Environmental DNA, Volume 7, Issue 4, July–August 2025.ABSTRACT Freshwater ecosystems are globally threatened by habitat loss, pollution, and invasive species, all of which are particularly acute in urban areas. To assess the impacts of urbanization on freshwater biodiversity—specifically the effects of alien species on native primary aquatic vertebrates—we investigated the World Heritage Site, Lake ...

Invisible plastics problem in intensive aquaculture: The case of polyvinylpyrrolidone
Reviews in Aquaculture, Volume 16, Issue 4, Page 1544-1554, September 2024.An emerging contaminant of freshwater ecosystems, the water‐soluble synthetic polymer, polyvinylpyrrolidone, is a biodegradation‐resistant pollutant which may be accumulating within aquaculture systems due to its ubiquitous presence in products used as prophylactic and therapeutic agents to culture aquatic species.

Journal of Fish Biology, Volume 104, Issue 1, Page 216-226, January 2024.Abstract A feeding study was conducted to investigate how fish protein hydrolysate (FPH) supplementation affected the growth, feed utilization, body composition, and hematology of juvenile giant trevally (Caranx ignobilis Forsskal, 1775). Seven isonitrogenous (52% protein) and isocaloric diets (10% lipid) were formulated, wherein shrimp hydrolysate (SH)

Aquaculture Research, Volume 2024, Issue 1, 2024.This study investigated the impacts of various inclusion levels of dietary potential of fish protein hydrolysate (FPH) on the growth and reproductive performance, biochemical composition, blood parameters, and liver histology of Ompok pabda broodstock. About 600 pabda broods (11.00 ± 0.05 g) were distributed into 12 cages and fed twice in a day.
