Bio-security Procedures for Fisheries Inspection of Marine Fish
Farms
Background
The Provincial Fisheries Act permits Inspectors to enter
premises and/or pass over private property without being liable for
trespass for inspection of farm sites as specified in the Act. The
purpose of this protocol is to ensure that inspectors are aware of
the fish health and disease implications arising from the movement
of personnel, boats, equipment and other materials that could result
in the inadvertent transfer of pathogenic agents between fish farm
sites and/or companies. The protocol is designed to minimize the
risk of compromising the health of farm sites yet enable Inspectors
to perform inspection duties as required.
BC Fisheries has an obligation to ensure that their actions do
not increase the risk of transmission of salmon diseases between
farm sites. As such these criteria should be considered as a minimal
standard. Industry may have more stringent or additional protocols
to deal with specific concerns that inspectors must follow.
Compliance with these additional company procedures will further
reduced risk of disease transmission.
Investigations related to possible violations or complaints
require no formal advance notice to the company. In this case,
Inspectors should attempt to limit inspection to one site or a
limited number of sites thus reducing the potential for disease
transmission between sites.
Rationale: Transmission of disease agents can occur
through fomites (equipment, boots, boats, sampling gear etc.),
personnel visiting the sites or abiotic elements such as air and
water. To reduce the risk of transmission of disease agents between
sites, strict disinfection procedures and bio-security protocols
should be followed.
Notification for routine site inspections
For routine site inspections, site visits for
collection of samples or other scientific/project based reason,
Inspectors should provide the company in question 48 hours notice
prior to the visit. The Inspector should ask the appropriate
personnel, preferably the Area/Site Manager or Fish Health Manager
for that company, if there is a particular order with which sites
should be inspected. Any particular fish health concerns that a
company may have where site access should be limited (example algae
bloom, disease concern) can be addressed at this time.
Wherever possible, efforts should be made to inspect only sites
within one company per day to avoid the potential transfer of
disease agents between companies.
Investigations related to possible violations or complaints
require no formal advance notice to the company. In this case,
Inspectors should attempt to limit inspection to one site or a
limited number of sites thus reducing the potential for disease
transmission between sites.
Rationale: Younger fish first introduced to sea sites may be
naive and more susceptible to potential pathogenic agents than older
fish. To reduce the potential risk of transfer of disease from older
fish to younger naive stocks or transmission of agents to valuable
broodfish stocks, farms will often set out an order in which sites
should be inspected. If there is a fish health concern at a
particular site (example: an algae bloom or a disease present that
has not been identified at another site), Inspectors should ensure
that site is inspected last. No additional sites should be visited
prior to complete disinfection of the boat and bilge.
Disinfection procedures prior to site inspection
All boats, safety gear, personal gear, protective clothing,
raingear and boots must be disinfected and clean prior to site
visit. Boots and other personal gear should be sprayed or otherwise
scrubbed with a clean solution of iodine (examples: betadine,
ovadyne or wescodyne), Savlon, or Virkon diluted in water as per the
label instructions for equipment disinfection.
Boats and other gear should be free of visible dirt and organic
matter. Boats should be cleaned and bilge disinfected with mild
chlorine or bleach solution prior to site inspections and, if
possible, between companies. Bilge water and pumps should not be
operated in the vicinity of farms.
Disinfection procedures during site inspections
Footbaths should be available for disinfecting boots at all sites
at designated docking points. In the event no footbath is
visible/available, Inspectors should have on board the boat
equipment for disinfection of boots between sites. This should
include a spray bottle with a dilute solution of disinfectant or a
plastic tote or bucket with scrub brush and disinfectant.
Inspectors who are in contact with fish, fish feed, moralities
and related equipment during a site visit should disinfect all
personal gear and equipment and wash hands thoroughly.
Disinfection procedures after site inspections
All equipment and personal gear should be thoroughly disinfected,
cleaned and dried between inspections with a dilute solution of
Iodine, Savlon, Virkon or other cleanser recognized as effective
against fish pathogens.
