REALIZED HERITABILITY ESTIMATES IN BOARS DIVERGENTLY SELECTED FOR TESTOSTERONE LEVELS
JOURNAL OF ANIMAL BREEDING AND GENETICS-ZEITSCHRIFT FUR TIERZUCHTUNG UND ZUCHTUNGSBIOLOGIE, 111(1), 35–42.
TL;DR:
After 10 generations, the high line was approximately three times greater than the low line for both PRE and POST levels of testosterone, and high line pigs required fewer days to reach 104 kg, had more backfat and larger testes than low line pigs.

GENETIC-VARIATION IN WEIGHT AND SURVIVAL OF BROOK TROUT (SALVELINUS-FONTINALIS)
AQUACULTURE, 38(2), 155–170.
TL;DR:
A moderate correlation between egg weight and 243 day survival, and a low, but positive correlation betweenegg weight and 223 day weight suggests that selecting heavier eggs would improve both weight and survival, suggest that selection for increased 243 day weight would indirectly select against survival.
