Christopher G. Lowe, associate professor of marine biology at CSULB, and colleagues
from UC Santa Barbara and San Diego State University received two of 14 grants
from the California Sea Grant program for research projects beginning this year.
Lowe and Jennifer E. Caselle, assistant research biologist at UCSB's Marine
Science Institute, are studying the home ranges and habitat preferences of exploited
near shore reef fishes in the Catalina Marine Science Center Marine Life Refuge.
By attaching acoustic tags to adult ocean whitefish and barred sand bass and
then tracking the fish, Lowe and Caselle will examine the fishes' home ranges
and habitat preferences in the marine life refuge.
"Fish will also be translocated to adjacent areas to test the fidelity
of fishes to their home ranges and to assess the degree to which different species,
for example, kelp bass, sand bass, whitefish and sheephead, will cross expanses
of sand to return to their original home range," Lowe said.
Their goal is to assist the Department of Fish and Game in designing marine
reserves that are large enough and of sufficient quality to ensure the protection
of reproductive adults.
In another study, Lowe and Kevin Hovel, assistant professor of marine biology
at San Diego State University, are examining "Shelter Use, Movement, and
Home Range of Spiny Lobsters in San Diego County."
"California spiny lobsters are an important predator within kelp forests
and rocky shorelines in Southern California. About 500,000 pounds, worth
an estimated $5 million, are landed annually," Lowe said.
One goal of California's Marine Life Protection Act of 1999 is to assess the
home ranges of marine species including "mobile invertebrates" such
as lobsters that are caught by recreational and commercial anglers.
Lowe and Hovel will conduct surveys and sonic tagging of lobsters in the Point
Loma kelp forest, a prime lobster fishing area in San Diego County, to investigate
how the size, type and distribution of sheltering areas influence lobster density,
movement and home range.
Eleven California universities and research facilities were selected to receive
grants for the 14 projects that cover fisheries management, aquaculture, coastal
processes, new marine products, and human impacts on coastal resources.
California Sea Grant, based at the Scripps Institution of Oceanography in La
Jolla, is the largest of 30 university-based programs funded principally by
the National Oceanic and Atmospheric Administration of the U.S. Department of
Commerce.
