Description:
This study was conducted to determine the effet of initial culture stocking density on: (1) post-hatch (larval) dry weight, body length and head-capsule width at 10 and 20 days; (2) time to emergence; (3) number and sex of emergent adults; (4) number of larvae and pupae at test terminatin (day 42 post hatch); and (5) adult dry weight. The results of this experiment suggest that anoptimal egg stocking density of 1.0 egg cm-2 be used with the feeding rate identified. This would ensure uniform larvae at the appropriate developmental stage needed for toxicological research/testing for future culture establishment.
