The Japanese eel ( Anguilla japonica ) displays a uniquely complex reproductive strategy shaped by its catadromous life cycle, protracted maturation, and extreme sensitivity to environmental cues. Despite decades of research, key regulatory mechanisms governing its reproduction remain unresolved. This review first establishes the biological and ecological foundations of the Japanese eel reproduction, then examines major biolog...

Aquaculture is essential for meeting future demands for food, yet it faces significant losses from infectious bacterial diseases. Aquaculture has recently been critically imperiled by the emergence of multi‐drug‐resistant bacteria, as it relies significantly on the use of antibiotics for prevention and treatment. The emergence of multidrug‐resistant bacteria poses a critical threat to aquaculture, which heavily relies on antib...

The CRISPR/Cas genome editing technology, with its advantages of simplicity, high efficiency, and cost‐effectiveness, has become a key tool for dissecting gene function, knocking out harmful/undesirable genes, and repairing defective genes. It has also shown great potential in the genome editing of aquatic animals such as tilapia, carp, salmon, and sea urchins. Disease prevention and control are core areas of aquatic animal re...
