SURROGATE WILD FISHES
• Juveniles reared in artificial environments that emulate specific wild phenotypes
• Spring Chinook and winter steelhead
![Page 6: Developing and delivering surrogate wild Chinook and steelhead Karen Cogliati, David Noakes, Cameron Sharpe, Rob Chitwood, Ryan Couture, and Carl Schreck](https://reader036.vdocuments.net/reader036/viewer/2022062422/56649ee45503460f94bf3a5a/html5/thumbnails/6.jpg)
THE SURROGATE PROJECT Goal:
Rear and deliver surrogate fish to researchers
Objectives:1. Develop rearing protocols that produce more wild-like fish
2. Establish criteria to evaluate the quality and phenotypic accuracy of our surrogates
3. Describe phenotypes of naturally-reared fish to establish target phenotypes
4. Describe phenotypes of hatchery-reared fish to determine the effects of conventional hatchery protocols on phenotypes
![Page 7: Developing and delivering surrogate wild Chinook and steelhead Karen Cogliati, David Noakes, Cameron Sharpe, Rob Chitwood, Ryan Couture, and Carl Schreck](https://reader036.vdocuments.net/reader036/viewer/2022062422/56649ee45503460f94bf3a5a/html5/thumbnails/7.jpg)
• Planning 1-2 years in advance of fish needs• Rear from eyed-egg or green egg stages
• Information required from researchers:• Brood stock• Time of release• Target size at release
STEP 1: COORDINATE WITH RESEARCHERS

LOW-LIPID STARTER DIET
In collaboration with Bozeman Fish Technology Center
Five experimental diet treatments:1. 4-6% lipid
2. 8-9% lipid
3. 11-12% lipid (equal to wild Chinook grower diet)
4. 18-20% lipid from Bozeman
5. 18-20% lipid - commercial Bio-vita starter
