Wilson, William Joseph

Abstract:

The effects of exposure to suspended silt, kaolin and fuller's earth on growth and condition of Pacific oysters, 16 months of age, were studied.

Cluster analysis proved to be a useful statistical method for delineating assemblage boundries and corresponding resident demersal fish components from Georges...
