“…It is possible that snail eggs might also be of high nutritive value, though it is not consumed by humans in Nigeria at the present. Okon et al (2013) reported that snail eggs are good sources of protein and basic minerals (K + , Na + , Ca ++ , Fe ++ , Mg ++ and *Corresponding author. E-mail: ibomlawrence@gmail.com.…”

Data from the snail farm of the University of Calabar, Nigeria were collected and utilized to investigate the distribution and gene frequencies of egg shell colour of two ectotypes of Giant African Land Snails (Archachatina marginata var. saturalis), black skinned (BS) × black skinned mating group, and white skinned (WS) × white skinned mating group. The eggs collected were scored for the presence of yellow (Y p), light yellow (L p) and milky white (M p) egg shell colour. The egg shell colour distributions between the two ectotypes (BS × BS and WS × WS) were 46.50 vs. 3.77%, 42.68 vs. 48.11% and 10.83 vs. 48.11% for yellow, light yellow and milky white, respectively. In both ectotypes, the dominant gene for yellow, light yellow and milky white egg shell colour segregated at low frequencies (0.26 vs. 0.02, 0.24 vs. 0.31 and 0.06 vs. 0.31). The lowest value being yellow shell of the white skinned × white skinned mating group with frequency of 0.02, followed by milky white shell of the black skinned × black skinned mating group with frequency of 0.06. These values were much lower than the Mendelian value of 0.75. This is an indication that snails have not been purified through artificial breeding. Estimate of genetic distance between the two ectotypes were 0.060, 0.005 and 0.063 at yellow, light yellow and milky white loci, respectively. This shows that the ectotypes are closely related at the egg shell colour loci.

“…The snail meat Limicolaria flammea contains 46.65% of proteins essential for strengthening nutritional status of malnourished people (Envin et al, 2018). Also, the nutritional value of the flesh of the snail Limicolaria flammea is reflected in its high content of mineral elements, particularly calcium and phosphorus, which are important for strengthening body bone mass and for tooth formation (Okon et al, 2016). Medicinal value of the snail Limicolaria flammea would be reflected in the use of the flesh and shell.…”

The nutritional survey on the snail Limicolaria flammea (Müller, 1774) integrated several aspects and made it possible to understand in particular socio-demographic characteristics of populations surveyed, the knowledge of the snail Limicolaria flammea (according to municipalities visited), vernacular names, consumption parameters, associated uses and the conservation of the meat of this snail. It appears that 55.33% of respondents are women and 44.67% are men. The most important age group is between 20-34 years old. In this age group, 50.12% of people say they consume the snail Limicolaria flammea. Ethnic groups, Akan (55.73%), Krou (35.21%), Mande (6.26%), and foreigners (2.8%) are thus represented in this study and have expressed their opinions on the knowledge and consumption of this animal species. Vernacular names (23 vernacular names) are quite different from each other according to ethnic groups. Consumption parameters showed that the flesh of snail is used for food (65.65%). Also, the shell of snail is used for medical (29.25%), and aesthetic (8.95%). Diseases treated are pain (20.46%) and rheumatism (6.90%). Investigations have shown that 61.70% of consumers keep the snail's flesh fresh, 38.30% of them smoked. The storage time most observed by consumers (65.40%) is 1 to 4 days.

“…Lymnaea stagnalis eggs were approximately 73% protein, 16% lipids, and 11% carbohydrates. Proteins in eggs in the giant African land snail Archachatina marginata were also the most abundant, followed by carbohydrates (Okon et al ). The authors also found high concentrations of ash, sodium, and calcium in eggs.…”

Diet quality has a strong impact on life-history traits, but it is not usually considered as a factor in toxicity tests. The purpose of the present study was to evaluate how diets differing in nutritional content affect sensitivity to cadmium, pyraclostrobin, and tributyltin in Lymnaea stagnalis offspring. Three groups were fed a different diet each: lettuce, high-caloric pellets, or a combination of both. Snails fed pellets and both diets had similar growth; however, snails fed lettuce showed lower growth until the fourth month. Egg masses were collected from adult snails fed each diet and exposed to 3 concentrations of either cadmium, pyraclostrobin, or tributyltin. We quantified time to hatch, hatching success, and the developmental stages of embryos. We measured fecundity in adults and total lipids, carbohydrates, and proteins in adult snails and egg masses. Adult snails fed different diets produced a similar number of egg masses, but the number of eggs per egg mass in snails fed pellets was lower than for snails fed the other 2 diets. We found that adult snails fed pellets had a higher lipid content compared to snails fed the other 2 diets. However, egg masses from parental snails fed pellets did not hatch, including those from the controls. Interestingly, egg masses exposed to the lowest concentration of tributyltin had low hatching success. These observations on offspring performance suggest that there are important diet effects that can strongly influence responses that could be diet- and chemical-dependent.
