The discarded shells were all over the place, as the . Therefore, a laboratory study was conducted to determine the feeding preference and growth pattern of P. canaliculata and P. maculata for rice and L. flava based on choice and no-choice experiments. Aquatic habitats have been highly modified by human actions that reduce their native diversity and create conditions suitable for tolerant alien species. Geological Survey Wetland and Aquatic Research Center, 700 Cajundome Boulevard, Lafayette, Louisiana 70506 USA This is an insane speed at which these snails can move. They are brown in color and have a . The presence of an exotic snail, Pomacea maculata, inhibits growth of juvenile Florida apple snails, Pomacea paludosa. To control crop damage, farmers stopped flooding their rice fields in winter, an agri-environmental scheme (AES) applied for more than 20 years in some European and American regions to favor flora and fauna . The markets never developed; the snails escaped or were released, and P. canaliculata became a serious pest of rice throughout many countries of south-east Asia. In Hawaii, Pomacea canaliculata have rapidly spread to non-agricultural habitats (Lach and Cowie 1999 ).
