“…To manage the P. canaliculata populations in paddies, we should determine their population dynamics, particularly the densitydependent processes. The snails damage only young rice plants, and the damage depends on the shell size and density of snails Yano and Nakatani 1989;Litsinger and Estano 1993). A possible strategy for snail management is to attempt to control those snails large enough to inflict damage on rice plants or to prevent the snails from damaging rice plants by some method during the vulnerable growth stage of rice.…”

“…By 1996 in Japan, the snails had spread to more than 50 000 ha of paddy fields in 28 prefectures (Wada 1997). In Asian countries in which the direct-seeding rice farming system has recently been propagated, P. canaliculata has developed into one of the most serious rice pests because the snail prefers young seedlings of rice plants (Litsinger and Estano 1993;Halwart 1994;Wada 1997).…”

Density‐dependent growth and reproduction of the apple snail, Pomacea canaliculata: a density manipulation experiment in a paddy field

To examine density dependence in the survival, growth, and reproduction of Pomacea canaliculata, we conducted an experiment in which snail densities were manipulated in a paddy field. We released paint-marked snails of 15-20 mm shell height into 12 enclosures (pens) of 16 m 2 at one of five densities -8, 16, 32, 64, or 128 snails per pen. The survival rate of released snails was 95% and was independent of snail density. The snail density had a significant effect on the growth and egg production of individual snails. This density dependence may have been caused by reduced food availability. The females at high density deposited fewer and smaller egg masses than those at low density, and consequently produced fewer eggs. The females at densities 8 and 16 deposited more than 3000 eggs per female, while the females at density 128 oviposited only 414 eggs. The total egg production per pen was, however, higher at higher snail density. The survival rates of juvenile snails were 21%-37% and were independent of adult density. The juvenile density was positively correlated with the total egg production per pen and hence was higher at higher adult density. However, the density of juveniles larger than 5 mm in shell height, i.e., juveniles that can survive an overwintering period, was not significantly different among density treatments. These results suggest that snail density after the overwintering period is independent of the density in the previous year. Thus, density dependence in growth and reproduction might regulate the population of P. canaliculata in paddies.

“…The apple snail Pomacea canaliculata (often referred to as the golden apple snail in Southeast Asia) was introduced to Japan and many other countries in Southeast Asia in the early 1980s 4,5,10,14 . This fresh water snail from South America was initially introduced to Asia as a source of human food.…”

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

The apple snail Pomacea canaliculata becomes a much more serious pest in direct-sown rice fields than in transplanted fields. In south Japan, it represents an important constraint on the implementation of direct seeding. Described here are possible measures to control the snails and suggestions for its management in Japanese direct-sown rice fields. Crop rotation with upland crops is a practical way with the lowest extra cost. The apple snails were often not eradicated by growing an upland crop in the previous summer. However, snail densities always decreased below the control threshold in directsown fields (0.5 snails/m 2 ). Longer drainage period after sowing greatly reduced snail damage. Thus, draining fields for 10 to 20 days after sowing is a basic practice to control snails in direct seeding. Tillage and puddling have a function to crush snails and, thus, reduce snail densities. "Intensive tillage", in which a field with compacted hard soil is tilled shallow with faster cultivator rotation, achieved higher snail mortality. It is recommended to lower the risk of snail damage after unexpected heavy rain. An application of bait type metaldehyde showed enough control effects to avoid rice damage by snails even in heavy rain conditions. The stable effects seemed to be due to the active ingredient in the bait type which is dissolved slowly. Improving techniques for weeding and for draining fields effectively are necessary for better snail management in direct seeding.

“…It was introduced from Argentina to Taiwan in the 1980s for commercial production (Mochida 1991) and was distributed widely in Asia as a dietary protein supplement and income earner for the rural poor (Matienzo 1984;Anderson 1993). Unfortunately the introduction of P. canaliculata was done in haste without prior studies on its ecological impact or market information (Acosta and Pullin 1989).…”

“…Pesticides were selected rather arbitrarily, applied inappropriately (causing environmental pollution) and were a hazard to public health with farmers suffering a range of health problems (Anderson 1993). Several control techniques have been developed, including biological (Halwart 1994b;Teo 2001), cultural (Teo 2003) and chemical (Litsinger and Estano 1993;Palis et al 1994) controls. Information on the biology and ecology of the snail are also becoming available, most recently in a review by Cowie (2002).…”

This study investigated the ecology and biology of the golden apple snail in rice fields. Egg masses were produced at inconsistent intervals with the number of eggs per cluster ranging from 92 to 592 (mean 272). Regardless of clutch size, hatching success ranged from 87 to 100% (mean 95.8%). In the field, mating took place 82 days after hatching. Mean shell length at this age was 38.2 mm with females bigger than males in general. The male to female ratio was ~1: 5. Peat soils reduced egg mass production significantly and egg masses submerged in water for more than 1 week reduced hatching success significantly.
