Computer Vision to Identify Aquatic Macroinvertebrates & Evaluate Water Quality

Featured Image

This blog post features an image of a mayfly: a type of aquatic insect belonging to the order Ephemeroptera. Mayflies are found near freshwater sources, such as rivers and streams, and play an important role in the ecosystem as indicators of water quality. One way to measure water quality is the Ephemeroptera, Plecoptera, and Trichoptera (EPT) index, which uses the diversity and abundance of these aquatic insects, including mayflies, as a metric. High EPT values indicate a healthy ecosystem, while low values may indicate pollution or other issues.

If you know me as the CEO & Co-Founder of Synaptiq, you may be surprised to learn that I studied entomology as an undergraduate and graduate. Entomology, or the scientific study of  insects, appeals to my appreciation for the natural world — an appreciation that today informs my work as head of an AI company

Synaptiq’s purpose is to build a brighter world for future generations with novel applications of machine learning and AI. We believe that “intelligent” technology is powerful because it can accelerate positive change, particularly change that is difficult or cost-prohibitive to achieve manually. As a trained entomologist, I have an eye for “the little things” in life. I spend much of my time considering details that shape our lives while flying “below the radar,” such as solutions to problems that may not be individually notable but are hugely impactful in their totality.

I’m excited to share one such concept with you today: computer vision to identify and count macroinvertebrates (“bugs”) for evaluating water quality. This idea combines my passion for entomology with the AI expertise of our team at Synaptiq.

Accelerating Macroinvertebrate Identification

Aquatic macroinvertebrates (insects, snails, worms, crayfish, and clams) serve as bioindicators of water quality. These organisms have varying levels of tolerance to pollution, so their presence or absence in a waterway provides crucial information about the health of its ecosystem. They are, in a sense, living pollution sensors.

Traditionally, the observation of macroinvertebrates to evaluate water quality is a labor-intensive and time-consuming process. People must carefully collect a sample; then, an expert must painstakingly identify and count each macroinvertebrate present. This second step is particularly challenging, as many macroinvertebrates grow no larger than 1/4 inch in length, and many species closely resemble each other.

Computer vision, a sub-discipline of AI concerned with building software to extract data from visual inputs, allows us to automate and expedite this process. I envision computer vision software that anyone can use to identify aquatic macroinvertebrates with just a simple smartphone app and camera.

This solution would significantly reduce the time and cost associated with traditional methods while also increasing the accuracy and consistency of the results. Furthermore, it would empower “citizen scientists” around the world to monitor their local waters without complicated equipment or extensive training: a feat impossible today.

Helping People & the Planet

The application of computer vision to freshwater biomonitoring is just one example of how technology can change the world in small but significant ways. Synaptiq is always exploring opportunities to improve human and ecological health with AI. We’re excited to pursue the concept discussed in this blog post and are investigating many others.
