Resumen
GONZALEZ-ORTIZ, Laura et al. Spatial and seasonal variation of shell infested by Polydora sp. (Spionidae: Polychaeta) on the lion's paw clam (Nodipecten subnodosus) in the lagoon Ojo de Liebre, Baja California Sur. Rev. Mex. Biodiv. [online]. 2017, vol.88, n.4, pp.845-852. ISSN 2007-8706. https://doi.org/10.1016/j.rmb.2017.10.017.
In this study we evaluated the degree of infestation of Polydora sp. in Nodipecten subnodosus (lion's paw scallop). This research was carried out in laguna Ojo de Liebre, Baja California Sur, Mexico, quantifying the damage and growth of the clam for three years. A total of 10 samplings were carried out between January 2013 and October 2015, collecting 30 organisms by sampled at the banks Zacatoso, Chocolatero, El Dátil and La Concha. There were between 0 and 13 blisters per shell, 1.77 bisters shell-1 on average. The number of blisters was higher in the clams of the banks Chocolatero and Zacatoso, while in the banks El Dátil and La Concha, not only did the infestation decrease, but the variation intervals were smaller. Banks with smaller clams also recorded the largest number of blisters, mainly in Chocolatero. Although the maximum number of blisters occurred in January 2013, May 2014 and March 2015, the overall trend was for a reduction in polychaete infestation and clams over the length of study time.
