  1. Heritability estimates are in bold on the diagonal, genetic correlations are in the upper triangle, phenotypic correlations are in the lower triangle for standardised time to loss of equilibrium in the acute hyperthermia challenge (TLE); BW1 body weight of batch 1, BW2 body weight of batch 2, FL fork length, Fat% fillet fat percentage, HGC% headed gutted carcass yield. All values are given ± standard error. NA not applicable as traits were measured on different individuals
