Repeatability of the enrichment procedure for triploid C. ariakensis larvae

Abstract
The principal concern for an industry based on aquaculture of triploid C. ariakensis is biosecurity, that is, the assurance against unwanted introduction of the species into the Bay during aquaculture practices. Essentially, this boils down to keeping as many diploids as possible out of the trip lo id population. We set about addressing some questions concerning reducing or eliminating the number of diploids (which on average occur at a rate of 0.1 %). • Can diploids be purged from 4n x 2n batches by size grading? • Is there a difference in the number of diploids eliminated between first and last harvests of eyed larvae? • Can we quantify the degree to which we have "purified" the triploids?
