Hybrid rice varieties are planted at a lower seeding rate (33-45 kg/ha) than conventional varieties (100-120 kg/ha), making them more susceptible to tadpole shrimp damage than higher seeding rates.
These croplands include rice fields that mimic ephemeral ponds inhabited by tadpole shrimp. In 2008, <10% of the 80,000 hectares of rice production in Missouri was water seeded.
In North America, tadpole shrimp, Triops longicaudatus, are pests of water-seeded rice production in California.
