Most farming of Peruvian scallops occurs in the northern part of Peru, close to Piura. Only 5% of the farming takes place in the south of Peru, close to Pisco. Between these areas, the Humboldt Current has cold water, perfect for giant squid (genus Architeuthis), but which is not suitable for scallop farming. In the north, the Bay of Sechura and the Bay of Guaynumá (Acuapesca principally) give a favorable natural protection for scallop farming.
In the Bay of Sechura, the Peruvian government divided the area for scallop farming into 100 concessions or designated areas. Each concession has a different size. A concession holder has the obligation to use his area(s) for scallop farming for between 10 and 30 years. Nevertheless, he can let his area to one or several smaller farmers. The 100 concessions holders are registered by the authorities. However, possible subcontractors are not known officially. That is why it is difficult to know the exact number of farmers. A rough estimation would be 10 big farmers, 30 medium-scale farmers and 150 smaller farmers.
After depositing the larvae, nature does the rest of the process of farming. With bottom farming, there is no intervention by humans at all. With hanging scallop farming, the pearl nets with the scallops are taken out of the water each 3-4 months and put on floating process platforms. Here, the scallops are selected upon size. From there, the scallops are put again in pearl nets of different sizes: L1 (15 mm net) for a density of 120-80 scallops per floor and a size of 35-40 mm each, L2 (21 mm net) for a density of 80-40 scallops per floor and a size of 40-55 mm each and L3 (31 mm net) for a density of less than 40 scallops per floor and a size of 55-60 mm each. Until now, only Acuapesca has the ASC and Friends of the Sea certifications. Other farmers are just starting the process of implementation of these certificates.
