本文研究了光周期和温度调控对三种不同生长周期的尖吻天牛生殖周期的影响。实验中的“高级组”通过调节光温循环来模拟一年中的两个生殖季节。受高级条件影响的刺参每年有两个生殖周期，以正常速度生长，几乎没有额外的死亡率。许多刺鱼科学家的研究将受益于更快的世代时间，我们的方法可能会缩短为遗传、行为和形态工作生产鱼类所需的时间。
The effects of photoperiod and temperature manipulation on reproductive cycles in threespine sticklebackGasterosteus aculeatuswere examined. The experimental “advanced group” conditions were adjusted to simulate two reproductive seasons within a calendar year by adjusting light and temperature cycles.G. aculeatussubject to advanced conditions had two reproductive cycles per year, grew at normal rates and suffered little additional mortality. The research of many stickleback scientists would benefit from faster generation times and our methods could potentially shorten the time required to produce fish for genetic, behavioural and morphological work.
