Objective
5. Determine
genotypes of Lake Clark sockeye salmon.
A
small finclip reveals the genetic code when analyzed
with microsatellite, allozymes, and mitochodrial DNA techniques.
Answering
questions relating to divergence among populations in genotypic
and phenotypic traits within Bristol Bay is one of the more
difficult problems facing fishery managers. If managers had
a way to rapidly discern among sockeye salmon populations as
they migrate through Bristol Bay they could conceivably close
fisheries to let weak stocks like the Kvichak through. For more
information see the Lake Clark Genetics
Project site.
| Summary
-
Provided
local education and employment opportunities via an
intern program.
-
Established
the framework for long-term monitoring.
-
Collected
lake core samples to examine historic salmon abundance
through sediment layers.
-
Documented
migration corridors and spawning habitats.
-
Preliminary
genetic analysis indicate Lake Clark fish are distinguishable
from other Bristol Bay populations.
