Abstract
  • The direction of my Marine Resource Management program has been to develop an expertise in a particular area of aquaculture, complemented by a general knowledge of oceanographic principles. Specifically, my area of interest is the culture of marine bivalve molluscs. Prior to entering the MRM program, I had worked with Systemculture Corporation in Hawaii on the research and development of large-scale phytoplankton cultures for the closed system production of the Pacific oyster, Crassostrea gigas. As part of my program at O.S.U., I interned with the Whiskey Creek Oyster Farm in Tillamook, Oregon. This hatchery is among the largest and most efficiently operated hatcheries in the world and has become the primary seed supplier to commercial oyster growers along the west coast of North America. Aquaculture-oriented coursework in my program included Fish and Molluscan Culture, Fish Diseases, and Seafood Processing. In a special projects course under Wilbur Breese at the Marine Science Center, I learned the histological microtechinque for the preparation and interpretation of bivalve gonadal samples and worked with the Pacific weathervane scallop, Patinopecten caurinus, to develop an induced spawning method and investigate early larval development parameters. My courses in Agricultural Finance, Statistics and Microcomputers will be useful in developing and managing an aquacultural business. Given my past experience and current education, I feel I am now qualified to work towards the development of hatchery production technology of aquaculturally desirable bivalve species. This report presents an outline for the development of a bivalve species to hatchery production. In addition, included are aspects of work with induced spawning and larval rearing of the Pacific weathervane scallop, Patinopecten caurinus, a species which shows potential for commercial hatchery production.
