After a visit from Dr. Burrows from Loch Lomond Fisheries Luss decided they wanted to do something to help save the almost extinct powan – a fish only found in Loch Lomond and Loch Awe.
Normallly only 0.005% of powan eggs hatch. Pupils were given 100 eggs to look after inside oxygenated tank that were insulated to stop them from getting too warm. The ideal temperature was 5 deg C which they checked 3 times a day.
They learned about the powan’s lifecycle, their predators, what they eat. The projects was a great success and all 100 alevins hatched & were released.
They hope to continue the project every year until powan numbers recover!
