There has never been any significant sport fishing for H. rubicundus. However, recently there has been increasing pressure on the population from the commercial salt water aquarium trade.
Largely in response to these pressures, in 1995 H. rubicundus was adopted as the official marine fish of California. California law now protects the fish and prohibits taking for either sport or commercial purposes (Allen, 1991, Geobop, 2002).
US Federal List: no special status
IUCN Red List of Threatened Species: least concern
H. rubicundus feeds primarily on small sessile sponges, bryozoans, and plankton that are found in and around the kelp forests that serve as its home (Allen, 1991; Eschmeyer et al., 1983).
Animal Foods: other marine invertebrates; zooplankton
Primary Diet: carnivore (Eats other marine invertebrates); planktivore
Hypsypops rubicundus (common name: garibaldi) are primarily found off the coast of California. They have a home range from Monterey Bay down to the Baja California peninsula, and around the Channel Islands (Eschmeyer et al., 1983).
Biogeographic Regions: pacific ocean (Native )
Unlike most other members of the damselfish family (Pomacentridae), H. rubicundus lives in cooler temperate waters as opposed to tropical reefs. Their habitats range from the shallow subtidal regions down to depths of approximately 100 feet. H. rubicundus occupies shallow rocky reefs near where the intertidal and subtidal zones meet. Here they swim in and around the kelp forests that are prevalent in this habitat. These kelp forests are a critical habitat element as they provide potential protection from predators, are a source of food for H. rubicundus, and are important for reproductive success (Allen and Robertson, 1994; Nelson, 1994).
Range depth: 35 (high) m.
Habitat Regions: temperate ; saltwater or marine
Aquatic Biomes: reef
Individuals live to upwards of 15 years in their natural environment. This lifespan is much reduced in a captive aquarium environment (Allen, 1991).
H. rubicundus is one of the brightest colored fishes off the southern California coast. Adults are bright orange and the fish gets its common name, garibaldi, from the 19th century Italian leader by the same name whose famous army wore flashy red/orange colors into battle. Juvenile H. rubicundus are distinctivly colored with iridescent blue colored spots along their pectoral and tail fins as well as their lateral lines. This coloration gradually fades as the young reach full maturity at around six inches (Allen, 1991; Sikkel, 1989; Neal, 1993).
Adults grow to a size of approximately 12-14 inches (28-34 cm). H. rubicundus is the largest member of the Pomacentridae (Allen and Robertson, 1994).
Average length: 30 cm.
Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry
Mating System: polygynous
H. rubicundus spawn from mid-March through July. Like other members of the Pomacentridae, it is the male’s responsibility to build and tend the nest. Unlike other members of the family however, the male H. rubicundus spends an inordinate amount of time and energy (approximately an entire month) cleaning and preparing an inviting algal mat more than an inch thick and as large as a tire in circumference. These algal mats are critical to breeding success as research has shown that females prefer to mate with those males which have done the best job of “farming” their mats.
Once a male is successful in attracting a female, he deposits his spermatozoa over her huge clutch of eggs (15,000-80,000). By depositing his sperm over such a large clutch of eggs, the male is able to somewhat conserve his energy expenditures when producing these sperm and is thus able to expend that energy in attracting females and protecting his offspring (Nelson, 1994; Sikkel, 1989).
Breeding season: mid-March through July
Range number of offspring: 15,000 to 80,000.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (External ); oviparous
The male tends the nest and aggressively protects the offspring from predation.
Parental Investment: male parental care
The Garibaldi, known historically also as the Catalina goldfish and marine goldfish and now commonly as the Garibaldi damselfish (Hypsypops rubicundus) is a species of bright orange fish in the damselfish family. It occurs in the subtropical northeastern part of the Pacific Ocean. The English name, Garibaldi, is based on an Italian surname and is a reference to the Italian general and political figure Giuseppe Garibaldi, whose followers often wore a characteristic scarlet or red shirt. As is the case in all damselfish, male Garibaldis aggressively defend the nest site after the female lays eggs.
Adult fish in this species are orange in color. It is the largest member of the damselfish family and can grow up to 38 cm (15 in) in length. Juveniles are more reddish, and have many small iridescent blue spots, which they lose as they become adult. Adult Garibaldis also have a more opaque tail and dorsal fin. The Garibaldi is the official marine state fish of California and is protected in Californian coastal waters.[2]
Garibaldis are found in water from a depth of up to 30 metres (98 ft) depth, usually in association with rock reefs, and typically over rocky sea-bottoms.[3] This species is native to the north-eastern subtropical parts of the Pacific Ocean, ranging from Monterey Bay, California, to Guadalupe Island, Baja California.[3]
Garibaldis feed mainly on invertebrates,[3] which they remove from the rocks. Like most damselfish, adult Garibaldis maintain a home territory.[3] The male clears a sheltered nest site within his territory; the female then deposits eggs within the nest. The male guards the nest area until the eggs hatch, which takes 19–21 days. During the time period that the eggs are developing, the male Garibaldi aggressively tries to keep all other fish away from the (very edible) eggs, and will boldly attack much larger swimming creatures, including humans, to the point of biting divers in order to try to drive them away from the area where the eggs are deposited.
It is peaceful during the juvenile period. But as long as the body is slightly larger, it will show territorial rights to other meek fish and compete with other small fish for territory.[4]
