| Outline of Final Research Achievements |
Successful hatching rate decreased at high temperature conditions in a certain atyid shrimp species. Interspecific variations were found in appropriate foods, salinity and temperature conditions for larval survival and development in atyid shrimps. Some species adapted to low temperature and phytoplankton-rich conditions occurring in inner bays, whereas other species adapted to high temperature and salinity conditions occurring in summer open seas. Larval environmental adaptations may affect the larval dispersal ability in the sea; thus, increasing seawater temperature depending on the global warming may affect the larval dispersal range of atyid shrimps in the sea, resulting in increasing the extension risk of the populations.
