The dynamics of production of the giant lions-paw scallop Nodipecten subnodosus were studied at a coastal location within the ‘El Vizcaíno’ Biosphere Reserve, Mexico. Production parameters were estimated testing three culture densities. The basis to control cultivation density 60, and 80% of the area occupied by scallops in nestier . The oogenic cycle and biochemical composition of the ovary of raft-cultured great scallop (Pecten maximus) were studied during the period April –July The ovary condition index (FGI) and stereological studies showed the existence of two principal spawning periods, winter and late spring-early summer. No sexual resting period was found.
About 40% of the bay scallops examined were infected, as well as many giant sea scallops, Placopecten magellanicus (Morrison and Shum ). Basophilic staining (haematoxylin and eosin) spherical, or sub-spherical, inclusion bodies were seen within intracellular vacuoles in the epithelial cells of the blind-ending tubules of the digestive. The book highlights the following aspects of prawn and its culture methods: taxonomy, morphology and biology of prawn. Hatchery, culture technique and diseases of the prawn are described in detail. This edition deals exclusively with the design and construction of the rearing ponds, management practices and feeding strategies.".

Scallop aquaculture is the commercial activity of cultivating (farming) scallops until they reach a marketable size and can be sold as a consumer juvenile scallops, or spat, were collected for growing in Japan as early as The first attempts to fully cultivate scallops in farm environments were not recorded until the s and s.
The Second Edition is the only comprehensive treatise on the biology of scallops and is the definitive reference source for advanced undergraduate and graduate students, mariculturists, managers and researchers.
It is a valuable reference for anyone interested in staying abreast of the latest advances in Edition: 2. Scallops: Biology, Ecology, Aquaculture and Fisheries, Third Edition, continues its history as the definitive resource on scallops, covering all facets of scallop biology, including anatomy, taxonomy, physiology, ecology, larval biology, and neurobiology.

A scallop is a marine bivalve mollusc of the family ps live in all the world's oceans. This is one of the largest families of living bivalves.
There are over living species of scallop. Their main adaptation is the ability to swim by clapping their valves together. In this way they escape from most of their predators. They have a good reputation as a food source. Placopecten magellanicus, previously listed as Pecten tenuicostatus and as Pecten grandis and once referred to as the "giant scallop", common names Atlantic deep-sea scallop, deep sea scallop, North Atlantic sea scallop, American sea scallop, Atlantic sea scallop, or sea scallop, is a commercially important pectinid bivalve mollusk native to the northwest Atlantic Ocean.
Scallop (/ ˈ s k ɒ l ə p, ˈ s k æ l ə p /) is a common name that is primarily applied to any one of numerous species of saltwater clams or marine bivalve mollusks in the taxonomic family Pectinidae, the r, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also.
Short-term feeding experiments with starved giant scallops Placopecten magellanicus Gmelin show that there is an interaction between ambient velocities and cell densities of a preferred unialgal diet offered, such that at high concentrations, flow-inhibited feeding persists at higher velocities.
This result implies that there is homeorheostatic control of feeding in the giant scallop. The effect of stocking density on the growth of juvenile giant scallops, Placopecten magellanicus (Gmelin, ) (Bivalvia: Pectinidae), was assessed for 1 year in Passamaquoddy Bay, N.B., Canada.
Scallop spat (initial shell height = 10–15 mm) were held in suspension culture (pearl nets) at six different stocking densities ranging from to spat.

The biology of young scallops Pecten maximus (Mollusca: Bivalvia) was examined using SCUBA diving. Within shallow and sheltered bays settlement took place near adult populations. Surfaces to which scallops attached were generally free of silt; these included algae, invertebrate tests and inorganic materials.
Under optimum growingconditions, 16 scallops/cage suspended 10 m from the bottom, scallops grewto 10 cm shell length (legal size) by February In ear hanging culture.Abstract. In January and February an experiment was conducted in a m deep tank (diameter: m, volume: m 3) to examine the effects of food distribution with respect to a stable thermocline, depth, and substratum type on the settlement and metamorphosis of larvae of the giant scallop, Placopecten magellanicus (Gmelin).

Molluscs play a variety of roles in culture, including but not limited to art and literature, with both practical interactions—whether useful or harmful—and symbolic uses.
Practical interactions with molluscs range from their use as food, where species as diverse as snails .
