Indigenous Harvest Practices, Seasonality, and Market Pathways of Small‐Scale Clam Fisheries in Coastal Bangladesh

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This study assesses the current status, indigenous harvesting techniques, seasonal dynamics and market value chain to identify constraints and opportunities of the small‐scale clam fishery along the southeast coast of Bangladesh. Data were collected from 216 stakeholders across 11 coastal sites using structured interviews, focus group ...

Development of a method for the determination of SCCPs (short-chain chlorinated paraffins) in bivalve mollusk using Soxtec device followed by gas chromatography-triple quadrupole tandem mass spectrometry

Journal of Analytical Science and Technology, 2018
Background Organochlorinated compounds are major environmental concern due to their persistence, long-range transportability and bio-accumulation. Chlorinated paraffin (CP) mixtures, especially short-chain CPs (SCCPs), are found in environmental samples ...

Food availability impacts oxygen isotope composition in freshwater snail shells

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Freshwater mollusk shells serve as valuable archives for the reconstruction of past environmental conditions as they record water temperatures in their stable isotopic compositions during biomineralization. Yet, the impact of food availability on these isotopic records has never been fully explored.

Description and classification of bivalve mollusks hemocytes: a computational approach

PeerJ, 2018
The fractal formalism in combination with linear image analysis enables statistically significant description and classification of “irregular” (in terms of Euclidean geometry) shapes, such as, outlines of in vitro flattened cells. We developed an optimal model for classifying bivalve

Mussel Spermatozoa Express a Specific Isoform of the Catalytic Subunit of cAMP‐Dependent Protein Kinase

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT cAMP‐dependent protein kinase (PKA) plays a central role in regulating sperm motility in both invertebrates and mammals. The sea mussel Mytilus galloprovincialis provides a valuable model for investigating the molecular mechanisms underlying gamete activation in externally fertilizing organisms.

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...
