Larval mycosis in Penaeus monodon
(University of the Philippines, Los Baños, 1979)
A phycomycetous fungus, presumably a Lagenidium, was observed to infect Penaeus monodon larvae. Monitoring of the hatchery in 1976 and 1977 showed that it occurred in 35 out of 51 and 22 out of 37 runs, respectively. So ...
