Asian Seabass, Lates calcarifer is one of the most economically important species that
is currently cultured in China, Australia and throughout Southeast Asia. Commonly this
species is exposed to the diversity of monogenean parasites that are known to be
pathogenic to this important aquaculture species. Barramundi is commonly infected
by Diplectanidae. The objectives of this study is to determine the morphological
characteristic of monogenean parasites especially attachment organs and to
determine the genus of monogenean that infected Lates calcarifer in cage culture of
Setiu wetland, Terengganu. In this study, 20 specimens of well mounted
monogeneans were chosen for identification. The monogenean on each mounted slide
was observed for morphological description and measurements made for identification
to genus. The important part of the morphological characteristic was drawn using
camera lucida and pictures captured by using Compound Advanced Research
Microscope. The Table Top SEM was used to scan the surface of monogenea. The
measurements and arrangement of attachment organs are the important part that
differentiates one monogenean genus and species from another. The genus of
monogenean parasites was identified by referring to expert and previous related
journals. There are many genus of Diplectanidae that have been identified through
their morphological characteristics in this study.
