The cooperative IDFG-NOAA captive broodstock program has provided the safety net preventing the extinction of Snake River sockeye salmon listed as Endangered under the U. S. Endangered Species Act. The NOAA sponsored component has provided more than one million eyed eggs, 159,000 smolts, and six hundred prespawning adults for use in restoration activities. These restoration efforts, coupled with IDFG's production, has resulted in the return of over 320 sea run adults to the Stanley Basin Lakes over the last decade. The steep downward trend toward extinction of the early 1990's has been reversed and the five year average of ocean returns has been increased by over an order of magnitude. It is NOAA-Fisheries opinion that continuation of the cooperative IDFG-NOAA captive broodstock program is essential to prevent extinction and to provide the needed production of Snake River sockeye for future recovery efforts as habitat issues are addressed.
FY 2006 goals and anticipated accomplishments
| Production: # fish released from program, by life stage and species | Produce up to 200,000 fertilized eggs for use in egg box release, fry release, and smolt release programs and up to 500 maturing adults for captive broodstock and captive rearing programs | |
| Incubation: # fertilized eggs into incubation program, by species | Incubate up to 900 fertilized eggs for captive broodstock and captive rearing programs | |
| Incubation: # fry (button-up) produced, by species | Pond up to 900 swimup fry into captive broodstock and captive rearing programs | |
| Rearing: # fish into program (fish ponded), by life stage and species | Pond up to 900 swimup fry into captive broodstock and captive rearing programs | |
| Purpose of production program (S/H/R): S = Supplementation, H = Harvest Augmentation, R = Research | ESA recovery (S) | |
| Broodstock collection: # of fish collected by origin (ad-clip/non-clip) and species | This captive Broodstock program does not collect adults | |
| # of fish by sex (M,F,J), origin (ad-clip/non-clip), and age | Spawn up to 250 adults with an estimated 50:50 male:female ratio that are mostly age 3 and 4. |
The project's primary goal is to provide a safety net captive broodstock population that can be used to sustain Snake River sockeye salmon (Oncorhynchus nerka). The program's secondary goal is to generate fish for use in restoration efforts to speed the rebuilding of this population listed as Endangered under the U. S. Endangered Species Act.
Subbasin planning
How is this project consistent with subbasin plans?
Salmon Subbasin plan Consistency: Aquatics Objective 1B, Strategies 1B2 through 1B3 (pg21): The project is using artificial propagation and innovative techniques to meet the goals identified in Table 6 of the Salmon Subbasin Plan. Aquatic Objective 2A, Strategies 21A, 2A2, 2A5 (pgs 23 and 24): Along with its IDFG partners the project is applying safety net hatchery intervention through continuation of the ongoing captive broodstock programs and developing new smolt release programs to meet interim abundance and delisting goals. These programs provide the gene conservation measures needed to meet the Salmon subbasin plan's goal of preventing the irreversible loss of genetic diversity. The Updated Proposed Action (UPA): The hatchery actions in this document calls for the Action Agencies to continue funding of both existing safety net programs for Snake River Sockeye (pg 4, 66, & 86) listing "the continued operation of the existing safety-net program for Snake River sockeye" as a performance objective. In addition, the document calls for the construction of additional sockeye smolt rearing facilities and funding the production of an additional 150,000 smolts (pg 15 & 86). The 2004 FCRPS BiOp concurs with these UPA's for Snake River Sockeye salmon (pg 6-66& 6-135. In addition, increasing program production by another 150,000 sockeye smolts and developing a second smolt rearing facility is a BiOp conservation recommendation (Section 9.0, pages 9-1 & Appendix F, pg F-8). The Draft Implementation Plan: Implementation language for the UPA can be found on the following pages of the Implementation Plan: Page 3 (Hatchery Actions, and Research, monitoring and evaluation sections). Pg. 5 Hatchery Measures section). Pg. 30: (Section E. Hatchery Actions for Snake River Sockeye). Pg. 32 Near-and long term priorities for Snake River Sockeye. Pg. 54(Addressing sockeye salmon conservation recommendations for the Biological opinion).
How do goals match subbasin plan priorities?
The Salmon Subasin Plan does not provide Aquatic Prioritizations (see section beginning on page 153).
