The Archachatina is a genus that includes many species such as A.ventricosa, A.puylaerti, or A.marginata with several sub-species (ovum, suturalis, marginata…). Citation: Ejidike BN, Adewuyi CO (2018) The Giant African Land Snail (GALS) Archachatina marginata Egg and Adult Sizes: Case Study . But now, have you ever seen giant African land snails?! They can measure up to 20cm (8″), and can live up to 10 years! Special reference briefs (National Agricultural Library)’ Beltsville: United State Department of Agriculture (USDA). Snails on T5 had the significantly (p < 0.05) highest value, and the significantly (p > 0.05) least value is obtained in T2. The snails had an average live weight of 437.41 ± 11.56 g. This mating method makes reproduction and population increase very slow for the Archachatina Marginata, unlike the Achatina Achatina. J Anim Vet Adv 6(8):1028–1030, CAS  It is well-known that snails are hermaphroditic, meaning that they are both male and female. (2018), the most important factor influencing the performance of animals under captivity is the quality of diet offered to the animals. However, the gonadosomatic index of snails on herbs and roughage treatment was better than snails on concentrate without leaf meal inclusion. In Cameroon it can be found aestivating under ground during the drier months, having a closed aperture, sealed with a solid, calcareous, white epiphragm.. The environments where the snails thrive are highly contaminated with heavy metals through various anthropogenic activities. 2012). These giant African land snails are in the family Achatinidae. These land snails eat plants at a ferocious state, and so, this behaviour leads to the destruction of crops and damages to homes. (Keep in mind that each of them must have enough space to live and they should not be crammed.) Notify me of follow-up comments by email. E. Afr. Vagina weight of treatments 1 and 4 are statistically similar (p < 0.05) but are significantly (p < 0.05) lower than snails on other treatments. Concentrate diet is essential for optimal reproductive output in snails. J Appl Animal Res 46(1):947–952. Observations on the biology and nutritive value of the African giant snail Archachatina marginata. These are non-exhaustive lists, so feel free to test other things out yourself: Fruits: apple, apricot, banana, grapes, kiwi fruit, mango, melon, peach, pear, raspberry, strawberry, plum, tomato…, Vegetables: lettuce, eggplant, broccoli, carrot, cabbage, zucchini, pumpkin, radish, pepper, mushrooms…, Food supplement: sunflower seeds, pumpkin seeds, hard-boiled egg, raw meat, pinkies, dog/cat food, fish flakes…, A calcium source: cuttlefish bones, crushed oyster shell, eggshell (if you really don’t have anything else to give them). Substrate: Opt for humus/coconut fibres rather than peat (it is too acid and will damage your snails’ shells). The meals were analyzed for their chemical composition as described by Association of official analytical chemists (1990). Google Scholar, Oyeagu CE, Ani AO, Egbu CF, Udeh FU, Omumuabuike JN (2015) Comparative performance of Nera Black and Shaver Brown hen fed self-compounded and commercial layers’ diet. One hundred fifty points of lay snails weighing between 150 and 170 g were randomly allotted to 5 treatment diets with three replicates, ten snails per replicate, designated as treatment 2 (GNCD) which has groundnut cake, treatment 3 (GLLM) has Gliricidia sepium, treatment 4 (MOLM) has Moringa oleifera, and treatment 5 (LLLM) has Leucaena leucocephala leaf meals as protein source in snail diet and a control (treatment 1) (UPWP) fed on roughage (unripe pawpaw and watermelon peel) in a 12-week feed trial. The trend reveals that snails fed with UPWP had the least final weight and weight gain which was accompanied by the highest feed intake across the treatments. 1. Egg hatchability, the fertility of eggs, and average juvenile snails of snails fed on leaf meal-inclusive diets were superior to concentrate-fed snails without leaf meal inclusion; this suggest the beneficial ability of the leaf meals to influence reproduction positively. 5(7):24–32, Nica DV, Filimon MN, Bordean DM, Harmanescu M, Draghici GA, Dragan S (2015) Impact of soil cadmium on land snails: a two-stage exposure approach under semi-field conditions using bioaccumulative and conchological end-points of exposure. (2002). Self-fertilization is impossible though. They include Archachatina marginata, Achatina achatina, Achatina fulica. The average egg laid per snails reveal that snails on leaf meal-inclusive diets (T3–T5) had statistically (p < 0.05) higher value and the significantly (p < 0.05) least values were obtained in snails fed with T1.

