We investigated the cold hardiness of a South American freshwater apple snail, Pomacea canaliculata, which began to invade Japanese paddy fields in the early 1980s. Pomacea canaliculata exhibited apparent seasonal fluctuation in its cold hardiness. Snails collected from submerged paddy fields in summer were less tolerant to cold, and none survived exposure to 0°C for five days. With decreasing temperature, together with drainage of its habitat in autumn, P. canaliculata developed cold hardiness… 

Environmental factors affecting the increase of cold hardiness in the apple snail Pomacea canaliculata (Gastropoda: Ampullariidae)

The factors increasing cold hardiness among molluscs inhabiting different environments are compared and field-collected snails that were given sufficient food before incubation at 25°C in water showed an increase incold hardiness, but starved snails did not.

Temperature and Water Availability Affect Decrease of Cold Hardiness in the apple Snail, Pomacea canaliculata

Glycerol content reduced as cold hardiness decreased; supporting a previous hypothesis that glycerol has a major physiological role in the development ofcold hardiness in this species.

Linkage of cold hardiness with desiccation tolerance in the invasive freshwater apple snail, Pomacea canaliculata (Caenogastropoda: Ampullariidae)

Progenies of tropical snails collected from Luzon and Mindanao, the Philippines, which had never experienced cold weather revealed the same response as Japanese snails to cold stress: enhancement of cold hardiness after cold acclimation.

Cold tolerance of invasive freshwater snails, Pomacea canaliculata, P. maculata, and their hybrids helps explain their different distributions.

This study verified a role of cold tolerance in range expansion of the snails and the significance of hybridisation between the two species by comparing overwintering ability and cold tolerance among P. canaliculata, P.maculata and their hybrids.

Physiological response to low temperature in the freshwater apple snail, Pomacea canaliculata (Gastropoda: Ampullariidae)

The results indicate that indirect chilling injury is a factor in the death of P. canaliculata at low temperatures, and all of the dead, and even some of the snails still alive at 0°C, had injured mantles, indicating that the mantle may be the organ most susceptible to the effects of low temperatures.

Life cycle of the apple snail Pomacea canaliculata (Caenogastropoda: Ampullariidae) inhabiting Japanese paddy fields.

The life cycle of the apple snail Pomacea canaliculata was monitored over 2- and 1-year periods in Nara (cold district) and Kumamoto (warm district), respectively, and survivors grew rapidly with low mortality, reproduced actively in summer, and most died during the following winter.

Distribution Characteristics and Overwintering of Golden apple snails, Pomacea canaliculata (Gastropoda:Ampullariidae) at the Environment-friendly complex in Korea

BACKGROUND: Recently, the golden apple snail, Pomacea canaliculata has been used as an environmentally-friendly weed-control agent in rice farming. Although effective for this particular style of

Effects of salinity on survival, growth and reproduction of the invasive aquatic snail Pomacea canaliculata (Gastropoda: Ampullariidae)

Results show a general threshold response of P. canaliculata to salinity, which falls into “2nd degree” euryhaline limnobionts tolerating salinities of 3–8‰.

Estimating the overwintering mortality of the apple snail, Pomacea canaliculata (Lamarck) (Gastropoda: Ampullariidae) in a paddy field of Southern Japan using temperature data.

Overwintering mortality of the apple snail, Pomacea canaliculata, was investigated in a paddy field of Southern Japan for seven consecutive years and temperature data seems to be practical and effective in estimating mortality of field snails during the winter.

Environmental factors influencing overwintering success of the golden apple snail, Pomacea canaliculata (Gastropoda: Ampullariidae), in the northernmost population of Japan

To determine the location of a proper overwintering site, it is important to investigate various habitats including places where the snail density is low, and measure various environmental variables including pH, DO, and depth of water.

Predatory Potential of Freshwater Animals on an Invasive Agricultural Pest, the Apple Snail Pomacea canaliculata (Gastropoda: Ampullariidae), in Southern Japan

Predatory activities of various animals living in Japanese freshwater habitats are studied, by keeping each individual of a potential predator species with 36 snails of various sizes for three days in the aquarium, to find out why this snail maintains large populations in paddy fields but not in other freshwater habitats.

Strategies for Controlling the Apple Snail Pomacea canaliculata (Lamarck) (Gastropoda: Ampullariidae) in Japanese Direct-Sown Paddy Fields

Improving techniques for weeding and for draining fields effectively are necessary for better snail management in direct seeding in south Japan.

Decrease in density of the apple snail Pomacea canaliculata (Lamarck) (Gastropoda: Ampullariidae) in paddy fields after crop rotation with soybean, and its population growth during the crop season

C crop rotation with soybean seems to be a good economic measure to control the apple snail in direct seeding, as the snail populations increased very rapidly in both types of fields, in particular, after soybean.

The overwintering sites and cold-hardiness of Gyraulus acronicus and Valvata piscinalis were investigated in a northern Swedish river subject to wide seasonal fluctuations in water-level and ice-cover and found interspecific differences in cold- hardiness accord with the differences in overwintered habitats.

Emergence of the apple snail, Pomacea canaliculata (Gastropoda: Ampullariidae), after irrigation in a paddy

Most of the snails emerged rapidly, within five days after irrigation; this period of emergence is far shorter than past records, suggesting a higher mortality of smaller snails during the overwintering period.

Seasonal changes in the freezing tolerance of the intertidal pulmonate gastropod Melampus bidentatus say

The mean lethal temperature of Melampus bidentatus Say ranged from −5 °C in July to −13°C in December; however, there was no correlation between low water contents and an increase in freezing tolerance.
