Investigation into Cryptosporidium and Giardia in bivalve mollusks farmed in Sardinia region and destined for human consumption

Italian Journal of Food Safety, 2013
Cryptosporidium and Giardia are protozoan parasites transmitted by fecal-oral ingestion of (oo)cysts, and are responsible for enteritis in several animal species and humans worldwide.

Tissue‐Specific Plasticity of DNA Methylation Across Intertidal Microhabitats in Juvenile Mussels (Mytilus californianus)

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Epigenetic modifications to DNA are proposed to underpin plastic responses to environmental change, and the manner in which DNA methylation contributes to plasticity likely differs among tissues. However, few studies have investigated tissue‐specific DNA methylation responses to ecologically relevant environmental stressors in natural settings.

Yellowish coloration of oyster Crassostrea gigas.

NIPPON SUISAN GAKKAISHI, 1987
Recently yellowish colored oysters, so called “Kigaki”, were found in Kesennuma Bay, Maizuru Bay and Hiroshima Bay. They showed yellow body fluid in the normal colored soft body. The yellowish coloration of oysters was temporazy and the yellow pigment disappeared in a few weeks (half time 2-3 days).

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Resistance to OsHV-1 Infection in Crassostrea gigas Larvae [PDF]

Frontiers in Marine Science, 2016
The ostreid herpesvirus (OsHV-1) is one of the major diseases that affect the Pacific oyster Crassostrea gigas. Selective breeding programs were recently shown to improve resistance easily to OsHV-1 infections in spat, juvenile and adult oysters. Nevertheless, this resistance has never been investigated in larvae, whereas this developmental stage has ...

Comparative transcriptomic analysis reveals a differential acid response mechanism between estuarine oyster (Crassostrea ariakensis) and Pacific oyster (Crassostrea gigas)

Ecotoxicology and Environmental Safety
Ocean and coastal acidification (OCA) poses a significant and rapidly emerging threat to mollusks. The physiological resilience of mollusks to OCA varies considerably; however, the underlying molecular mechanisms remain poorly understood.

Life Cycle Assessments of Bivalve Aquaculture: A Systematic Review and Meta‐Analysis

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
Life cycle assessment (LCA) of bivalve aquaculture systems indicates generally low environmental impacts across mussel, oyster, and clam production. For a functional unit of 1 t live weight bivalves at farm gate, median impacts were 385 kg CO2‐eq for climate change, 0.25 kg PO43−‐eq for eutrophication, 0.014 kg N‐eq for marine eutrophication, 1.86 kg ...

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.
