ResumenThe aim of this study was to estimate genetic parameters for spawning traits and growth traits in a breeding line of Pacific white shrimp, Penaeus (Litopenaeus) vannamei, selected for growth and survival. Traits studied were number of eggs (NE) and number of nauplii (NN) and female body weight at insemination (FWI) and body weight at 130days of age (BW130). Genetic parameters were estimated using a multivariate animal model. Heritability for NE and NN were estimated as 0.13 +/- 0.04 and 0.03 +/- 0.04 respectively. The contribution to NN total variation due to factors associated with male' effect was estimated as 0.47 +/- 0.07. In the cases of FWI and BW130, heritability was estimated as 0.44 +/- 0.08 and 0.19 +/- 0.03 respectively. Genetic correlation between FWI and NE was estimated as 0.49 +/- 0.15, between FWI and NN as 0.54 +/- 0.39 and between NE and NN as 0.27 +/- 0.41, whereas the genetic correlations of FWI, NE and NN with BW130 were 0.30 +/- 0.13, -0.21 +/- 0.19 and -0.25 +/- 0.38 respectively. Although it is important to perform more studies on this issue, our results found no evidence of a genetic antagonistic effect between female reproductive traits and body weight at harvesting (130days of age) in P. vannamei.es_ES
