Groups of eight full‐sibling wild sea trout Salmo trutta L. families, communally reared, exhibited highly significant differences in family representation in the largest 25 percentile within each tank at the end of the observation period (referred to as family performance). Despite these large differences in family performance within tanks, there were no significant differences in performances of families relative to each other between high and low feeding levels. These results are discussed in the context of domestication selection.
