--- The model of Schaefer biomass dynamics was used to assessement the status of the fishery for Anadara tuberculosa y Anadara similis as a single resource black shell. Catch, effort and CPUE data from IMARPE registered in Port Pizarro for the period 1996-2010. The model is solved by process error, which is one of the most used for estimating the parameters of quantitative models; the adjustment was made by maximum likelihood, which presents a good fit of the model according to the biology of the resource. The uncertainty of the model parameters and derived variables were obtained by nonparametric bootstrap. The parameter of the biomass dynamics model were: K: 66036 kg, r: 0.23 kg*year-1 and q: 0.000125, the estimation of the point reference were: RMS: 3806 kg, ERMS: 1489 tasks y FRMS: 0.12. Also the relationship between B2010/K: 0.2, B2010/B1996:0.41 and F2010/FRMS: 2 to make a diagnosis of the resource status. The results of the analysis indicate that the resource is overexploited, found 74% of the biomass at maximum sustainable yield, the biomass projections suggest that the exploitation rate should not exceed 1000 kg to avoid collapse of the fishery.
