Este estudio compara el crecimiento y supervivencia de juveniles de Argopecten purpuratus “concha de abanico” cultivados en sistema de fondo y suspendido en la zona de Casma, Ancash- Perú. Del 29 de Julio y 21 de Octubre del 2006 se instaló un experimento usando “pearl nets” y corrales con individuos de 10mm (0.067g de parte blanda) a densidades de 816, 2450 y 4080 individuos/m2. Cada 2 semanas se colectaron 20 individuos y se registro la altura (mm) y peso de partes blandas (gramos) y mensualmente el número de muertos. Adicionalmente se registró información sobre los costos de producción para comparar la rentabilidad en ambos sistemas. Al final del experimento las tallas y pesos en el cultivo suspendido fueron mayores que en fondo y se relacionaron inversamente con la densidad. Las tasas de crecimiento en talla y peso en el sistema suspendido oscilaron entre 0.07 ...

The scallop soft waste obtained during processing is discarded, generating environmental liabilities to the mariculture industry in Peru. However, these residues constitute a potential raw material to produce meal for balanced feeds. In this sense, a methodology was developed for the elaboration of meal from the soft residues of the Peruvian scallop. The product obtained had a composition of 61% protein, 7.5% fat and 11.7% moisture. The development of technologies that allow the processing of large volumes of waste could contribute to the more efficient and profitable use of this raw material.
