Monterey Bay is uniquely situated between northern and southern Pacific ocean realms. It receives cold oxygenated water from the north and warm more saline water from the south in continual mixing. With these overlapping oceanic regimes occur overlapping biological ones, with creatures present here found to the south but not to the north, and, similarly, creatures found to the north but not to the south of Monterey Bay.
A running list could easily include rockfish of a dozen species (Sebastes), lingcod, salmon, halibut, thresher shark, white sea bass, sand dabs, sand sole, jacksmelt, cabezon, rays, albacore, perches, crabs, and more. Look through the photo gallery to get a good idea of the kinds of fish you can expect to catch.
