Background: The Peruvian scallop, Argopecten purpuratus, is mainly cultured in southern Chile and Peru was introduced into China in the last century. Unlike other Argopecten scallops, the Peruvian scallop normally has a long life span of up to 7 to 10 years. Therefore, researchers have been using it to develop hybrid vigor. Here, we performed whole genome sequencing, assembly, and gene annotation of the Peruvian scallop, with an important aim to develop genomic resources for genetic breeding in scallops. Findings: A total of A draft genome assembly of

Argopecten purpuratus Lamarck, - exterior of the left valve of a purple scallop. Bivalves are bilaterally symmetrical molluscs having two calcareous, asymmetrical shells valves - they include the clams, oysters, and scallops. In most bivalves, the two shells are mirror images of each other the major exception is the oysters. They occur in marine, estuarine, and freshwater environments.
Bivalves are also known as pelecypods and lamellibranchiates. Bivalves are sessile, benthic organisms - they occur on or below substrates. Most of them are filter-feeders, using siphons to bring in water, filter the water for tiny particles of food, then expel the used water. The majority of bivalves are infaunal - they burrow into unlithified sediments. In hard substrate environments, some forms make borings, in which the bivalve lives.
Some groups are hard substrate encrusters, using a mineral cement to attach to rocks, shells, or wood. The fossil record of bivalves is Cambrian to Recent. They are especially common in the post-Paleozoic fossil record. Scallops are distinctive bivalves with nearly symmetrical valves. The convexity and color of the two valves of an individual can vary dramatically in many species.

Argopecten purpuratus (purple scallop) 1
Argopecten purpuratus is an edible marine species of saltwater shellfish, a bivalve mollusk in the family Pectinidae. This scallop is natural to certain bays in the Southern west coast of south America, from Peru to Chile. In most growth areas, the harvesting of natural grown scallops has been replaced by aquaculture operations. The aquaculture operations consist in re-stocking the natural areas, taking care of the scallops along the grow out period and harvesting at the end of the cycle. Thanks to this practices, the natural banks have recovered and are able to maintain a sustainable production level. From Wikipedia, the free encyclopedia.
