Abstract
    Mytilus edulis, reared in an Alaskan artificial upwelling system, grew from a shell length of 8·8 to 30·2 mm in 90 days. The phytoplankton densities in the upwelling pond averaged 2·7 x 1010 cells/m3 with the diatoms Bacteriosira and Chaetoceros most prevalent. Temperatures and salinities in the pond averaged 10·5°C and 32·3{per thousand}.In comparison, the mussels which live in the fjord from which the upwelled water was taken require four years to reach 30 mm. Phytoplankton densities and temperature over a mussel bed in this fjord averaged 1·7 x 105 cells/m3 and 11°C. Salinity in the fjord was highly variable and ranged from 3·0 to 24·0{per thousand}during the 90 day period. The phytoplankton species composition in the upwelling pond and the Bay were similar.The results of the experiment indicate that the phytoplankton enhancement caused by artificial upwelling will accelerate the growth of Mytilus edulis in cold water areas.
