本研究研究了多家庭在公共池中饲养时，父系效应对红鳍东方鲀后代存活率的影响。4名男性和4名女性在阶乘杂交中杂交，形成16个家庭，同父异母的兄弟姐妹在一起抚养。35 d时用微卫星标记确定雄性亲缘关系。虽然母体和水箱的影响很大，但在相对存活率和标准长度（在每个水箱中标准化）中可以检测到父亲的影响，发现它们显着相关。父亲对生长速度的影响表明，在食物竞争中存在基于家庭的差异。此外，影响幼虫生长的遗传差异似乎是不同家庭之间存活率差异的部分原因。
We investigated the influence of paternal effects on progeny survival of the fugu Takifugu rubripes when multiple families were reared in communal tanks. Four males were crossed with four females in a factorial cross to give 16 families, and the half-siblings sharing the same mother were reared together. Male parentage was determined using microsatellite markers at 35 days. Although the maternal and tank effects were large, it was possible to detect paternal effects in relative survival rate and standard length (standardized in each tank), which were found to be significantly correlated. Paternal effects on growth rate suggest the existence of family-based differences in competition for food. Furthermore, genetic differences affecting larval growth appeared to be partly responsible for the disparity in survival rate observed among families.
