Abstract
Mortality of weir-caught herring 11-23 cm in length and tagged with two sizes of plastic anchor tags was monitored for 21 days in laboratory tanks. Although the presence of tags caused a significant increase in mortality, significant differences were not found between the tag sizes examined. The most important factor determining mortality was fish length, with experimental variability being the next most important factor. Mortality continued throughout the experiment, thus lactic acid accumulation due to stress at the time of capture did not adequately explain the cause of mortality. The experiments suggested that survivorship in the field would be improved by tagging herring no less than 17 cm in length and by minimizing stress and injury during capture and handling.
