| Research Abstract |
The present study developed the seed production technology and examined the genetic population structure for supportive breeding of the coconut crab Birgus latro. We revealed the optimal rearing condition of zoeae and megalopae such as water temperature, light intensity, photoperiod, humidity, and shell and shelter availability for mass seed production. The sequence analysis based on mtDNA COI region showed small genetic differentiations among crab samples collected from the North Pacific Islands.
