Experimental infection was conducted in the eggs and larvae of the swimming crab, Portunus trituberculatus, and the mud crab, Scylla serrata, through inoculation with zoospores of seven fungal strains belonging to the order Lagenidiales, which were isolated from eggs or larvae of these crabs cultured at Tamano Station of the Japan Sea-Farming Association, Okayama.<br>Fungal infection occurred in eggs and larvae as a result of inoculation with 102;-103; zoospores/ml and the water temperature influenced the infectivity of each strain. Judging from the infection rate, the pathogenicities of four strains belonging to three genera, Haliphthoros, Lagenidium, and Atkinsiella, were high. The fungal infection rate of the eggs decreased as their developmental stage progressed, and newly hatched larvae were most susceptible to fungal infection of all the different larval stages. Thus, it was thought that zoospores released from the infected eggs of an ovigerous female in a hatching tank caused fungal diseases in newly hatched larvae in the rearing tank. Consequently, to control the occurrence of fungal diseases in larval rearing tanks it is necessary to inhibit the transmission of the fungus from eggs to hatched larvae.
