ResumoA simple procedure for transporting live calico scallop, Argopecten gibbus (Linnaeus, 1758), juveniles for grow-out culture is described. The effects of 4 simulated transport periods (9, 16, 20 and 24 h), and subsequent recovery were examined. Success was assessed by survival rate and growth during 2-wk recovery. Survival rate was of 100% for all tested transport periods immediately following transport and following 2-wk recovery. Shell growth averaged 1.76–2.31 mm over the 2-wk period, yielding a growth rate 0.88–1.2 mm.week−1; comparable to average growth rate at same site. There was no significant difference in growth among transport exposure time. Monitored levels of heat shock protein 70 (HSP 70) during manipulation did not indicate any physiologic stress. Successful application of this procedure to a real life 14 h airway transport of another subtropical/tropical scallop species, demonstrates its use for transport of two scallop species juveniles ranging in size from 8–40 mm, without detriment to subsequent survival or growth.
