Growth and Survival of Mussel Larvae Exposed to Low Levels of Tributyltin and Dibutyltin.

摘要

The effects of low levels of organotins on growth and survival of larvae of the bay mussel Mytilus edulis are relatively unknown. Two experiments were conducted to observe effects of tributyltin (TBT) and dibutyltin (DBT) on larvae 8 days of age through settlement at 33 days of age. The objective of this study was to observe chronic sublethal effects on larval development. Larvae were cultured in a new laboratory assay chamber, sampled twice a week, checked for mortality, and measured for shell growth using a microscope video caliper. Larvae grew to a mean size of 527 micro m at 33 days for controls and to 180 micro m at 200 ug/l DBT.
