The overall results are given in Table 2. Shrimp yield reached production rates as high as 3.23 kg/m2/yr with a mean of 2.36±0.76 kg/m2/yr, and seaweed production reached rates as high as 23.70 kg/m2/yr with a mean of 17.47±5.71 kg/m2/yr. Fig. 1 shows that it was possible to promote K. alvarezii growth inside cages, although the weight increment had been low in this experiment.
