This issue has emerged as another threat to the Arawa lakes with PFAs being found in Lake Rotorua. The close proximity of the airport to the lake has resulted in forever chemicals being detected - raising concerns about mahinga kai sourced from the lake.

eDNA and traditional surveys provide divergent species lists? That's not a flaw—it’s a predictable feature based on what is being measured. 🧬 This paper breaks down the eDNA "inference chain" (shedding, transport, degradation & PCR) to show why eDNA is an inferential tool, not a direct count. 👇

One of the famous stories in Te Arawa history is that of the rangatira Hatupatu, when he attempted to introduce tāmure (snapper) to the Arawa Lakes. The story holds that it was unsuccesful, despite the great effort made to bring live fish inland from the coast. Imagine if snapper were in the lakes🎣😉
