Metanephrops Challengeri

M ChallengeriThe New Zealand scampi (aka Metanephrops challengeri) is an endemic deep-sea clawed lobster. They reside on the sea floor at depths anywhere from 140 meters to 640 meters (reported depths). The Asia-Pacific waters contain the majority of the extant Metanephrops species and studies have been conducted regarding their evolution, diet and biology. There has been a breakthrough at the Cawthron Institute (Nelson, New Zealand) and research is progressing in order to make NZ scampi farming a reality.

My first objective for my PhD project was to optimize my methods for the diet assessment – PeerJ article.

The second focus is on using DNA metabarcoding to assess the diet of NZ scampi.

Lastly, I will focus on evaluating the population structure within NZ waters.
