Tuna capture and release at Wairewa Lake Forsyth

This week whānau from Wairewa, Lake Forsyth have been working hard to ensure tuna, long and short finned eels can complete their lifecycle.

The tuna have been trapped in the lake by a bank of shingle that's built up over time.

The group from the Environmental Board for Wairewa caught about a thousand tuna earlier this week and then released them into the ocean and in the last 24 hours they've finished digging a channel into the bank to release many more.
