Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. To determine how plasma sex steroids and vitellogenin levels vary at different stages of maturation a. Take physiological samples from white sturgeon harvested in the commercial and sport fishery and from white sturgeon sampled by regional agency biologists
. b. Measure the levels of testosterone (T), 11-ketotestosterone (KT), and estradiol (E2), and vitellogenin (Vg) in plasma samples
. c. Assess the stage of development of white sturgeon gonadal samples with histology
2. To distinguish between the sexes of white sturgeon by measuring plasma steroid and vitellogenin levels a. same as Objective 1
3. To determine if the gonadosomatic index, plasma steroid levels, and vitellogenin levels in white sturgeon from impounded portions of the Columbia River differ from those from the unimpounded portions of the river a. same as Objective 1

Section 7. Abstract


The goal of this project is to enhance the management of white sturgeon in the Columbia River. We propose to develop more efficient methods to identify females and males, to develop physiological predictors of maturation, and to determine if physiological differences exist in white sturgeon from impounded and unimpounded portions of the Columbia River that may be useful in explaining variable reproductive success. Such methods may have dramatic effects on making white sturgeon management more effective by: 1) replacing a highly invasive procedure (surgery) with a less-invasive method (blood sampling) for the identification of sex that may decrease potentially damaging stress on females; 2) developing a physiological predictor of maturation that may aid fishery managers in estimating future reproductive success in white sturgeon; and 3) determining if the reduced reproductive success of white sturgeon in certain impounded parts of the Columbia River can be explained by variation in physiological measures. Reproduction in fish consists of an integrated system of tissues and hormones, which direct developmental events necessary for maturation. Once gonadal sex differentiation occurs, ovaries and testes commence secretion of steroids which at the proper age become sexually distinctive in their circulating levels. The specific objectives of this project are to determine if these sexually distinctive patterns of circulatory steroids are consistent enough to replace surgery as the method of choice for identifying sex, to develop endocrine profiles that can be used to model if and when an individual is likely to mature, and to use physiological measures to focus in on potential reproductive problems in white sturgeon found in particular parts of the Columbia River. This work is significant because it will provide a simple tool that can be immediately put to use in sturgeon management. In addition, the technology developed in this project may have broad application in aquaculture and in recovery efforts for endangered wild sturgeon.
