[24] Because submerging developing eggs below the water reduces hatching success, manipulating the water level in agricultural fields and dammed reservoirs may provide a tool for controlling invasive populations. Know your water flow. However, in 1986, it began to damage heavily rice farms in northwestern Luzon. 1993) [22], Approximately 1% of the Pomacea canaliculata on sale on local markets in Dali City, Yunnan, China were found to be infected with pathogenic Angiostrongylus cantonensis in 2009. They are picked by hand or with a hand-net from canals, swamps, ponds, and flooded paddy fields during the rainy season. Snails can also be harvested, cooked and eaten or sold as animal feed. Once the rice plant reaches 30−40 days, it will become thick enough to resist the snail. Golden apple snails eat young and emerging rice plants. Damages rice and taro production by feeding on seedlings; competes with native apple snails and other species (Litsinger et al. The snail’s fast breeding and adaptability, as well as its high protein content, made it an ideal dietary supplement. Originally found throughout the Amazon river basin, it has now spread to Hawaii, Southeast Asia and has been recently reported in Florida. Construct small canals or canalettes (e.g., 15−25 cm wide and 5 cm deep) after the final land preparation. [17], Pomacea canaliculata is extremely polyphagous, feeding on vegetal (primarily macrophytophagous, feeding on floating or submersed higher plants), detrital, and animal matter. The shell of this apple snail species is globose and relatively heavy (especially in older snails). The duration of the reproductive period of P. canaliculata decreases with latitude, to a minimum of six months in the southern limit of its natural distribution. South American in origin, this species is considered to be in the top 100 of the "World's Worst Invasive Alien Species". [25] In China and Southeast Asia, consumption of raw or undercooked snails of Pomacea canaliculata and other snails is the primary route of infection with Angiostrongylus cantonensis causing angiostrongyliasis. [11], The species has been found in China since 1981. [13], The species has been found in Chile since 2009 with a restricted distribution. Plan MR, Saska I, Cagauan AG, Craik DJ"Backbone cyclised peptides from plants show molluscicidal activity against the rice pest Pomacea canaliculata (golden apple snail)." The golden apple snail (Pomacea bridgesii), which is also known under the names apple snail, mystery snail and golden mystery snail, is a large, popular fresh-water snail.

Raise seedlings in low density nursery beds, i.e., less than 100 g seeds per m2 and delay transplanting (e.g., transplant 25−30 day-old seedlings). [21], The snail kite, Rostrhamus sociabilis, is a predator of this species in South America. Blake Wilson, Julian Lucero and Mark Shirley Invasive apple snails — sometimes called giant, golden or channeled apple snails — are native to South America but have been introduced into many regions. The golden apple snail (GAS) was introduced in the Philippines between 1982 and 1984 to supplement sources of food protein of low-income Filipino farmers. Aquatic Invasive Species. The 5 to 6 whorls are separated by a deep, indented suture (hence the name 'canaliculata' or 'channeled'). Following normal fertilizer application rate and schedule, apply fertilizer in 2 cm of water to maximize negative effects on apple snails. In: United States Geological Survey. General Description Apple Snails are also commonly called Mystery Snails, Golden Apple Snails, Golden Snails and Ivory Snails. They are then taken out of their shells, cut, and cleaned in salted water. [23], Crude cyclotide extracts from both Oldenlandia affinis and Viola odorata plants showed molluscicidal activity comparable to the synthetic molluscicide metaldehyde. J Agric Food Chem. Golden apple snails eat young and emerging rice plants. Howells, R. Personal communication. In: United States Geological Survey. Apple snails include species that are the biggest living freshwater snails on Earth. <. They come in several different colours, including white, black, brown and the most common, yellow.

[2] It is also considered as about the 40th the worst alien species in Europe and the worst alien species of gastropod in Europe. [27][28], It is a part of ornamental pet trade for freshwater aquaria. Apple snails are popular aquarium pets because of their attractive appearance and size. The shell opening (aperture) is large and oval to round. Males are known to have a rounder aperture than females. More info about this can be read in the species section of this website. If used, molluscicides should only be used immediately after transplanting or during the seedling establishment phase in direct seeded rice; and only for rice younger than 30 days old. These natives of South America have spread to many other parts of the world, through both deliberate and accidental introductions. They were introduced to Asia, from South America, in the 1980s as potential food for people, but it unfortunately became a major pest of rice. A species of aquatic snail that encompasses the mystery snail, the Golden Inca snail, and many others, the apple snail is an easy addition to any tank. The critical time to manage golden apple snails is during land preparation and crop establishment or planting; specifically, first 10 days after transplanting (DAT), and during the first 21 days after direct wet-seeding. Also many fish will try to nip at the tentacles of the apple snails, but that should not be a problem, as the apple snails will adapt quickly by keeping their tentacles under their shell. Place a wire or woven bamboo screen or mesh bag on the main irrigation water inlet and outlet to prevent snail entry. This damage could lead to more than 50% yield loss. The most widely introduced species of Pomaceain south-east Asia appears to be Pomacea canaliculata (Lamarck, 1822) but at least one other species has also been introduced and is generally confused with Apple snails can live together with most fish without problem, but snail eating fish species should be avoided (obvious). Apple snails have difficulty moving in less than 2 cm of water. Two species, Pomacea canaliculata and Pomacea maculata, commonly known as Golden Apple Snails, are highly invasive and cause damage to rice crops.

They have rounded whorls at the top, with deeply indented sutures. Using a field survey dataset for the invasive golden apple snail P. canaliculata in China, we examined the ASR, quantified its variation across multiple spatial and temporal scales, and analyzed the potential associations between ASR and abiotic/biotic factors. They are distinguished by bright color, unpretentiousness in the care, and are beneficial in the aquarium by eating food left over from the fish, as well as cleaning the walls of algae. J. Bernatis, pers. The shells of Pila are used in traditional ethnomedicine for weakness by Saharia people in Rajasthan, India.. Pila ampullacea and Pila pesmei are some of the rice field snail species traditionally eaten in Thailand that have been displaced by the invasive golden apple snail, Pomacea canaliculata. Species such as the golden apple snail are putting the agricultural sector in the Ebro river basin in quite a predicament. When water is absent, apple snails are able to bury themselves in the mud and hibernate for up to six months. Indiana Department of Natural Resources, 16 June 2005.

Snails are able to spread through irrigation canals, natural water distribution pathways, and during flooding events. [18], This species negatively impacts rice and taro agriculture worldwide where it has been introduced. It has brought about economic losses to aquatic crops in the Philippines that are estimated to be up to USD 1200 million per annum without taking into account the non-crop damage to human health and natural ecosystems. Keep fields drained as much as possible during the vulnerable stages of the rice plant (below 30 days) or transplant 25−30 day old seedlings from low density nursery beds. Lv S., Zhang Y., Steinmann P. &, Zhou X.-N. (2008). This is best done in the morning and afternoon when snails are most active.

Diet may vary with age, with younger smaller individuals feeding on algae and detritus, and older, bigger (15mm and above) individuals later shifting to higher plants. Apple snails have difficulty moving in less than 2 cm of water. Using the Randomized Complete Block Design, the results revealed that there is a significant difference among treatments in terms of body weight. Alleged… Some time later the snails spread to Hawaii, South-West Asia and even Florida. Canalettes facilitate drainage and act as focal points for snails making manual collection or killing easier. Normal coloration typically includes bands of brown, black, and yellowish-tan; color patterns are extremely variable.
