  abstract = {{W}e conducted a mesocosm study to investigate the combined effect of organic enrichment and sediment resuspension by shrimp on phytoplankton communities in shrimp aquaculture ponds. {H}ence, the factorial design included 2 factors: (1) shrimp density with a concomitant increase of feed input, resulting in organic enrichment, and (2) access of shrimp to the sediments. {I}ncreasing feed input in the system raised the eutrophication state of the environment, characterized by an increase in phytoplankton biomass. {B}ioturbation enhanced: (1) mineralization of organic matter via the microbial loop, resulting in faster nutrient recycling, (2) primary production and (3) buffering capacity against eutrophication consequences. {T}he phytoplankton community showed both large temporal variations of its taxonomic composition and resilience to treatments. {A} shift in species dominance from diatoms + dinoflagellates to green algae was observed in all treatments and coincided with meteorological and {N} pool changes. {R}esults suggest that algal production was primarily limited by phosphorus and light at low (i.e. low feeding) and high (i.e. high feeding) eutrophication states, respectively. {G}rowth rate of species to be a major factor favoring their dominance in the phytoplankton community in this highly dynamic ecosystem. {C}onsequences for water column management are discussed.},
