Now that you have eyes underwater with the DTG3 ROV for your net inspections and monitoring of fish health, did you know you can do more than just that?  We’ve compiled some tips and tricks for using Deep Trekker ROV systems in aquaculture.

Active stabilization for precise control

Underwater conditions are in constant motion which is why the DTG3 ROV has been upgraded with active vehicle stabilization. Powered by BRIDGE technology, an intelligent, technology platform from Deep Trekker, enables the vehicle to adapt to changes in water conditions.

Stable camera control

Since the ROV is providing automated control and stability, operators are able to keep the camera focused on their inspection. Easily perform a full 180-degree vertical inspection of netting while holding the ROV’s position.

Adjusting ROV thruster gain

The gain control can be adjusted on the handheld controller to increase or decrease the speed or steering sensitivity of the ROV.  When small precision movements are necessary, reducing the gain can be beneficial. The gain control buttons are the two sets of arrows in the center of the controller. From as low as 1 up to 12, or between 10 -120% power.

Estimating fish sizes

When understanding the size of objects or specimens is critical to your task, the Deep Trekker Laser Scaler is an ideal tool. Used to track fish sizes, the Laser Scaler sends our two laser beams 25 mm apart from above the camera. This allows the user to scale objects within the camera view up to 2 meters away. The lasers track with the camera as it is rotated, allowing for the beams to always be viewed on-screen. With this aimed at a target, the user can simply make a reasonable estimate of the object’s length based on how many times larger it is than the 25mm dot spread.

Integrated Dissolved oxygen (O2) sensor

“Dissolved oxygen control is critical in aquaculture.  The volume of dissolved oxygen contained in water is often a critical parameter in the health and well-being of your livestock.   In general, most fish species will grow and thrive within a DO range of 5-12 mg/L (ppm). However, if levels drop below 4 mg/L they may stop feeding, become stressed and possibly lead to catastrophic fatalities. This series of events can start a chain reaction in a pond aquaculture system that could prove detrimental.” (YSI, 2015).  With the Deep Trekker DTG3 and the integrated dissolved O2 sensor, you can easily monitor water quality conditions and act accordingly, ultimately providing savings and eliminating fish loss.

Deep Trekker offers many water quality sensors.  Have a measurement in mind? Check out our extensive senor options:

  • TEMP/CONDUCTIVITY (SALINITY)
  • RDO
  • PH/ORP
  • CHLOROPHYLL A
  • TURBIDITY
  • AMMONIUM
  • NITRATE
  • CHLORIDE
  • PHYCOCYANIN (BGA-PC)
  • PHYCERYTHRIN (BGA-PE)
  • RHODAMINE WT

Reduce noise pollution 

Did you know that generator noise can be disruptive for some species of fish?  Using your DTG3 – a completely battery powered machine – means you do not need a power source to use the ROV.

Avoid site contamination

You can fully sanitize the Deep Trekker DTG3 with chlorine or other cleaning chemicals, avoiding site contamination and with no effects to the ROV.
