Description:

The eggs of most dactylogyrid and diplectanid monogeneans that infect Acanthopagrus australis are tetrahedral. The adults of larger species deposit more eggs per worm on average in 24h in vitro: Lamellodiscus major (31.7 eggs) = Allomurray-trema rohustum (31.6 eggs) > Haliotrema spariensis (9.6 eggs) > Lamellodiscus squamosus (3.2 eggs). The eggs of L. squamosus (55.9 pm) and H. spariensis (56.4 pm) are smaller than those of L. major (66.1 pm) and A. robustum (63 pm). These eggs are normally shed into the water column. On the other hand, the eggs of Lamellodiscus acanthopagri are a modified T-shape (97.6 pm) and are attached to the gills by a sclerotised, thom-like filament. 1’he parasite can auto-infect the host, but has a low fecundity (0.05 eggs), possibly to prevent lethal parasite burdens.
