Volume loss of an aquaculture net pen due to current speed and linear weight of sinker ring

Abstract

Volume loss of an aquaculture net pen due to current speed and linear weight of sinker ring Latin American Journal of Aquatic Research, vol. 43, núm. 2, mayo, 2015, pp. 309-314 Pontificia Universidad Católica de Valparaíso Valparaíso, Chile ). It was found that under the most severe condition, that is, the highest current speed and the lowest linear weight of the sinker ring (0.75 m s -1 and 25 kg m -1 , respectively), the volume loss with respect to initial undeformed net pen volume reached a maximum value of 53%. This occurred in the net pen firstly exposed to currents. Based on modeling results, a relationship between net pen volume loss due to the combined effects of both water current speed and linear weights of the sinker rings is proposed. Key words: net pen deformation, current speed, sinker ring, Chile. Pérdida de volumen de una jaula de cultivo por efecto de la velocidad de la corriente y del uso de anillo cortacorriente RESUMEN. El volumen interno de las jaulas es una variable relevante para el bienestar de los peces durante el proceso de engorda. En este trabajo se modeló un tren de balsas jaulas usando el programa de elementos finitos AquaSim®. Se analizó la influencia de tres velocidades de corriente con flujo uniform
