  1. Standard errors are given in brackets. When adjusting SW and EN for a constant FW, their genetic correlations with FW dropped to respectively −0.26 (±0.14) and − 0.17 (±0.16), while the phenotypic correlations were close to zero with respective estimates of − 0.05 (±0.04) and 0.06 (±0.04)
  2. SD Spawning date; FW Female body weight; SW Spawn weight; EN Egg number; EW average egg weight; ED Average egg diameter
