The survival and growth of P. monodon from six breeding families were evaluated in this study. The morphometric traits, including the carapace length, carapace width, body length, telson length and body weight were measured throughout 108-days growth experiment. Ratios of the telson length and carapace width to body length, the length-weight relationship (LWR), condition factor (K), weight gained rate (WGR), specific weight rate (SWR), and survival of P. monodon were calculated. The testing traits were varied in selected breeding family. Length-weight relationships of family1 can be expressed as W = 0.0126BL^3.064 (R² = 0.9473) which had the biggest slope value (b). The equation W = 0.0563BL^2.417 (R² = 0.8318) belong to family2, while the slope value less than 3 indicates that the animal becomes slender as it increases in length. The order of the survival rate was family4 > family1 > family2 > family3 > family6 > family5.The order of the specific weight rate and weight gain rate was family6 > family4 > family2 > family5 > family3 > family1. In comparison of the condition factor between different families, the highest condition factor (1.57) was observed in the family5, and the lowest condition factor (1.40) was the family6. According to above indexes, rearing performance of family4 was the best in the tested breeding families in this study.
