摘要：坦噶尼喀湖的食草性慈鲷Tropheus duboisi的饲养领土，对同一个人，但不是异性的防御。雄性的活动范围是雌性的3倍大，每一个都与2-5个雌性的活动范围重叠。在雄鱼的领地产卵后，每只雌鱼在自己的领地内积极觅食，同时在口腔中孵化幼鱼。在6个月的观察期内，雄性和雌性都很少转移它们的领地。这种鱼的社会组织进行了比较，一个同源，Tropheus moorii。
Abstract– The herbivorous cichlid fish Tropheus duboisi in Lake Tanganyika held feeding territories that were defended against individuals of the same but not the opposite sex. The male home ranges were 3 times as large as female home ranges, each overlapping with the ranges of 2–5 females. After spawning in the male's territory, each female foraged actively within her own territory while brooding the young in the buccal cavity. Both males and females rarely shifted their territories during the 6-month observation period. The social organization of this fish was compared with that of a congener, Tropheus moorii.
