The Selector™ blends and converts existing fish passage and prevention devices from all-or-nothing to automatically selective. It allows native and desired fish species to migrate freely while blocking invasive and undesired fish, using our real-time image recognition and automatic sorting technology.
Benefits
Selective fish passage
The Selector™ allows only the desired fish species to pass over the dam, while preventing the access of invasive or unwanted species. This helps to preserve the native biodiversity and ecological balance of the river.
Volitional and non-invasive fish sorting
The Selector™ does not require any manual handling or delay of the fish, as they volitionally enter the ASPFishway™ and are automatically sorted by the GateKeeper™, based on the FishlRecognition™ imaging. This minimizes the stress and injury to the fish and ensures a humane and efficient fish passage.
Easy integration and adaptation
The Selector™ can be easily integrated with the existing fish passage and prevention infrastructure, such as fish ladders, nature-like bypasses, or weirs, by modifying them with the modular features of the Selector™. This reduces the design, installation, and economic costs of implementing selective fish passage.
Real-time monitoring and verification
The Selector™ provides computational analyses and digital image files, which are sequentially uploaded to the cloud, of the fish that enter and exit the ASPFishway™. This enables easy and accurate fish monitoring and verifiable fish counts for managers and other stakeholders.
How It Works
ASPFishway™
The ASPFishway™ is a volitional and attractive fish passage device that guides fish into the system.
Fish approach the ASPFishway™ entry and swim into the system volitionally, following the water flow and attraction cues.
FishlRecognition™
The FishlRecognition™ , is a high-speed and high-resolution imaging system that identifies the species, size, and direction of each fish in real time.
As fish pass through the FishlRecognition™ unit, their images are captured and analyzed by a deep-learning algorithm that determines their species and other attributes.
GateKeeper™
The GateKeeper™ is an automatic sorting mechanism that opens or closes gates based on the fish identification results, allowing or blocking the passage of each fish.
The GateKeeper™ receives the identification results and activates the appropriate gates to sort the fish according to the predefined criteria (e.g., native vs. invasive, target vs. non-target, etc.).
The sorted fish either continue their upstream or downstream migration or are redirected to a different channel or holding facility, depending on the system configuration and objectives.
