Water-soluble biological bags are primarily used for fish farming as bait, suitable for species like fish, shrimp, and crabs. These bags dissolve in water without leaving any residual pollution. They usually contain attractants and fermentation agents to enhance the lure of fish, shrimp, and crabs. Some high-end water-soluble biological bags also incorporate special biological bacteria to improve water quality.

Baiting is one method to enhance fishing success rates, attracting fish to congregate by introducing special substances into the water. Water-soluble bio-bags, as baiting materials, are both eco-friendly and effective, making them a favorite among many fishing enthusiasts.
