Abstract

In the family Majidae, there are several crab species with potential for cultivation, particularly in the genus Mithrax, which supports a commercial fisher in the Caribbean region. In this study we studied the effect of various diets on the survival of M. spinosissimus, by aplying six treatments in 150 ml and 101 liter containers with 100 ml and eight liters of filtered and sterilized water. The treatments were: 1.- Without food; 2.- Chaetoceros sp.; 3.Chaetoceros sp. + Rotífers; Chaetoceros sp. + Copepods; Chaetoceros sp. + Artemia and Chaetoceros sp. + Rotifers + Copepods + Artemia. Subsequently, in 1,000 L tanks with 600 L of sterile, filtered seawater, two treatments were applied: Chaetoceros sp. + Rotifers and Tetraselmis sp. + Rotifers for nine days, then utilizing a biomas of sarines and artemia with Enteromorpha sp. In the first case, higher survival was achieved in treatments two and three, and in the second case with Chaetoceros sp. + Rotifers and artemia biomass with Enteromorpha sp. Temperature ranged between 26-28°C, and the average salinity was 37%.
