Resumen
Inglés Español
The prawn shrimp Macrobrachium tenellum is a potential species for culture in México. The effect of ammonia on larvae was evaluated to provide basic information on safe levels for larviculture. A 72 h static assay was performed on 5 days old M. tenellum larvae. The nominal concentrations tested ranged from 2.89 to 185.48 mg NH4-N/L which represent 0.103 to 6.585 mg NH3-N/L at 20 g/L salinity, 28 ºC and pH 7.79. LC50 for 12, 24, 48 and 72 h were 2.939 ± 0.505, 0.749 ± 0.301, 0.477 ± 0.163 and 0.409 ± 0.068 mg NH3-N/L, respectively. These results suggest that M. tenellum exhibits a slightly higher tolerance to ammonia in the zoea stage when compared to most of the prawn and shrimp species.
