However, migrations of adult Pacific ocean perch 
appear to be quite limited. For example, Westrheim 
et al. (1974), documented a virtually unexploited 
stock of Pacific ocean perch in Moresby Gully, B.C., 
located immediately north of heavily fished stocks 
in Mitchell’s Gully, also within Queen Charlotte 
Sound (Fig. 1). Pacific ocean perch habitat in Moresby 
Gully is contiguous with that of Mitchell’s Gully at

stocks (Leaman, 1991).
