Reproduction in the Eurasian ruffe, Gymnocephalus cernuus

Objectives/Abstract:
To determine the hormonal basis of ruffe oocyte maturation. To determine the hormonal genesis of ruffe sex pheromones. To characterize the response of ruffe to pheromonal signals. To characterize the intergametic signaling and to isolate such signals. To identify the molecules involved with sperm-egg binding during fertilization. To test agents designed to block or interfere with hormonal development, pheromonal signaling at the organismal or cellular level, or gamete binding for their ability to reduce or eliminate ruffe reproduction. Methodology: Maturation inducing steroids (MIS) and sex pheromones will be characterized by standard biochemical methods and their reproductive functions determined by electrophysiological recording and field testing. Biochemical, immunological, microscopical and molecular biology techniques will be used to determine sperm behavior and identify sperm-egg binding molecules.
