Tuna - tuna heke (downstream migrants)
Once eels become migrants (also known as tuna heke or tuna whakaheke) they stop feeding, and progressively develop the external features that clearly distinguish them from 'feeders'. -
Mining activities
A range of different mining techniques have been developed to obtain these valuable resources -
Water dams
Damming water for urban use, hydro-electric power generation, irrigation, and other industrial and commercial uses. -
Smelt
Smelt have a distinctly forked tail and a strong cucumber smell. -
Water clarity
Water clarity or turbidity is the cloudiness or haziness in a fluid caused by individual small particles (suspended solids). -
Pulp and paper
Wood chips and plant material make pulp that is used to produce paper products. -
Tuna - spawning grounds
All species of freshwater tuna spawn at sea, although the spawning grounds of only four species are known with certainty worldwide. -
Dry stock
Dry stock farming consists predominantly of pasture grazing beef cattle, sheep, and deer for meat, wool, and velvet production. -
What is the proposed activity or industry?
Various industries and land use activities have the potential to impact on water quality and mahinga kai unless properly managed. -
Mitigation and best practice options
Some simple steps to minimise the effects of mining activities on water quality and mahinga kai.
