The future of coral aquaculture is here, and it's an exciting journey! AIMS is leading the way with innovative technologies that are revolutionizing reef restoration efforts. Get ready to dive into a world where automation meets marine biology, and discover how these cutting-edge tools are making a difference.
Coral Spawning Supercharged!
During the annual coral spawning season, AIMS is taking a giant leap forward. As part of the Pilot Deployments Program, we're collaborating with industry and research partners to scale up reef restoration. And at the heart of this mission is coral aquaculture, a vital component that's making waves.
A Million Young Corals and Counting!
The National Sea Simulator (SeaSim) has been a powerhouse, raising over a million young corals and delivering them to the iconic Great Barrier Reef. But that's not all; we're also conducting field trials and working hand-in-hand with industry partners to ensure a comprehensive approach.
Automating the Coral Nursery
You might be wondering, how do we manage such an ambitious task? The answer lies in technology. Several innovations have been developed to automate and enhance coral aquaculture efforts, and we're thrilled to showcase some of these game-changers.
AutoSpawner: The All-in-One Coral Maternity Ward
Imagine a fully automated system that harvests coral eggs and sperm, producing fertilized eggs in abundance with minimal human intervention. That's the AutoSpawner! When corals in the system start spawning, their egg and sperm bundles are carefully skimmed from the water's surface and collected in a fertilization tank. Here, the bundles are mixed to ensure a diverse genetic pool, and the system calculates the optimal time for fertilization based on sperm concentration.
The benefits are remarkable. On busy spawning nights, the AutoSpawner allows us to breed more corals with less human effort, freeing up scientists for other critical tasks. Comparisons with manual methods have shown that the AutoSpawner collects more gametes in less time, with similar fertilization success rates, and significantly reduces labor costs. Just imagine, each AutoSpawner can produce over 7 million fertilized eggs in a single night!
CSLICS: The Ultimate Baby Monitor for Coral Larvae
Now, let's shift our focus to the delicate stage of coral larvae. CSLICS, the Coral Spawn and Larvae Imaging Camera System, is like a high-tech baby monitor for millions of coral larvae. This system estimates the number of free-floating larvae directly in their rearing tanks, which typically hold around half a million larvae each.
CSLICS uses computer vision, a form of AI, to continuously assess the number of larvae in each tank. A network of cameras, each equipped with AI algorithms, feeds data to a central server, ensuring accurate and synchronized monitoring. This technology reduces labor, speeds up the process, and gives us a better chance of detecting any issues early on. With more precise counts, we can distribute corals evenly across experiments, avoid overstocking or understocking, and gain deeper insights into how coral larvae respond to different environmental conditions.
CGRAS: Childcare for Baby Corals
As coral larvae settle and transform into tiny polyps on specially prepared tiles, we need a new camera system to keep an eye on them. Enter CGRAS, the Coral Growout Robotic Assessment System. With a high-resolution submersible camera and a macroscopic lens, CGRAS takes consistent close-up images of the coral babies on their tiles. Currently, it monitors two tanks with 25 tiles each.
Using AI, CGRAS automatically detects the tiny corals, counts them, and tracks their growth over time. This level of monitoring is crucial, as these young corals, initially about 1mm in diameter, need careful attention to ensure their health. Without automation, the labor and time required for thousands of tiles would be overwhelming.
RFID: An ID Card for Baby Corals
To keep track of our baby corals as they journey back to the reef, we use Radio Frequency Identification (RFID). Each coral has its own unique identifier, and as they move from one stage to the next, we scan these RFID transmitters to digitally follow their progress.
For example, each large tile where larvae settle and grow has an RFID chip. These tiles are divided into small squares and inserted into coral seeding devices, which are then attached to metal spikes called spigots for transportation. It's like a coral kebab on a stick!
Each spigot also has an RFID transmitter, allowing us to track the corals during their journey by road and boat to specific reefs. Once deployed, the unique identifier is associated with GPS coordinates, providing a precise record of their new home.
DGS: An AI-Powered Delivery Service for Baby Corals
The Deployment Guidance System (DGS) is the only fully ocean-based tech on our list, combining marine robotics and AI. It's designed to place coral seeding devices in the most promising locations across the reef, where they have the best chance of reaching adulthood.
The DGS is an integrated system, utilizing computer models based on research by reef ecologists. Once in the water, cameras and real-time AI analysis guide the deployment of devices. It provides autonomous vessel guidance and geotagging for future monitoring. While it doesn't replace human expertise, the DGS dramatically speeds up decision-making, automates device deployment, and has the potential to reach even the most remote parts of the reef using autonomous surface vehicles.
And There's More!
These innovations are just the tip of the iceberg. AIMS, in collaboration with industry and research partners, is pushing the boundaries of what's possible in coral aquaculture and reef restoration. With each new season, we're learning, adapting, and refining our techniques. So, stay tuned, as we continue to explore and share the incredible advancements in this field.
