Question 1

How does RationFEED count uneaten pellets?

Accepted Answer

RationFEED uses patented optical methods and AI to count uneaten pellets escaping through the effluent in real time. The camera is mounted outside the water, looking into the outflow pipe, and distinguishes pellets from fish waste even in turbulent flows.

Question 2

Which feeding systems are compatible?

Accepted Answer

RationFEED works with any feeding system that includes an API. Current integrations include Scale, AKVA Group, Arvotech, Fluctus, and Laksesystemet. A local computer with read and write access to the feeding system is required for automatic control.

Question 3

How is RationFEED installed?

Accepted Answer

The camera is mounted outside the water using custom fasteners fitted to your tank setup. No submerged equipment is needed. Installation typically completes the same day, with full calibration within about two weeks.

Question 4

Does the camera need regular maintenance?

Accepted Answer

The camera and optics are designed to be self-cleaning and operate out of water, so routine cleaning is not required. This means control remains stable and unaffected by biofouling or maintenance schedules.

Question 5

How does automatic feeding control work?

Accepted Answer

When RationFEED detects that pellet waste is increasing or decreasing, it automatically adjusts the appetite factor on your feeding system. This keeps feeding matched to fish appetite in real time, reducing waste and improving water quality.

Question 6

How does RationOVA integrate with our conveyor belt?

Accepted Answer

RationOVA mounts above your existing conveyor belt system. Computer vision captures and analyzes each ovum as it passes, counting and grading at full production speed without slowing your line.

Question 7

Can RationOVA detect defective ova?

Accepted Answer

Yes. RationOVA uses computer vision to identify and sort defective ova automatically. Grading is consistent regardless of operator or shift, replacing the variability of manual inspection.

Question 8

What throughput can RationOVA handle?

Accepted Answer

RationOVA processes ova at conveyor belt speed, handling high volumes without bottlenecks. Exact throughput depends on your line speed and ova size, which we configure during installation.

Question 9

What data does RationOVA provide?

Accepted Answer

Real-time counts and quality metrics are available on a cloud dashboard. You can track batch quality over time, view cumulative counts and defect rates, and export data for traceability and compliance.

Question 10

What species and systems does RationOVA support?

Accepted Answer

RationOVA is designed for salmon ova on conveyor belt systems used in hatchery and broodstock operations. Custom positioning is configured for your specific line speed and ova size.

Question 11

How does RationCOUNTER avoid double counts?

Accepted Answer

RationCOUNTER uses computer vision to track individual fish as they pass through a controlled channel. Each fish is captured across multiple frames, which prevents double counts and missed fish even at high flow speeds.

Question 12

Can RationCOUNTER measure fish size and weight?

Accepted Answer

Yes. Each fish is individually imaged, providing size measurements and weight estimates. Session summaries include total count, throughput, and detailed size distribution data for biomass planning and reporting.

Question 13

Is the counting process safe for the fish?

Accepted Answer

The counter is designed with fish welfare as a core priority. The passage geometry supports smooth, continuous flow with minimal obstruction and short handling time. Fish pass individually through a controlled channel under conditions that reduce stress.

Question 14

How is RationCOUNTER installed?

Accepted Answer

RationCOUNTER integrates into existing pipe or raceway systems with custom mounting for your facility layout. Transfers and grading events are the ideal counting opportunity since each fish passes individually.

Question 15

What species does RationCOUNTER support?

Accepted Answer

RationCOUNTER works with any fish species in land-based aquaculture. It is designed for counting during transfers and grading where fish pass through pipes or raceways.

Question 16

What species and farm types does Ration support?

Accepted Answer

RationFEED was initially designed for land-based salmon farms but works with any species in recirculating or flow-through systems. RationOVA handles salmon ova on conveyor belt systems. RationCOUNTER counts and measures live fish of any species.

Question 17

How long does installation take?

Accepted Answer

RationFEED is typically installed and counting waste pellets the same day. We can provide custom fasteners to suit all tank set ups. Full calibration takes about two weeks. No submerged equipment required.

Question 18

Does RationFEED work with my existing feeding system?

Accepted Answer

RationFEED works with any feeding system that includes an API. Current integrations include Scale, AKVA Group, Arvotech, Fluctus, and Laksesystemet.

Question 19

Can I try RationFEED before committing?

Accepted Answer

Yes. RationFEED trials are offered on a rental contract. If the device does not improve your operations during the trial period, you can return it for a full refund.

Question 20

Do you offer local support outside Iceland?

Accepted Answer

Yes. Ration has service agents in Iceland, Norway, Chile, and the UK. We provide on-site installation, training, and ongoing technical support.
