Naylor et al, 2001;Chapman et al, 2003;Padilla & Williams, 2004).…”

The aquarium trade has been recognized as an important pathway for the introduction of invasive species around the world. This study investigates the availability of ornamental fish species in ten large-size, centrally positioned aquarium stores that control a large share of imports and the Hellenic market chain, and aims to provide a provisional checklist on the aquarium fish trade in Greece. For each recorded species, additional data concerning various aspects (e.g. natural environment, native range, established as aliens, conservation status and threats to humans) were collected from Fishbase, IUCN red list and the scientific literature. Overall, 326 fish species belonging to 64 families were reported according to the store labels. The majority of the species recorded were freshwater (66%), originating mainly from South America and Asia, while most of the marine species (26%) had primarily an Indo-Pacific native distribution. Among the freshwater fishes, Cichlidae and Cyprinidae were the dominant families with 64 and 27 species, respectively, while the family Acanthuridae dominated within the marine fishes with ten species. The vast majority of both freshwater and marine species (>90%) were tropical. Concerning the presence of alien species, 62 ornamental species have been established outside their natural range, with 22 of them positively confirmed as aliens in the European waters. Moreover, 25 species were listed in the critically endangered (CR), endangered (EN) and vulnerable (VU) categories of the IUCN red list. Even more surprisingly, for 192 species recorded, data were missing to assign their conservation status or had not been assessed at all. Finally, the majority of the species (84%) were harmless to humans. However, 35 species (11%) were recognised as potentially harmful (i.e. venomous, ciguatera poisoning, traumatogenic) and two were found to be poisonous if consumed. In conclusion, the aquarium fish sector in Greece is practically uncontrolled given the presence of: a) threatened species, b) species potentially harmful to humans and c) species capable of establishing non-indigenous populations, if released into the wild.

“…cylindracea (Sonder) Verlaque, Huisman et Boudouresque. These two species rapidly became widespread after their introduction into the Mediterranean Sea and affected both the indigenous seagrass ecosystems and other species assemblages (De Vill è le and Verlaque 1995, Ceccherelli and Cinelli 1997, Piazzi et al 2001, Ceccherelli and Campo 2002. The more notorious of the two is C. taxifolia , which became a dominant feature of the northwestern Mediterranean coastline (Meinesz et al 2001 ) after its apparently accidental release from the public aquarium in Monaco, where it was on display Hesse 1991 , Jousson et al 1998 ).…”
