1. Introduction

...

Echofeeding is an intelligent feeding program designed for salmon. Its desinged to improve the consistency of salmon feeding by using real-time data and algorithms to monitor and adjust the feeding, promoting healthier growth and reducing waste.

...

The main page provides an overview of all the cages at the farm. It helps you create a feeding plan for future meals the next day and visualize the estimated schedule on a timeline.

...

To change feeding setting details for individual cages the user you can use the +/- arrows by the setting or click on the desired setting and type using the keyboard.

...

Meals will automatically start on each cage according to the displayed plan, with intensity adjusted to optimize feeding based on sensor feedback. Users As a feeder you can provide additional input as needed to refine and guide the meals.

...

• Click anywhere over the line from the desired cage to open the control menu > click on ‘'Increased/decreased appetite’'

This action allows users you to provide human input on the fish's response, helping to adjust feeding intensity either higher or lower based on their observed behavior.

3. Cage line: information about what line number the cage is assigned to .

4. Fed today: displays Displays the total amount of feed, in kilos, dispensed in that cage for the entire dayall meals combined.

5. Kg/min: Shows the intensity, in kilo kilos per minute, currently being applied in that cage.

6. Pressure: Displays the current air pressure in the pipes, measured in BAR.

7. Feeding profile: Provides an estimation of the planned meal, including start time and maximum length.

8. Decreased intensity: Displays the previous intensity and indicates . Orange arrows indicate that the feeding intensity has dropped.

9. Increased intensity: Displays the previous intensity and indicates . Green arrows indicate that the feeding intensity has increased.

10. Cage mode: If the cage is not on autonomous mode, there will be an indication showing which its current state it is.

3.2.2 Operation modes

*EF is not sending any comands to the feeding system in the barge

...

• Click anywhere over the line from the desired cage to open the control menu > click on ‘'override control’'

After this is done the user you can continue using EF UI to manually control the feeding and change intensities according to their preferences. This is done if the feeding from EF does not align with the feeder's desired outcomes.

• > click and hold over the red stop icon for 3 seconds

This action is taken if the user wishes you wish to stop the meal. Flushing the pipes will then run for the time the cage is set to have before blowers stop.

...

When doing this the feeding will continue running automatically and events can be sent.

Service Mode

When a cgae cage is set to service mode, the current meal from that cage is paused, allowing the user you to perform actions such as changing the silo without fully stopping the meal in EF. When switching back the meal will resume on EF.

...

What happens when service mode is activated

...

During a meal:

• If service mode is activated during an ongoing meal, the system will automatically flush the pipes for the predetermined amount of time specific to that cage.

• While in service mode, the current meal will be paused until its scheduled end time, this is shown on a countdown. If you do not exit service mode before this time, the meal will end in EF.

• When exiting service mode, the pipes will be flushed again for the same predetermined duration.

• After exiting service mode, the cage will return to manual mode. You can then switch it back to autonomous mode if desired.

...

• Click anywhere over the line from the desired cage to open the control menu > click on ‘'turn off EF and continue feeding from Akva/Fluctus/Scale’' Ömer: do we really need the exact feeding system name? If we need the exact name, will follow up on the existing card Marina suggestion: have ‘monitoring mode’ words on UI TBD with Nikita

By changing from autonomous to monitoring mode while feeding, the cage continues on the current state and the user andyou will need to take control from the feeding system at the barge. When entering this mode no automatic changes will be done by EF and the feeder has you have full control from your local feeding system. This meal will be considered ended in EF UI.

When activating monitoring mode outside a meal nothing will happen, but the user you can control lines from the feeding system at the barge if desired.

Note: This should be done as a last resort from the userfeeder.

4. Troubleshooting

4.1 Common issues

• Planner:

  • I’m not able to approve my plan for tomorrow. Check if:

    • The settings for ‘'Workday start/end’' are correct and not preventing the meals to be distributed.

    • All cages that will be fed have at least one meal.

  • On settings: I can’t increase the minimum intensity for a cage. Check if:

    • Maximum intensity is above minimum before you change it.Vice-versadesired intensity.

    • Minimum intensity is below maximum desired intesity.

• Execution:

  • Feed not coming out. Check if:

    • The correct silo is assigned to the cage.

    • There are any blockages on the silo/screw/feeding hose/spreader top.

    • Power is connected.

  • Flushing the pipes The meal did not start. Check if:

    • The meal is in fact planned to start now.

    • The line is active/enabled* on the feeding program at the barge

    • The cage is not in Monitoring Mode, Manual Mode or Service Mode on EF UI

  • The meal is stopping on EF before I want. Check if:

    • The maximum amount allowed to feed on the Planner was not too low, preventing the meal from continuing.

    • Timeout: The estimated meal time on Execution reached it’s maximum for that meal.
