Comprehensive Statistical Atlas of Diseases in Shrimp (Penaeid and Other Farmed Species)
This scientific reference provides an in-depth compilation of infectious diseases, non-communicable diseases, parasitic infections, nutritional and vitamin deficiencies, systemic illnesses, and cancers affecting marine and freshwater shrimp species (e.g., Litopenaeus vannamei, Penaeus monodon, Macrobrachium rosenbergii). Disease data is structured by organ systems with dedicated comparison tables for each, following veterinary and epidemiological standards.
Each disease entry includes:
- English & Latin Name of Disease
- Etiological Agent (virus [enveloped/non-enveloped, structure], bacteria [Gram +/−, morphology], fungi [structure], parasites [structure])
- Organs Affected or Systemic
- Lesions or Pathologies
- Typical Age or Developmental Stage at Infection
- Animal Demographics (young, adult, male, female, gravid, incubation, brooding)
- Season of Occurrence
- Estimated Survival Rate
- Treatment (active pharmaceutical ingredient)
- Vaccination (vaccine name and type, where applicable)
