DFG Will Close Commercial Cabezon
Fishery Season on Oct. 1
The Cab is the one in the middle
The Department of Fish and Game today announced that it
will close the cabezon (Scorpaenichthys marmoratus) commercial fishery
on Oct. 1, 2005 at 12:01 a.m.
DFG is will close the fishery because projections from
landing receipts and dockside tabulation efforts indicate that commercial
fishers will have reached this year's allocation. DFG expects that by
the closure date of Oct. 1 the annual commercial allocation of 59,300
pounds of cabezon will be taken for the 2005 calendar year.
Cabezon is a nearshore fish found mostly in California's
northern and central coastal areas. It is one of the most important
species sought by fishermen in California's live fish fishery. Approximately
50,000 pounds of commercial cabezon have been landed in 2005. Historically,
catch rates increase throughout the summer.
In May 2002, the Fish and Game Commission adopted regulations
authorizing DFG to close either or both of the recreational or commercial
sectors of the cabezon, greenlings, and sheephead fisheries when DFG
projects that fisheries will reach their allowable harvest levels.
Two-month cumulative trip limits for the commercial cabezon, greenlings,
and sheephead fisheries went into effect in 2004 in order to sustain
fisheries throughout the year. The cabezon fishery's two month cumulative
trip limit ranges from a low of 100 pounds of fish in the November/December
period to a high of 900 pounds in the September/October period per nearshore
After a long rebuilding process, the popular dive boat Conception has
been reborn, much of it new, and better than ever.
On March 23, 2005 the 85 foot-long Conception was stolen
from its berth in Santa Barbara, California, rammed into three other
vessels on its way out of the harbor, sinking one, and eventually run
around 50 miles up the coast near Point Arguello.
Although damage was extensive, she was a tough ship and
resilient enough to be dislodged from its rocky resting place and towed
to dry dock in Ventura. There the keel, drive-shafts, props, and bow
was replaced among extensive repairs to the stern and other sections.
Several upgrades have also been made.
The Conception was lowered back into the water August
29th, right on schedule, and has resumed full operation, serving the
Channel Islands along with its Truth Aquatics companions, the Truth
State of the Kelp Report
The first State of the Kelp Report from California Coastkeeper
Alliance details the accomplishments of the first three years of the
Alliances Giant Kelp Restoration Program in the Southern California
Bight. As described in the Report, from 2001 through 2004 project biologists
and almost 200 volunteer scuba divers restored 10,500 square meters
of kelp beds in the Bight and educated 6,825 schoolchildren from Santa
Barbara to San Diego. Thriving kelp canopies have formed from the Kelp
Projects efforts in as little as eight months, and up to 100-fold
increases in fish density and 20 percent increases in fish species diversity
have been observed in the restored areas.
Fully one-fourth of California marine organisms
depend on the kelp forests at some part of their life history,
noted Linda Sheehan, Executive Director of the California Coastkeeper
Alliance. Yet pollution, overfishing, El Niño events and
other man-made and natural threats have reduced the giant kelp canopies
in the Southern California Bight by more than 70 percent over the last
several decades. Intervention through efforts such as the Giant Kelp
Restoration Project is essential to restore these vital marine habitats.
The California Coastkeeper Alliance coordinates and supports
the work of local California Waterkeeper programs from Humboldt Bay
to San Diego in an effort to provide a statewide voice for safeguarding
Californias waters, and its world-renowned coast and ocean, for
the benefit of all Californians and for Californias future. For

Reef Research & Awareness: Ancient
Coral Found Off Hollywood Florida Waters
Coral's discovery may yield 300 years of
"We've got this great repository of environmental
conditions locked into this coral skeleton, sealed up like a mummy,"
said Richard Dodge, dean of Nova Southeastern's Oceanographic Center
and executive director of the university's National Coral Reef Institute.A
huge cone of ancient coral has been discovered in the waters off Hollywood,
offering scientists an unusual opportunity to learn about global warming,
sewage pollution and the decline of the Everglades. Researchers at
Nova Southeastern University have dated the star coral to at least
1694, although they think its origin goes back at least another 50
years. They claim it's the oldest living animal in southeast Florida,
and they plan to study its growth rates and chemical composition for
clues to the effect of human activities on the environment.
Like tree rings and glacier cores, coral skeletons
can yield information about climate and atmospheric conditions
hundreds of years before records began. Such historical data
are critical to scientists trying to study the effect of pollutants
such as carbon dioxide, the leading greenhouse gas.
"We've got this great repository of environmental
conditions locked into this coral skeleton, sealed up like
a mummy," said Richard Dodge, dean of Nova Southeastern's
Oceanographic Center and executive director of the university's
National Coral Reef Institute.
In their initial analysis, they discovered low growth
from the late 1940s through the 1970s, a period when the draining
of the Everglades sent huge amounts of fresh water through the New
River into the ocean. Dodge said this piece of evidence could influence
government decisions over how to restore the Everglades, an initiative
that hasn't given sufficient attention to the potential effect of
fresh water on coral.
The coral off Hollywood, which is 8 feet by 14 feet,
consists of a thin layer of living tissue at the surface of the calcium
cone, which the coral has been building up since the 1600s.
Ken Banks, a reef expert for Broward County's Environmental
Protection Department, saw it 20 feet below the surface while diving
on the first reef from shore. He reported it to scientists at Nova
Southeastern, who set to work with researchers at the University of
Miami and the National Oceanographic and Atmospheric Administration
to sample and study the coral.
They extracted an eight-foot core sample, being careful
to plug the gap and avoid harming the coral. Using a masonry saw,
they sliced it into thin sections, X-rayed them and used the growth
bands to establish the coral's age. Each pair of black-and-white bands
represents one year.
Peter Swart, a professor of marine biology and geophysics
at the University of Miami's Rosenstiel School of Marine and Atmospheric
Science, plans to study the coral's chemical composition for information
on ocean temperatures and the effect of sewage.
There has been a running debate about whether sewage
from outfall pipes and underground disposal wells could be harming
the southeast Florida reefs. Swart will analyze the coral for the
presence of a nitrogen isotope associated with sewage, trying to see
if it appeared in the coral only after people started disposing of
sewage through pipes and wells.
Kevin Helmle, a Ph.D. candidate at Nova Southeastern,
is studying the coral to learn how increased levels of carbon dioxide
in the atmosphere and oceans have affected coral growth. Produced
by automobiles, power plants and various industrial sources, carbon
dioxide is the most widespread of the human-caused gases that trap
the sun's heat, causing global warming.
As carbon dioxide settles in the oceans, it causes the
water to become more acidic, making it difficult for coral to grow.
And as it traps the sun's heat, it raises ocean temperature, which
has been linked to poor growth and an unhealthy condition called coral
Its growth bands vary in thickness, providing initial
indications of which years saw high or low growth. From an initial
analysis, low-growth years appear to coincide with known incidences
of El Niños, the Pacific warming phenomenon.
Other clues to climate will be found in the coral's
chemistry. When water warms, coral incorporates less of the element
strontium in its structure. So as they look for evidence of rising
ocean temperatures over the past 300 years or so, they will seek trends
in the percentage of strontium in the coral.
