Chlorophycean parasite on a marine fish, Sillago japonica (Japanese sillago)
چکیده انگلیسی


- A Japanese whiting (Sillago japonica) having numerous green-spots was caught.
- The green-spots were consisted by numerous coccoid algal cells.
- The alga was revealed to be belonging to Desmodesmus, Chlorophyta.

A green spotted Japanese sillago (Sillago japonica) was caught by a fisherman and brought to the laboratory for pathological inspection. The green spots were abundant on the lateral line and more extensively so within the mouth cavity. In both sites, green spots were embedded within the fish flesh and formed 2-3 mm dome-shaped colonies. SEM revealed these colonies to harbor numerous unknown cells with small, surface warts (ornamentations). Molecular analysis showed the cells were Desmodesmus (D. komarekii), a common freshwater coccoid green alga found in ponds and rivers worldwide. It is uncertain how the host fish came to be infected with the alga which was not merely attached externally but embedded within the flesh and inside the mouth cavity. This is the first case of parasitic form of coccoid green algae in marine fish and provides new insights into the variable nature of green algae.
