本文对布尔氏朴丽鱼（Haplochromis burtoni）发育速率的社会调节进行了实验研究。在三种不同的社会条件下抚养后代：完全隔离，与兄弟姐妹没有视觉，物理或化学接触;物理隔离，与兄弟姐妹没有物理或化学接触;和社会群体。观察了2 ~ 14周龄鱼的行为和颜色模式的发育。每隔4周处死雄性动物，以测量生长和成熟状态。结果表明，社会环境影响儿童的发育速度。没有领土的雄性（在群体中长大）比其他条件下的雄性生长和成熟得更慢。这些男性没有阻止成熟，但成熟的速度和表型表达受到抑制。
Social regulation of developmental rate of the African cichlid fish, Haplochromis bur-toni, was studied experimentally. Broods were raised under three different social conditions: total isolation, with no visual, physical or chemical contact with siblings; physical isolation, with no physical or chemical contact with siblings; and in social groups. Development of behavior and color patterns were observed in fish from 2 to 14 weeks of age. Males were sacrificed at 4-week intervals to measure growth and maturation state. Results showed that developmental rate is influenced by the social environment. Males with no territories (raised in groups) grew and matured more slowly than those in all other conditions. These males were not prevented from maturing but both the rate and phenotypic expression of maturation were inhibited.
