Inheritance of the General Shell Color in the Scallop Argopecten purpuratus (Bivalvia: Pectinidae) [PDF]
Journal of Heredity, 2001 Although some external coloration and pigmentation patterns in molluscan shells may be attributable to environmental factors, most variation in these phenotypic characters depends on uncomplicated genetic mechanisms. Genetic research on inheritance of color variations in the north-Chilean scallop (Argopecten purpuratus) has now been expanded to analyze

Heritability and genetic correlations of escape behaviours in juvenile scallop Argopecten purpuratus
Animal Behaviour, 2012 Escape behaviours are generally considered adaptive because of their obvious effects on fitness. However, little is known about the genetic basis of escape responses. The estimation of the magnitude of hereditary factors affecting variation in escape responses indicates their potential to evolve by natural selection.

Congelamiento de espermatozoides de Argopecten pupuratus Congelamiento de espermatozoides del ostión del norte Argopecten purpuratus mediante congelador mecánico [PDF]
Investigaciones marinas, 2004 The freezing of spermatozoa is a technique used in aquaculture which permits the storage of excess spermatozoa from natural or induced spawning, and saves them for use in subsequent procedures. The cryopreservation process requires gradual, controlled lowering of temperature in order to reduce osmotic shock injury or ice crystal formation in the cells.

Ecology and Evolution, Volume 15, Issue 10, October 2025.The family Anomiidae displays taxonomic ambiguity due to morphological plasticity. We resurrect Heteranomia aculeata and Pododesmus glaucus, while reclassifying Isonomia umbonata as Pododesmus umbonatus. Phylogenetic analyses confirm these revisions and the monophyly of all genera within Anomiidae, with Pododesmus as the earliest‐diverging lineage ...

Spawning and recruitment in the Peruvian scallop Argopecten purpuratus
Marine Ecology Progress Series, 1988 During a 15 mo period (February 1983 to May 1984), spawning and recruitment pulses of the Peruvian scallop Argopecten purpuratus were determined using information on gonad index, larval abundance and recruitment of scallop seed on the natural banks. In situ temperature was simultaneously recorded and showed a marked relation with spawning time as well ...

People and Nature, Volume 7, Issue 10, Page 2465-2485, October 2025.Abstract Small‐scale fisheries represent complex human‐nature interactions, targeting different species in different locations throughout the year. On land, fishers are at the core of diverse seafood value chains that serve local and distant markets.

Aquaculture in Peru: Situation, Challenges and Prospects
Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.ABSTRACT Aquaculture in Peru is a sector with significant growth and development in recent years. However, it faces multiple challenges to ensure its sustainability. This study aims to characterize the Peruvian aquaculture system by analysing the public, private and educational stakeholders involved, as well as the productive, commercial and ...
