Snail Farming (Heliculture) in india
Humans have been consuming snails for thousands of years. They are very high in proteins, iron and water but are low in Fat. Snail consumption is popular in various countries around the world. Presently, global snail farming or heliciculture industry achieves sales of greater than 12 billion US dollars annually. Fresh water snails have traditionally been used by people as a means of food. A land snail, Iberus alonensis, from Benidorm, Spain, has the earliest record of using snails as food, dating back to the late Pleistocene and Holocene ages. As a human food source, there have been records of snail farming in Europe since Roman times, and in South Asian countries during World War II.
History of snails as food
According to different archaeological surveys and evidences, it is known that ancient humans ate snails as piles of empty snail shells have been recovered from many pre-historic sites. A study revealed that snails used to be an extra food source for Palaeolithic humans in spain. For over 30,000 years, the Iberus aloneness snail has played a role in the gastronomy of Spain. The Benidorm area of Spain is believed to be the first recorded place where humans consumed snails. Around 10,000 years later, people along the Mediterranean coast of Northern Africa, Italy, France, Greece and the Middle East were eating snails. Fresh water snails have traditionally been used by people as a means of food. A land snail, Iberus alonensis, from Benidorm, Spain, has the earliest record of using snails as food, dating back to the late Pleistocene and Holocene ages. As a human food source, there have been records of snail farming in Europe since Roman times, and in South Asian nations during World War II.
Actually, in many European countries, including France, the Netherlands, Belgium and Italy, as well as Latin America, Asia and Africa, snails are considered a delicacy.
Snail caviar is an item of luxury food that has seen rising demand in Europe. The words used for snail farming are Heliculture or Heliciculture, mainly for the consumption of flesh and eggs and for the use of slime for cosmetic purposes.
Major snail consuming countries
The countries in which snail is used in food and various stuffs like, Abalone is a common feature of Chinese cuisine and are called Bao Yu in mandarin. There is other type of snails eaten in China, too and it’s not just the Chinese. The Kiwis, Brits, Americans, and plenty of other people eat it. It is known as Paua in New Zealand and Ormer in the UK. In the Bahamas, conch is eaten raw and is often viewed as an aphrodisiac. In Vietnam, snails are a common pastime food. There are stalls set up that feature a wide variety of snails and apple snails are commonly eaten. In Japan, Turbo snails, whelks and abalone are eaten as sashimi. The Romans popularized snail eating in Europe and it is now a feature of Spanish, Italian, Portuguese, Greek and of course French cuisine. In Korea, whelks are eaten and there is also the dalseulgi (Semisulcospira libertina) and bladder moon snail which are commonly eaten. In Africa, the Giant African Land Snail (Achatina fulica) is eaten and it is a staple of Nigerian cuisine. In the USA, there are conch fritters, boiled periwinkles and a variety of water snails available on the seafood market. Conch were commonly eaten by the aboriginal Americans and in some places, the tribes have left their marks by leaving piles of shells.
Nutritional value and health benefits of Snails
A 3-ounce serving of cooked snails delivers 76 calories with No Cholestrol or sugar as well as 1/3rd of daily Vitamin-E requirement of an adult. It promotes the production of red blood cells that benefits muscle and tissue growth. Additionally, it can provide one half of daily recommended selenium intake. Selenium is an antioxidant mineral that helps in preventing heart diseases and thyroid. Snails also have high mineral content. A single serving of escargot provides 1/6th of daily requirement of iron, 10% of potassium, 1/3rd of phosphorous and 2/3rd of magnesium. Snails also contain a chemical named Tryptophan which is healthy for Brain and is also a good mood booster.
Fresh water snails consumption in India:
Wild species of freshwater snails and calms are widely harvested in underdeveloped nations and eaten by economically and socially challenged societies as a cheap source of protein. India has a tradition of tribal groups eating snails especially from the marine, central and north eastern areas.
In the southern part of India, different classes of snails are eaten by coastal populations, such as snails, clams, oysters and squids. In the states of Bihar, Jharkhand, Maharashtra, West Bengal and the entire northeastern region, including Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, and Tripura, snails (gastropods) are commonly preferred.
Studies have shown that snails are rich in calcium and significant quantities of phosphorus, iron and zinc, especially in species such as Pomacea canaliculata, Pila globosa, etc.
