Solution Overview
The smart fishery solution covers ponds, cages, and indoor industrial farms. It monitors water quality, feeds on a schedule, controls aeration, locates fishing vessels, and traces seafood quality, so production and safety management both improve. Aquaculture lives or dies on water quality: dissolved oxygen, pH, and ammonia nitrogen can crash a pond. Marine fishing needs tighter vessel safety and compliance.
It is built on IoT and fishery sensors. Water-quality instruments read dissolved oxygen, pH, ammonia nitrogen, nitrite, temperature, and turbidity as they change. A reading past the limit raises an alarm and starts the aerator. Feeders change amount and frequency with growth stage, weather, and water temperature, so less feed is wasted and less leftover feed pollutes the water. Vessels carry BeiDou/GPS terminals, with geofences, boundary alarms, and track playback, which is what fishery authorities ask to see. Traceability runs from seed stock through grow-out, catch, processing, and sale, and it supports a brand buyers can trust. It fits freshwater farms, marine farms, and ocean fishing, and it is meant to modernize the fishery without wearing the resource down.
What goes wrong, and what changes
The largest risk in a pond is hypoxia. Dissolved oxygen can fall fast enough to kill the fish and shrimp in a few hours. Hand testing and walking the banks happen too seldom to catch that in time. Linked aeration starts the aerators when dissolved oxygen drops below the threshold and stops most of those losses. Growers who added water-quality monitoring and automatic aeration report hypoxia incidents down by more than 80%.
On the vessel side, the Ministry of Agriculture and Rural Affairs requires marine fishing boats to carry BeiDou terminals, report position, keep a geofence, and alarm when they cross it. This solution connects to the fishery authority platform so that requirement is met. Seafood traceability also supports a higher price: a buyer can scan a code and see the grow-out environment and medication records.
