Establishment of a solid understanding of gold clam (Corbicula fluminea) ecology and direct impacts (ecological, economic, and social) in an Aotearoa-New Zealand context is critical for the effective application of control tools and predictive modelling.
The scope includes:
- Determining reproductive ecology under local conditions to identify vulnerable life-stages, and their timing so that they can be targeted for control
- Understanding the potential impact of the gold clam on benthic species including threatened native species and plankton communities
- Quantifying expected economic costs associated with the clam invasion over time.
Research underway includes:
-
Exploring clam impact on native aquatic plants
The invasive gold clam (Corbicula fluminea) can reach very high population densities, which can harm freshwater ecosystems. -
Using artificial samplers to test the presence and settlement of juvenile gold clams
Filter traps are being used to study the invasive gold clam in the Waikato River. -
Invasive gold clam and kaakahi population survey
Assessing depth specific distribution and relative abundance of gold clam and kākahi at Lakes Maraetai and Karaapiro. -
The impact of the invasive gold clam on water security
Implications for freshwater security, ecosystem health and critical infrastructure.
