Pomacea canaliculata – Wikipedia

Species of gastropod

Pomacea canaliculata, normally known as the golden apple snail or the channeled apple snail, is a species of big fresh water snail with gills and an operculum, an aquatic gastropod mollusk in the class Ampullariidae, the apple snails. south american in lineage, this species is considered to be in the top 100 of the “ World ‘s Worst Invasive Alien Species “. [ 2 ] It is besides ranked as the 40th worst estrange species in Europe and the worst stranger species of gastropod in Europe. [ 3 ]

distribution [edit ]

The native distribution of P. canaliculata is basically tropical and subtropical, [ 4 ] including Argentina, Bolivia, Paraguay, Uruguay, and Brazil. [ 5 ] The southernmost record for the species is Paso de las Piedras reservoir, south of the Buenos Aires state, Argentina. [ 6 ]

Non-indigenous distribution [edit ]

This species besides occurs in the United States, where the initial introductions were credibly from aquarium publish, aka “ aquarium dump ”. The non-indigenous distribution includes : Lake Wawasee in Kosciusko County, Indiana ; [ 7 ] Langan Park and Three Mile Creek in Mobile, Alabama ; [ 8 ] [ 9 ] a pond bordering the Mobile-Tensaw River Delta in Baldwin County, Alabama ; [ 9 ] Little Wekiva River, Orlando, Florida ; a lake near Jacksonville, Florida ; [ 10 ] Miramar Reservoir in San Diego County, California ; and a pond near Yuma, Arizona. Established populations exist in California and Hawaii. [ 11 ] The species has been found in China since 1981. [ 12 ] Its initial orient of distribution in China was Zhongshan city. [ 13 ] The species has been found in Chile since 2009 with a restrict distribution. [ 14 ] The species has besides been found in the Philippines, Japan, Korea, Taiwan, Vietnam, Cambodia, Laos, Papua New Guinea, parts of Indonesia and Malaysia, Singapore, and Guam. In 1980, the apple snail was introduced to southeast Asia as a food detail and aquarium favored. First, it was introduced to Taiwan, then Japan, then Thailand and the Philippines. rather of catching on, snails were released or escaped and have become a major agrarian pest. [ 15 ] Samples taken 3 December 2020 in Mwea Constituency, Kirinyaga County, Kenya were the inaugural in that area, and indeed the foremost in continental Africa. [ 16 ]

Shell description [edit ]

The shells of these applesnails are ball-shaped in shape. Normal coloration typically includes bands of brown, black, and yellowish-tan ; color patterns are extremely variable. Albino and gold color variations exist. [ 17 ] [ 11 ] The size of the shell is up to 150 millimetres ( 6 in ) in length. [ 11 ]

ecology [edit ]

habitat [edit ]

Pomacea canaliculata egg masses are typically laid on emergent vegetation over freshwater bodies of water. egg masses are typically laid on emergent vegetation over fresh water bodies of water. This species lives in fresh water lake, river, pond and swamp habitats and tolerates a wide range of temperatures. [ 18 ] In natural settings, they rely on grasses and other emergent vegetation growing along the margin of bodies of water to lay their eggs. Where invasive, they can utilize crops such as rice and taro as a substrate for replica. [ 19 ]

Feeding habits [edit ]

Pomacea canaliculata is extremely polyphagous, feeding on vegetal ( primarily macrophytophagous, feeding on floating or submersed higher plants ), detrital, and animal matter. Diet may vary with age, with younger smaller individuals feeding on alga and detritus, and older, bigger ( 15 millimetres ( 19⁄32 in ) and above ) individuals by and by shifting to higher plants. [ 20 ] This species negatively impacts rice and taro department of agriculture cosmopolitan where it has been introduced. [ 11 ]

 in). Eggs of, scale barroom in curium ( in ). In temperate climates, the egg-laying period of this species extends from early spring to early fall. [ 21 ] while in tropical areas reproduction is continuous. The duration of the generative menstruation of P. canaliculata decreases with latitude, to a minimum of six months in the southern limit of its natural distribution. [ 6 ] Adult females oviposit on emergent vegetation at night, but will besides lay their eggs on rocks and manmade surfaces like boats. once laid, the eggs take approximately two weeks to hatch, during which time the bright pink or orange coloration of the eggs fades. [ 22 ] beginning mastermind evidence ( of all animals ), that protease inhibitor from eggs of Pomacea canaliculata interacts as trypsin inhibitor with protease of potential predators, has been reported in 2010. [ 23 ]

Predators [edit ]

The snail kite, Rostrhamus sociabilis, is a predator of this species in South America. The fire ant, Solenopsis geminata, has besides been observed to prey upon this species. [ 24 ]

Parasites [edit ]

approximately 1 % of the Pomacea canaliculata on sale on local markets in Dali City, Yunnan, China were found to be infected with infective Angiostrongylus cantonensis in 2009. [ 25 ]

operate [edit ]

Crude cyclotide extracts from both Oldenlandia affinis and Viola odorata plants showed molluscicidal activeness comparable to the synthetic molluscicide metaldehyde. [ 26 ] Because submerging developing eggs below the water reduces hatching achiever, manipulating the water level in agrarian fields and dammed reservoirs may provide a instrument for controlling invasive populations. [ 22 ]

Human practice [edit ]

This species is comestible. Pomacea canaliculata constitutes one of the three prevailing fresh water snails found in chinese markets. [ 27 ] In China and Southeast Asia, pulmonary tuberculosis of natural or undercooked snails of Pomacea canaliculata and other snails is the primary route of contagion with Angiostrongylus cantonensis causing angiostrongyliasis. [ 25 ] In Isan, Thailand these snails are collected and consumed. They are picked by handwriting or with a hand-net from canals, swamps, ponds, and flooded paddy fields during the showery season. During the dry season when these snails are concealed under dried mud, collectors use a nigger to scrape the mud in order to find them. The snails are normally collected by women and children. [ 28 ] After collection, the snails are cleaned and parboiled. They are then taken out of their shells, cut, and cleaned in salt water system. After rinsing with water, they are assorted with roast rice, dried chili pepper, lime juice, and fish sauce, and then eaten. [ 28 ] special dishes using Pomacea canaliculata are besides produced in China. serve appoint is 田螺塞肉. [ 29 ] Some french restaurants are trying to use Pomacea canaliculata as an alternative to escargot. [ 30 ] After boiling, remove Pomacea canaliculata guts and eggs. Washing alone the mesomorphic body with vinegar will eliminate the smell. As a solution, it can be used as an option to escargot. [ 31 ] Pomacea canaliculata has displaced some of the autochthonal rice field apple snail species in the genus Pila traditionally eaten in Southeast Asia ( including Thailand and the Philippines ) such as Pila ampullacea and Pila pesmei ; a well as the viviparid trapdoor escargot ( Cipangopaludina chinensis ). [ 32 ] [ 33 ] In some paddy fields in Japan, Pomacea canaliulata is used to control weeds by allowing the snail to eat them. however, this method acting runs risk of the snails besides eating youthful rice plants, and of spreading to nearby fields and waterways as an encroaching pest. [ 34 ] [ 35 ] [ 36 ] It is a part of the cosmetic pet trade for fresh water aquarium. [ 37 ]
