Objectives and Tasks

Objective Task
1. Determine population abundance and composition of length (age) groups. a. By sport angling techniques, capture white sturgeon between Hells Canyon Dam and Lower Granite Dam pool and mark with PIT tags using standard techniques
. b. Using same angling techniques determine recapture rates of previously marked white sturgeon.
. c. Using mark-recapture procedures determine population estimate for river section in question and compare with previous estimates from the past 25 years
2. Develop and implement strategies to sustain healthy, viable population a. Using information collected in Objective 1, formulate plan to address future management direction that may include additional research needs.

Section 7. Abstract


The white sturgeon Acipenser transmontanus is a resident fish species native to the Snake River drainage and lives in isolated populations segmented by hydroelectric dam construction. The white sturgeon population inhabiting the Hells Canyon reach of the Snake River has been isolated by Hells Canyon (rkm 398) and Lower Granite Dam (rkm 167). This sport fish has been managed under a catch and release sport fishery since 1970, but tribal harvest continues. It is unknown how a healthy, viable sturgeon population appeared prior to man’s interference. This Hells Canyon population has been recognized as one of the most viable in Idaho. We know the population has been impacted by sport harvest prior to 1970 and to some unknown degree because of the dam construction. Coon (1977) described the population before shortly after Hells Canyon and Lower Granite dams began operation. Lukens (1985) suggested the population composition is changing in a positive manner and that juvenile recruit is adequate. NWPPC measure 10.4A.4 recommends that the Bonneville Power Administration fund an evaluation of potential means of rebuilding the sturgeon population in the Snake River between Lower Granite and Hells Canyon dams. Based on previous studies it appears the population is slowly rebuilding itself. This study will describe the population abundance and composition so that comparisons can be made to the previous two studies.. Since 1991 the Idaho Department of Fish and Game Clearwater Region has been annually capturing and marking (by PIT tags and scute removal) all sizes of white sturgeon in this stretch as part of their Sport Fish Restoration program. The ongoing work is not a focused project but is in conjunction with other IDFG investigations. A concerted effort such as this study will allow for total focus on white sturgeon so that adequate sample size can be obtained to make statistically valid decisions. The results of this analysis will provide information for future management direction.
