Length-weight relationships of three cladoceran species from a tropical reservoir in Mexico

We collected the three dominant cladoceran species from Valle de Bravo, a 1,730 ha drinking water reservoir in tropical Mexico and found a direct positive relation between carapace length (Y in mm) and the dry weight (X in mg) for all the three species. For Daphnia laevis, the relationship was In Y = -2.51 + 0.86 In X; for Chydorus sphaericus, In Y = -21.00 + 4.16 In X; and for Bosmina longirostris, In Y = -8.16 + 1.85 In X.
