Water-soluble biological bags are primarily used for aquaculture, serving as bait for fish, shrimp, crabs, and the like. 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 increase the success rate of fishing, involving the addition of special substances to the water to attract fish. Water-soluble bio-bags, as baiting materials, are both eco-friendly and effective, making them a favorite among many fishing enthusiasts.
