Chronic Nitrite Nitrogen Responses in Penaeus monodon: From Growth Phenotypes to Metabolic Hub Signaling

Nitrite nitrogen is a prevalent environmental stressor in intensive shrimp aquaculture that impairs growth and health, yet its chronic effects and underlying molecular mechanisms in Penaeus monodon remain incompletely understood. To address this, we exposed juvenile P. monodon (i...

Photoactive Chiral Nanoneedles for Site-Selective Cleavage and Broad-Spectrum Inactivation of Viruses

Abstract Respiratory viruses spread through aerosols and contaminated surfaces, yet masks, respirators, and filters only trap pathogens without inactivating them, turning used protective equipment into a secondary transmission source. Here, we report chiral ZnO nanoneedles (L-NNs...

The problem of relativity of gel force in laboratory kamaboko

Technological differences in the production of surimi from different types of fish raw materials using decanters and screw presses, as well as the division into first and second lines, depending on the protein source, are con-sidered. It was found that, with identical formal para...

Assessment of the Probiotic Potential of Three Host-Associated Bacillus Species on Growth Performance, Health Status, and Immune Responses of Tomato Clownfish (Amphiprion frenatus)

Antibiotic use in marine ornamental fish farming has raised concerns about resistance and tissue damage, motivating the search for safe probiotic alternatives. In this study, three Bacillus strains—B. subtilis (BS), B. megaterium (BM), and B. velezensis (BV)—that were isolated fr...

Electrochemical Sensor Based on Laser-Induced Graphene for Cortisol Detection in Physiological Media

As a key biomarker for regulating stress levels, timely detection of cortisol can provide an immediate indication of a person’s current stress status and serve as a valuable reference for preventing related diseases. In this study, a laser-induced graphene (LIG)-based electrochem...

Genome-Wide Association Study of Spawning Traits and Candidate Gene Mining in Portunus trituberculatus

Portunus trituberculatus is a commercially crucial marine aquaculture crab species in China, renowned for its high economic value. Spawning performance is one of the most important target traits in selective breeding programs for this species; however, the genetic architecture un...

Effects of body size, temperature, and salinity on survival and growth of Oncorhynchus mykiss during salinity acclimation

This study investigated the individual and interactive effects of body size, water temperature, and ambient salinity on survival and weight gain of Oncorhynchus mykiss during salinity acclimation using a three-factor, three-level orthogonal design to identify optimal acclimation...

Development and application of a low-density 10 K liquid SNP array for genetic improvement in large yellow croaker (Larimichthys crocea)

Developing cost-effective and scalable genotyping platforms is essential for expanding germplasm identification and genomic breeding in aquaculture. However, the high cost of genotyping remains a major constraint on the large-scale application of these approaches in large yellow...
