The experiment was conducted using selective pop- lt br gt ulation of generation 4 with 97 families tested in 3 environments. lt br gt Growth body weight and survival rate at harvest weight were lt br gt Keywords recorded and evaluated. There was no genotype by environment lt br gt interaction for both traits with high genetic correlations of the lt br gt same traits tested between ponds in the Central and in the South lt br gt Black tiger shrimp lt br gt of Vietnam of 0.80 and 0.83 respectively. There was also no lt br gt Genotype by environment interaction genotype by environment interaction for growth rate between lt br gt Growth ponds in the South of Vietnam and bio-security indoor tank lt br gt Survival rate with high genetic correlation of 0.91. These results indicated lt br gt that the number of testing environments would be reduced to lt br gt .
