For which the ingested food, defined at steady sate conditions through an energy balance, expressed as Scope for Growth terms is correlated to Specific Growth Rate through Monod model. Model give the specific growth rates as a function of environmental (seston concentration, water flow rates, fouling load), physiological (assimilation efficiency, metabolic expenditure, maintenance ration) and technological (stock density and retention efficiency of the culture system) variables. The growth rate model obtained is used to describe the growth of Venerupis pullastra seeds from data obtained under controlled conditions and simulate their behavior to changing scenarios. A full, logic and consistent description of the growth process obtained in agreement with mathematical, physiological and productive principles contribute a theoretic sustenance to aquacultural business and feasible to be applied to other species. 2014 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47931255005 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.1 Vol.49 |