The shell changes were not statistically (p > 0.05) influenced by the treatments. Tail "V" Shape. Int. Their original geographic range was western Africa, from the Republic of Côte d’Ivoire (Ivory Coast) to Congo. Privacy The don’ts: pasta, rice, salt, onion, food treated with pesticides (for that you can just peel the veggies and fruits). In Africa, the bushmeat of these snails is so prized that some species are endangered because of the intensive picking in nature. and Blake N.J. (2006). The final weight, weight gain, feed intake, the average egg laid, hatchability, fertility, embryo mortality, and average juvenile snails were significantly (p < 0.05) affected by the diets offered to snails. Incubation is also longer due to bigger eggs and usually takes around four weeks. achatina, Achatina fulica, Archachatina marginata, Archachatina ventricosa, Archachatina degneri and Limicolaria species. The penis of snails on T2–T5 was statistically (p < 0.05) higher than snails on T. Oviduct weight of snails on T5 was significantly (p < 0.05) highest, and other treatments share statistically (p > 0.05) similar values. Incubation period and hatching success was investigated in the African giant land snail—Archachatina marginata. It is easy to feel if you wet your finger and run it over … They can grow up to 20 cm long, and live up to 10 years. The reproductive potentials of the two ectotypes of giant lands snail revealed that Archachatina marginata ovum performed better (P <0.05) The commercial farming of snails on a continuous basis trespassing the dry seasons through good management practices needs assurance of constant feed supply. Snails were kept in wooden cages with the dimension 30 cm × 40 cm × 24 cm (height × length × width). Agricultural Technology Department, Federal Polytechnic Ado Ekiti, Ado Ekiti, Ekiti State, Nigeria, Olatunji Abubakar Jimoh & Micheal Olawale Akinola, You can also search for this author in Out of all the animal protein foods produced and consumed in Nigeria, snail is of importance as it has Your email address will not be published. They will start to hatch after 3 weeks of incubation. (2003), Oyeagu et al. Thompson and Sheldon (2004) also reported that poor nutrition affects snail growth and causes a drop in the reproductive performance; this is evident in the result of laying snails fed roughage/natural plant material (UPWP) which had the least reproductive performance as compared to concentrate GNCD-LLLM-fed snails. Proceedings of the 27th Annual Conference of Nigerian Society of Animal Production; Mar 17–21; Akure, Nigeria: Federal University of Technology. Archachatina marginata, a mollusk, is highly prized as food in Africa and Asia, and is a vector of parasites and defoliators. Archachitina marginata has the ability to live up to 10 years, attaining sexual maturity at 9-10 months under laboratory conditions. The reproductive ability of snails is predicted by the gonadosomatic index; this explains the high gonadosomatic index of snails on leaf meal-based diet accompanied with better reproductive output in laying snails. The land gastropod mollusk scientists refer to a large family … The harvested leaves were shed dried until they were crispy to touch while retaining their greenish coloration. Correspondence to Int J Innov Res Sci Eng Technol 1(1):111–121, Isikwenu JO (2015) Pattern of the effect of different vegetable diets supplemented with concentrate on the growth performance of African giant land snail (Archachatina marginata). Archachatina; Apertural view of a shell of Archachatina marginata: ... Archachatina marginata (Swainson, 1821) - giant West African snail, Cameroon through Zaire. A duo is the minimum, but as they say: the more the merrier! To stay on the safe side, I would recommend the temperature to always stay above 20°C (68 fahrenheit). See in the food section below to find out what you can use. substrat délevage des escargots Archachatina marginata en vu dune amélioration de leur performance de reproduction. Egg hatchability of snails on T4 and T5 were significantly (p < 0.05) higher than snails on treatments 2 and 3. (2018) reported that inclusion of C. pubescens in concentrate ration for snails increased the number of eggs laid, hatchability, and fertility of eggs with a lesser mortality of the embryo. Gonadosomatic index of laying snails fed with roughages and concentrate with different leaf proteins. Terms and Conditions, The final weight of snails on T2 to T5 was statistically (p > 0.05) similar and significantly (p < 0.05) higher than snails on T1. J. Livest. The eggs are yellowish in color and may have dark blotches. Asian Journal Science Technology 6(1):940–946, Oyeagu CE, Udeh FU, Uzochukwu IE, Osita CO, Ugwu SOC, Agugom OH (2018) Effect of dietary Centrosema pubescens leaf meal on growth and reproductive traits of Archachatina marginata snails. Moringa oleifera, Leucaena leucocephala, and Gliricidia sepium leaf meals were obtained from pasture and forage fields within the teaching and research farm premises. The V is a raised, serrated bump. 2018). Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The biggest difference is reproductive strategy where archachatinas have smaller number of very big eggs and thus bigger babies. For the smaller snails, you should slide them gently so they let go. About the size, a vivarium of 50cm (20”) long and 30cm (12”) high and wide will be just right for a pair of Archachatina marginata ovum. Figure 2: Histogram showing weight, length and width of A. marginata eggs collected from different sizes of the adult groups. California Privacy Statement, This way you can hold the shell with your fingers and easily watch your snail coming out of its shell. This research therefore aimed at comparing the effect of roughage and concentrate feed with Moringa oleifera, Leucaena leucocephala, and Gliricidia sepium leaf meal inclusion in snail diet on reproductive attributes of Archachatina marginata. This is important to enhance growth rate and reproduction in snails. The best way to attach it is on the side of your vivarium and not underneath, so they still have a cool place they can bury if needed. Jimoh, O.A., Akinola, M.O.
