“…The mean PIC of 0.8860 obtained in this study is a further indication of the genetic variation that is inherent among the clam samples from the different populations. This was lower than the earlier report of Etukudo et al [43], Sastry and Thomas [44] in B. aeruginosa and giant African land snails, respectively.…”

“…The assessment of genetic diversity of clams in the quest for genetic improvement, conservation and contribution to food security cannot be overemphasized. Polymorphic information content (PIC) is a major genetic parameter in assessing genetic diversity [43]. The mean PIC of 0.8860 obtained in this study is a further indication of the genetic variation that is inherent among the clam samples from the different populations.…”

Forty-four (44) samples of clams were obtained from three locations between Cross River and Akwa Ibom States. Genomic DNA was extracted from tissues of the clams using cetyl trimethylammonium bromide (CTAB). Following DNA extraction from the tissues, ultraviolet radiation spectroscopy was used to get the concentration of the DNA isolated from the tissue. From the study, the mean gene diversity obtained was 0.8950 while polymorphic information content was 0.8860. A dendogram of the 44 samples using Weighted Neighbour -Joining (WNJ) procedure clustered them into four major groups. Group I had 78% bootstrap value, group II had 85% bootstrap value, group III had 74% bootstrap value, while group IV had 80% bootstrap. The results of genetic study of the three populations of Egeria radiata showed that they were diverse. Similarly, Original Research Articlethe principal component analysis (PCA) indicated that the four(4) clusters had samples across all the populations of clams studied, showing that there was an active migration of the clams among the three populations leading to a high genetic diversity of the clams. The implication of the results taking together showed that further genotyping should be carried out using other DNA markers that could add further understanding to the genetic diversity of clams.

“…Giant African land snails and periwinkles, both belonging to the phylum Mollusca and class Gastropoda, provide high-quality proteins containing essential amino acids necessary for human body growth, repair, and maintenance [1,2,3,4]. Seafood like periwinkle is particularly valuable due to its rich content of high-quality protein, n-3 polyunsaturated fatty acids, minerals, trace elements, and vitamins, crucial for the growth of the body, brain, and nervous system.…”

“…The fatty acid composition of shell-bearing animals significantly contributes to a healthy diet [6]. Variations in the nutritional content of gastropods depend on factors such as species, sex, feeding habits, age, and seasonal conditions [7,8]. Periwinkles and giant African land snails, among the largest invertebrates after arthropods, exhibit diverse phenotypic traits and habitat preferences [2].…”

The global population surge increases the demand for daily protein requirements, emphasizing the need for cost-effective and readily available protein sources. The study investigated the amino acid, proximate, and mineral compositions of meat powders from four gastropod species (Archachatina marginata, Achatina achatina, Tympanotanus fuscatus, and Pachymelania aurita) procured from Offiong Market in Essien Udim Local Government Area of Akwa Ibom State, Nigeria. The samples were removed from their shells, and washed with deionized water and dilute acid. The meats were then dried at 65 – 70°C for 24 hours, ground into fine powder, and sieved to achieve uniformity in particle size. Amino acid, proximate, and mineral analyses were conducted. Significant differences (p<0.05) were observed in amino acid, proximate, and mineral compositions among the meat powders of the studied gastropod species. Most essential amino acids such as Leucine, histidine, isoleucine, phenylalanine, threonine, methionine, lysine, and valine were present. Proximate analysis revealed high protein and carbohydrate, and low fat and fibre contents among the gastropod species. Mineral analysis indicated high levels of Ca, P, Mg, K, and N, while Zn and Fe were significantly low across all species. The high protein and low fat and fiber contents suggest that gastropod meat powder could be used as additives for food fortification to meet the global demand for protein.
