Description

Abstract: Recent interest in causes of Dungeness crab (Ca11cer magister) population fluctuations led to a study of temperature and salinity effects on survival and growth of zoeae. Preliminary work developed methods for culturing larvae in flasks with good survival. A comparison of survival of larvae fed two different diets showed the nauplii of the barnacle Balanus glandula and larvae of the bay mussel Mytilus edulis were suitable and unsuitable food organisms, respectively. The optimum ranges of temperature and salinity for laboratory-cultured C. magister zoeae were 10.0-13.9 C and 25-30%0 , respectively. Zoeal survival was not significantly affected by temperatures and salinities approximating ocean ranges of these variables off the Oregon coast during the larval period. The growth rate of C. magister zoeae was directly related to temperature, but salinities that favored survival did not appear to affect the zoeal growth rate.
