Description |
The development of intensive shrimp culture and the upgrading of traditional shrimp farm have created the need for more hatchery seeds. Though hatchery production of shrimp seeds was successful, there is every chance that the seeds will be affected by infectious and noninfectious diseases. The shrimp larvae are susceptible to bacterial diseases like bacillary necrosis, larval necrosis, larval luminosis and juvenile vibriosis and generally greatest problem is met in the warmest months (Karunasagar et al., 1994) The impact on the host is systemic infection of the soft tissues of larvae resulting in tissue luminosis and necrosis (due to production of exotoxin by bacteria) and death. Diagnostic techniques like histology can reveal tissue necrosis and the presence of rod-shaped bacteria (usually slightly curved) within the tissues (Lightner,1983). It is possible to reisolate the luminous strains in Seawater Complex (SWC) agar from the tissues of infected larvae (Ruby and Nealson,1978;Lavilla Pitogo et al.,1990) |
