Abstract
Larval and juvenile striped bass Morone saxatilis were mass-marked by oxytetracycline immersion as part of normal hatchery procedures. In 1988, 70% of samples of 1.2 million juveniles treated en route to stocking had a fluorescent mark in their otoliths. In 1989, all samples of 7 million larvae (6–9 d old) treated during transport to grow-out ponds had marked otoliths. Marks were retained for at least 5 and 7 months by larvae and juveniles, respectively. There was no significant difference between the mortality rates of marked and unmarked larvae to 30 d after hatch.Keywords
