Resumen:
This study reports for the first time the pinfish, Lagodon rhomboides,
as a host of the isopod Cymothoa excisa, and shows the influence of
parasitism in the morphometric growth of the pinfish obtained from La
Carbonera, a tropical coastal lagoon on the northwestern coast of the
Yucatan Peninsula, Mexico. A total of 448 pinfish were collected between
April 2009 and March 2010. Twenty-eight individuals were found to host
the parasite, with a prevalence of 6.2%. Additionally, we obtained the
length-weight relationships (W= a Lt(b)) between individuals with
parasites (a= 0.0005; b= 2.31) and those without (a= 0.00003; b= 2.91).
Parameters a and b differed between groups (p< 0.05). The population of
L. rhomboides is affected by the presence of the isopod parasite, C.
excisa; differences in the length-weight relationship indicates that C.
excisa is a risk factor for this and other fish species in the study
area.
