Sea lice mitigation via predictive health modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sea lice infestations in fish farming pose a significant problem, leading to unhealthy fish that are unsuitable for human consumption, and existing methods lack efficiency in predicting and mitigating infestations to minimize environmental impact.
Innovation Solution
A system that uses observations of fish across their lifecycle to train a model for predicting health indicators, allowing for selective sea lice mitigation based on predicted health outcomes, reducing the need for unnecessary treatments and conserving resources by only treating fish likely to benefit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sea lice mitigation is applied to all fish, then fish health is improved, but resource consumption and environmental impact increase
Solution Approach 1:
The system performs preliminary health assessments and sea lice infestation predictions before mitigation treatment is applied. By using machine learning models trained on historical fish observations to predict which fish are likely to develop sea lice infestations, the system enables proactive targeting of specific fish that need treatment, rather than treating all fish preventively. This preliminary identification action resolves the contradiction by ensuring mitigation resources are allocated only where necessary.
Solution Approach 2:
The system applies sea lice mitigation selectively to individual fish or specific groups based on their predicted risk levels and current health status, rather than applying uniform treatment to the entire population. Each fish receives treatment based on its local condition and predicted needs, optimizing resource usage while maintaining fish health where necessary.
2Reliability
If sea lice mitigation is applied to all fish, then fish health is improved, but environmental impact worsens
Solution Approach 1:
The system uses historical observation data and machine learning models to predict sea lice infestation risks before treatment is applied. This preliminary prediction enables selective mitigation only for fish likely to be affected, reducing the overall amount of mitigation substances released into the environment while still protecting fish health where needed.
Solution Approach 2:
By targeting mitigation treatment to specific fish based on individual risk assessment rather than blanket treatment, the system minimizes the environmental footprint of mitigation substances. Only the necessary minimum amount of treatment is applied to specific locations (individual fish), reducing harmful environmental factors.
3Measurement precision
If comprehensive fish monitoring is implemented, then prediction accuracy is improved, but system complexity increases
Solution Approach 1:
The system employs a unified machine learning platform that processes multiple types of fish observations (visual inspections, health metrics, environmental data) through a single trained model. This multi-functional approach achieves comprehensive monitoring and high prediction accuracy without requiring separate complex systems for each type of data collection or analysis.
Solution Approach 2:
The system uses historical observation data as training copies to build predictive models. By learning from past fish health data and patterns, the model achieves accurate predictions without requiring real-time complex monitoring of every parameter, reducing the operational complexity while maintaining high prediction accuracy.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for sea lice mitigation. In some implementations, a method includes obtaining multiple observations of a population of reference fish across a period of time, generating, from the multiple observations, a record for each reference fish that indicates an extent of sea lice infestation for the reference fish across the period of time, training, based on the records, a model that determines a predicted health indicator for a fish, obtaining an image of a sample fish that is not in the population of reference fish, determining, based on the image of the sample fish and with the model, a predicted health indicator for the sample fish, and selectively initiating sea lice mitigation based on the predicted health indicator.
