Freshwater Aquaculture Dynamics in China’s Jianghan Plain Revealed by Multi-Source Satellite Imagery

The Jianghan Plain is one of the important freshwater aquaculture regions in China. Accurate information on the spatial distribution and spatiotemporal dynamics of aquaculture ponds is essential for regional ecological management. However, large-scale and accurate identification...

Physiological, Transcriptomic, and Metabolomic Insights into Ammonia-Nitrogen Stress in the Hepatopancreas of Litopenaeus vannamei Acclimated to Low Salinity

Elevated ammonia nitrogen significantly reduces the survival rate of Litopenaeus vannamei under low-salinity conditions. Low-salinity culture is widely adopted in shrimp farming but susceptible to ammonia accumulation; however, relevant studies mainly focus on juvenile shrimp und...

Study on the Accumulation, Excretion, and Distribution of Cadmium in Mice After Dietary Exposure to Cadmium-Rich Swimming Crab Portunus trituberculatus

To investigate the patterns of cadmium accumulation and distribution in mice following oral ingestion of cadmium-enriched Portunus trituberculatus, this study selected 4-week-old ICR mice as a model organism. A control group was fed a standard diet, while an exposure group was fe...

Warm Acclimation Modulates the Physiological Responses of Young Saccharina japonica to Marine Heatwaves

Frequent marine heatwaves (MHWs) pose significant threats to and have a profound impact on the structure and functioning of marine ecosystems. The response of marine organisms to MHWs may depend on the background temperature of their habitats. Saccharina japonica is a cold-temper...

Preliminary Kinetic Assessment of Quality Deterioration and Shelf-Life Estimation in Yellowfin Tuna Under Different Constant Storage Temperatures

The quality of yellowfin tuna is highly vulnerable to microbial proliferation, which accelerates quality deterioration and spoilage throughout storage. In this study, the dynamic changes in biogenic amines (BAs), total volatile basic nitrogen (TVB-N), and total plate count (TPC)...

Integrated Physiological and Multi-Omics Analysis Reveals Selenium-Mediated Drought Tolerance in Brassica napus Seedlings

Drought stress severely restricts early growth in Brassica napus, while selenium (Se) can enhance stress tolerance. This study examined how foliar sodium selenite pretreatment affects polyethylene glycol (PEG)-induced drought stress in B. napus seedlings. Seedlings were sprayed w...

A total infectome framework for resolving complex disease etiology in aquaculture

Traditional pathogen isolation can establish disease causality but often fails in complex infections involving unknown or multiple microbial backgrounds, whereas metatranscriptomics comprehensively captures the total infectome without directly resolving the primary etiological ag...

Single‐Cell Transcriptomics and Metabolomics Reveal Glutamate Dehydrogenase as a Central Regulator of Nitrogen Metabolic Remodeling During Alkalinity Adaptation in Crustaceans

ABSTRACT Alkaline environments disrupt ammonia excretion and challenge nitrogen metabolism in aquatic invertebrates, but the underlying cellular mechanisms remain unclear. To elucidate the adaptive mechanisms of crustaceans in highly alkaline environments, the responses of Macrob...

Gill histological, biochemical and transcriptomic responses of Coregonus ussuriensis to acute salinity stress

Salinity is a key environmental factor affecting the osmoregulation and physiological homeostasis in freshwater fish. Juvenile Coregonus ussuriensis has been considered a candidate species for culture in moderately saline waters, but its short-term physiological and molecular res...

Effects of artificial compound feed, mixed feeding and cannibalism of conspecifics on growth performance, physiological status and metabolic gene expression in juvenile barramundi ( Lates calcarifer )

To optimize feeding strategies for juvenile barramundi ( Lates calcarifer ), this study compared the effects of cannibalism-based feeding (CB), formulated feed (FF), and a mixed feeding regime (MIX; formulated feed combined with biological feed) on growth performance, physio-logi...
