Abstract

A method for external fish parasite monitoring in aquaculture, comprising the steps of:submerging a camera (52) in a sea pen containing fish, the camera having a field of view;capturing images of the fish with the camera (52); andidentifying external fish parasite on the fish by analyzing the captured images, characterized in thata target region within the field of view of the camera (52) is illuminated from above and below with light of different intensities and/or spectral compositions.

First claim

What is claimed is:

1. An end-user interface for a system for external fish parasites monitoring in aquaculture, said system comprising:
a camera suitable to be submerged in a pen suitable for containing fish, the camera being arranged for capturing images of the fish;
a lighting system; and
an electronic image processing system configured for identifying external fish parasites on the fish by analyzing the captured images;
wherein the electronic image processing system comprises a fish detector configured to recognize a silhouette of a fish in the captured image, and an external fish parasite detector configured to detect external fish parasites in the silhouette of the fish;
and wherein the end-user interface integrates with additional aquaculture tools.

2. An end-user interface according to claim 1 , wherein the end-user interface includes predictive analytics tools.

3. An end-user interface according to claim 2 wherein the predictive analytics tools are selected from the group consisting of forecasting infestation rates for the fish population, forecasting the resulting economic impact and evaluating possible courses of actions.

4. An end-user interface according to claim 3 wherein the courses of action that is evaluated comprises applying a chemical treatment.

5. An end-user interface according to claim 1 wherein the aquaculture tools are selected from the group consisting of tools monitoring biomass, oxygen levels, and salinity levels.

6. An end-user interface according to claim 1 wherein the end-user interface further includes tools that ease regulatory compliance.

7. An end-user interface according to claim 1 wherein the end-user interface provides summary statistics.

8. An end-user interface according to claim 1 , wherein the end-user interface enables adjustment of the parameters governing the behavior of the camera and lighting control system.

9. A method for monitoring external fish parasites in aquaculture, said method comprising:
illuminating a target region with a lighting system;
capturing images with a camera submerged in a pen suitable for containing fish;
processing the captured images with an electronic image processing system configured for identifying external fish parasites on the fish by analyzing the captured images;
wherein the electronic image processing system comprises a fish detector configured to recognize a silhouette of a fish in the captured image, and an external fish parasite detector configured to detect external fish parasites in the silhouette of the fish;
displaying information on the identified external fish parasites via an end-user interface system;
wherein the end-use interface system integrates the information on external fish parasites with additional aquaculture tools.

10. The method according to claim 9 , wherein the end-user interface integrates the information on external fish parasites with predictive analytics tools.

11. The method according to claim 10 , wherein the predictive analytics tools are selected from the group consisting of forecasting infestation rates for the fish population, forecasting the resulting economic impact and evaluating possible courses of actions.

12. A method according to claim 11 , wherein the courses of action that is evaluated comprises applying a chemical treatment.

13. A method according to claim 9 , wherein the aquaculture tools are selected from the group consisting of tools monitoring biomass, oxygen levels, and salinity levels.

14. The method according to claim 9 , wherein the end-user interface provides information that eases regulatory compliance.

15. The method according to claim 9 , wherein the end-user interface provides summary statistics.

16. The method according to claim 9 , wherein the end-user interface enables adjustment of the parameters governing the behavior of the camera and lighting control system.
