Abstract |
Our overall aim is to determine the effects of crude oil on the reproductive success of Pacific herring, Clupea harengus pallasi. During the 1982 spawning season we focused on examining effects of oil exposure on attached eggs and free gametes and did some preliminary work on spawning behavior. The purpose of the work with attached eggs and gametes was to determine the effects of realistic exposure to fresh crude oil upon the viability of free gametes, the success of fertilization and the development and hatching success of attached eggs. The preliminary work on spawning behavior was intended to determine whether we could capture herring with a minimum of stress, bring them into spawning condition in the laboratory, and then induce spawning in the laboratory. |
