Alfaro-Montoya, Jorge Decapoda Penaeidae Litopenaeus vannamei commercial culture shrimp Decapoda Penaeidae Litopenaeus vannamei cultivo comercial camarones Decapoda Penaeidae Litopenaeus vannamei cultivo comercial camarões Compensatory growth and production of Litopenaeus vannamei in commercial cultures in farms in the Gulf of Nicoya, Costa Rica, during 2014 were evaluated in this study. Growth and production were compared between three culture systems starting from an initial maternity (MA) phase with high stocking density (85/m2) of post larvae: a) maternity-development (MA-DE) with a medium stocking density (23.3/m2) and an initial weight of 1.4 g, b) maternity-development-grow-out (MA-DE-G) with a low density (8.6/m2) and an initial weight of 6.0 g and c) maternity-grow-out (MA-G) (9.4/m2 and 1.4 g). An increase in growth was recorded in MA-DE (0.85 g/week) as compared to MA (0.26 g/week), and the specific growth rate (SGR) was 3.73 %g/day for MA-DE. Survival (81.0%) and production (1 029 kg/ha) in MA-DE were higher than in MA (75.3% and 842 kg/ha, respectively). Weekly growth showed no differences between both grow-out systems: MA-G = 1.07 and MA-DE-G = 1.02 g/week; however, SGR was lower in MA-DE-G (1.51 %g/day) than in MA-G (3.19 %g/day). Results indicate the lack of compensatory growth from MA to MA-DE, and from MA-DE to MA-DE-G, while partial compensatory growth was recorded from MA to MA-G. Taken into account this compensatory growth gain in juveniles, the culture of L. vannamei in MA at high density seems to be a good production strategy. Este estudio evaluó el crecimiento compensatorio y la producción de Litopenaeus vannamei en cultivos comerciales, durante el 2014, en fincas del Golfo de Nicoya, Costa Rica. Se compararon el crecimiento y la producción en tres sistemas a partir de una fase de precría (PC) con alta densidad de siembra directa de poslarvas (85/m2): a) precría-preengorde (PC-PE) en densidad media (23.3/m2) y peso inicial de 1.4 g, b) precría-preengorde-engorde (PC-PE-E) en baja densidad (8.6/m2) y peso inicial de 6.0 g y c) precría-engorde (PC-E) (9.4/m2 y 1.4 g). Se registró un aumento en el crecimiento en la PC-PE (0.85 g/semana) con respecto a la PC (0.26 g/semana) y la tasa específica de crecimiento (TEC) fue de 3.73 %g/d en la PC-PE. La sobrevivencia (81.0%) y la producción (1 029 kg/ha) en la PC-PE fueron superiores con respecto a la PC (75.3% y 842 kg/ha, respectivamente). El crecimiento semanal no mostró diferencias entre ambos sistemas de engorde: PC-E = 1.07 y PC-PE-E = 1.02 g/semana; sin embargo, la TEC fue inferior en la PC-PE-E (1.51 %g/d) con respecto a la PC-E (3.19 %g/d). Los resultados indican la inexistencia de un crecimiento compensatorio entre PC y PC-PE, así como entre PC-PE y PC-PE-E. Crecimiento compensatorio parcial se registró entre PC y PC-E. Tomando en cuenta la ganancia compensatoria en el crecimiento de los juveniles, el cultivo de L. vannamei en PC a alta densidad parece ser una buena estrategia de producción. Este estudo avaliou o crescimento compensatório e a produção de Litopenaeus vannamei nos cultivos comerciais, durante o ano 2014, nos viveiros do Golfo de Nicoya, na Costa Rica. Foram comparados o crescimento e a produção em três sistemas a partir de uma fase de pré-cria (PC) com alta densidade de recria direta de pós-larvas (85/m2): a) pré-cria – pré-engorda (PC-PE) em densidade média (23.3/m2) e peso inicial de 1.4 g, b) pré-cria - pré-engorda - engorda (PC-PE-E) em baixa densidade (8.6/m2) e peso inicial de 6.0 g e c) pré-cria - engorda (PC-E) (9.4/m2 e 1.4 g). Registrou-se um aumento no crescimento na PC-PE (0.85 g/semana) em relação à PC (0.26 g/semana) e a taxa específica de crescimento (TEC) foi de 3.73 %g/d na PC-PE. A sobrevivência (81.0%) e a produção (1 029 kg/ha) na PC-PE foram superiores com relação à PC (75.3% e 842 kg/ha, respectivamente). O crescimento semanal não mostrou diferenças entre ambos os sistemas de engorda: PC-E = 1.07 e PC-PE-E = 1.02 g/semana; entretanto, a TEC foi inferior na PC-PE-E (1.51 %g/d) com relação à PC-E (3.19 %g/d). Os resultados indicam a inexistência de um crescimento compensatório entre PC e PC-PE, assim como entre PC-PE e PC-PE-E. O Crescimento compensatório parcial foi registrado entre PC e PC-E. Levando em consideração o lucro compensatório no crescimento dos juvenis, o cultivo de L. vannamei na PC em alta densidade parece ser uma boa estratégia de produção.
