IFCB - First year of depoloyment

Press/Media: Research

Description

A system created to detect harmful plankton has analysed around 38 million images in its first year of operation at a fish farm site in Shetland.

The Imaging FlowCytobot (IFCB) uses a combination of lasers and cameras to detect and photograph microscopic, single-celled phytoplankton in the water, before uploading data for specialist analysis, detection and monitoring.

It was deployed by a research team from UHI partners Scottish Association for Marine Science (SAMS) and UHI Shetland, with help from Scottish Sea Farms, which operates the Cole Deep fish farm in Shetland. It is the first time that an IFCB has been deployed at a working fish farm anywhere in Europe.

    DescriptionA system created to detect harmful plankton has analysed around 38 million images in its first year of operation at a fish farm site in Shetland.

    The Imaging FlowCytobot (IFCB) uses a combination of lasers and cameras to detect and photograph microscopic, single-celled phytoplankton in the water, before uploading data for specialist analysis, detection and monitoring.

    It was deployed by a research team from UHI partners Scottish Association for Marine Science (SAMS) and UHI Shetland, with help from Scottish Sea Farms, which operates the Cole Deep fish farm in Shetland. It is the first time that an IFCB has been deployed at a working fish farm anywhere in Europe.

    Phytoplankton are a critical part of the ocean ecosystem, but when they reach large numbers or “blooms” they can create toxins which are dangerous to humans eating shellfish that have absorbed them. The blooms can also be harmful to farmed fish, not only because of the toxins but because they use up dissolved oxygen in the area.

    Early warning of such phytoplankton blooms is therefore crucial for finfish and shellfish farmers.

    The combined research team is using artificial intelligence to train the system to identify different species of phytoplankton at the farm.

    Human taxonomists developed an algorithm to help the instrument identify phytoplankton species. Results are almost instant, compared with traditional methods that can take days to process, from collection of a sample to the identification of potentially harmful algae. The process gives farm managers near real-time information on the types of phytoplankton in the waters surrounding their site.

    The “virtual taxonomist”

    Since entering the water at Cole Deep in spring 2023, the IFCB has photographed phytoplankton around the clock at 20-minute intervals and has already identified trends in the presence of phytoplankton from more than 38 million images taken so far. Thanks to funding from the Sustainable Aquaculture Innovation Centre (SAIC), researchers hope IFCB observations will help them to better understand seasonal trends in harmful phytoplankton blooms.

    Project leader Prof Keith Davidson of SAMS said: “It is notoriously difficult to predict when an algal bloom will occur, given the various environmental factors involved in its formation. The more warning we can give fish and shellfish farmers, the better the chance they have of mitigating the impact.

    “With the IFCB, we have a virtual taxonomist on duty around the clock, identifying potential risks before a scientist has even looked down a microscope.

    “It’s already showing us rapid changes over the courses of a day that we’ve never seen before. Traditional sampling methods use fixatives to preserve the sample for analysis but that can damage the cell. Being able to see live samples shows us the structure of the cell as it’s meant to be.”

    Gregg Arthur, aquaculture knowledge exchange officer at UHI Shetland said: “Deployment of this IFCB device builds on a previous project with Seafood Shetland that was supported by the Shetland Islands Council Coastal Communities Fund. We are excited to learn more about the phytoplankton communities around fish farms, especially when successful aquaculture relies upon understanding our interactions with the natural environment. These devices provide a step-change in our capability and knowledge in the areas where they are deployed as well as an exciting use of AI.”

    Scottish Sea Farms’ Head of Fish Health & Welfare Dr Ralph Bickerdike said: “Already, we’ve been able to glean invaluable information on the real-time composition of harmful algae – information that simply wasn’t available before the IFCB – affording us the opportunity to deploy mitigation measures in the event of a bloom and safeguard the wellbeing of our salmon.”

    SAMS PhD student Gary Groves is developing the AI capability of the IFCB to improve its identification abilities. His work is funded by The Data Lab and the Scottish Government’s Marine Directorate.
