Abalone Once the captive-bred abalone are old enough, researchers will release them into the wild. When the abalone shell is struck, the tiles slide instead of shattering and the protein stretches to absorb the energy of the blow. Both the Eirolle abalone and white abalone….

The shell of abalones is convex , rounded to oval in shape, and may be highly arched or very flattened. The shell of the majority of species has a small, flat spire and two to three whorls.

The last whorl, known as the body whorl , is auriform , meaning that the shell resembles an ear, giving rise to the common name "ear shell". Haliotis asinina has a somewhat different shape, as it is more elongated and distended.

The shell of Haliotis cracherodii cracherodii is also unusual as it has an ovate form, is imperforate , shows an exserted spire, and has prickly ribs.

A mantle cleft in the shell impresses a groove in the shell, in which are the row of holes characteristic of the genus.

These holes are respiratory apertures for venting water from the gills and for releasing sperm and eggs into the water column.

They make up what is known as the selenizone , which forms as the shell grows. This series of eight to 38 holes is near the anterior margin.

Only a small number is generally open. The older holes are gradually sealed up as the shell grows and new holes form. Each species has a typical number of open holes, between four and 10, in the selenizone.

An abalone has no operculum. The aperture of the shell is very wide and nacreous. The exterior of the shell is striated and dull.

The color of the shell is very variable from species to species, which may reflect the animal's diet. The animal has fimbriated head lobes and side lobes that are fimbriated and cirrated.

The radula has small median teeth, and the lateral teeth are single and beam-like. They have about 70 uncini , with denticulated hooks, the first four very large.

The rounded foot is very large in comparison to most molluscs. The soft body is coiled around the columellar muscle , and its insertion, instead of being on the columella, is on the middle of the inner wall of the shell.

The gills are symmetrical and both well developed. These snails cling solidly with their broad, muscular foot to rocky surfaces at sublittoral depths, although some species such as Haliotis cracherodii used to be common in the intertidal zone.

Abalones reach maturity at a relatively small size. Their fecundity is high and increases with their size, laying from 10, to 11 million eggs at a time.

The spermatozoa are filiform and pointed at one end, and the anterior end is a rounded head. The adults provide no further assistance to the larvae and they are described as lecithotrophic.

The adults are herbivorous and feed with their rhipidoglossan radula on macroalgae , preferring red or brown algae. The haliotid family has a worldwide distribution, along the coastal waters of every continent, except the Pacific coast of South America, the Atlantic coast of North America , the Arctic , and Antarctica.

The shell of the abalone is exceptionally strong and is made of microscopic calcium carbonate tiles stacked like bricks. Between the layers of tiles is a clingy protein substance.

When the abalone shell is struck, the tiles slide instead of shattering and the protein stretches to absorb the energy of the blow.

Material scientists around the world are studying this tiled structure for insight into stronger ceramic products such as body armor.

Abalones are subject to various diseases. Abalone are also severe hemophiliacs as their fluids will not clot in the case of a laceration or puncture wound.

Members of the Spionidae of the polychaetes are known as pests of abalone. The meat foot muscle of abalone is used for food, and the shells of abalone are used as decorative items and as a source of mother of pearl for jewelry, buttons, buckles, and inlay.

Farming of abalone began in the late s and early s in Japan and China. The principal abalone farming regions are China, Taiwan, [22] Japan, and Korea.

After trials in , [26] a commercial "sea ranch" was set up in Flinders Bay , Western Australia to raise abalone. The reef is seeded with young abalone from an onshore hatchery.

The abalone feed on seaweed that has grown naturally on the habitats; with the ecosystem enrichment of the bay also resulting in growing numbers of dhufish, pink snapper, wrasse, Samson fish among other species.

Brad Adams, from the company, has emphasised the similarity to wild abalone and the difference from shore-based aquaculture. Abalones have long been a valuable food source for humans in every area of the world where a species is abundant.

In the Greater China region and among Overseas Chinese communities, abalone is commonly known as bao yu , and sometimes forms part of a Chinese banquet.

However, the availability of commercially farmed abalone has allowed more common consumption of this once rare delicacy. Abalone started to become popular after the Panama—Pacific International Exposition in As abalone became more popular and less common, the prices adjusted accordingly.

This forced the Chinese out of the market and the Japanese perfected diving, with or without gear, to enter the market.

By the time of the exposition, Americans were starting to discover abalone. The popularity of abalone, along with many other fish and shellfish, increased as the exposition exhibited varieties of fish with cooking demonstrations, and a seat dining hall.

