Acoustic Telemetry

The movement of tagged fish and invertebrates is monitored through detections at acoustic receivers deployed over varying spatial scales.

Talk to an expert

Individuals tagged with an acoustic transmitter are detected at receivers when they pass within tens to hundreds of meters, thus providing information on an individual’s presence, site fidelity, and movement patterns.

Inspire is partnering with researchers at Monmouth University, Stony Brook University, and New England Aquarium to leverage information gained from tagged fish species that are detected on acoustic telemetry arrays deployed on the northeastern US continental coast.

Acoustic receiver arrays can be deployed around a project site to track fish and invertebrate activiity in the area and detect potential changes to movement patterns consistent with either attraction or avoidance behavior.

Understanding migrations and site fidelity

Acoustic telemetry provides information on animal presence and movement over broad spatial scales (hundreds of meters to hundreds of kilometers) and time periods (days to years).
Data sharing among researchers with acoustic receiver arrays and tagging programs enhances the scientific understanding of tagged animal behavior, benefiting all who participate.
Acoustic telemetry networks leverage funding, effort, and scientific expertise to improve study results
Collaboration among researchers that share detections of fish tagged by colleagues amplifies scientific knowledge.
Acoustic telemetry methods are suited to gradient study designs
Deploying acoustic receivers at increasing distances from a project source, such as an export cable, provides information on attraction or avoidance behaviors.
Tagging fish and crustaceans has minimal effects on survival.
Surgical placement or adhesion of acoustic tags has low rates of detrimental effects on fish and crustacean behavior and survival.
Acoustic tag detection data can be paired with benthic resource quality
Detections of tagged animals by acoustic receivers can be compared to mapped benthic features to inform project and resource managers about habitat use.
Changes in fish/invertebrate residency patterns may indicate a project impact.
Collaboration with regional acoustic telemetry researchers allows the most effective deployment of client-supported acoustic receivers to acheive project objectives and capitalize on existing, shared resources.
