Tens of thousands of eels have been found dead near Lake Ellesmere, also known as Te Waihora, during their yearly migration to the ocean. This event has caused concern among locals who care deeply about the lake and its wildlife.
The eel deaths happened naturally during the tuna heke, the annual journey that eels make from the lake to the sea. This migration is an important part of their life cycle.
Environment Canterbury, the local environmental group, said that while these deaths have happened before, they usually don’t step in unless they’re asked. However, this year they are taking action to help.
To make the eels’ journey safer, ECan is using machinery to lower the sand and gravel barrier between the lake and the sea. This will make it easier for the eels to reach the ocean.
Leigh Griffiths, a manager at ECan, said they are working with local groups like Te Taumutu Rūnanga to carefully plan the work. She explained that although nature often takes care of itself, sometimes it’s helpful to give it a little support.
“There is more migration still to come,” Griffiths said, “so we’re acting now to help the eels continue their journey.”
