"Containment structure array"
means a group of containment structures physically attached to each other, or in the case of circular structures, up to a maximum of 60 m apart;
"Department"
means Fisheries and Oceans Canada;
"Disease"
means an abnormality of form or function and can be caused by a suite of infectious, noninfectious and inherent factors. Specifically:
"Evidence of escape"

"Facility"
means the collective structures used for the purposes of aquaculture, including but not limited to, net pens, walkways, barges, floats and living accommodations plus associated lines and anchors;
"Fish Health Event (FHE)"
means a suspected or active disease occurrence within an aquaculture facility that requires the involvement of a veterinarian and any measure that is intended to reduce or mitigate impact and risk that is associated with that occurrence or event;
"Fish health staff"
means the designated personnel, with veterinary oversight, responsible for: identifying, managing, and minimizing the impact of risk factors; making health-related decisions; and routine monitoring of health, lice and disease parameters;
"Harvest"
means removal of live fish for market;
"Harvest/transfer pens"
means pens that are secured for less than 90 days to the main cage array for the purpose of feeding, handling, holding, harvesting or moving fish;
"High slack tide"
means that point in time in any give location where the water depth has reached its maximum height (above chart datum) and any water movement has ceased, up until the current reverses direction;
"Incidental catch"
means any wild fish from within the facility caught during harvest, movement of fish between or within facilities, or net removal;
"Licence holder"
means the individual or corporation operating the facility;
"Marine mammal"
includes cetaceans, pinnipeds and sea otters;
"Mortalities"
means fish that have died within the containment structure array during a production cycle but does not include cultivated fish killed during harvest activities;
"Mortality event"
means:
  1. fish mortalities equivalent to 4000 kg or more, or losses reaching 2% of the current facility inventory, within a 24 hour period; or
  2. fish mortalities equivalent to 10,000 kg or more, or losses reaching 5%, within a five day period;
"Pathogen"
means a microorganism causing damage (pathology) in or on a fish. These include parasites, bacteria, rickettsia and viruses many of which are common and naturally present in the ecosystem;
"Peak biomass"
means the maximum biomass of finfish within a facility during a production cycle;
"Production cycle"
means:
  1. fish mortalities equivalent to 4000 kg or more, or losses reaching 2% of the current facility the period of time from stocking the containment structures to the time of harvest or removal of all finfish, prior to the facility being restocked; or
  2. fish mortalities equivalent to 4000 kg or more, or losses reaching 2% of the current facility for facilities containing broodstock, from the period of time immediately after a peak biomass up to and including the next peak biomass;
"Production site"
means a facility where fish of the same age class are entered at the same time, grown and harvested until the site is empty but may also have broodstock kept continuously on site in dedicated pen(s) for breeding purposes;
"Qualified individual"
means an individual employed by or contracted by an aquaculture corporation who possesses a combination of knowledge, expertise and experience necessary to complete a task;
"Sea lice abundance threshold"
means three motile Lepeophtheirus salmonis per fish as determined by a minimum sample of 20 live fish from three pens. In the event three pens can not be sampled, calculate the mean sampling average with data available;
"Tonnes (t)"
means 1000 kg;
"Transfer"
means the movement of live fish to or from a licensed facility or hatchery;
"Year class"
means the grouping of fish based on their time spent within the marine environment. Year class 1 represents a juvenile fish group that shares an approximate sea water entry date (e.g. within 4 months) plus the subsequent 12 months. Year class 2 refers to the fish group which remains in the sea water after the initial 12 month rearing period, but does not include broodstock.
