Evaluation of two mix cultures of white shrimp (Litopenaeus vannamei) with red tilapia hybrid and spotted rose snapper (Lutjanus guttatus) in intensive indoor brackish water tanks

Abstract

ABSTRACT. The aim of this study was to evaluate the growth performance and survival of the Pacific white shrimp (Litopenaeus vannamei) with red tilapia hybrid (Red Florida: Red Yumbo) and spotted rose snapper (Lutjanus guttatus), stocked at different densities in intensive brackish water mix-culture systems compared with monoculture of shrimp. The experiment, conducted in twenty-one plastic tanks (750 L) was set up to evaluate water quality, growth; production and survival of shrimp, tilapia, and snapper, for 60 days. Three replicates were assigned to seven treatments: After 30 day, initial densities were unfolded (shrimp = 50 ind m ). Feeding rate was adjusted at 5 and 10% of body weight d -1 for shrimp and fish, respectively. The shrimp-tilapia mix cultures produced the higher nitrogen and phosphorus in water concentrations. Significant lower survival values were obtained for shrimp (60.0 ± 0.6%) cultured with snapper and for tilapia (79.0 ± 3.1%) reared with shrimp. Mean final biomass for shrimp, tilapia and snapper were higher for the mix-cultures (2.04, 7.7 and 2.9 fold increase, respectively) with respect to their initial biomass. The mix culture system allowed an increase in total production with lower feed conversion ratios, thus contributing with the system sustainability.

The effect of tilapia Oreochromis niloticus addition on the sediment of brackish low-salinity ponds to white shrimp Penaeus vannamei farming system during the wet and dry season

“…Tilapia has been cultivated with a variety of fish and crustaceans under co-culture conditions mainly to improve production and have better environmental control of the farming system (Milstein & Hernández, 2017). The co-culture of tilapia with white shrimp Penaeus vannamei, has been shown to improve production and nutrient utilization in relation to shrimp monoculture, obtaining a better profitability and less environmental contamination (Sun et al, 2011;Bessa et al, 2012; Corresponding editor: Jesús Ponce-Palafox Barraza et al, 2013;Fitzsimmons & Shahkar, 2017;López-Gómez et al, 2017). It encourages the development of bacterial communities, fungi, algae and bioflocs of the native biota of the shrimp where the coculture is carried out (Fitzsimmons & Shahkar, 2017), as in brackish low-salinity ponds.…”
