Physical and chemical aspects of the habitat of Macrobrachium americanum (Spence Bate, 1868) were measured between 10 and 12 h at the bottom of the sampling stations every two months in a year's cycle. Temperature ranged from 20.73 to 35.69°C; dissolved oxygen from 1.99 to 6.5 mg/l and from 10.6 to 150% of oxygen saturation; salinity from 0.2 to 1.03; pH from 7.25 to 9.19; Turbidity from 24.4 to 123.3 NTU; alkalinity from 141.8 to 358 mg/l and total hardness from 156.6 to 751.9 mg/l. Nitrates, total ammonia, copper, zinc, cadmium and lead were not detectable. Potassium ranged from 2 to 13 mg/l and iron was ≤0.8 mg/l. These findings will help the development of techniques for the production of M. americanum and suggest that this species is a stronger candidate for large-scale production than M. rosenbergii, where water alkalinity and total hardness are high.
