Family–tank interactions on early growth performance of yellow perch reared in single-family tanks versus mixed-family tanks as inferred using microsatellite pedigrees

摘要: From 17 families, 400 fingerlings were evenly stocked into four replicates of each five groups: single family from an Ohio strain, a North Carolina three families the cross strains, 12 strains and combination all families. After rearing for 27 weeks, progeny could be confidently assigned to their origin at rate 97.9%. The cross-bred multi-families (12-family 3-family groups) different gained significantly more weight than both single-family groups in separate tanks throughout most experiment (P 0.05). Both grew faster all-family communal by end (P<0.05). In addition, no correlation was detected between mean obtained multi-family tanks. These results indicated that there strong effects genotype environment interactions on early growth performance yellow perch.
