This work evaluates the impact of the pink shrimp Farfantepenaeus paulensis (Perez-Farfante, 1967) fishery on fish and crab assemblages of Lagoa do Peixe National Park, Brazil. We observed that composition of catches is similar to shrimp fisheries using fyke-net at others estuaries of Rio Grande do Sul State: pink shrimp (53%), accessory catches (24%) and bycatch (23%). However, fishery composition showed distinct differences along the saline gradient of the main park's lagoon. Regarding only fish species, the most impacted species in this fishery were Brevoortia pectinata (Jenyns, 1842), Micropogonias furnieri (Desmarest, 1823), and Jenynsia multidentata (Jenyns, 1842). In others estuaries from Rio Grande do Sul, in contrast, the most impacted species were M. furnieri, Genidens barbus (Lacepède, 1803) and Genidens genidens (Cuvier, 1829). The potential impact of the pink shrimp fishery at Lagoa do Peixe National Park seemed to be weaker when compared to shrimp fisheries elsewhere. We believe that the decision to prohibit this fishery at the Lagoa do Peixe National Park should not be based on its potential damage to the fish and crab assemblages but based on the simple fact that Brazilian laws do not allow fisheries inside National Parks.

The objective of the present study was to evaluate the potential of a heterotrophic rearing media (microbial flocs) on the growth and survival of Farfantepenaeus paulensis reared in the nursery phase. For 30 days, F. paulensis post-larvae (0.019 ± 0.01g) were reared in nine 40-liter plastic tanks at the density of 500 post-larvae m -2. Three treatments with three replicates each were used: rearing in the presence of microbial flocs with ration supply (FLOC + R); rearing in the sole presence of flocs - no ration supplied (FLOC); and rearing in clear water plus with ration supply (AC + R). The presence of microbial flocs had no significant effect on growth and survival in the nursery rearing of F. paulensis.
