Channeled and island apple snails are opportunistic feeders that consume a variety of aquatic vegetation, fruits and vegetables, algae, remains of decaying organisms and other snail eggs. Because of damage to crops, the channeled apple snailis listed as one of the worlds worst invaders.Species Facts: The Channeled Apple Snail has a voracious appetite for water plants including lotus, water chestnut, taro, and rice. This snail poses a serious threat to many wetlands around the world by the potential destruction of native aquatic vegetation that causes serious habitat modification, as well as c ompetition with native fauna, channeled apple snail eggs

These egg masses are laid on solid surfaces up to about 20 inches above the water surface. An average channeledapplesnail clutch contains 200 to 600 eggs, with each egg measuring 0. 9 to 1. 4 mm in diameter. An average islandapplesnail clutch usually contains more than 500 eggs, slightly smaller than those of its sister species.

these large snails or eggs may be transported on aquatic vegetation. RISKSIMPACTS: Like all invasive species, the channeled apple snail has the potential to compete with native species for limited resources. Channeled apple snails feed on all types of aquatic plants; large consumption of plants could alter the natural balance of a water system. However, it is the channeled applesnail, Pomacea canaliculata (Lamarck, 1828), that causes concern to farmers. The channeled applesnail has caused significant damage to rice and taro crops in the Pacific islands and in southeastern Asia. Fortunately, this species has not been documented from Florida.channeled apple snail eggs channeled apple snail Pomacea canaliculata Lamarck, 1819. Overview. Origin Females lay clusters of bright pink eggs above the water line. They are attached to solid surfaces such as rocks, piers, emergent vegetation or trash. Within 715 days the eggs usually hatch. Each mass of eggs can contain from 200 up to 1000 eggs.

View all resources for Channeled Apple Snail channeled apple snail eggs If you find these channeled apple snails andor their eggs, or want more information, please contact Johnny Richardson, Water Quality Scientist, Leon County Public Works, at or call (850). The eggs are enclosed in a calcium carbonate shell, which may or may not be used as a source of calcium for the developing embryo. Their bright pink colour serves as a warning to predators and the eggs as a result have very few predators (see also Dreon et al. , 2010). These bright pink eggs are often the first visible signs of an infestation. Within 715 days the eggs usually hatch. Each mass of eggs can contain from 200 up to 1000 eggs. Females can live up to 4 years and lay eggs every few weeks. Sexual maturity is reached when the snail reaches a certain size. A snail living under ideal conditions may reach sexual maturity much sooner than one living under poor conditions Pomacea canaliculata, commonly known as the golden apple snail or the channeled apple snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails.
