Carga parasitaria del ostión de placer Crassostrea corteziensis en invierno y su importancia para la producción en el Estado de Sinaloa, Oyster production in Mexico shows an increasing trend, however, even in the state of Sinaloa were a local fishery and the incipient cultivation of pleasure oyster Crassostrea corteziensis exist and even thought environmental conditions are ideal, the production is low and unstable. In this sense, promoting its production represents an alternative to fishing communities as it is also, awell-known specie and it is appreciated by consumers. The promotion of this activity with solid bases, including sanitary aspects, in particular determining the types of parasites that can put production at risk is essential. It is known that cultivation practices increase the possibility of disease occurrence, due to densely grouping of populations in small areas and in occasions batches are freely transferred without health certification from one place to another, this greatly facilitates the spread of parasites and diseases. In the present work, the parasitic load in C. corteziensis was determined at different winter seasons in the coastal lagoons Río Fuerte (north), Las Puentes, Cospita (downtown) and Teacapán (south) situated along the state. The collection of organisms was conducted in the winter seasons from November 2011 to March 2012 and November 2012 to March 2013. In each lagoon approximately 30 oysters of commercial size were collected. Fresh analysis was performed on the soft body of the oyster, as well as histopathological analysis, to determine the parasitic load. Additionally complementary molecular analysis (PCR and in situ hybridization) were conducted to confirm the identity of Perkinsus marinus. The detected parasites were Rickettsia-like-bacteria, P. marinus, Nematopsis-like protozoans, Ancistrocoma-like protozoans, trematode cysts and copepod Pseudomyicola spinosus. The parasitic load of C. corteziensis was similar in the majority of localities studied during the two winter seasons, this indicates uniformity in the parasitic load independently of the particular characteristics of each lagoon, with the exception of the trematode cysts that were only found in the north and center of the state. Among the parasitic load, P. marinus represents the species of most interest because it is the causing agent of Perkinsosis, however, its prevalence and intensity were low possibly due to the conditions of this season which are not favorable for the development of the organism. The obtained results are also similar to reported results from other studies in the area. The identity of P. marinus was confirmed and it proved to be the same variety as the one found in the state of Nayarit, also its location in the tissues was similar. An annual or interannual surveillance of the parasitic load is recommended, that would allow the knowledge of the fluctuations throughout time in the pleasure oyster C. corteziensis
