Monocultivo e policultivo do camarão Litopenaeus schmitti e do parati Mugil curema em sistema de bioflocos e água clara

Abstract

The aim of this study was to evaluate the monoculture and polyculture of white shrimp Litopenaeus schmitti and mullet Mugil curema in bioflocs system and clear water. The experimental design was completely randomized in a factorial arrangement (4x2) with four cultures systems (shrimps and fish) and two culture medium (clear water and bioflocs), with four replications: (M50/0) - monoculture L. schmitti density 50 m- 2; (P50/5) – polyculture L. schmitti and M. curema density 50 m-2 and 5 m2, respectively; (P50/10) – polyculture L. schmitti and M. curema density 50 m-2 and 10 m-2 respectively; (M0/10) - monoculture M. curema density 10 m-2. The polyculture of L. schmitti with mullet affected zootechnical performance of shrimp, however, L. schmitti juveniles showed better performance, for all analyzed indexes, when cultured in the bioflocs. The mullet in monoculture and polyculture with lower stocking density (5m-2) showed better final weight , weight gain and specific growth rate than mullet in polyculture with higher density (10m-2) and better performance when cultured in clear water. The bioflocs contributed significantly to shrimp juvenile growth, however fish did not present the same performance in bioflocs system.

Perspectivas de una producción sostenible en acuicultura multitrófica integrada (IMTA): Una revisión

“…El cultivo integrado de camarones y lisas (Mugil liza) en sistemas con Biofloc (BFT) ha demostrado tener éxito en la producción y calidad del agua (Melo et al 2016). El género Mugil tiene potencial para sistemas de cultivo integrados, ya que se alimenta en el nivel trófico más bajo (detritos, microorganismos, agregado de algas, bacterias, ciliados, rotíferos, nemátodos) de la superficie de sustratos como rocas o plantas (FAO 2006(FAO -2018Lupatsch et al 2003;Mondal et al 2015;Odum 1970;Rao y Badu 2013).…”
