“…Nonetheless, further investigations are required to unveil the related mechanisms governing this phenomenon. When exposed to the stress of shell damage, P. canaliculata likely undergoes a series of physiological and biochemical responses, including the activation of specific biochemical pathways to cope with external pressures 50 – 52 . These responses can lead to alterations in body fluid composition, subsequently affecting egg development and size.…”

Pomacea canaliculata was by far one of the most harmful invasive organisms in the world, causing serious harm to aquatic crops and ecosystem. Calcium carbonate is a common component of aquatic environment, which is important for the growth of Pomacea canaliculata. Therefore, the objective of this study was to investigate the response characteristics of P. canaliculata suffered shell breakage to the addition of calcium carbonate in water environment. In this experiment, we explored the effects of calcium carbonate addition on the P. canaliculata shell repair rate, food intake, egg production, shell strength, and calcium content through breaking the snails shell and the addition of calcium carbonate treatment. The results showed that snail broken-shell repaired mostly within 21 days. The snails experienced a significant increase in shell repair rates during earlier days of the treatment, especially for female snails. Food intake of snails exhibited different patterns when their shells were broken and calcium carbonate was added. Shell breakage treatment combined with calcium carbonate addition significantly increased the diameter of snail eggs compared with the control and the calcium carbonate addition treatment without shell-broken snail group. There was no significant difference in shell strength or calcium content of male snails between the treatments. The study suggests that P. canaliculata exhibits a sex-dependent response pattern when subjected to shell damage and calcium carbonate addition. The findings can provide some references to better understand the invasion mechanism and survival strategy of the P. canaliculata.

“…The invader Pomacea canaliculata exhibits remarkable adaptability to variations in temperature, drought, and water pollution, enabling them to establish populations promptly in both natural and man-made aquatic environments [11][12][13][14][15]. Their ability to survive and reproduce in salt-affected environments is noteworthy, with studies revealing their capacity to endure stressors of 8 practical salinity units (PSU) for 25-31 days [16]. Furthermore, their eggs can survive and develop through recurring saltwater tides [17].…”

Recent studies have indicated that the invasive apple snail (Pomacea canaliculata) exhibits tolerance to the salinity levels present in coastal agricultural soils, suggesting that apple snails could potentially invade salt-affected coastal agricultural areas. However, the effects of the alien snail Pomacea canaliculata invasion on coastal saline soils, such as in terms of soil properties, microbial diversity, and abundance, remain poorly understood. To fill this gap, we conducted experiments involving three salinity levels (0, 2‰, and 5‰, w/w), coupled with varying snail densities (0, 5, and 10 snails per box), applied to agricultural soil. We analyzed soil chemical properties, enzyme activities, and bacterial communities. The findings revealed that heightened soil salinity increased soil electrical conductivity (EC) (exceeding 1312.67 μS cm−1). Under saline conditions, snail treatments significantly increased the soil organic matter (SOM) content from 15.82 mg kg−1 to 18.69 mg kg−1, and concurrently diminished the dissolved organic carbon (DOC) from 47.45 mg kg−1 to 34.60 mg kg−1. Both snail and salinity treatments resulted in ammonia nitrogen (NH4+-N) accumulation, while nitrate nitrogen (NO3−-N) concentrations remained low in salt-affected soils. A notable positive correlation existed between the EC and the activities of hydroxylamine reductase (HR) and peroxidase (POD), where HR exhibited a positive correlation with NH4+-N, and POD displayed a negative correlation with NO3−-N. Salinity substantially decreased the diversity and altered the composition of soil bacterial community, with the phyla Bacteroidota, Proteobacteria, and Firmicutes adapting to salt-affected soil environment and proliferating. Structural equation modeling (SEM) analysis indicated that snails exerted a direct influence on soil-available nitrogen (including NO3−-N and NH4+-N), while salinity impacted available nitrogen by modulating soil enzyme activities and bacterial communities. Our findings provide insights into how soil responds to the concurrent impacts of snail invasion and soil salinization, establishing some references for future research.

“…The species in the genus Pomacea spp., specially P. canaliculata and P. maculata , also known as Golden apple snails, are among the world's most critical invasive species, which had been introduced to Taiwan during the 1980's for dietary protein supplementation and commercial utilization (Cheng and Kao, 2006;Hayes et al, 2008). The rapid proliferation due to high reproduction rate, fast growth, and stress tolerance created a widespread sympatric distribution of two cryptic species of Pomacea in Taiwan:Pomacea canaliculata (Lamarck 1819) and P. maculata(Perry, 1810) (Banerjee et al, 2022;Hayes et al, 2008;Qin et al, 2022). These snails cause destruction to local agriculture as well as to the native ecological balance, besides acting as intermediate host to the dangerous parasite: Angiostrongylus cantonensis .…”

Angiostrongylus cantonensis(Rat Lungworm) is a major pathogen of Eosinophilic Meningitis in humans worldwide. Angiostrongylus cantonensis generally completes its life-cycle in two hosts: the rats as definitive and the gastropods as intermediate hosts. Among the wide range of intermediate hosts is the critically invasive Pomacea canaliculata (Golden apple snails), which have caused numerous outbreaks of neuroangiostrongyliasis worldwide, especially China and Taiwan. While there have been numerous surveys on the prevalence of Angiostrongylus cantonensis larvae in P. canaliculata in China, there are an inadequate number
