- Abstract
The Guinea razor clam, Solen guineensis (Gray, 1842) was exposed to six levels (400 to 600 mL L-1) of aqueous extracts of decayed sawdust collected from a site close to Okobaba sawmills along the Lagos lagoon and fresh one prepared in the laboratory, to examine the effects of sawdust on its survival. Semi-static bioassay tests were conducted over a 24h to 96h period under controlled laboratory conditions and the exposure media were replaced every 24 hours. The survival rate in response to exposure to both decayed and fresh sawdust extract decreased drastically as concentration and time of exposure increased, with a decrease occurring even at 400 mL L-1. The survival rate was lower in the decayed sawdust extract than with the fresh sawdust extract, but not significant.
