Chapitre 4 : Impact of vegetation structure dynamics and usage on the nursery function of West European tidal salt-marshes. 4.5. Composition of the fish population of the Mont Saint-Michel bay : The spring and autumn surveys in Mont Saint-Michel bay captured 10 316 fish with a total biomass of 14 kg. Fifteen species belonging 13 genera were recorded. The same ecological guilds that were defined above were present. With the exception of the Greater weever all the species captured also occurred in the Aiguillon bay. On the other hand, 7 species were not captured in Mont Saint-Michel bay during this survey (Transparent goby, Silverside, Pilchard, Common sole, Nilsson’s pipefish, European anchovy and Gilt head). The latter two species have not been recorded in Mont Saint-Michel bay (this is situated outside the distribution range of the Gilt head, and the European anchovy prefers to colonise saline waters rather than salt marshes). The great majority of the fish captured belonged to juvenile stages, and in particular to the young-of-the-year group (European sprat, Clupeidae yoy, Seabass, Flounder, Greater weever). Mullets accounted for nearly 91% of the total biomass (Thinlip mullet %B=74.32% and Golden grey mullet %B=16.11%). The mullet species and the Common goby were the most frequently encountered species (%F>75%). Next came the European sprat (%F=71.4%), Clupeidae yoy and Seabass with a frequency of occurrence of 57.1% (Table 2). The numbers were largely dominated by the Sand goby (%N=45.61% i.e. 4705 fish) and the Thinlip mullet with 3425 individuals (Thinlip mullet %N=33.20%). The structure of the colonising guilds was also investigated in the species present in Mont Saint-Michel bay (not presented). 133
