Section 4. Objectives, Tasks and Schedules

Objectives and Tasks

Objective Task
1. Test the effects of various dosage levels of bovine somatotropin on physiological growth in young white sturgeon. a. Conduct growth trials with 40,80 and 120 mcg somatotropin/g body weight to determine optimal growth conditions.
2. Test the effects of various dosage levels of bovine somatotropin on physiological growth and its relationship to a) the timing of sexual maturity, b) fecundity and c) egg quality in rainbow trout. b. Conduct trout trials to determine optimal growth conditions and carry out the sexual maturity, fecundity and egg quality studies.
3. Investigate the relationship of growth hormone, IGF-I and IGF-II to growth rate and sexual maturity in rainbow trout and white sturgeon. c. Conduct trout trials to determine optimal growth conditions and carry out the sexual maturity, fecundity and egg quality studies.
4. Test the effects of various dosage levels of bovine somatotropin on physiological growth and its relationship to a) the timing of sexual maturity, b) fecundity and c) egg quality in white sturgeon. d. Conduct the necessary animal trials with graded levels of somatotropin, other than that optimal for growth to determine the effect of these levels on sexual maturity fecundity and egg quality.
5. Test the effects of various dosage levels of bovine somatotropin on the periodicity of white sturgeon spawning. e. Carry out the trials to determine the periodicity of spawning.

Section 7. Abstract

Abstract

The overall objective is to develop a bovine somatotropin (bST) treatment regime that will result in the increased reproductive capacity and reduced generation time of female salmonid (rainbow trout) and white sturgeon. We hypothesize that increased growth rate is highly correlated with earlier sexual maturity, as is the case with mammals, and have already demonstrated that the growth of white sturgeon can be increased to 3.5 fold with bST. The general nature of the work will be to induce an accelerated growth rate (of several magnitudes) through the use of sustained-release bST and determine if sexual maturity can be achieved much earlier. Our goal is to develop this application for enhanced fish production through increased reproductive capacity and reduced generation time, as well as elucidate the hormonal relationships underlying the association between growth and sexual maturity in fish. We will work with two different species of Pacific Northwest fish that are representative of diverse physiological traits. White sturgeon will be studied due to their slow growth and delayed timing of sexual maturity, and rainbow trout will serve as a representative of the faster-growing cold water salmonids. Sexual maturity will be determined, egg quantity and quality measurements will be made, and related hormone levels will be studied. This work can be achieved in a reasonable time with rainbow trout, and an assay model will be developed utilizing juvenile, nearly mature, and sexually mature female sturgeon in order to facilitate the timely generation of data necessary for this slower growing species.
