| The aim of the study is to determine how seawater is used in Ré island marine ponds (Charente-Maritime, France). Thus, we assessed the ecosystem functioning, estimated its historical evolution and determined the most suitable ways to improve current management processes. The knowledge of seawater management is essential to ensure wetland future and meet the numerous interests of wetland stakeholders, especially in term of seawater sharing. Consequently, it is necessary to consider the Ré island marine embanked wetland through its natural as well as human characteristics. Our work followed two research axes. First, a survey and a description of wetland activities were realized through their management types and their water use features, knowing that human... |

| La présente étude sédimentaire revêt trois intérêts majeurs. D’abord, elle introduit différentes thématiques sédimentologiques reposant sur des techniques éprouvées (microgranulométrie, rhéométrie, détermination de la matière organique particulaire par CHN) qui, combinées entre elles, constituent une démarche originale conduisant préalablement à la caractérisation des fonds sédimentaires subtidaux des pertuis charentais jusque-là peu connus. Ensuite, elle s’inscrit dans une démarche multidisciplinaire, qui devrait permettre un certain nombre de corrélations avec les trois autres approches (halieutique, benthique, écotoxicologique). Cette dimension à différentes facettes disciplinaires pourra faire mieux comprendre la réactivité du sédiment à l’action... |

| The main objectives of this investigation were to test the effects of (i) the presence of periphyton substrates, (ii) rearing density and (iii) supplemental feeding with dry feed on the growth and production of golden mullet (Liza aurata) juveniles. Twenty-six 1 m(2)-cages were installed in a French marine pond from April till June 2008. Mullets were stocked in cages with or without substrate at a density of 0, 20,40 or 60 individuals per cage. Each treatment was carried out in triplicate. In addition, 20 fish were put in three tanks and fed ad libitum with dry feed. The results showed that (i) although mullets were seen to graze on periphyton substrates, their presence did not affect,mullet growth and production. In future studies, meshed substrates could... |
