Fish and Game stocks land-locked chinook salmon in lakes and reservoirs, and
biologists are asking anglers to help them learn more about these fish in
Anderson Ranch, Lucky Peak and Deadwood reservoirs in southwest Idaho and

are installing signs and drop boxes at those locations and want anglers who
catch a chinook to leave a small tissue sample from the fish for research.
evaluate the performance of these fish, we are asking for anglers to provide
fin clips,” Research Biologist Phil Branigan said. “We’re currently stocking
two types of chinook in reservoirs, sterile and fertile, and we’re trying to
learn which ones are more likely to get caught by anglers.”
are also doing work to determine how the two types of chinook differ in growth
rates. The study is expected to last four to five years. Researchers are
relying on anglers because they are the most cost-effective way of getting fin

process is simple:
Catch a chinook from any of the four waters that are part of the research. Chinook
can be identified by black spots on their backs, black gum lines, and a clipped
Clip a small (about the size of a hole punch) portion of any fin. A sample can
be taken from any size of chinook, and the fish can be harvested or released.
Place the fin clip in an envelope provided at kiosks. Seal the envelope and
keep it dry to avoid spoiling.
Deposit the envelope in the drop box at the kiosks, which can be found at major
access points at the four locations.
chinook in lakes and reservoirs can have double benefits for anglers. They
prevent kokanee from getting overpopulated and undersized, which means larger
kokanee for anglers. At the same time, chinook grow large and provide trophy
fish for anglers to catch.
hopeful that by stocking the best type of chinook, we can ultimately make
fishing better, so we’re optimistic anglers will help us with this project,”

installation at Deadwood will likely be delayed until late spring or early
summer due to high snow pack in the mountains.
