Two new records of Dactylogyrus Diesing, 1850 (Monogenea: Dactylogyridae) from cyprinids fishes farmed in Cuba

Abstract

Two monogeneans species were collected from gills of Labeo, Labeo rohita (Hamilton, 1822) and silver carp, Hypophthalmichthys molitrix Valenciennes, 1844 of four localities in the country: "La Sierpe" Fish hatchery and Zaza reservoir (Sancti Spíritus province); "Carlos Manuel de Céspedes" Fish hatchery (Santiago de Cuba province); and in the Aquaculture Technologies Company, EDTA (Havana province). The two species were identified according to their morphological characteristics and morphometric measures as Dactylogyrus labei Musselius and Gussev, 1976 (Gussev, 1976) from L. rohita; and Dactylogyrus hypophthalmichthys Achmerow, 1952 from H. molitrix. The collected parasites were set in ammonium-picrate and glycerin solution, and mounted in gelatin glycerin. Drawings, digital images and morphometric data were presented for each species. These new monogeneans records for Cuba also represent a new world geographical location.
