Feed Smart software manages food delivery based on user-selectable inputs to manage feed delivery based on number of daily feedings, daily feed weights, total biomass and FCRs, along with parameter control based on water quality values. interfaces with most auto feeders.

AquaManager desktop software provides the ability to instantly see an overview of your facility, manage parameter set points, and conveniently manage data to make informed operation decisions. If you're interested in a continuous monitor for dissolved oxygen, please visit the 5500D (optical dissolved oxygen) or 5400 (galvanic dissolved oxygen) page.

The YSI IOEM and REM expansion modules increase the flexibility and capability of the YSI aquaculture platform when networked with 5200A, 5400 or 5500D instruments. Configure 4 (IOEM-4) or 8 (IOEM-8) analog channels as inputs or outputs for the ability to integrate 3rd party sensors or output from other devices. Outputs can be configured to control pumps, UV systems, analog valves, or send data to SCADA/ PLC systems. REMs (Relay Expansion Module) add relays where needed to control feeders, lighting, heaters, alarming, and more.

Designed specifically for Aquaculture Systems, the YSI 5500D and AquaManager® Software integrate process control, alarming, and data management into one product. Simple enough to monitor one tank, powerful enough to manage a full scale farming operation from anywhere in the world. Simultaneously measure dissolved oxygen with optical technology in multiple tanks or ponds.

Optical Dissolved Oxygen (DO) Meter for Continuous Monitoring and Control

5500D monitors and their optical probes proved to be a valuable tool for the management of super-intensive shrimp culture, allowing quick adjustments to be made to minimize stress from low DO while setting upper and lower DO limits helped to optimize oxygen use.

Designed specifically for aquaculture systems, the YSI 5500D continuous monitor for dissolved oxygen and AquaManager® Software can be used to integrate process control, feeding, alarming and data management into one product or can be used to simply monitor one tank. With YSI's ODO® optical dissolved oxygen technology you'll benefit from reduced costs, less maintenance and better data. The ODO sensors require no membrane changes, no electrode cleaning, no stirring requirement and less frequent calibrations.

The standard conditional feed timer, Feed Smart, manages food delivery based on user's preset criteria. Manage feed delivery based on user-selectable inputs for the number of daily feedings, daily feed weights, total biomass and feed conversion ratios (FCRs), along with parameter control based on water quality values. Interfaces with most auto feeders.

Optional AquaManager® desktop software allows you to view, configure, or setup instruments from the convenience of one central location. Instantly see an overview of your facility, manage parameter set points, and conveniently manage data to make informed operational decisions. The facility mapping feature provides an immediate overview of all ponds or tanks indicating their current state.
