Description
It is often difficult to know just what features of the environment produce population structure in marine species. We can measure currents and observe geologic features that we think might influence their movements, but unless we mark and track individuals we cannot be sure if they travel extensively or are homebodies. In this chapter, we consider the implications to conservation and management of the extent to which individuals move around. We also look at the genetics of a northern Pacific Ocean rockfish species, Pacific ocean perch, to see what we can learn about their movements relative to the oceanographic features they encounter in the Gulf of Alaska.
