Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...

The Occurrence of Microplastic Ingestion in Commercial Marine Fish in Miri, Sarawak, Malaysia

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastics are polymer‐based particle compositions of various toxic chemicals with size less than 5 mm. Due to their small size, microplastics can be ingested and accumulate in body tissues of organisms. This raises concerns about their toxicity being transferred to humans via food consumption.

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

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 ...
