Abstract
ABSTRACT. The aim of this study was to evaluate the production of an aquaponic culture of white shrimp ( Litopenaeus vannamei ) and basil ( Ocimum basilicum ) using two sources of low-salinity water (1.7 g L -1 ): diluted seawater (DSW) and groundwater (GW) with zero water exchange at a stocking ratio of 4.9 shrimp per basil plant. Six aquaponic treatment systems were constructed: three individual aquaponic systems for DSW-basil, three for GW-basil, and a control (per triplicate) of basil only with hydroponic solution. Stock densities for shrimp were 75 PL m -2 and 16 plants m -2 for basil. With the exception of the yield in the shrimp culture (kg m -2 or t ha -1 ), no significant differences ( P > 0.05) were found for the final individual weight, survival, growth rate and feed conversion ratio between DSW and GW, whereas for basil, lower yields were found with DSW. No significant differences in the basil production between the control and the GW were found. Feed consumption per kg of total harvested basil were significantly lower ( P P > 0.05). The aquaponic culture of shrimp and basil using these two types of low-salinity water sources showed promising results. The estimates of both crop yields were comparable with those recorded in the literature and for commercial field crops from northwest Mexico.
