Shrimp aren’t easy to measure

Shrimp thrive in turbid water. Add in an aeration system, and there’s no way for the human eye or a camera to see below the surface.

See why that’s not a problem for the BRS-1

We developed the BRS-1 to do what nothing else can.

Minnowtech’s subsurface technology enables shrimp farmers to determine the total count and biomass of their shrimp with 95% accuracy, allowing them to optimize their harvests and profits.

How the BRS-1 Works

1. Device Deployment

The BRS-1 device is deployed by a Minnowtech technician.  It provides coverage for an entire pond, no matter the size.

2. Data Collection

BRS-1 sits under the surface of the pond and collects data using sonar. A technician will service the device on a routine basis.

3. Data Analysis

A Minnowtech technician will collect and transfer data to an online portal, giving you real-time access to your data.

Minnowtech Early Access Program

Following successful trials of the BRS-1, we’re moving into the next phase: The Minnowtech Early Access Program.

The Program Includes:
  • One (1) biomass reader system and all required cables.
  • Biomass data readings for (2) two growouts.
Pondside Power and Connectivity
  • Ideally, we are looking for organizations that have both power and wifi available pondside. If there is not a viable power source, Minnowtech can develop a solution to power the devices at an added cost.
Satisfaction Guaranteed
  • We’re so convinced of the power of our technology, Minnowtech will provide a total refund with return of hardware if you are not satisfied with your results at the end of the program.
2X Expanded Coverage Savings
  • A single biomass reader system comprised of six (6) BRS-1 devices has a coverage area of 9-10 hectares. After two (2) grow outs, our machine learning algorithm gets smarter. This allows your system coverage to expand by 2X, reducing the number of devices needed per 9-10 hectares from six (6) devices to just three (3) devices, and cutting the total investment necessary in half.

Impact on a Global Scale

Shrimp farming is a significant pillar of the global food chain, but it’s a tough business. Farmers struggle with high risks and low profits, and existing industry technologies fall short in providing the data they need to make crucial decisions. Farmers are often left guessing about how many shrimp to stock and how much and how often to feed them. And they can miss early signs of devastating events, like disease outbreaks. We want to change that.

About Minnowtech

Founded in 2018 in Baltimore, MD, as a collaborative effort between Dr. Suzan Shahrestani and Early Charm, Minnowtech develops precision aquaculture technologies to maximize aquafarmers’ cultivation efforts using integrated sensor-based systems.

Dr. Shahrestani has a PhD in Fisheries Science and is an expert in applying image analysis, spatial statistics, and population dynamics to the noninvasive assessment of aquatic organisms. Early Charm is a startup studio that co-founds early-stage companies based around intellectual property coming out of universities and federally-funded labs.
