What is it about?

We incubated kakahi for 1 hr to measure their filter feeding and nutrient excretion rates collected from 6 lakes across the North Island (New Zealand)

Why is it important?

Kakahi excretion rates have not been quantified before but, from international precedents, we know that freshwater mussels can have large effects of the water quality of lakes. Our data allow the effects of various mussel densities on lake nutrient budgets to be investigated.

Perspectives

Kakahi are still quite poorly understood, so it is exciting that fundamental information such as this study is being generated.
