Spring Viremia of Carp Virus (SVCV) Diagnostic Protocol
Spring Viremia of Carp Virus (SVCV) is an important pathogen affecting fish in the carp family, with infected fish showing symptoms such as lethargy, reduced swimming activity, darkened body color, protruding eyes, abdominal swelling, and anal redness. SVCV is mainly transmitted through water, with infected fish and asymptomatic carriers excreting the virus through feces, body fluids, etc. This can lead to significant economic losses.

Koi Herpesvirus(KHV) Diagnostic Protocol
Koi Herpesvirus (KHV), also known as Cyprinid herpesvirus 3 (CyHV-3), is a virus that poses a significant threat to the koi and carp aquaculture industry. Early signs of infection may include hemorrhage, loose scales, anal swelling, sunken eyes, and later stages may show depression, sluggishness, skin and gill bleeding, and excessive mucus production. KHV mainly spreads through water, with virus and viral DNA detectable in fish secretions and feces.

Goldfish Hemorrhagic Virus (CHV) Diagnostic Protocol
Koi Herpesvirus, also known as Cyprinid Herpesvirus 3 (CHV3), is a virus that affects koi and other cyprinid fish species. It primarily targets the fish's hematopoietic organs, causing organ necrosis and a decline in immune function, which can lead to massive mortality in severe cases.

Diagnosis Protocol for Necrotizing Hepatopancreatitis
Necrotizing hepatopancreatitis (NHP) is a severe disease typically found in aquatic animals like shrimp but can also affect humans. It is characterized by necrosis of the hepatopancreatic tissues, which can lead to host death. Bacterial infection is a significant cause of NHP, hence accurate and rapid bacterial diagnosis is crucial for treatment and management.

Gudgeon Novirhabdovirus Diagnostic Protocol
Siniperca chuatsi rhabdovirus (SCRV), also known as Gudgeon rhabdovirus, is a virus that mainly affects the snakehead fish (Siniperca chuatsi) and belongs to the Rhabdoviridae family. SCRV S3 exhibits strong pathogenicity to zebrafish (Danio rerio), with mortality rates of 53% for blue zebrafish and 73% for red zebrafish at 28°C.

Diagnosis Protocol for Infectious Hypodermal and Hematopoietic Necrosis Virus
Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is an important pathogen affecting the shrimp farming industry. It is a microsporidian parasite that primarily infects shrimp's subcutaneous and hematopoietic tissues. Symptoms of IHHNV infection in shrimp may include slow growth, small size, and incomplete shell development, known as Runt-deformity syndrome.
