| 内容記述 | We investigated the population structure and growth of the amphioxus Branchiostoma belcheri for four years in the southern Ariake Sea, Japan. We counted 62-66 myotomes and 251-310 dorsal fin-ray chambers, and these results support that this species is an intermediate form of B. belcheri and its subspecies B. belcheri tsingtauense. The ratio of females to males was 1:1.12. Males were more numerous than females among small individuals (<40mm body length), but we found no significant differences among large animals (≥50mm body length). Spawning occurred from mid June to early July. Groups of newly settled young appeared from January to June of their second year. We observed a large fluctuation between years in the numbers of newly settled young. The estimated size of one-year-old individuals was 19.4mm in body length; within the next 12 months, they reached 32.1mm. Three- and four-year-old individuals measured 38.6mm and 45.8mm, respectively. Few grew beyond 60mm; the largest specimen collected was a 64mm male. | |||||
