Blood parameters and parasitic load in Sardinops sagax (Jenyns, 1842) from Todos Santos Bay, Baja California, Mexico

ABSTRACT: Some studies have characterized and evaluated the parasitic load of the Pacific sardine. However, there are few studies related to its physiology and parasites load. This study aimed to evaluate the blood parameters and the abundance of helminth parasites of sardines obtained from two samp...

This study aimed to evaluate the blood parameters and the abundance of helminth parasites of sardines obtained from two samples from Todos Santos Bay during autumn 2013.

The relationship between parasite abundance and blood parameters, based on the results of this study, it is not clear due to the low parasitic load.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Valparaíso.
