DSC_0844 Teviot flathead galaxias (Galaxias 'Teviot') DoC Ranger Daniel Jack measures a fish from one of the very last sites where Teviots still occur. Over the last decade, nearly half the known Teviot populations have been lost. This can be directly linked to the spread of sports fish (trout and brook char), which eat galaxiids; and changes in land use such as stock access to streams, reduction of native vegetation, land development and forest harvesting. The last few populations remain in a few headwater streams small enough to step across in the Teviot River, surrounding Lake Onslow *

DSC_1197 Manuherikia alpine galaxias (Galaxias aff. paucispondylus 'Manuherikia') Freshwater ecologist Dr Richard Allibone, DoC Ranger Daniel Jack and DoC Freshwater Science Advisor Dr Nicholas Dunn, electro-fishing for a highly disjunct population of Alpine galaxias living in the headwaters of the Manuherikia River. This as yet undescribed species, is absent from the remainder of the Clutha River system, apart from an outlier in the Locky River - which flows into Lake Wakatipu. The nearest conspecifics are found to the north, in the Ahuriri River, part of the Waitaki River system. Upper Manuherikia River *
