Lasers, Drones, and IoT: The Future of Fish

And our top IoT stories of the week!

IoT For All
June 05, 2025

Hello readers,

Welcome to the IoT For All newsletter! This week we’re talking about how IoT and AI are making fish farming more sustainable, how IoT will cut logistics costs in 2025, and more!

Also, an important update to the IoT For All newsletter family: Starting this week, we’ve brought our AI and IoT newsletters together under one roof. That means more insights, fewer signups, and you’re automatically included.

Beeping with the fishes

You might be tempted to think that farming fish has a relatively minor environmentally impact. After all, they already float around out there in the sea. It’s just about adding a little structure to their habitat, and helping them be fruitful and multiply.

In practice, it’s a dicey proposition. Land-based infrastructure (you know, for the humans involved) can damage gentle coastal habitats. And traditional methods can lead to both high water consumption, and a runoff of nutrient-rich wastewater that can throw the surrounding environment for a loop. But IoT (and AI) is helping to perfect a different solution: raise those fish on land.

That’s the (albeit oversimplified) premise behind the Eco Bluehouse designed by smart agriculture company Algofait, which just walked away with the “Sustainability Initiative” Industry Solutions award at last month’s IOT Solutions World Congress in Barcelona. The primary components are the Recirculating Aquaculture System (RAS) and Zero Water Discharge (ZWD) model, which verge on making aquaculture a closed-loop system so it can operate on land without a wealth of waste products or environmental damage.

The Eco Bluehouse (as opposed to a greenhouse) has a variety of IoT-monitored subsystems for air circulation, water filtration, and auto-feeding, so that as many variables as possible are tracked with precision and easy to tweak. That data also gets fed into Algofait’s AI solution, which uses trend data to predict future changes, allowing for autofeeders that adaptively learn, pre-emptive air and water quality alerts, and other operational insights from the company’s “BlueAI.”

Algofait is not the first company to attempt to put IoT to work solving this problem, of course. And competitors have dialed in some fascinatingly different approaches. Norwegian company OptoScale, for instance, has developed a submersible drone called the Bioscope, which hangs out in a fish pen and monitors the situation by taking thousands of photographs, later processed by AI. Another Norwegian company, Cermaq, has taken to delousing salmon and trout with lasers.

Ultimately, while the environmental benefits of this technology are a major boon to the industry and anyone who eats fish, the Eco Bluehouse is also an illustration of the symbiotic relationship between IoT and AI. The more data you generate, the more you can do with it.

Logistics is no longer just about moving goods from Point A to Point B. With the rise of IoT, or the Internet of Things, trucks, ships, and warehouses are becoming smarter and more connected than ever before. From real-time shipment tracking to monitoring cold chain temperatures, IoT is transforming every part of the logistics process. In 2025, these innovations are helping companies deliver faster and operate leaner, saving both time and money

Clinical management refers to the coordinated approach to delivering healthcare services effectively and efficiently. It involves planning, directing, and overseeing the medical and administrative operations within healthcare settings to ensure the best outcomes for patients. Whether it’s managing chronic diseases, improving patient flow, or ensuring timely treatment, clinical management plays a crucial role in the day-to-day functioning of health systems. Here’s how IoT can help.

If you work in cloud security, you’ve more than likely already learned one uncomfortable truth by now: APIs can be both your best friend and your worst enemy. They power a wide range of capabilities across cloud infrastructures but also pose serious security challenges.
