Exploring the beautiful nature of California
Marine Fish: California Scorpionfish
|
|
Fishes are aquatic vertebrates that have fins, gills and
scales. Gills are the part of the respiratory system that
provide surface area for exchanging oxygen and carbon dioxide
under water.
Fish are ectotherms, commonly referred to as
'cold-blooded', meaning their temperature is regulated by the
temperature of their environment. They have a range of diets,
being herbivores, carnivores, or omnivores. Some fish reproduce
by laying eggs, while others reproduce by bearing live young.
California fish species reside in freshwater and coastal/marine
waters. Coastal, or marine fish are an abundant and valuable
resource. However, the ocean's supply is not limitless, and
therefore careful planning and education must be undertaken to
ensure the sustainability of the world's largest food source.

The California scorpionfish is commonly called sculpin although
also called scorpion fish and little poker. A type of rockfish
sculpin are stocky and slightly compressed. The head and mouth
are large, as are the pectoral fins. The color is red to brown,
with dark blotches and spotting over the body and fins.
The sculpin occurs between Uncle Sam Bank, Baja California, and
Santa Cruz, California, with an isolated population in the Gulf
of California. They are caught over hard, rocky bottoms at
depths ranging from just below the surface to 600 feet. Some may
occasionally be taken over sand or mud bottoms..
The diet of the sculpin includes crab, squid, octopus, fishes
and shrimp.
Sculpin first spawn when they are 3 or 4 years, and they may
live 15 years or longer. Spawning takes place from April through
August, and probably occurs at night. The eggs are embedded in
the gelatinous walls of hollow, pear shaped egg-balloons.

The paired egg-balloons, each 5 to 10
inches long are joined at their small ends. The walls of these
"balloons" are about 0.1 inch thick, transparent or greenish in
color, and contain a single layer of eggs. Each egg is about
0.05 inch in diameter. The "balloons" are released at the bottom
of the sea and rise rapidly to the surface. The eggs hatch
within 5 days.
California scorpionfish, known locally as sculpin, are an
important part of the commercial and sport fishery in southern California, especially
within the Los Angeles port complex. In the recreational fishery, they are taken
primarily aboard commercial passenger fishing vessels
Although scorpionfish are most
common around rocky areas and reef areas, they can be caught at
almost every oceanfront pier in Southern
California. Best piers are
Balboa Pier, Newport Pier, Hermosa Beach Pier, the Redondo
Harbor Sportfishing Pier, Green Pleasure Pier in Avalon, and the
Cabrillo Pier.

These fish are delicious to eat and can be fun to catch, but
handle with extreme care. California
scorpionfish are the most
venomous member of the family found in
California.
Its dorsal, pelvic and anal fin spines are associated with venom
glands and are capable of causing an extremely painful wound.
Penetration of the skin by any of these spines may be serious.
If handled in a careless manner and a puncture wound occurs,
there will usually be intense pain and perhaps swelling, which
should subside after a few hours.
Many treatments have been used for sculpin stings, but immersion
of the affected part in very hot water seems to be the most
effective. Multiple punctures can be quite serious, producing
shock, respiratory distress or abnormal heart action and may
require hospitalization of the victim.
