摘要: The basket cockle (Clinocardium nuttallii) is a candidate species for aquaculture in the northeast Pacific. aim of current research was to assess feasibility C. nuttallii grow-out, with an emphasis on growth performance and qualities affecting product marketability. In this article, we investigated combined effects culture mode (intertidal off-bottom suspended culture) initial stocking density (1500, 3000, 10 500 21 000 ind m−2) survival during first year grow-out (May through October). intertidal culture, cockles exhibited low poor rates. consistently high (>96%) at all densities tested; condition parameters had highest values 1500 3000 ind m−2. edible portion (meat yield) exceeded 40% whole wet weight densities, occurrences fouled deformed were <1% no commensal observed. Depending minimum harvestable size chosen, proportions constituted from 1.1% 15.2% by October system. depth second are reported companion paper (Dunham et al. issue).
