Singapore grouper iridovirus (SGIV) is a major viral pathogen threatening grouper aquaculture. The lack of specific antiviral drugs underscores the urgent need to develop safe and effective control strategies. This study demonstrates that tannic acid (TA) exhibits significant anti‐SGIV activity in vitro. In grouper spleen (GS) cells, TA inhibited SGIV replication in a concentration‐dependent manner. Time‐of‐addition assays con...

Singapore grouper iridovirus (SGIV) is a highly pathogenic virus that causes substantial economic losses in marine grouper aquaculture, and effective antiviral agents are currently lacking. In this study, the anti‐SGIV activity of epigallocatechin gallate (EGCG), a natural compound from green tea, was evaluated and its underlying mechanisms were investigated. Cytotoxicity assays showed that EGCG at concentrations up to 12.5 μg...

Estuarine ecosystems are vulnerable to anthropogenic heavy metal pollution. This study examines cadmium (Cd) dominance in pollution and its ecological/human health impacts in China's Guanhe Estuary, a region heavily influenced by land-based inputs. Concentrations of six heavy metals (Cu, Pb, Zn, Cd, Cr, As) were measured in sediments and muscle tissues of 12 marine species across 11 sampling sites using atomic absorption and f...