In Japan, live and raw abalones are used in awabi sushi, or served steamed, salted, boiled, chopped, or simmered in soy sauce. Tottsuru is mainly enjoyed with sake.

With a recreational abalone licence, the bag limit is 10 per day, with a total possession limit of Scuba diving for abalone is allowed, and has a rich history in Australia.

Scuba diving for abalone in the states of New South Wales and Western Australia is illegal; a free-diving catch limit of two is allowed.

Victoria has had an active abalone fishery since the late s. The state is sectioned into three fishing zones, Eastern, Central and Western, with each fisher required a zone-allocated licence.

Harvesting is performed by divers using surface-supplied air "hookah" systems operating from runabout-style, outboard-powered boats.

While the diver seeks out colonies of abalone amongst the reef beds, the deckhand operates the boat, known as working "live" and stays above where the diver is working.

Bags of abalone pried from the rocks are brought to the surface by the diver or by way of "shot line", where the deckhand drops a weighted rope for the catch bag to be connected then retrieved.

Divers measure each abalone before removing from the reef and the deckhand remeasures each abalone and removes excess weed growth from the shell.

Sport harvesting of red abalone is permitted with a California fishing license and an abalone stamp card. In , the abalone card also came with a set of 24 tags.

This was reduced to 18 abalone per year in , and as of the limit has been reduced to 12, only nine of which may be taken south of Mendocino County.

Legal-size abalone must be tagged immediately. A person may be in possession of only three abalone at any given time.

As of , Abalone season is May to October, excluding July. Transportation of abalone may only legally occur while the abalone is still attached in the shell.

Sale of sport-obtained abalone is illegal, including the shell. Only red abalone may be taken, as black , white , pink , flat , green , and pinto abalone are protected by law.

That year, they extended the moratorium to last through April, An abalone diver is normally equipped with a thick wetsuit , including a hood, bootees , and gloves, and usually also a mask, snorkel , weight belt , abalone iron, and abalone gauge.

Alternatively, the rock picker can feel underneath rocks at low tides for abalone. Abalone are normally found on rocks near food sources such as kelp.

An abalone iron is used to pry the abalone from the rock before it has time to fully clamp down. Divers dive from boats, kayaks, tube floats, or directly off the shore.

Sowerby II , As abalone grow, these holes progressively close-up, with usually only the last four to six holes remaining open when they reach full-size.

Abalone are widely distributed across tropical and temperate coastal areas. They mostly inhabit shallow limestone reefs along the west coast, especially around Perth and near Geraldton.

Female abalone can produce millions of eggs each year. Females release their eggs into the water, where they are fertilised by sperm released by male abalone.

The fertilised eggs hatch into organisms called larvae. Abalone take about four years to reach legal size to collect, which gives females at least two spawning seasons before they can be taken by fishers.

Juveniles feed on microscopic algae. When juveniles reach about 5 mm in length they start feeding on larger species of algae. Abalone have unique features: the shell is round, with two to three spirals.

The last spiral is grown into a large "ear"-like shape, which explains the name 'ear-shell'. The inside of the shell is shiny, from silvery white to green-red mother-of-pearl.

Abalones can start to give birth at a small size. Their fertility is high and increases with size from 10, to 11 million eggs at a time.

Young albalones, called larvae , feed on plankton. The adults eat plants and feed on algae. They like to eat red algae. The shell of the abalone is known for being very strong.

It is made of very tiny calcium carbonate tiles stacked like bricks. Between the layers of tiles is a sticky protein substance.

Allergic skin reactions and asthma attacks can happen when breathing the dust made when these tiles are broken down. The colorful inside part of the abalone shell can be used for decorative inlays , in guitars , for example.

Sport harvesting of red abalone is allowed with a California fishing license and an abalone stamp card. Abalone may only be taken using breath-hold techniques: freediving or shorepicking.

SCUBA diving for abalone is strictly not allowed. Abalone harvesting is not allowed south of the mouth of the San Francisco Bay.

While other species live elsewhere across the world, there are seven abalone species in California: white abalone, black abalone, red abalone, green abalone, pink abalone, pinto abalone, and flat abalone. About The Species Pinto abalone are herbivorous marine snails with one shell and a strong, muscular “foot” that is used to move as well as to grip tightly onto hard surfaces. Pinto abalone range from Southeast Alaska to Baja California, Mexico. Pinto abalone live in kelp beds along well-exposed coasts. The white abalone belongs to a group of plant-eating marine snails that were once common in California. They once numbered in the millions off the California coast, but now they are endangered. Before the time of commercial fisheries, native people along California’s coast ate abalone for thousands of years.
