Compensatory growth of Malaysian prawns reared at high densities during the nursery phase

Abstract: -The objective of this work was to verify the occurrence of compensatory growth in Malaysian prawn (Macrobrachium rosenbergii) reared in pens, after being stocked in cages under high densities during nursery phase. The experiment was carried out in 0.5 m 2 cages and 2-m 2 pens set in natural bottom pond with 2,400 m 2 . Prawn post-larvae (PL) with an average weight of 0.026 ± 0.012 g (nursery phase) were initially stocked in 16 cages at the densities of 50, 400, 800 and 1,200 PL m -2 . Sixty days later, prawns… Show more

“…The good results found in the present study are probably related to the biofilter efficiency and the establishment of bacterial colonies in the biofloc system. Marques and Lombardi () observed lower survival rates for the same species, ranging from 64.6 to 69.8%, in net‐pen production systems with postlarvae stocked at densities from 50 to 1200 m −2 .…”

“…In the Pacific white shrimp Litopenaeus vannamei the compensatory response with complete catch-up was achieved through the improvement of feed efficiency by Zhu et al (2014) [ 37 ], and in the absence of improved food efficiency by Wasielesky Jr. et al (2014) [ 38 ], but hyperphagia was not measured in both cases. In the Malaysian prawn Macrobrachium rosenbergii , the compensatory response with partial and complete catch-up was achieved through the improved food efficiency, but hyperphagia was not measured [ 39 , 40 ,]. Nevertheless, narrow-clawed crayfish Astacus leptodactylus could fully compensate growth, but no food efficiency improvement was observed, and hyperphagia was not measured at this time [ 41 ].…”

“…Este parámetro ha sido una de las mayores limitantes del cultivo en alta densidad en los sistemas de maternidad o precría tanto en camarones marinos (Cervais & Zeigler, 2013) como en langostinos de agua dulce (Marques & Lombardi, 2011). En cultivos superintensivos utilizando sistemas de biofloc los crecimientos han sido superiores (0.36 g/semana) a 30°C (Hostins et al 2015).…”

“…La TEC se redujo a menos de la mitad y la conversión alimenticia aumentó considerablemente en la PC-PE-E con respecto a la PC-E. La mayor tasa de crecimiento y la mejor eficiencia en la utilización del alimento en la PC-E pudieron ser el resultado de la ocurrencia de un crecimiento compensatorio parcial en esta fase producto de la drástica disminución en la densidad de siembra al pasar de 85.0/m 2 en la PC a 9.4/m 2 en esta fase. La influencia del tamaño de siembra (1.4 g en la PC-E y 6.0 g en la PC-PE-E) también parece mostrar una relación inversamente proporcional con la tasa de crecimiento como ha sido encontrado en langostinos de agua dulce (Marques & Lombardi, 2011). Una mayor eficiencia en la utilización del alimento y por lo tanto conversiones alimenticias más bajas han sido atribuibles al crecimiento compensatorio en peces (Dobson & Holmes, 1984).…”
