Biofouling reduction by lantern nets exchange and its relationship with production and survival of Argopecten purpuratus in Samanco Bay, Peru

Journal of the World Aquaculture Society
The aquaculture of Argopecten purpuratus (Peruvian scallop) is a profitable activity with positive impacts on the local economy. However, the development of biofouling on the culture lantern nets generates negative environmental impacts that affect its ...

Plasticity in organic composition maintains biomechanical performance in shells of juvenile scallops exposed to altered temperature and pH conditions [PDF]

Scientific Reports, 2021
The exposure to environmental variations in pH and temperature has proven impacts on benthic ectotherms calcifiers, as evidenced by tradeoffs between physiological processes.

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

Genome-Wide 6mA Map Unveils Epigenetic Adaptation in Deep-Sea Limpet. [PDF]

Ecol Evol
Our study provides the first genome‐wide 6mA profile for any deep‐sea animal, uncovers its sophisticated, context‐dependent role in gene regulation, and functionally links this epigenetic mark to the adaptive pathways essential for deep‐sea survival.
