Improve welfare and reduce mortality

Available parameters in each size

Cage distribution

Using Temperature and depth
Detailed behavioural profile

Identify cage distribution with no disturbance to the study animal. A fixed measurement interval or multiple measurement interval can be set, as short as every second to several minutes or even hours.

Long term and short term studies

The long battery life of the loggers facilitates long term as well as short term studies, up to 2-4 years with the largest logger type.

Crowding Events

Using Heart Rate and Temperature

Long or short term heart rate response

These loggers are ideal for long or short term studies looking at heart rate dynamics; studying behaviour, energetics, stress response or environmental challenges.

Suitable for measuring most fish species

It is possible to record extended ECG records for periods where slow heart rates (<20bpm) are expected.

Swimming Performance

Using Activity and Temperature
Overview of changes in activity over time

Measure acceleration derived activity in three dimensions, in addition to temperature. Statistical parameters provide estimation of swimming speed and non-steady swimming in addition to raw data.

Quantify swimming behaviour

Ideal for a variety of studies in swim tunnels, tanks or sea cages, looking at behaviour, swimming, stress response or other swimming physiology.

Welfare Indication Tool

Heart Rate, Activity and Temperature
Identify correlation between heart rate, activity, and temperature

Determine these parameters as proxies for stress in fish and help identify farming practices that can improve welfare.

Overview of physiological response over time

Measure physiological response to environmental variations, including high and low temperature and hypoxia.
