Mitochondrial genome of the Peruvian scallopArgopecten purpuratus(Bivalvia: Pectinidae) [PDF]

Mitochondrial DNA, 2014
The mitochondrial genome of the Peruvian scallop Argopecten purpuratus was determined. The length of the mitochondrial coding region is 15,608 bp. A typical bivalve mitochondrial composition was detected with 12 protein-coding genes, 2 ribosomal RNA genes and 21 transfer RNA genes, with the absence of the atp8 gene.

Gill Adaptation of the Hong Kong Catfish (Clarias fuscus) to Chronic Heat Stress: Tissue Remodeling, Enhanced Antioxidant Defense and Immune Metabolism Regulation

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Continuous high‐temperature culture altered the structure of gill tissue, enhanced antioxidant capacity, and promoted apoptosis C. fuscus. In response, the organism mitigates extensive apoptosis and strengthens its repair capacity by regulating immune and energy metabolism pathways.

Reproduction Immunity Trade-Off in a Mollusk: Hemocyte Energy Metabolism Underlies Cellular and Molecular Immune Responses

Frontiers in Physiology, 2019
Immune responses, as well as reproduction, are energy-hungry processes, particularly in broadcast spawners such as scallops. Thus, we aimed to explore the potential reproduction-immunity trade-off in Argopecten purpuratus, a species with great economic ...

Low pH Does Not Impact Reproductive Success but Leads to Negative Carry‐Over Effects Between Parents and Larvae in a Mediterranean Gastropod

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We investigated the long‐term effects of ocean acidification on reproduction and early development in the Mediterranean gastropod Hexaplex trunculus. While low pH did not affect spawning or reproductive output, it significantly delayed larval development and reduced the likelihood of reaching hatching, especially when parents were preconditioned to ...

Survival and growth of the Caribbean scallops, Argopecten nucleus and Nodipecten nodosus, in suspended systems at different culture depths and net replacement frequencies

Aquaculture Environment Interactions, 2019
Survival of the Caribbean scallops Argopecten nucleus and Nodipecten nodosus in suspended culture is relatively low. The effects of culture depth and frequency of net replacement on survival and growth of both scallops were assessed, in addition to the ...

Taxonomic Revision of Jingle Shells: Resurrecting and Reclassifying Species of Anomiidae (Bivalvia: Pectinida)

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 ...

Effects of the Toxic Dinoflagellate Protoceratium reticulatum on Physiological Rates of Juvenile Scallops Argopecten purpuratus

Fishes
Protoceratium reticulatum, a dinoflagellate species known for producing yessotoxins (YTX), can form harmful algal blooms (HABs) impacting marine life. This study examined how P.

Effects of temperature and ocean acidification on shell characteristics of Argopecten purpuratus: implications for scallop aquaculture in an upwelling-influenced area

Aquaculture Environment Interactions, 2016
Coastal upwelling regions already constitute hot spots of ocean acidification as naturally acidified waters are brought to the surface. This effect could be exacerbated by ocean acidification and warming, both caused by rising concentrations of ...

Connecting sea to market: Using network analysis to understand social–ecological dynamics in seafood value chains in Pisco, Southern Peru

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.

Early exposure of bay scallops (Argopecten irradians) to high CO₂ causes a decrease in larval shell growth. [PDF]

PLoS ONE, 2013
Ocean acidification, characterized by elevated pCO₂ and the associated decreases in seawater pH and calcium carbonate saturation state (Ω), has a variable impact on the growth and survival of marine invertebrates.
