海水鱼类的幼体死亡率与个体生活史特征(如大小和生长)密切相关，但影响这些特征变异的过程却鲜为人知。我们探讨了母本和父本影响以及水温对热带小丑鱼Amphipron Blackopus(Pomacentridae)幼体生长和性能特征的相对重要性。幼虫由不完全的4雄4雌双列杂交在2种温度(25℃和28℃)下饲养。父子关系与母体和受影响的性状在孵化前和孵化后立即交互作用。幼虫变态时的大小主要受母本和父本的影响，而不受饲养温度的影响。父子关系解释了变态生长率差异的52%，而父子关系、母体和温度的组合解释了30%。这种强烈的父性影响可能是由于雄性在巢中扮演着广泛的角色，加上该物种相对较长的胚胎持续时间。水箱内幼虫生长率和死亡率之间的负相关关系强调了这些亲本效应对幼虫存活的重要性，也为“越大越好”的假设提供了支持。
Larval mortality in marine fishes is strongly linked to individual life history traits such as size and growth, but the processes that influence variability in these traits are poorly understood. We explore the relative importance of maternal and paternal influences and water temperature on the larval growth and performance characteristics of the tropical clownfish Amphiprion melanopus (Pomacentridae). Larvae were reared from an incomplete 4 male × 4 female diallel breeding cross at 2 temperatures (25 and 28°C). Paternity interacted with maternity and affected traits immediately prior to and after hatching. Size of larvae at metamorphosis was primarily affected by maternal and paternal influences, but not by rearing temperature. Paternity explained 52% of the variance in growth rates to metamorphosis, while the combination of paternity, maternity and temperature explained 30%. This strong paternal influence may be due to the extensive role males play in nest-tending coupled with the relatively long embryonic duration of the species. A negative relationship between larval growth rate and mortality within a tank emphasised the importance of these parental effects to larval survival and also provides support for the ‘bigger is better’ hypothesis.
