Study Notes
Infectious Diseases
Viral Diseases
- Koi Herpes Virus Disease (KHVD): Caused by Koi Herpes Virus; characterized by gill infections, sunken eyes, and skin blisters; no effective treatment available.
- Lymphocystis Disease: Caused by Iridovirus; notable for cauliflower-like white swellings on body and fins; separation of affected fish recommended.
- Spring Viraemia of Carp Virus (SVCV): Caused by Rhabdovirus; symptoms include skin and gill hemorrhages, dark skin, and exophthalmia; prevention via good water quality and nutrition is crucial.
Bacterial Diseases
- Ulcer or Aeromoniasis: Caused by Aeromonas species; presents as skin lesions and open sores; treatment includes pond disinfection with KMnO4 at 5 mg/L.
- Fin and Tail Rot: Caused by Aeromonas and Pseudomonas species; symptoms include whitish margins and putrefaction of fins; antibiotic treatment recommended with terramycin or sulphadiazine.
- Columnaris Disease: Caused by Flavobacterium columnare; characterized by grayish patches and discolored fins; dip treatment in KMnO4 at 500 ppm for 2 minutes advised.
- Mycobacteriosis: Caused by Mycobacterium fortuitum; marked by emaciation and dropsy; treated with Oxytetracycline or Nifurpirinol in bath treatments.
- Dropsy: Caused by Aeromonas hydrophila; symptoms include distended abdomen and scale protrusion; treated with a dip in KMnO4 for 2 minutes and pond disinfection at 1 mg/L.
- Bacterial Gill Disease: Caused by Myxobacteria; presents with necrotic gill tissues; treated with bath treatment using alkyl benzalkonium chloride at 2 mg/L for 1 hour.
Fungal Diseases
- Cotton Wool Disease: Caused by Saprolegnia parasitica; identified by cotton wool-like outgrowths; treated with NaCl at 3-4%, KMnO4 at 160 mg/L for 5 days, and long-term bathing in methylene blue.
- Gill Rot: Caused by Branchiomyces species; signs include gill necrosis and discolouration; treatment involves NaCl baths and KMnO4.
Parasitic Diseases
- White Spot Disease: Caused by Ichthyophthirius multifilis; characterized by erratic swimming and visible white spots; treated with malachite green oxalate or sodium chloride solutions.
- Trichodiniasis: Caused by Trichodina species; symptoms include skin darkening and excessive mucus; treated with formalin or KMnO4.
- Oodinasis (Velvet Disease): Caused by Oodinium species; identified by gray patches on skin; treated with malachite green or formalin.
- Gill and Skin Fluke Infestation: Caused by Dactylogyrus and Gyrodactylus species; symptoms include faded gills and thick mucus layer; treatment involves Dipterex and formalin baths.
- Lernaeasis (Anchor Worm) Infestation: Caused by Lernaea species; exhibits emaciation and inflammation at attachment sites; treated with Dipterex and NaCl baths.
- Argulosis (Fish Lice) Infestation: Caused by Argulus species; marked by ulcerative lesions; treatment includes prolonged baths in trichlorphon or potassium permanganate.
Non-Infectious Diseases
Nutritional Deficiency Diseases
- Scoliosis and Lordosis: Caused by deficiencies in tryptophan and vitamin C, leading to spinal curvature; remedied by dietary supplementation.
- Pin Head Disease: Resulting from protein, carbohydrate, and lipid deficiencies; characterized by poor growth and sluggish behavior; necessitates nutritionally balanced feeding.
- Constipation: Related to imbalanced or low-quality diet; manifests as swelling and sluggishness; intervention includes feeding Daphnia as a laxative and salt treatment.
Health Management
- Health management in ornamental fish is critical due to high financial investments; knowledge of disease prevention is pivotal.
- Diseases arise from interactions between host, pathogen, and environment, categorized into infectious (spread through pathogens) and non-infectious (related to individual health issues).
