Lethal and Sublethal Effects of High Concentration CO2 on Marine Gastropods

Abstract

There has been great concern over the possible adverse impact of the CO2 leakage from CCS storage places, however, only few reports have been made so far limiting the very issue. In the present study, the lethal and sublethal effects of high concentration CO2 on marine gastropods were investigated. As for test species, adults of a common shellfish in Korean coastal ecosystem, viz. Ruditapes phillippinarum, has been selected as a filter feeding bivalve inhabiting soft substratum, and selected juveniles of an abalone species, viz. Haliotis discus hannai, as an archeogastropoda inhabiting hard substratum. high concentration CO2 on marine gastropods were investigated.
