Abstract:: "During the first year of the program successful culture methods were developed for rearing Dungeness crab larvae (Reed 1966). The purpose of the second years work was to define the effects of wide ranges of temperature and salinity on survival and growth of Dungeness crab larvae." (p.1) Includes charts, graphs...

Abstract:: "Construction of a larval rearing system and development of rearing techniques for Dungeness crab larvae were the objectives of the first year's program. Preliminary work involved a literature search, consultation with biologists involved with molluscan and crustacean larval culture, and the design of a rearing system based on the success...

Abstract:: "Culture methods for Dungeness crab larvae and the effects of temperature and salinity on larval survival and growth were covered in previous progress reports (Reed, 1966 and 1967). This report covers studies conducted from July 1,1967, through June 30, 1968 to determine the effects of various laboratory diets and diet...

Creator:: Gaumer, Thomas F. and Oregon. Fish Commission
Abstract:: It is possible that the large fluctuations In annual Dungeness crab landings are caused by displacement of crab larvae by currents. We studied the effects of various environmental factors on crab larvae survival and behavior. Tests were conducted on cultured zoeae and megalopae and on wild megalopae. Our studies showed...

Abstract:: "This report covers studies conducted on Dungeness crab larvae from July 1, 1969, through June 19, 1970. Principal objectives were to determine the following: (1) the effects of crab larval concentration on growth and survival; (2) the effects of light intensity on the swimming behavior of crab larvae; (3) the...
