摘要

Abstract

Although amphioxus is widespread in temperate and tropical seas

its population is diminishing because of environmental pollution. To keep the population of this evolutionarily important animal from diminishing

study on its reproduction and development is necessary. The main findings in this study on the spawning and fecundity of the amphioxus reared in laboratory and its larval development are as follows. 1. Water temperature markedly affected the spawning. It spawned only when water temperature reached 21°C. 2. Spawning of the amphioxus in laboratory was markedly extended. Initially

the amphioxus spawned at about 7:00 PM

but spawning time was postponed as spawning days went on. 3. The number of eggs produced by a female ranged from 1400 to 12800

average of 5800. This also represents the fecundity of the amphioxus because it shedded all eggs within the ovary at a time. 4. During the first few months of life of the amphioxus

its growth rate changed seasonally. The growth rate in summer and fall was greater than that in winter. 5. The pelagic larva became a benthic adult after 50 days. 6. The amphioxus reared in laboratory from fertilized eggs could produce fertile eggs and sperms. These findings can be a foundation for measures to address the problem of diminishing amphioxus population.
