DT-X Software and Applications

Fish population/stock assessment


Determine fish location, distribution, quantity, size, behavior, and biomass. Advanced analysis provides details on individual fish behavior and movement.



Substrate classification / bottom typing


Classify bottom substrates such as rock,

sand, or mud. Used in both freshwater

and marine environments over a wide range of bottom types.





Mapping Aquatic Vegetation 


Detect and measure SAV density, canopy height and geographic distribution. 


The system is effective in both freshwater and marine environments on a number of physiologically diverse submersed aquatic plant types. It operates in littoral areas from the shallows through the entire extent of the photic zone.
