  abstract = {{E}xtracellular enzymatic activities constitute the first and limiting step of the whole process of organic matter ({OM}) cycling in aquatic ecosystems. {T}his study aims to identify the factors controlling prokaryotes ability to hydrolyse {OM} in an {I}ndo-{P}acific tropical mangrove ecosystem ({C}an {G}io, {V}ietnam). {P}rokaryotic abundance and leucine-aminopeptidase exo-proteolytic activity ({EPA}) were measured at vertical (from the sea-surface microlayer to bottom waters), spatial (along a transect within the estuary) and seasonal (wet and dry season) scales. {P}rokaryotic abundance ranged from 1.2 to 5.7 x 10(9) cells {L}-1 and {EPA} ranged from 24 to 505 nmol {L}-1 h(-1) that was relatively similar to other highly productive ecosystems. {T}he estuary was poorly stratified, most probably because of high water turbulence. {Y}et, exo-proteolytic activity was significantly higher in bottom waters, where higher loads of suspended particulate matter were measured. {S}easonal and spatial differences in {EPA} suggest that the nature of {OM} transported by the {C}an {G}io mangrove estuary affect {EPA}. {T}he latter seems to be increased by two "uncommon" situations: the input of fresh and labile {OM} (e.g. shrimp farm effluents) or the lack of labile {OM} and the need to hydrolyse refractory compounds (e.g. during the dry season).},
