“…El tercer ciclo corto del año presentó una sobrevivencia inferior (67%), que se explica por la transición entre la época lluviosa y la seca (Valverde-Moya & Alfaro-Montoya, 2013). En términos generales, el rango de supervivencia (63-75%) en todos los ciclos fue similar al obtenido en Venezuela luego de 11 generaciones de 1990 al 2001 (59 a 76%) y ligeramente superior a los valores reportados (58 a 65%) en otros estudios, pero con densidades superiores de siembra (17 a 45/m 2 ; Sookying et al 2011).…”

“…El mayor crecimiento (0.98 g/ semana) en los ciclos cortos en relación con el ciclo largo (0.76 g/ semana) también pudo ser debido a una influencia positiva de la menor densidad de siembra, como se ha demostrado en otros estudios (Sookying et al 2011). Sin embargo, la tasa de crecimiento en el ciclo largo fue similar a las obtenidas (0.76 a 0.87 g/semana) en estanques grandes en Venezuela desde 1990 hasta el 2002 con densidades de siembra parecidas (De Donato et al 2005).…”

“…Estas productividades son superiores a las obtenidas en Brasil (1 962 kg/ha en 2 ciclos cortos consecutivos de 75 días cada uno y 1 322 kg/ha en un ciclo largo de 150 días) con una densidad de siembra de 10/m 2 (Krummenauer et al 2010) y en Texas (1 777 kg/ha/año) en condiciones semiintensivas de cultivo (Samocha et al 2004). Son similares a las obtenidas en Alabama con una densidad de siembra de 17/m 2 (2 660 kg/ha; Sookying et al 2011).…”

RESUMENEl objetivo del presente estudio es la evaluación de la productividad y la rentabilidad económica del cultivo comercial de camarones marinos en el Golfo de Nicoya, Costa Rica. El estudio se llevó a cabo en el 2013 en fincas comerciales localizadas en los sectores de Abangaritos de Puntarenas, Colorado de Abangares, Puerto Jesús de Nicoya y Lepanto de Puntarenas. Se sembraron 25.4 has en modalidad de 3 ciclos cortos y 24.6 has en modalidad de ciclo largo, siguiendo un plan de manejo convencional. La productividad en kg/ha/año fue superior en los 3 ciclos cortos (2 605 kg/ha/año) con respecto al ciclo largo (2 138 kg/ha/año). Los costos variables de producción fueron más altos en los ciclos cortos (US$ 8 389) que en el ciclo largo (US$ 6 783), debido a la utilización de dos tecnologías distintas de cultivo en cuanto a densidades de siembra, cosechas por año, tamaño del producto, precio en el mercado y recambios de agua. Los ingresos por concepto de ventas al pie de finca fueron más altos en los ciclos cortos (US$ 14 671/ha) que en el ciclo largo (US$ 12 281/ha). El estudio de sensibilidad económica sugiere la realización de 3 ciclos cortos en lugar de un solo ciclo largo, debido a la mayor productividad y rentabilidad (US$ 5 536/ha contra US $ 4 752/ha); sin embargo, la estrategia de producción no debe ser fija sino flexible para ajustarse al cambio, sobre todo del precio del producto en el mercado en esos momentos.Palabras claves: Decapoda, Penaeidae, Litopenaeus vannamei, cultivo comercial, camarones. ABSTRACTThe main objective of this study was to evaluate productivity and economic profitability of commercial culture of marine shrimp in the Gulf of Nicoya, Costa Rica. The study was conducted in 2013 in commercial farms located in Abangaritos de Puntarenas, Colorado de Abangares, Puerto Jesús de Nicoya and Lepanto de Puntarenas. A total of 25.4 ha in 3 short cycles and 24.6 ha in one long cycle were used, following a conventional management plan. Productivity in kg/ha/year was higher in the 3 short cycles (2,605 kg/ha/year) compared to the long cycle (2,138 kg/ha/year). Variable costs of production for the short cycles were higher (US$8,389) than those for the long cycle (US$6,783), due to the implementation of 2 different culture technologies concerning stocking densities, harvests per year, product size, market price and water exchange. Income from farm sales was higher for the short cycles (US$14,671/ha) than for the long cycle (US$12,281/ha). The economic sensitivity analysis suggests the implementation of 3 short cycles rather than one long cycle based on higher productivity and profitability (US$5,536/ha compared to US$4,752/ha); however, the production strategy must be flexible to adjust to changes, particularly regarding product market price at any given moment.

“…Replacement of fish meal with alternative sources of proteins from terrestrial animals or plants has been encouraged [6]. Additionally, the use of wild fish in the form of fish meal and fish oil as inputs for aquaculture feeds, relies on marine species that are renewable, but often overexploited for human use [7].…”

Three extruded diets were formulated and used to cultivate Macrobrachium rosenbergii prawns. For ninety days, the prawns were fed on the similarly balanced isonitrogeneous and isoenergetic diets, based on albumin and linseed (Linseed diet), on whey proteins concentrate (WPC) and soybean oil (Whey proteins diet), and on albumin and soybean oil (Control diet). Every thirty days, the shrimps were weighed and submitted to analyses. The results showed that the average body weights for the shrimps fed on the Linseed and Whey proteins diets were approximately sixty percent higher than for those fed on the Control diet. No significant differences were found for the protein content and the total lipid content in shrimps fed on the diets. However, the Linseed diet led to the lowest cholesterol level and improved the ratio between the sum of n-6 and the sum of n-3 fatty acids in the whole body of shrimps. WPC was used for the first time as a protein source for shrimp feeds, and may be considered as a component to be used in extruded diets for aquaculture. The results suggested that the experimental diets succeeded to provide shrimps with greater weight gain and nutritional value.

Poly‐β‐Hydroxybutyrate (PHB) Improves Nursery‐Phase Pacific White Shrimp Litopenaeus vannamei Defense against Vibriosis

This study assessed the effect of poly-β-hydroxybutyrate (PHB) on the growth, survival, and disease resistance of Pacific white shrimp Litopenaeus vannamei. A 20-d feeding test using 30-d-postlarval Pacific white shrimp (100 shrimp/ tank) tested three different diets: 0.3 g PHB/kg diet, 0.5 g PHB/kg diet, and commercial feed containing no PHB as the control. The feeding test was followed by a 10-d bacterial challenge test using Vibrio harveyi. After the feeding test, the highest average final body weight, specific growth rate, and total biomass (mean ± SD = 0.44 ± 0.28 g, 28.82 ± 2.08%/d, and 25.91 ± 7.19 g, respectively) were found in the 0.5 g PHB/kg diet group, while the 0.3 g PHB/kg diet showed the highest survival rate (67.00 ± 8.83%). After the Vibrio harveyi challenge test, both PHB diet treatments resulted in the same significantly higher survival rate (96.66 ± 4.71%) compared with the control treatment (70.00 ± 4.71%). The highest body weight gain during the challenge test was seen in the 0.5 g PHB/kg diet group. Total abundance of heterotrophic bacteria and Vibrio spp. was relatively similar for all treatments. Histopathological analysis showed that hepatopancreas samples from PHB-supplemented Pacific white shrimp showed decreasing tubular epithelial cell lesions as a result of Vibrio harveyi infection, suggesting that PHB protected the hepatopancreas of Pacific white shrimp from the destructive effect of Vibrio harveyi infection. Supplementation at 0.5 g PHB/kg significantly increased Pacific white shrimp survival and growth with or without Vibrio harveyi infection and, thus, has high potential for further use in Pacific white shrimp aquaculture.
