Species such as the golden apple snail are putting the agricultural sector in the Ebro river basin in quite a predicament. [24] Because submerging developing eggs below the water reduces hatching success, manipulating the water level in agricultural fields and dammed reservoirs may provide a tool for controlling invasive populations. During the dry season when these snails are concealed under dried mud, collectors use a spade to scrape the mud in order to find them. The critical time to manage golden apple snails is during land preparation and crop establishment or planting; specifically, first 10 days after transplanting (DAT), and during the first 21 days after direct wet-seeding. However, it is important to take extra care and cook the snails thoroughly, as they are known carriers of the rat lungworm. Apple snails can live together with most fish without problem, but snail eating fish species should be avoided (obvious). The island applesnail, Pomacea insularum, appears nearly identical. It has brought about economic losses to aquatic crops in the Philippines that are estimated to be up to USD 1200 million per annum without taking into account the non-crop damage to human health and natural ecosystems. To best control the snail, communities should work together to reduce snail numbers in their area. A species of aquatic snail that encompasses the mystery snail, the Golden Inca snail, and many others, the apple snail is an easy addition to any tank.

South American in origin, this species is considered to be in the top 100 of the "World's Worst Invasive Alien Species". Despite its prevalence, it isn’t an endemic species. The duration of the reproductive period of P. canaliculata decreases with latitude, to a minimum of six months in the southern limit of its natural distribution. Using a field survey dataset for the invasive golden apple snail P. canaliculata in China, we examined the ASR, quantified its variation across multiple spatial and temporal scales, and analyzed the potential associations between ASR and abiotic/biotic factors. [11], In temperate climates, the egg-laying period of this species extends from early spring to early fall. Two species, Pomacea canaliculata and Pomacea maculata, commonly known as Golden Apple Snails, are highly invasive and cause damage to rice crops. See more videos on the IRRI RKB YouTube Channel.

Small and stout, it has a black head and a reddish-brown body, and prefers open fields and grassy areas. Transplanted rice is less vulnerable than direct seeded rice. If used, molluscicides should only be used immediately after transplanting or during the seedling establishment phase in direct seeded rice; and only for rice younger than 30 days old. Raise seedlings in low density nursery beds, i.e., less than 100 g seeds per m2 and delay transplanting (e.g., transplant 25−30 day-old seedlings).
