Product Features: to fish or other aquatic animals to achieve a particular target area search, tracking large scale, small-scale two-dimensional or three-dimensional positioning. Behavioral studies in depth information available to aquatic animals like sex, sport and night difference, velocity and direction, and other aspects of migratory ultrasonic telemetry, and precision studies under experimental design can be improved to the internal pressure meter level range. Habitat use home domain (home range) and core use areas (core area) and change the size of the ultrasonic telemetry applications a more fields. It related to rivers, lakes, and oceans of various fish and other aquatic animals. In addition to the home range size range, a number of biologists have studied the aquatic habitat fidelity ultrasonic telemetry. For fish and some of the crustaceans, the habitat includes spawning grounds, feeding grounds and wintering summering courts and other fish in order to survive normal habitat is crucial for each particular period. Ultrasonic telemetry to study habitat facilitate these special times, you can get these special times of habitat location and time of arrival at that location, and length of stay. Fish of various sizes to meet the acoustic tags marked demand for various types of aquatic animals. Length from 12mm to 68mm diameter from 5mm to 16mm frequencies from 51 kHz to 180 kHz coding frequency 69 kHz and 180 kHz sensors: temperature, depth, acceleration of product applications fishery science - habitat distribution - behavior (feeding, spawning, etc.) - invasion and endangered species - migratory routes and time - predator and prey interactions fisheries and aquaculture - productivity measurement - escape monitoring Environmental Assessment - fishway Assessment - reservoirs and dams - offshore oil and gas development impact assessment - Mining and Industry Impact Assessment - Tide to develop impact assessment and development of fisheries protection zone - Marine Protected Areas (MPA) - migration and survival assess product series V series receivers passive acoustic tags active receivers fish 2D / 3D positioning system
