坦干尼坎双亲本丽鱼Perissodus microlepis的种内杂交被归因于“放养”，这种行为是父母将部分或全部自由游动的幼鱼放入口中，并将其置于其他看守父母的照顾下。我们在自然条件下进行了观察，以了解外包发生的频率以及哪种性别是主要表演者。在大多数繁殖地，幼崽在达到独立的规模之前就完全消失了。在许多这样的地方，雄性的外出务农及其前兆行为先于它们的后代消失。女性从未进行过外包。我们提出雄性寄主是一种替代遗弃幼崽的策略，以逃避父亲的角色。
SynopsisIntraspecific brood-mixing of a Tanganyikan biparental cichlid fish Perissodus microlepis has been attributed to farming-out, a behaviour in which a parent transport some or all of their free-swimming young in the mouth and put them under the care of other guarding parents. We conducted observations under natural conditions to understand how often farming-out occurs and which sex is the primary performer. At most brooding sites, young in a school entirely disappeared before attaining to the size of independence. At many of these sites, farming-out and its precursory behaviours by males preceded disappearance of their young. Females never performed farming-out. We proposed that farming-out by males is an alternative tactics to brood desertion to evade paternal roles for remating.
