Brown Trout in our region are truly WILD trout. All
populations in all local lakes and rivers represent a fully
self-sustaining wild fishery. There is also a significant
sea-run brown trout population which, each spring, re-enters
coastal river mouths and follows the whitebait (like anchovies)
as they migrate upstream to spawn.
Brown Trout Identification.
This is an olive-brown, streamlined fish. It has scattered red or orange
spots that have blue halos. Dorsal and adipose fins accompanied by black
spots. Dark spots are absent in the caudal fin. Teeth are not located on
the midline of tongue. Lateral line scales 120-140. Weighs up to 33lb 10oz
Habitat - It
lives in moderate to high gradient streams and rivers, still waters,
estuaries (and the ocean for extended periods).
This introduced salmonoid (native to Europe and Asia) is a favorite among
anglers. It spawns in autumn and early winter at 55-57 F. The adults eat
crayfish, small fish and a wide variety of insects in both nymph and adult
forms. It has been distributed
throughout New Zealand, and is found in a wide variety of
waters, from ponds, streams and rivers to large lakes and reservoirs.
Brownies spawn in the fall. They build nests (redds) on gravelly
stream bottoms Lake-dwelling fish spawn in tributary streams. After the
eggs are fertilized, the female covers them with fine gravel. The young hatch
the following spring.
They feed on the larval and adult forms of aquatic and
terrestrial insects. Other creatures, such as frogs, mice, crustaceans and fish, are
also consumed. Browns actively feed at night, especially during
Normally a dark olive-brown on the back and sides,
with black spots, orange or red spots with blue halos. Colouration alters substantially
depending on the water they inhabit. In a clear-water river, they are metallic
silver, especially so for juveniles. In the darker tannin-stained lakes, they
are almost black. Transitory colours of river fish migrating into the lakes are
evident, with some fish exhibiting a rich, golden colour. Unlike rainbows and cutthroats, the
tail is usually unspotted and unforked, and there is no reddish side stripe
