Application of water pumps in the fishery industry

I. Main Uses

Pond/Fishpond Water Exchange

Draws river, well, and lake water into ponds, removing old and polluted water, improving water quality, and preventing fish diseases.

Oxygenated Water Circulation

Combined with piped water circulation for oxygenation, the flowing water increases dissolved oxygen levels, suitable for high-density aquaculture.

Aquaculture Water Pumping

Stores and replenishes water in fry ponds and rearing ponds, stabilizing water levels.

Pond Sludge Removal and Cleaning

Pumps out silt, wastewater, and uneaten feed from the pond bottom, cleaning and draining the pond.

Fishpond Cooling and Heating

Introduces cool water to lower the temperature in summer and regulates water temperature in winter, stabilizing the aquaculture environment.

Fish, Shrimp, and Crab Seedling Water Supply

Provides clean and circulating water to seedling ponds, improving seedling survival rates.

Cage Aquaculture Water Supply

Drains flowing water from near-shore and river cages, improving the aquaculture environment.

Fish Farm Spraying and Disinfection

Pumps water to prepare disinfectant, spraying the entire pond for disinfection and water sterilization.

Recirculating Aquaculture System (RAS)

Enables factory-style water circulation and filtration for high-density, water-saving aquaculture.

Fishing Vessel Water Use

Used for cleaning fishing vessels, flushing fishing ports, and water supply and drainage for fisheries.

II. Commonly Used Water Pumps in Fisheries

• Submersible Pumps: For deep-water pumping and large-area water exchange in fishponds.
• Self-priming Pumps: For convenient pumping from the bank and replenishing water in small fishponds.
• Aeration and Circulation Pumps: For circulating live water and dedicated to flowing water fish farming.
• Corrosion-resistant Sewage Pumps: For pumping dirty water and sludge from the bottom of ponds.
• Clean Water Booster Pumps: For precise water supply to nursery ponds.

III. Core Functions

1. Regulates and circulates water, reducing oxygen deficiency caused by fish and shrimp surfacing.
2. Purifies water, reducing disease incidence.
3. Promotes water-saving aquaculture, increasing stocking density and yield.
4. Meets water requirements throughout the entire process of water storage, exchange, drainage, temperature regulation, and disinfection.
