“…Los resultados del modelo de SC fueron consistentes con estimaciones, usando modelos univariados, considerando una distribución binomial (resultados no mostrados). Las heredabilidades para SC en SMB-ausencia fueron 0.01 ± 0.03 en CRE y 0.06 ± 0.04 en RES concordantes con otros estimadores para supervivencia general (Campos-Montes et al, 2013;Zhang et al, 2017;Ren et al, 2020), pero menores a los presentados por Lu et al (2017), Luan et al (2020, y Tan et al (2017), donde no se incluyó el efecto de ambiente común de familia, lo cual podría haber generado una sobrestimación de los parámetros genéticos. Las heredabilidades en CRE fueron esencialmente cero en ambos ambientes, 0.01 ± 0.02 en SMB-presencia y 0.02 ± 0.03 en SMB-ausencia, lo cual, representa mínimas posibilidades de avance genético por selección para esta característica en ambos escenarios, lo cual es consistente con otros autores (Gitterle et al, 2005a;Campos-Montes et al, 2013;Li et al, 2015;Lu et al, 2017).…”

“…La h 2 para SC en SMBpresencia fue superior la estimada por Caballero-Zamora et al (2015) 0.06 y a la reportada por Gitterle et al (2005b), que calculó valores entre 0.03 a 0.07. La h 2 para SMB-ausencia fue concordante con otros estimadores para supervivencia general en la misma especie (Campos-Montes et al, 2013;Zhang et al, 2017;Ren et al, 2020). Las heredabilidades de SC para ambos ambientes fueron consistentes en ambas líneas (cuadro 3), sugiriendo que no existe una compresión de la varianza aditiva, en las líneas, asociada al ambiente (Sae-Lim et al, 2016).…”

Este estudio tuvo como objetivo estimar la interacción genotipo por ambiente para peso corporal (PC) y supervivencia a cosecha (SC), en presencia y ausencia de Síndrome de Mancha Blanca (SMB) en dos líneas genéticas de Penaeus vannamei (Crecimiento -CRE-y resistencia a SMB -RES-). La heredabilidad para PC en la línea CRE fue 0.05 ± 0.16 en presencia de SMB y 0.35 ± 0.15 en ausencia, mientras que para la línea RES fueron 0.26 ± 0.07 y 0.49 ± 0.08 en presencia y ausencia de SMB, respectivamente. Las correlaciones genéticas para PC entre ambientes fueron -0.17 ± 0.60 para CRE y 0.89 ± 0.09 para RES. La heredabilidad para SC en CRE fue 0.01 en ambos ambientes y la correlación genética no fue estimable, mientras que, para RES, las heredabilidades fueron 0.06 ± 0.04 y 0.11 ± 0.06 en ausencia de y presencia de SMB, respectivamente, adicionalmente, la correlación genética no fue significativa. Aunque el modelo lineal sugiere una interacción genotipo por ambiente, los estimados proponen independencia de la misma característica entre ambientes y, las correlaciones entre características para la línea de resistencia proponen seleccionar de manera independiente las características cuando SMB esté presente.

“…Shrimp nauplii used in our study came from a single mass spawning on a single night in a commercial hatchery owned by the Beijing Shuishiji Biotech Ltd. at Wanning, Hainan Province, China. Genetic background of broodstock had been described in previous study (Ren S. J. et al, 2020). Larval culture and the nursery phase occurred from 1st July to 20th July, 2017.…”

“…Shrimp were stocked into RT using the same standard procedure used in the family growth parameter study as described in Ren S. J. et al (2020). RT tanks were circular polypropylene fiber tanks (3.5 m diameter, 0.9 m depth), with the water column depth maintained at 0.5 m. A biological recirculating culture system was used to maintain water quality at an exchange rate of 600 to 800% per day.…”

Ren et al. Reproductive Performance of L. vannamei female reproductive performance for multiple spawning individuals compared with first or second spawning order events for all reproductive parameters evaluated (P > 0.05). The data generated here will be used to optimize a genetic breeding strategy for our broodstock line and to develop a seed distribution strategy for the local production sector in China.

This study aimed to estimate the additive and dominance genetic variance in growth and multiple stress‐tolerance traits in 7 week and 15 week Litopenaeus vannamei shrimp. Four different animal models were studied by including all or different subsets of the following effects: additive genetic effects (A), additive genetic and common environmental effects (A+C), additive genetic and dominance effects (A+D), and additive, common environmental, and dominance effects (A+D+C). Variance components were estimated using the Average Information Restricted Maximum Likelihood (AIREML) method. In general, estimates of additive genetic variance were inflated under the simple model (A) and decreased remarkably under the more complex models (A+C, A+D, and A+D+C). The genetic parameters of two‐stage (7 week and 15 week shrimp) growth and multiple stress‐tolerance traits were more suitable for estimation using the A+C model. The additive effects (0.311~0.754) of seven traits in 7 week shrimp were greater than the dominance effects (4.950× 10‐7~0.201), whereas the additive effects of the same seven traits in adult shrimp ranged from 7.712×10‐8 to 0.468 and the dominance effects ranged from 0.074 to 0.577. Except for survival time, carapace length, and carapace width, the additive effects of the other traits were smaller than the corresponding dominance effects. Thus, better genetic improvement of 7 week and 15 week shrimp growth and multiple‐stress tolerance can be obtained with selective breeding than with cross‐breeding, and better genetic improvement of 7 week shrimp growth traits can be obtained with cross‐breeding than with selective breeding. Our study further enriches the database for enhancing growth and stress resistance in L. vannamei and provides reference information for growth improvement and multiple stress‐resistance breeding.
