“…The actual effect of price variation varied between cases, where its effect was greater when poor growth parameters were entered into the model. Seed cost also had a significant effect in the NPV, revealing that it could be a determining factor for economic feasibility of scallop farming, this is also recognized in other attempts to model this industry (Adams et al, 2001). Some improvements to the performance of the model in the economic perspective could be to include seasonal variability, and stochastic processes that reflect real variation of prices and costs in the market.…”

ABSTRACT. Aquaculture farming is a complex system integrating several disciplines, including biology, engineering and economics, all which need to be correctly intertwined to have a profitable and environmentally sustainable activity. During the past recent years, scallop (Argopecten purpuratus) farmers in northern Chile have come to comprehend the hard way that aquaculture producers operate in a complex and dynamic environment where natural and economic factors are in constant change. Thus, to keep a profitable and competitive business in today's world, aquaculture farm managers are in need of relatively easy to use tools for efficient and timely decision making. Harvest size and time, mortality and growth rates, stocking rates, costs and market prices are important variables and parameters to monitor, where decisions with respect to their levels or values have to be made. In this context, non-linear and dynamic quantitative bioeconomic models should become valuable tools, for periodic decision making in the aquaculture business. This paper shows how to emulate Chilean scallop farming using a simulation model that mimics some of the industry's features. The model presented here focuses on a scallop aquaculture center that uses the common technology approach of pearl net and lanterns of the northern region of Chile, and analyses the farming strategies based on harvesting size. Also, these strategies were subject to variations in the parameters in order to identify patterns and asses the sensibility of the model to input values.

La acuicultura es un sistema complejo que integra varias disciplinas, incluyendo la biología, ingeniería y economía, las cuales deben ser correctamente entrelazadas para lograr una actividad rentable y ambientalmente sostenible. Durante los últimos años, los cultivadores del ostión del norte (Argopecten purpuratus) en Chile han comprendido de la peor manera, que las actividades de acuicultura operan en un entorno complejo y dinámico, donde los factores económicos y naturales se encuentran en estado de cambio constante. Para mantener un negocio rentable y competitivo, los administradores de los centros de cultivo necesitan herramientas que sean relativamente fáciles de utilizar para facilitar la toma de decisiones de manera eficaz y oportuna. Las tallas y tiempo de cosecha, tasas de mortalidad y crecimiento, densidades de cultivo, costos y precios de mercado son variables y parámetros importantes para controlar, donde son necesarias decisiones respecto de sus niveles y valores. En este contexto modelos cuantitativos dinámicos y no-lineales deberían convertirse en herramientas valiosas para la toma de decisiones, de forma periódica, en la industria de la acuicultura. Este trabajo muestra una alternativa para emular el cultivo del ostión en Chile, mediante un modelo de s...

“…Standard financial performance of aquaculture fisheries production was used (Adams et al, 2001;Brown et al, 2002;Goode et al, 2002;Fong et al, 2005;Liu & Sumaila, 2007;Sathiadhas & Najmudeen, 2004). Data was collected for both inshore and offshore production, income and cost were calculated annually, and then the net present value (NPV) was calculated for a ten year production period.…”
