Experimental Marking Techniques for Young-of-Year, Hatchery-Reared Striped Bass

Several experiments were tried with varying results using 5 different marking techniques in an attempt to permanently mark juvenile striped bass (Marone saxatilis). Techniques included: immersion staining, dye injection, tetracycline ingestion, streamer tagging, and fin-clipping. From a practical and economical standpoint, 2 methods were satisfactory, at least for short term marking: fin-clipping and tetracycline ingestion. The latter method showed some promise of permanency in mark retention. Other methods were either too ephemeral, too expensive, or caused considerable mortality.
