The Peruvian scallop (Argopecten purpuratus) has become the most important cultivated species for exports. This study consisted in determining the production and value of the scallop biomass in relation to the size and sowing density in a suspended system using the simplified model of THOMPSON and BELL (1934) assuming an initial sowing of 9600000 individuals. During October 2016 and January 2017, the growth and mortality of adult individuals with three ranges of sizes (35 to 45; 55 to 65; 70 to 80 mm) were evaluated at densities of 10, 20,40 and 60 ind / floor. Additionally, the growth and mortality of pre-adults were evaluated at densities of 100, 200, 400, 600 and 800 ind / floor. The results indicate that in both pre-adult and adult individuals there is an inverse relationship between density and growth. The pre-adults of 11.8 mm on average reached the size of 30 mm in 50 and 100 days depending on the density. The adult growth rate varied between 0.032 - 0.44 mm / day depending on density and size. The mortality rate in adults did not show a relationship between density. The maximum biomass was inversely proportional to the density and varied between 66 and 143 t of abductor muscle and between 102 and 222 t of abductor muscle + gonad. the maximum economic value of the abductor muscle was 4.43, 3.09, 2.5 and 2.03 million US $; and for the abductor muscle + gonad it was 9.53, 5.69, 6.34 and 4.38 million US$ respectively and the optimal harvest size varied between 76 mm and 85 mm according to density, price and product. The growth of pre-adults and adults in Los Órganos is similar to that of other areas where its cultivation takes place, so in biological terms it is possible to develop its cultivation in this area
