  abstract = {{T}he gathering of invertebrates during low tides is a traditional activity across the {P}acific islands, but it still remains poorly documented. {R}ecreational invertebrate harvesting was investigated in 2008 and 2009 in the coastal/islet reef flats surrounding {N}oumea, the main urbanized area in {N}ew {C}aledonia ({S}outh {P}acific). {H}uman frequentation, harvesting effort, captures and their impacts on the density and size structure of the main targeted species were simultaneously quantified. {I}nvertebrate harvesting was restricted to a 5-months winter period ({A}pril-{A}ugust), depending mainly on low tides. {F}requentation (similar to 10,000 persons year(-1) for an area of 324 ha) was a relevant proxy of harvesting pressure, with higher impacts on coastal flats compared to islet flats with respect to distance from city town and accessibility. {O}n the whole, harvesters collected 8.4 +/- 0.7 t year(-1) of invertebrates (more than 60 species, mainly molluscs), with a mean of 8 harvesters ha(-1) over the year. {T}hree clam species accounted for 50% of the total catch biomass (shell inclusive), with decreasing occurrences along the harvesting period emphasizing a reduction of the largest individuals. {H}arvesting-related disturbance mostly impacted the largest size classes, which constituted a minor (i.e. 3%) part of the reproductive adults. {T}he 7-months non-harvesting period is likely to constitute a recovery period for the target species, with harvesting impacts on the natural populations less severe than initially expected.},
