Characterization of culturable bacteria in larval cultures of the Chilean scallop Argopecten purpuratus

Ciencias Marinas, 2011
The early stages of culture of the Chilean scallop Argopecten purpuratus are affected by the mortality attributed to the presence of pathogenic bacteria. The purpose of this study was to characterize the culturable bacteria present in larval cultures of

Reproductive Conditioning of the Peruvian Scallop Argopecten purpuratus in Different Environments

Fishes, 2023
Obtaining viable Argopecten purpuratus seeds faces challenges, especiallyci the unpredictability of the marine environment and high production costs in hatcheries.

The temperate marine Peruvian Province: How history accounts for its unusual biota. [PDF]

Ecol Evol
Among extant temperate marine biotas, the Peruvian Province is highly unusual in, among other traits, a very high incidence of limpets, gastropods with a labral tooth (to assist in predation), a reversed latitudinal diversity gradient, and the absence of several ecological guilds.

Draft genome of the Peruvian scallop Argopecten purpuratus. [PDF]

Gigascience, 2018
Abstract 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.

Microplastic contamination in market bivalve Argopecten purpuratus from Lima, Peru

Manglar, 2019
Microplastics (< 5 mm) are ubiquitous contaminants in the marine environment. Many marine commercial species, among fish, mollusks and crustaceans, are subject to microplastic exposure through ingestion.

Morphological alterations in cryopreserved spermatozoa of scallop Argopecten purpuratus Alteraciones morfológicas en espermatozoides criopreservados de concha de abanico Argopecten purpuratus

Latin American Journal of Aquatic Research, 2010
The present work identifies and quantifies the morphological alterations of scallop Argopecten purpuratus spermatozoa caused by long-term cryopreservation. Percentages of motility, fertilization and injured spermatozoa were quantified by optic microscopy

Effect of temperature on physiological responses of Peruvian scallop Argopecten purpuratus

Revista Peruana de Biología, 2015
The effect of temperature on the clearance rate (CR), ingestion rate (IR) and specific oxygen consumption (SOC) in individuals of Argopecten purpuratus at different size groups were determined.

Reproduction reduces HSP70 expression capacity in Argopecten purpuratus scallops subject to hypoxia and heat stress

Aquatic Biology, 2015
In scallops, gonad production is highly demanding energetically, and reproduction usually occurs during spring-summer, a period of strong environmental changes.

Atypical bacteria accompanying the scallop Argopecten purpuratus [PDF]

Investigaciones marinas, 2002
A simple bacteriological analysis for accompanying culturable microflora from different regions of the body of Argopecten purpuratus showed a rather atypical bacteria considering that farming is done in the sea-water column. High numbers of Vibrio strains, Gram-positive cocci, and sporeformers were present. Also members of the Enterobacteriaceae family
