Sea run brown trout are available in various locations
and the Rio Grande in Tierra del Fuego is the river that boasts
the best established sea trout runs on the planet.
Brown trout (Salmo trutta
L.) are the second most widely distributed non-native fish introduced
to Patagonia. The first brown trout were stocked in Tierra del Fuego
by John Goodall in 1935. Shipped from Puerto Montt in Chile, 60,000
'salmo trutta' eggs survived the arduous journey to be planted on
the Candelaria and McLennan rivers, both tributaries of the Rio
Grande. These fish eventually found their way to the sea, possibly
attracted by the rich nourishment of the estuary.
These sea-run brown trout now complete the yearly
migratory cycle of salmonids, spawning during the summer months
in freshwater. Salmo trutta remain in the river for a period of
time which ranges between 1 and 4 years until their first migration
to the sea, where they will feed and grow for about 6 months before
their first return to freshwater, weighing approximately 6lbs. Researchers
have found trout which had spawned more than 6 times. A trout which
has completed 4 cycles of returning to freshwater can weigh over
20 lbs. The frequency with which they return to freshwater is also
an indicator that the fish face very few threats. Whilst also providing
a very real example of the benefits of Catch and Release.
Brown trout have been introduced into at least 24
countries outside their native European range (Elliott 1994). They
proliferate throughout their introduced range, often forming sea-run
migratory (sea trout) populations in the southern hemisphere (Frost
and Brown 1967). Ironically, sea trout stocks in their native European
range are in significant decline, largely due to overfishing, aquaculture
activities, and river regulation.
A National law establishes the town of Rio
Grande, in Tierra del Fuego, Argentina, as the Sport Fishing Capital
of Argentina. The road that leads to the Rio Grande has a sign that
makes reference to the honor vested upon this place in the southern
most part of the Patagonia. But the absolute truth is that the Rio
Grande does not need sign or monuments to claim to be what it really
is: The Best Sea Trout River in the World.
The Rio Grande is born in the Chilean Patagonia
at Lynch Lake and after flowing through Lake Blanco it crosses the
border to the Argentinean Patagonia and travels 137 miles to its
meeting with the Atlantic Ocean.
Catch and release is obligatory in the Rio Grande
and the results of this special care are remarkable: in 1983 an
average of 12 sea-runs were captured per week, weighing in at around
6 pounds each. In 2002 that average climbed to 36 fish per week,
tipping the scales at over 11 pounds, although the majority of anglers
that travel down to the Rio Grande can expect to land a 20 pounder
during their stay. The fly fishing record is an outstanding 35.12
