Acoustic Telemetry: A Tool to Monitor Fish Swimming Behavior in Sea-Cage Aquaculture

Frontiers in Marine Science, 2020
Acoustic telemetry techniques are very useful tools to monitor in detail the swimming behavior and spatial use of fish in artificial rearing environments at individual and group levels.

To hear or not to hear: selective tidal stream transport can interfere with the detectability of migrating silver eels in a Tidal River

Animal Biotelemetry, 2023
Acoustic telemetry provides valuable insights into behavioural patterns of aquatic animals such as downstream migrating European eels (Anguilla anguilla), so called silver eels.

A Novel Framework to Predict Relative Habitat Selection in Aquatic Systems: Applying Machine Learning and Resource Selection Functions to Acoustic Telemetry Data From Multiple Shark Species

Frontiers in Marine Science, 2021
Resource selection functions (RSFs) have been widely applied to animal tracking data to examine relative habitat selection and to help guide management and conservation strategies.

A Markov Chain state transition approach to establishing critical phases for AUV reliability [PDF]

, 2011
The deployment of complex autonomous underwater platforms for marine science comprises a series of sequential steps. Each step is critical to the success of the mission. In this paper we present a state transition approach, in the form of a Markov chain,

High data rate acoustic telemetry [PDF]

The Journal of the Acoustical Society of America, 1981
Four separate acoustic telemetry experiments were conducted during 1979 and 1980 off eastern San Clemente Island in water 1350 to 1450 m deep. In each experiment, telemetry originating near the seafloor was transmitted to receivers aboard a drifting surface ship which remained within 45° from vertically above the telemetry source.

Wireless recording of the calls of Rousettus aegyptiacus and their reproduction using electrostatic transducers [PDF]

, 2008
Bats are capable of imaging their surroundings in great detail using echolocation. To apply similar methods to human engineering systems requires the capability to measure and recreate the signals used, and to understand the processing applied to ...

Acoustic telemetry system as a novel approach for evaluating the effective attraction of fish to artificial reefs

Frontiers in Marine Science, 2023
Due to there being a lack of suitable approaches for evaluating the effectiveness of artificial reefs, two experiments were designed to examine the feasibility of acoustic telemetry, a rapidly developing method for tracking aquatic animals.

Telemetry data of red king crab (Paralithodes camtschaticus) migrations in a north Norwegian fjord

Data in Brief, 2022
Acoustic telemetry allows for high-resolution, long-term tracking of moving animals. Here, we describe data on the movement patterns of 37 adult red king crab (RKC, Paralithodes camtschaticus) obtained by means of acoustic telemetry.

Comparing acoustic and satellite telemetry: an analysis quantifying the space use of Chelonia mydas in Bimini, Bahamas

Royal Society Open Science
Passive acoustic and Argos satellite telemetry are common methods for tracking marine species and are often used similarly to quantify space use. However, data-driven comparisons of these methods and their associated ecological inferences are limited. To