In Tamil Nadu and other coastal areas, freshwater snails belonging to the genus Pila are eaten both for food and for medicinal purposes.
Fresh Water Snails as a traditional food in North Bengal:
During the winter and monsoon seasons, snails are mainly hand-picked from ponds, streams and marshy areas. In addition, snails are obtained during monsoons exclusively from paddy fields.
Women are the majority of the vendors offering freshwater snails.
According to the locals, the number of people selling snails during the monsoon (June to September) and post-monsoon (October to February) seasons is higher than during the summer season (March to May).
Snails are sold in many parts of northeast India as well, not only in the major markets, but also on the roadside and in small markets. Snails are either already packaged in packages of one kilogram or sold loose as needed by the user.
Depending on the species, the average cost of snails during the off-season is about 50 to 100 Indian rupees per cup and 20 to 50 Indian rupees during the monsoon and after-monsoon seasons.
Medicinal uses of Fresh water Snails:
Tribal groups assume that snail intake increases or helps preserve healthy eyesight and proper functioning of the kidneys. In poultry fodder, crushed snail shells are also added as a strong calcium substitute to improve the development of eggs.
There are several other factors as already seen in the global markets where snail’s mucus is used widely in the cosmetic industry as well.
Hence, this field also has lots of areas for research especially the medicinal properties which needs to be reconsider and find out any possibilities which would be a great help in the field of science and medicines.
Snail farming a great option in Indian market:
Freshwater snails are harvested from thousands of wild populations. Sadly, there is no updated list of many Indian freshwater snails species, especially those harvested.
According to Locals opinion stocks of freshwater snails are declining and they also consider this may be due to over-harvesting. Snail faming may be applied in the areas of North Bengal, Assam, the other states of North east as well as the South India to fulfil the needs of local communities.
The snail farming market can flourish more in the Indian market in comparison to other global countries as this would help the tribal communities to expand its traditional food market. In a way this can even help India follow its “Atma Nirbhar” path as well.
In order to determine population trends, long-term population surveys on freshwater snails in the wild must also be conducted. Pollution, dam building and habitat loss endanger freshwater habitats in the north eastern region of India.
So let’s save our traditional food and culture and make our nations independent from all sorts of taboos related especially to Traditional or tribal foods.
Climate and soil required for proper snail cultivation
Snails flourish in mild climate (55-77°F) and high humidity about 75% – 95%. Although most varieties of snails are tolerant to climate but for cultivation purpose high yield is necessary which can be obtained only by providing favourable conditions for their growth and production. If temperature falls below 7°C the snails hibernate. Below 12°C the snails are inactive and blow 10 growth stops. Temperature above 27°C or too much dry conditions result in snails to aestivate. Wind is bad for snails as it speeds up moisture loss and snails must retain moisture to survive. Snails thrive in damp and waterlogged conditions and thus well-drained soil is required. Various researches indicated that 80% of humidity and 80% of water carrying capacity is the most favourable condition. Mist spraying devices and sprayers may be used to maintain the humidity and temperature. Also if the system contains alive vegetation the leaves should be wet. The soil composition should consist of neither too much clay nor too much sand as hard soil is difficult for them to dig and sand has very big pore spaces hence the water is drained excessively. The presence of 20-40% of organic matter stimulates higher growth and cation exchange capacity of calcium as well as magnesium increases. The pH must be around 7 neither acidic nor basic. There should be adequate amount of calcium in the soil so that the primary constituent of shell demand can be completed and growth is not retarded. Addition of limestone to the soil can greatly improvise the calcium content of the soil. Calcium may also be set in tough or feeding fish so that snails can feed into it. Moreover, addition of polyacrylamide to the soil also can improvise soil health. Soil mix may contain peat, clay, compost and CaCo3 The soil may be provided with leaf mould at 7 pH.
Market value in India and export
There are different varieties of snails which are widely consumed by peoples in different parts of India.The north-east states such as ArunachalaPradesh, Mizoram, Nagaland, Sikkim are consumers of snails. Moreover, peoples from parts of west Bengal, Odisha and many restaurants prefer to serve their guests with delicious snail cuisine.Indian Economy is agricultural economy, countries 70% of the population is dependent on Agriculture.Export market is very big for snail in foreign markets. It can greatly contribute to the income of country. There is a great potential for export market in snail cultivation sector.
