Study Notes
Environmental, Other Non-Infectious and Nutritional Diseases
- Aquaculture and aquatic animal medicine lecture by Jeryl Belle C. Rafanan, DVM
- Covers environmental, non-infectious, and nutritional diseases in fish and shrimp.
Outline
-
Introduction:
- Environmental diseases are caused by low dissolved oxygen, high ammonia, high nitrite, and natural/man-made toxins.
- Non-infectious diseases encompass environmental conditions, nutritional disorders, neoplasia, genetic defects, and poor husbandry.
-
Fish diseases associated with adverse physico-chemical properties of water:
- Gas bubble disease: Occurs when fish are exposed to water with supersaturated dissolved oxygen. Fish absorb the gas, and it's released, forming internal bubbles.
- Swimbladder stress syndrome (SBSS): Linked to swimbladder malfunction, often occurring after handling and partitioning of larvae.
- Asphyxiation/Hypoxia: Reduced dissolved oxygen levels in the water.
- Salinity stress: Changes in salinity, often due to high precipitation or evaporation, affecting oxygen solubility.
- Alkalosis: Water pH too high.
- Acidosis: Water pH too low, often due to acid rain.
- Sunburn disease: Caused by excessive ultraviolet irradiation from sunlight, especially in shallow, uncovered raceways.
-
Shrimp diseases associated with physico-chemical properties of water:
- Muscle necrosis: Bent/cramped tails or body cramp, incomplete molting, etc.
- Incomplete molting: Failure of exoskeleton to detach.
- Asphyxiation/Hypoxia: Reduced dissolved oxygen levels.
- Acidosis/Acid sulfate disease syndrome: Acidic water conditions.
- Black gill Disease: Various symptoms relating to gills.
- Red Disease: Specific symptoms/signs associated with disease.
- Chronic Soft-shell Syndrome (SHG): Indicates a chronic condition.
- Swollen hindgut Syndrome (SHG): Indicates a chronic condition.
Nutritional Diseases
- Possible nutrient deficiencies in fish:
- Signs: Anemia, anorexia, ascites, atrophy, cartilage abnormality, cataract, cloudy lens, clubbed gills, decoloration, and various other symptoms.
- Possible nutrient deficiencies: Folate, Inositol, Niacin, Pyridoxine, Riboflavin, vitamins A, B-12, C, B6, E, K, and other vitamins/minerals.
- Other symptoms and their associated nutritional deficiencies were mentioned in tables.
Diagnosis Techniques
- Environmental Diseases: Gross examination, histopathological/histochemical analysis, hematological analysis, analysis of water characteristics, and evaluation of management.
Other Related Topics
- Diseases associated with physical factors: Handling, transport, sorting, high stocking density, predation, and transport of fish, causing trauma and mortality.
- Neoplastic/Genetic diseases: Tumors – age, heredity, immunologic factors, carcinogen or irritants, trauma, oncogenic viruses; Genetic disorders – inherited factors (e.g., deformed spine, undeveloped operculum).
