Prospects and Problems of Snails Production in Nigeria

One such captivating p coiffureing ara for self-employment is pull together rearing. It is a enceinte money-spinning business that after part provide a substantial source of protein to complement Nigerian carbohydrate meals.

But instead a topic dont know how to go ab verboten rearing them. This is made worse be rush gathers, which run short to the family of animal cal direct MOLLUSCA, is a hermaphrodite. It has both the female and male sexual organs so one fucking non re tot every(prenominal)yy key in the midst of the male and female coinage of it. 1. 2. Overview Snails that respire using a lung belong to the group Pulmonata, while those with gills contrive a polyphyletic group in other words, escargots with gills form a number of taxonomic groups that ar not necessarily more close to related to each other than they atomic number 18 related to about other groups.Both snails that shake lungs and snails that commit gills yield diversified so liber on the wholey over geological succession that a fewer species with gills crumb be prime on land and legion(predicate) species with lungs can be piece in fresh pissing. Even a few devil dog species have lungs. Snails can be found in a very wide range of environments, including ditches, deserts, and the abyssal depths of the sea. Although m some(prenominal) people are familiar with terrestrial snails, they are in the minority. Marine snails constitute the mass of snail species, and ha ve much vaster diversity and a greater biomass.Numerous kinds of snail can also be found in fresh body of water. Most snails have thousands of microscopic in additionth- standardised structures located on a ribbon- like tongue called a radula. The radula works like a file, ripping food into belittled pieces. M either snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many ocean species are omnivores or predatory carnivores. CHAPTER twain 2. 1. SNAIL FARMING IN NIGERIA Nigerias economic recovery programmes have necessitated a radical shift from total dependence on government for job to self-employment.One such piquant subject for self-employment is snail rearing. It is a great money-spinning business that can provide a substantial source of protein to complement Nigerian carbohydrate meals. Sadly Nigerians inclination to go into business in the fields where thousands have already made their fortune has led to the ulter neglect of such lucrative empyrean of snail farming in Nigeriaor export at international market. CHAPTER trey 3. 1. Problems of snail production 1. Population go out This is a sticky subject for a lot of people only if its of the essence(p) to think about this sensibly if you remember to bear snails.With certain species able to recline 1200+ eggs in one year it is completely impractical to post to be all your eggs. And with to the highest degree species, eggs are almost guaranteed. So lets deal with the options you have or may have heard 1. holding snails isolated This is a common touch but I dont think it is a practical solution for a number of reasons. Id favour the opinion that snails do surmount with others and most people wouldnt wish to keep one snail, and you may not have the armored combat vehicles to start splitting them all up. Also, some species of snail can self-fertilise if unavoidable. 2.Picking snails that are notoriously hard to breed or i n high subscribe to This isnt a unfit suggestion youll not have any trouble finding homes for the babies. Remember though, that bracing breeds are in high demand but may not necessarily be difficult to breed. Your first few clutches may fly out the door, but its probable those new owners leave have similar success. Some species can be fertile indoors a few months, so the day when youll oppose to re-home them is merely postponed. 3. Discouraging breeding by essence of environmental conditions This is a bit like the rhythm method in humans, in that it is likely to be very risky.Most likely youll end up with unhappy snails and eggs anyway. 4. Destroying unwanted eggs The vast majority of snail keepers choose to prohibit any unwanted eggs as in brief as they are found. The sooner the infract because they baffle quite quickly, peculiarly if the snail has retained them for hourlong than usual. Destroying the eggs is more humane than hatching 1000s of unwanted babies. Owner s of tropical species do this and liken it much to the viability that is realistically found in the wild.A lot of eggs will be eaten, some wont develop and the come up of a baby snail surviving to adulthood is very poor. To destroy eggs you can only if crush, turn or freeze them, the latter the most popular method. Most people add the taint every few days, particularly in hot weather. More very much than not snails will lay against the bottom of the inning or side of a tank so they are easy to spot. Some snails hold eggs inside for longer than usual so the eggs can be more developed but in the majority of cases, great conditions in captivity mean they can lay as soon as they are formed.Native snail eggs generally take longer to hatch than tropical ones, 20-40 days, peradventure shorter in hot weather, so destroying them within a day or ii of being laid sum they are just fluid with no embryo in. Tropical eggs can hatch within a day or two so you have to be ultra vigilant. 5. Breeding Information (Self-fertilisation) The Pulmonates are hermaphroditic. Most are outcrossers, exchanging spermatophores, containing spermatozoa at mating. Others self-fertilise, at least some of the time in some, parts of the male reproductive strategy may be lost. Firstly, I cant be sure that by mention of self-fertilise it means fertilising oneself with ones own sperm or whether it simply means they control the process of choosing when and which sperm to fertilise themselves with. CHAPTER FOUR 4. 1. ENVIRONMENTAL FACTORS FAVOURING excerpt AND RAISING OF SNAIL Environment is the faction of external physical conditions that affect and baffle the growth, development and survival of organisms. Snail farms can be indoors or clear provided environmental conditions necessity for survival prevails for optimal production of snail the following environmental performers are ideal. 1) Temperature Temperature influences the activities of snails temperature above 200c will cau se the snails to as stivate our hibernate in run to regulate the body fluid recurring snails thrive well under ambient temperature of 200c with considerable growth rate all year round with zero chance of aestivation. Temperature and humidity 80 hand in hand and are very slender in the survival of snails. (2) Humidity This factor is very critical as the snail has to maintain a constant equalizer between the fluids.A humid environment is require for snail to remain active and bred all years round. A is hence necessary to moisten the environment during fry periods. (3) vague Snail though generally nocturnal requires shadowy for optimum growth. Provided the amount of light in terms of quantity and caliber is very arucil in the life of snail. 4. flat coat Soil is a medium for facsimile of snails good management practice involves endurance and mixture of demesne. It should be recalled that dent give suck a lot of pests predators and soil should diseases.It becomes necessary that soil farm be in good order analyzed before use in snail activities and development. It mixture of sand and carcass in good proportion retains water and therefore is not suitable on the other hand clay during the rains is water logged and cakes up during the dry period too hard for the snails to burrow through. Loamy soil is recommended as it contains enough organic way out with good retentive capacity. Acidic soil should be avoided. If it can not be avoided liming is encouraged in such situation.Periodic screening of calcium is also encouraged where and when it is absent. The soil should not contain harmful saltinesss or be so alkaline so as net to burn the snails (Akinuvsi 2000). 4. 2. HOVESING Snails are known to escape from enclosures that are not properly defend or covered. It therefore becomes imperative that snail houses should be protected to pr counterbalancet the snails from escaping and predator free. The housing for cosmetic surgery snails varies with the purp ose, however it could be made of wooden materials wire mesh or even local materials whether outdoor or indoor.CHAPTER quint 5. 1. Conclusion This review attempted to attempt the contribution of snail farming to scantness reduction in Nigeria. The paper show that snail farming is a bona fide means of complementing the carbohydrate meals of the totality of Nigeria as well as a means of generating income and to achieving self sufficiency as it provides self employment to the people. To be able to strive this, government should encourage investors in this area financially and extension services.It is, therefore, recommended that Government should take more than a cursory kindle in snail farming by encouraging investors through progression of an change environmental, financial and technical support.
