The rockfish tagging crew out at oil platform
Rockfish populations have shown dramatic decline
throughout the southern California Bight over
the last 20 years. Many species of rockfishes
are thought to move very little, which is one of
the reasons they may be so susceptible to
overfishing. Nevertheless, surprisingly little
research has been done to determine home ranges
and site fidelity for many rockfish species.
While many of the natural reefs in California
have been fished quite hard, oil platforms in
the Santa Barbara Channel have functioned as de
facto reefs providing habitat for rockfish.

Collaborating with Dr. Milton Love of the Marine
Science Institute at U.C. Santa Barbara, we have
been tagging rockfishes caught from oil
platforms in the east Santa Barbara Channel with acoustic
transmitters. Acoustic listening stations
are located around the platforms to receive
information about individually tagged rockfishes
tagged with acoustic transmitters.
This project is funded by the
Minerals Management Service (MMS).
