Short Description We propose a pilot study to evaluate the use of a mark-resight survey for obtaining estimates of numbers of Snake River chinook salmon redds. If successful, our method would provide a statistically rigorous means of monitoring salmonid populations.
Target Species Snake River Chinook Salmon (Oncorhynchus tshawytscha)

Section 7. Abstract

Abstract

The ability to detect an important trend in numbers of a fish population depends upon obtaining quality estimates of abundance and precision in a cost-efficient manner. Simply relying on a relative index, which is a count that has not been adjusted for undetected objects or individuals, may lead to misleading conclusions because of the unknown magnitude of the sampling bias. A common approach to estimating chinook samon populations is to use an index count of annual numbers of redds. The assumption is that these uncorrected counts represent a constant proportion of true numbers of redds across time, which is unlikely given the nonconstant detection rates of redds due to a myriad of environmental factors affecting their sightability. Further, an index count provides an single number with no measure of precision, i.e., it does not include sampling variation. Therefore, we propose a pilot study to evaluate the applicability, efficiency, and cost-effectiveness of a modified two-sample, Lincoln-Petersen mark-resight estimator for obtaining unbiased and precise abundance estimates of spring/summer chinook salmon redds in the Snake River drainage. If successful, this approach would provide a statistically rigorous means of monitoring salmonid populations by producing an unbiased (or nearly unbiased) estimate of redd nnumbers with a valid measure of precision.
