Animal research data logger DST milli-HRT ACT

temperatureheart rateactivity

Long- or short-term overview of changes in fish or aquatic animal heart rate, activity, and temperature. Minimally invasive, leadless, and simple to implant. The most comprehensive tool on the market to measure individual physiological response of fish. Enables long term aquaculture monitoring, welfare, thermal tolerance, and swimming physiology. Key features Small, size 13 mm x 39.4 mm, 12g, long battery life Leadless, minimally invasive Statistical and raw 3-axis accelerometer data ECG derived heart rates as low as 4 bpm Guaranteed pressure tolerance to 800 m Small and long battery life The DST milli-HRT ACT is a fairly small heart rate, activity and temperature logger that weighs 12g in air, with a diameter of 13 mm and length of 39.5 mm. Long-term heart rate and activity studies are simple to set up. You can expect battery life lasting several months, typically between 1-7.5 months*, depending on sampling frequency and measurement interval. *sampling frequency every 2-20 minutes Published data from several fish species Star-Oddi loggers, available in four sizes, have been used successfully in several publications in various salmonid and other fish species. Fish weighing from approximately 120g up to several kg. The DST milli-HRT ACT is ideal for use in physiological and behavioral research on aquatic animals over 470g. Published studies include thermal tolerance and swim speed tests.
