Conceptual models

We’ve developed conceptual models for each of our study species.

These models describe our current understanding of the factors influencing their distribution and abundance in the Te Arawa lakes, as well as the relationships between the various factors. Models for each species can be downloaded by clicking on the icons below. A model has not been presented for tuna. Although many of the Te Arawa lakes could support eels, few are able to reach the lake because of natural barriers and thus numbers are low, mostly reflecting deliberate stocking. Therefore any model of factors influencing distribution and abundance of this species will be influenced primarily by stocking rates.
