Product catalog summary

Overview: This document explores the use of ultra-small implantable physio-loggers for monitoring welfare in aquatic animals, with a focus on Atlantic salmon in aquaculture. These devices track environmental impacts, behavioral patterns, and physiological responses to improve welfare and reduce mortality.

Specifications: The physio-loggers are available in models such as DST nano-T, DST micro-T, DST milli-TD, and DST centi-HRT, each varying in size, weight, battery life, and memory capacity. They measure parameters like temperature, heart rate, and acceleration with high precision.

Procedures: Designed for easy setup and implantation, these loggers facilitate stress-free and accurate measurements. They are suitable for both long-term and short-term studies, with battery life extending from months to years based on the model and measurement intervals.

Norms and Standards: Operating within a temperature range of -1 to +45°C, the devices adhere to specific accuracy and resolution standards. They are applicable to various fish species and can record extended ECG records for slow heart rates.

Recommendations: The document recommends using these loggers to monitor heart rate dynamics, behavior, energetics, stress response, and environmental challenges, aiding in identifying stress indicators and enhancing welfare practices in aquaculture.

Data and Analysis: Data on heart rate and temperature during crowding events and stress tests are included, showing the correlation between physiological responses and environmental conditions. Graphs and tables illustrate the performance and capabilities of different logger models.

Introduction: The document introduces the use of physio-loggers for monitoring welfare indicators in Atlantic salmon, focusing on heart rate, activity, and temperature to improve welfare and reduce mortality in aquaculture.

Specifications: Described as high-performance and compact, the physio-loggers are suitable for long-term and detailed short-term studies, monitoring environmental impact and behavioral patterns in aquatic animals.

Procedures: The document details the use of DST centi-HRT ACT loggers in experiments with Atlantic salmon, measuring heart rate and activity from raw acceleration data, including a critical swim speed test and a stress experiment post-surgical implantation.

Norms and Recommendations: Emphasizing stress-free and accurate measurements, the document highlights the ease of setting up and implanting the devices.

Data Interpretation: Graphs show heart rate and normalized activity over weeks, indicating recovery post-surgical implantation and responses to stress experiments.

Contact Information: Contact details for Star-Oddi, the developer of these loggers, are provided for further information.
