“…The variation of crude protein content in the cultured crab samples might be due to the differences in protein contents and the number of ingredients used for feed formulation, the approximate quality of the compound feed, and the amount of feed intake by the crabs. Our result was higher than the protein content obtained by Akpang and Oscar [23] in Thais coronota, while the protein content of C. armatum fed animal-based diet was relatively higher than that reported by Akpang and Oscar [23] in Callinectes amnicola and Typanosomas fuscatus. The 41.04% protein value recorded in T. fuscatus from a tropical creek, which was reported by Job and Ekanem [24], appeared to be significantly higher than that reported in this study.…”

Background Preliminary research on the domestication of mangrove fisheries resources, especially those with high aquaculture potential, is mandatory as a requirement for aquaculture activities to ensure sustainability. This study evaluated the possible domestication, growth performance, and length-weight relationship of Land crab (Cardisoma armatum) crablets reared for twelve (12) weeks and fed complete (control), animal, and plant-based compounded diets, as well as the influence of formulated feeds on the biochemical profile of the domesticated crabs. Sixty (60) crablets of mixed sizes and sexes weighing 22–24 g was stocked at the rate of ten C. armatum crabs in three treatments and three replicate units and cultured for 12 weeks. The crab tissues after the completion of the feeding trial were manually detached from their bodies, processed, and transported to the laboratory for biochemical analysis. Result The result of the biochemical contents of the C. armatum samples showed that the choice of ingredients utilized in feed formulation influenced the nutritional and mineral compositions. The final body weights were 46.10±0.10 g for crabs fed a complete diet, 38.92±0.15 g for a plant-based diet, and 47.84±0.18 g for an animal-based diet. The results obtained for the length-weight relationship of the crab samples showed a negative allometric growth pattern (b<3). However, the result of the condition factor for females, males, and combined sexes was greater than 1. The results obtained in the preliminary study showed that C. armatum can be successfully domesticated if properly managed. Conclusion Cardisoma armatum fed with an animal-based compound diet had better overall growth performance and converted their feed better. Further study on the reproduction and domestication of C. armatum in captivity is hereby recommended to increase food security and sustainability.

“…The highest percentage of mean crude protein was found in T. fuscatus at 3.23 ± 0.70% and showed a significant difference (P < 0.05), and the lowest percentage of crude protein was found in T. coronata at 2.18 ± 1.06%. Akpan and Oscar 18 recorded a protein content of 22.52% for T. fuscatus from the Calabar River, which was proportionally higher than the 3.23% obtained in this study. Similarly, the result obtained for protein content in this study was lower than the values of 46.51%, 51.30%, and 58.45% recorded in blended marrows of T. fuscatus , P. aurita , and T. coronata , respectively, by Inyang et al 19 .…”

“…In some parts of Nigeria, specifically the coastal areas such as Cross River and Port Harcourt, Periwinkle, especially T. fuscatus, commands an extremely high market value 18 . Awareness of the nutritional composition, accessibility, and low cost of periwinkle meat is the major reason for high market demand.…”

Periwinkle shells of Tympanotonus fuscatus, Pachymelania aurita, and Thais coronata were analyzed for their proximate composition, nutritionally significant minerals, trypsin inhibitors, and carotenoids. The mean values obtained were compared using an ANOVA test. The results showed that T. fuscatus had the highest mean moisture content of 0.96 ± 0.14% and a mean value of 0.49 ± 0.13% for crude fibre but was not significantly different (P > 0.05) from P. auritus. The crude protein and fibre content of T. fuscatus was significantly higher (P < 0.05) than other periwinkle samples. T. coronata had the highest mean total ash content and was significantly different (p < 0.05) from other periwinkle samples. T. fuscatus had the highest mean value for Mg (0.32 ± 0.03 mg/kg) and differed significantly (P < 0.05). The mean Ca content of P. aurita was not significantly different (P > 0.05) from that of T. coronata. The mean values of CaCO3 in T. fuscatus, P. aurita, and T. coronata were 57.20 ± 2.46, 59.50 ± 3.23, and 62.36 ± 1.56 (mg/kg), respectively. T. coronata was significantly different (P < 0.05) from other periwinkle samples. The mean values of carotenoids in T. fuscatus, P. aurita, and T. coronata were 7.17 ± 2.14, 18.00 ± 5.27, and 11.20 ± 3.60 (mg/kg), respectively, and P. aurita was significantly different (P < 0.05) from other periwinkle samples. T. fuscatus and P. aurita had shells with significant amounts of trypsin inhibitor (23.30 ± 4.50 mg/kg and 22.90 ± 14.10 mg/kg, respectively), making them less suitable for livestock feed. In contrast, T. coronata had a lower mean value of 11.80 ± 7.19 mg/kg for trypsin inhibitor, making it an excellent addition to livestock feed. The low crude fibre and fat contents of the periwinkle samples in this study make them suitable for processing complementary foods, especially for hypertensive patients. The high percentage of CaCO3 in periwinkle shells makes them a probable source used in the production of slurry for chromatography. The findings suggest that periwinkle shells contain specific minerals that can be applied in numerous industries. Increased use of these gastropod shells will result in successful application in product creation and a sustainable bio-circular economy.

“…The increase in length after feeding might be attributed to the addition of OFSP, periwinkle, and oyster. Ivon and Eyo 12 asserted that shellfish such as periwinkle and oysters are valuable, cheap, and good sources of protein. When shellfish (protein) and millet (carbohydrate) were combined, the length of infants increased.…”

“…A survey carried out by Isingoma et al 10 showed higher percentages of stunted, underweight, and wasted children in millet-consuming communities in Uganda. Animal-source foods such as periwinkle and oyster, which are rich in protein, bioavailable minerals, and omega-3 fatty acids 11,12 , can be blended with millet-based complementary foods to improve the nutritional status of infants.…”

Background: Adequate nutrition during infancy is fundamental to ensuring children’s growth, health, and development of to their full potential. However, several national reports have indicated poor nutritional status and high prevalence of anemia among children living in low-income areas where millet-based porridge is a predominant complementary food. Aims: The study aimed to examine the effect of a millet-based fortified complementary food on the anthropometric and biochemical indices of anemic infants (6 – 24 months). Patients and Methods: One hundred and twenty children aged 6 – 24 months enrolled in this study. On six separate groups, each comprising of 20 children, they consumed Cerelac (control diet), millet / OFSP (test diet 1), millet / OFSP / carrot (test diet II), millet / OFSP/carrot / oyster (test diet III), millet / OFSP / carrot / periwinkle (test diet IV), and millet / OFSP / carrot / periwinkle / oyster (test diet V), respectively. The children were fed with 50 g/day of the diets over a period of 36 weeks during which anthropometric and biochemical assessments were performed before and after test product ingestion. Results: All children fed on the test diets had an increase in anthropometric parameters. Test diet V had the highest percent effect on biochemical and anthropometric parameters at the end of the study. The percentage effect of test diet V (109.45 %; p = 0.020) on the hemoglobin levels of the infants was significantly (p < 0.05) higher than other test diets. Conclusion: Millet-based complementary diet fortified with carrots, OFSP, periwinkle and oyster display positive effects on the nutritional status of infants. Thus, it should be considered as an appropriate alternative when planning nutrition programs to ameliorate the nutritional status of children in areas where millet-based porridge is a predominant complementary food.
