| dc.description.abstract | It was the aim of this research project to study the growth and reproductive cycles of the Puget Sound Brachyura and Anomura as they are related to oceanographic and environmental conditions. These goals were designed to answer many of the basic questions concerning the local crab population and to serve as a basis for more restricted physiological experimentation dealing with behavior and reproductive cycles. A continuous survey of the intertidal and near-shore crab fauna was made to determine the seasonal change in gonad development, egg production, the time of fertilization, deposition of eggs, and other related-features. As many species of Anomura and Brachyura as could be accommodated were captured and maintained in running sea water aquaria for additional studies of food and feeding habits, ecdysis, copulation, and other phenomena linked to maturity and reproduction. The aim to survey all Brachyura and Anomura in the southern Puget Sound area had to be modified to exclude the hermit crabs .due to the extreme amount of time required for field observation of this group. It has been our goal to correlate reproductive activity of all of these species with annual environmental changes so far as possible and to determine trigger mechanisms involved in the reproductive cycles. Considerable experimentation was attempted along these lines as is discussed herein. | |
