“…The growth and survivorship of P. acuta in the present instance are more similar to the observations made on the populations of South Africa (Brackenberry, Appleton, 1993) reared at a constant temperature of 25 ˚C. The temperature-dependent variation observed in the South African population of P. acuta is similar to those observed in the two indigenous snails Lymnaea luteola and Indoplanorbis exustus (Aziz, Raut, 1996). Under laboratory culture, the snails Lymnaea luteola(1.23 mm and 18.63 mg of shell length and body weight) and Indoplanorbis exustus (0.78 mm in shell diameter and 31.2 mg body weight) exhibited higher increment (per week) than Physa acuta (0.52 mm shell length and 2.38 mg body weight), under similar temperature conditions.…”

The life table characteristics of the invasive snail Physa acuta were assessed in the laboratory using the individuals occurring in a newly colonised area in Burdwan, West Bengal, India. Using the changes in the shell length and the body weight of the snails as surrogate, the population growth of the snails was estimated along with longevity and the fecundity schedule. The cohort of P. acuta lived for a maximum of 22 weeks with a life expectancy (ex) of 7.27 weeks and the age-specific survivorship being 0.825. Increment of the shell length of the snails complied with the von Bertalanffy growth equation, lt = 11.75(1 − exp−0.17(t−0.06)), and the observed and the expected data of the length at time t (lt) did not vary significantly (z score = 0.230; P = 0.818; n=20 pairs). Following attainment of sexual maturity between 28 and 42 days, oviposition continued till 20 weeks time, with 0.1-10 eggs laid by each individual. The eggs present per capsule remained between 01 and 11, whilst the net reproductive rate (R0), intrinsic rate of increase (rm) and the finite rate of increase (λ) were 116.07, 0.1 and 1.11, respectively. The observations are similar to those made earlier on the same species but from African and South American continents. The results of the present observation are pioneer in providing the initial studies about the life history of the invasive snail P. acuta in Indian context. Using the present information as a basis, further studies including long-term population monitoring should be initiated to understand the effects of the invasive snail P. acuta in the freshwater ecosystem of West Bengal, India.

“…Ecology of aquatic habitats is greatly influenced by temperature (Huet,1986) by controlling the ecological characteristics of organisms as well as solubility of different gases and salts in water .Temperature recorded during the study period ranging from 16.4 ºC (in Waterbody 2,December2017) to 33.4ºC (in Waterbody 1,August2017). Aziz et al (1996) reported 20ºC -35ºC is conducive for growth and multiplication of gastropods. From the above observations it can be concluded that during the study period, temperatures of the studied waterbodies were conducive for gastropod's growth and reproduction.…”

Gastropods, an important group of mollusc, inhabitants of sediment-rich bottom zone have evidentiary role in freshwater ecosystem. Their community structure has been influenced by the water and soil quality parameters. Under the scenario of intensive agricultural practice and fast urbanization waterbodies particularly the ponds of lower Damodar basin in Howrah district, West Bengal, India are badly affected by growing pollution load. In current study, three lentic waterbodies i.e Shiberjala pond, Nayachak Wetland and Dhasa Waterbody were chosen to assess the gastropod diversity. Selected physico-chemical parameters including Temperature, Dissolved Oxygen, pH, Free Carbon di oxide, Nitrate and Phosphate of all three waterbodies were determined also. Dhasa Waterbody containing 7 species, exhibited highest species richness. The density and species richness showed spatial variation among study sites. Bellamya bengalensis was the dominant species found at all study sites. Melanoides tuberculata in spite of their absence in Shiberjala pond, appeared to be the second most dominant species. Brotia sp and Bithynia sp was the least abundant species. Gastropod species richness showed significant negative correlation with DO level(r=-0.705, P<0.05).Nitrate level was significantly positively correlated(r=0.474, P<0.05) with gastropod species richness and density. Phosphate level (r=0.33) also positively correlated with gastropod richness.

“…However, it was observed that the reproduction rate of Radix acuminata in the tropics occurred optimally at a temperature range of 16–34°C [ 39 , 40 ]. Furthermore, Aziz [ 42 ] and Misra [ 41 ] found that the reproduction rate of Radix luteola (Lamarck) and Radix acuminata , respectively, was higher at lower temperature ranges of 15–20°C. In subtropical regions, 5–10°C was the minimal temperature needed for Pseudosuccinea columella and Austopeplea ( Lymnaea ) tomentosa egg development and hatching [ 66 ].…”

Background The impact of climate change has led to variations in various biological processes, leading to altered transmission dynamics of infectious diseases, including snail-borne diseases (SBDs). Fascioliasis is one of the neglected zoonotic tropical snail-borne diseases caused by the trematode of the genus Fasciola. This review focused on laboratory experimental and model studies that evaluate the potential effect of temperature change on the ecology and biology of the intermediate host snails (IHS) of Fasciola. Methods A literature search was conducted on Google Scholar, EBSCOhost, and PubMed databases using predefined medical subject heading terms, Boolean operators, and truncation symbols in combination with direct keywords: Fasciolosis AND Temperature, Lymnaea OR Austropeplea OR Radix OR Galba OR Fossaria OR Pseudosuccinea AND growth, fecundity, AND survival at the global scale. Other search terms used were (Fascioliasis AND Temperature), (Lymnaea AND Temperature), (Austropeplea AND Temperature), (Fossaria AND Temperature), (Galba AND Temperature), (Pseudosuccinea AND Temperature), and (Radix AND Temperature). Results The final synthesis included thirty-five published articles. The studies reviewed indicated that temperature rise may alter the distribution, and optimal conditions for breeding, growth, and survival of IHS, ultimately resulting in changing the transmission dynamics of fascioliasis. The literature also confirmed that the life history traits of IHS and their interaction with the liver fluke parasites are driven by temperature, and hence climate change may have profound outcomes on the population size of snails, parasite density, and disease epidemiology. Conclusion We concluded that understanding the impact of temperature on the growth, fecundity, and survival of IHS may broaden our knowledge of the possible effects of climate change and hence inform fascioliasis control programs.
