| 1991 |
Identified study areas, brood stocks, and facilities to be used. |
| 1992 |
Began supplementation and monitoring of treatment streams, and monitoring of control streams. |
| 1995 |
Annual Report for 1991-93 Pete King Creek and Clear Creek. USFWS. |

$0 |
|
|
b. Mark hatchery supplementation and general production fish. |
6 |
$2,520 |
|
|
c. PIT tag 750 general hatchery production and 750 supplementation fish. |
6 |
$5,560 |
|
|
d. Release juvenile chinook salmon. |
6 |
$0 |
|
|
e. Estimate parr densities. |
6 |
$5,883 |
|
|
f. PIT tag minimum of 750 naturally produced parr from two treatment streams. |
6 |
$6,804 |
|
|
g. Collect and enumerate emigrating fish. |
6 |
$19,929 |
|
|
h. Count returning adults using weirs, redd walks and carcass surveys. |
6 |
$8,657 |
|
| 2. Monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation. |
a. Collect and enumerate parr, pre smolt and smolt. |
6 |
$20,740 |
|
|
b. Collect tissue samples for DNA analysis. |
6 |
$3,764 |

6 |
$14,250 |
|
|
d. Determine spawner recruitment based on parr and smolt numbers, adult escapement, redd surveys, radio telemetry. |
6 |
$9,300 |
|
| 3. Determine which supplementation strategies (both brood stock and release stage) provide the quickest and highest response in natural production without adverse effects on productivity. |
a. Monitor production (count number of pre smolt, smolt and adults), and productivity (survival, life stage characteristics, straying, genetic composition) of supplemented population. |
6 |
$25,153 |
|
|
b. Spawn local brood stocks with known natural component. |
6 |
$7,272 |
|
|
c. Compare natural production and productivity between first and second generations. |
6 |
$4,908 |
|
| 4. Develop supplementation recommendations. (Long term). |
a. Address risks and benefits in general and specific brood stock and release strategies. |
