In one respect, that of the time sequence of return to normal tissue growth after stress, the radular record of row-packing can be more useful than any assessments based on shell-tissue ratios. In field studies of tissue de- growth (Russell-Hunter el a/., 1984), one pond stock of Hclisoma recovered from average degrowth to only over three months in spring. In another stock.
