Even with such a large stock, direct capture for export has in few cases been profitable. This is because approx. 90% of the catchable sea urchin population in Norway has too low a roe content for direct sales to be economically interesting. Therefore, live storage and feeding is probably the most appropriate way to go to get a profitable industry of a large and little utilized resource.
Catching sea urchins occurs mainly by diving, although diving is hampered by a number of negative features (limited number of divers available, high costs, low regularity due to weather and seasonal conditions, risky). The reason is that there are no methods yet that can compete with diving in terms of efficiency. The use of shell scrapers has also been tried, but it damages sea urchins and is also not good for the bottom environment. The most relevant alternative for diving is the use of a mini submarine (ROV). Experiments with a prototype, developed by Are Hofstad (Seabed Harvester), have given very promising results in terms of capture. When it comes to the sea urchins' survival after capture, the results so far are not as satisfactory. It is therefore of great importance that a further development of ROV for commercial use ensures good survival.
Goals:To further develop a remote-controlled mini submarine (ROV) for efficient and sustainable harvesting of underutilized resources such as sea urchins.
Sub-goal
• To document the catch and survival of sea urchins using ROV.
• To develop a more efficient and profitable catch of sea urchins compared to diving.
