Behavioral responses of veliger larvae of Crassostrea gigas to leachate from wood treated with copper-chrome-arsenic (CCA): a potential bioassay of sublethal environmental effects of contaminants
This study examined effects upon swimming behavior of larval oysters (Crassostrea gigas) caused by leachates from timber treated against marine borer attack using CCA (copper, chromium and arsenic bound to the lignocellulose of the wood cells). Early veliger stage larvae were observed to avoid a lay...
