The tale of a river is often told by the life within it. Understanding
how nature works in the wild can enable and empower those seeking to replicate it.
- Hal Hagen, President Aquatic Alternatives
In the mid eighties, Aquatic Alternatives began
conducting research
into how hatchery raised fish could impact wild populations in a
positive way.
"We began with the observation that there was no clear definition between
what aquaculture was as it related to agriculture, and aquaculture as it
related to wildlife and resource management."
We were keenly aware that hatchery raised fish stocked into public
and private water could reduce the impact on remote wild populations
of trout and provide a wonderful recreational experience for people.
However, blanket stocking of trout throughout the west was also creating
a homogenous population of trout and other potential problems.
This notion was reinforced with agriculture's growing concern that there
was a lack of diversity in wheat and potato stocks throughout the world.
The concern that a virulent pathogen could infect a staple food source
world wide, because of the homogenous nature of these populations, caused
many to search out native,
isolated seed stocks. The hope is that in a
worst-case scenario these plants could have a resistance factor not found
in the more homogenized population.
Aquatic Alternatives started rebuilding its trout research hatchery with
these ideas in mind. We studied spawning channels, resistance to
environmental stressors, gabion baskets and rock matrix habitats, methods
to improve recruitment and whirling disease.
