Abstract

The oyster is the organism but cultivated world-wide and Mexico place occupies 6º, with 50.000 mt annually. The 96% come from the Gulf of Mexico, where Tamaulipas is 4° national place, although this is not reflected in the extension of potentially cultured coastal lagoons, considering that represents the first place with 274.736 has. It is important to indicate that in the value of the production the Gulf represents the 65%, whereas the Pacific contributes the 35%, this must to that most of this production he is of culture reaching better prices by the confidence of the consumer towards these products. This work was made in Barra of the River Carrizo, Tamaulipas, during six months, and comprises of the project "Development of the Technology for the culture, purified, packaged to the emptiness in its shell and congealed of the oyster in the Gulf of Mexico", financed by the CONACYT. The organisms were seeded with stature average of 48,47 mm, weight average of 26,41 gr., and cultivated in: oysters baskets and bags in suspension, three densities different from sowing. The pursuit of the growth and mortality, were made by means of measures of stature, monthly weight and counts for each repetition, registering the environmental parameters of temperature, salinity and dissolved oxygen, the best results appeared in the method of oyster baskets, with a density of sowing of 160 oysters per basket; the organisms after 60 days reached a stature of 90,45 mm, with a 6,99 increase of mm/month, and mortality was of 10.6%. The results demonstrated that it is technically feasible to culture oysters in these waters.
