Contra-indications, warnings, etc
Vaccinate only healthy fish. Do not use if there are any signs of furunculosis or IPNV disease in the fish. It is recommended that all fish within the stock population are vaccinated in order to reduce infection spread.
Do not use in fish selected for broodstock.
Appetite may be reduced for up to 13 days following administration of the vaccine.
Vaccination may cause some degree of visceral adhesions within the peritoneal cavity, a characteristic of vaccines that incorporate an oil adjuvant. Adhesions may be moderate or even severe if vaccine is not properly delivered into the body cavity. Peak occurrence of side effects in correctly vaccinated fish are typically observed 3 to 6 months post sea transfer. Melanisation of viscera and muscle may also occur.
Observation of a sample of fish from a field study indicated the occurrence of mild (>93%; not noticeable to the layman) and moderate (<7%) adhesions at 6 months post sea transfer.
The user should note that physical and environmental conditions pre-vaccination, at the time of and post-vaccination influence the side effects seen in fish from site to site. These conditions include fish size, health, and condition, water temperature, correct vaccination practice including including handling and stress pre and post vaccination.
Short term (21 days) safety in 20g fish given double the recommended dose has been demonstrated. The severity of long term lesion development in 20g fish receiving a double dose of vaccine has not been evaluated.
