| 内容記述 | The biological mimimum sizes and growth rates of six species of barnacles have been determined by examination of speciments taken from rafts or intertidal piles and measuring the rostro-carinal diameter of animals growing on glass panels suspended from a raft. The size and age at first maturity were determined as follows; B. improvisus 4.5mm basal diameter (17 days), B. albicostatus 5.2mm (17days), B. reticulatus 7.5mm (?), B. amphitrite 7.3mm (22days), B. eburneus 12.0mm (50days) and B. kondakovi 10.0mm (?). From comparison of these results with other barnacles, it follows that all of the barnacles studied here show early age and smaller size at first maturity. Initial growth in rostro-carinal direction is slow until 6 days or so after settlement,barnacles reaching apporoximately 1 mm in basal diameter. From 6 to 18 days the rate of growth of any species accelerates and barnacles become 3.5 to 5.0mm large at the end of this period. Subsequent declines of the growth rate is expected to be due to the sexal maturity. Until 10 days after metamorphosis barnacles tend to expand the basal margin rather than the opercular portion. |
