“…Yet lower costs of production for smaller individuals are not the case for all species. In shrimp, it was noted that a single long cycle of production resulted in greater profitability for the farmer than two shorter cycles per growing season [15]. While the efficiency of producing small animals is biologically constant across all species, the specific details need to be worked out for each species and production system.…”

Limiting Size of Fish Fillets at the Center of the Plate Improves the Sustainability of Aquaculture Production

North American dining customers like to have a singular large piece of protein in the center of the plate. When fish is the protein of choice, the portion size from many species is limited by the overall size of the fish. Therefore, for these species, the means to achieve a singular larger portion of "center of the plate" protein is to grow a larger animal. However, fish become less efficient in converting feed to protein as they age. A second option would be to provide two smaller fillets originating from younger, more efficient fish. Here, the sustainability ramifications of these two protein provisioning strategies (single large or two small fillets) are considered for three species of fish produced in aquaculture. Growth data for channel catfish (Ictalurus punctatus) produced in ponds, rainbow trout (Oncorhynchus mykiss) in raceways, and sablefish (Anoplopoma fimbria) in marine net pens, were modeled to assess the total biomass and overall food conversion ratio for the production of small, medium or large fish. The production of small fish added an additional 50% or more biomass per year for trout, catfish, and sablefish compared to the production of large fish. Feed conversion ratios were also improved by nearly 10% for the smaller compared to larger fish of each species. Thus, even though all of these species tend to be considered aquaculture species of low environmental impact (and hence "green" or sustainable options), the product form requested by retailers and served by chefs can further increase the sustainability of these species.

“…Con respecto a las fases de engorde, las sobrevivencias obtenidas cercanas al 85% pueden considerarse muy buenas y superiores a las obtenidas (76%) en Venezuela (Krummenauer et al 2010) con densidades similares de siembra. La similitud del crecimiento en ambas fases de engorde parece mostrar independencia del tamaño inicial sembrado cuando se utiliza una densidad de siembra muy parecida.…”

“…Este fenómeno se explica porque en octubre del 2013 aún dominaba una condición neutral con tendencia leve de calentamiento en todo el Pacífico ecuatorial (Alvarado, 2013). La supervivencia, el crecimiento y los rendimientos de producción se han reducido en otros países latinoamericanos, debido a las bajas temperaturas ambientales y del agua por efecto de los frentes fríos en esta época (Scura, 1995;Ponce-Palafox et al 1997;Krummenauer et al 2010).…”

“…Una conversión alimenticia de 1.6:1.0 como la obtenida en el ciclo largo puede considerarse excesiva para nuestras condiciones propias de manejo, aunque está dentro del rango aceptable (1.5-2.4:1.0) en otros países como Venezuela y Brasil con densidades similares de cultivo (De Donato et al 2005;Krummenauer et al 2010).…”

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.
