Introduction: The V7 acoustic marker is the smallest fish ultrasonic marker in the 69 kHz series of markers. Now Vemco has launched the world's smallest pressure sensor acoustic marker with a diameter of only 7 mm. Acceleration Sensor Acoustic markers can measure the triaxial acceleration of a fish during its movement and then calculate the resultant acceleration. This indicator can be used to measure the various active states of fish (swimming speed, swing frequency, etc.).
There are two modes for the user to choose from, namely swimming mode and tail-float mode. Pressure sensor acceleration markers are used in many aspects of fish behavior research. For example, swamtail acceleration can be used to monitor swimming speed, observe mortality in predatory behavior, and environmental changes (engineering blasting, pollutant leakage, etc.) influence behavior. Can also be used to observe feeding behavior, spawning behavior, differences in day and night behavior, environmental factors (temperature, salinity, dissolved oxygen, waves, etc.) change the behavior of the impact. Tuchuan Science and Technology plans to build China's most professional fish telemetry private laboratories within five years to provide professional hardware and software training, field support, user team training, graduate internships, and undertake scientific research projects. The water weighs only 0.7g. Vemco 69kHz series marked models V7, V8, V9, V13 and V16, basically meet the user's needs for most of the fish.
