説明

<p>We studied the life history of Neocaridina davidi (Bouvier, 1904), native to mainland China and Korea, invading the Tomoe River, in the Boso Peninsula of eastern Japan. Sampling was carried out monthly from November 2012 to October 2013. Recruitment occurred from July to September, and the spawning season was from April to September. Large males with a carapace length more than 6.0 mm were rarely collected or absent from July to August, and, similarly, large females with a carapace length more than 7.0 mm were rarely collected or absent from September to October. Evidence from the current study suggests life span for this species is approximately 10–15 months. The life history of N. davidi is very similar to that of a congeneric species, N. denticulata, reported in previous studies.</p>
