If the Director determines that either destruction, quarantine or disinfection is required, he shall issue a written order to the owner or operator of the facility setting forth the steps for destruction and/or disinfection. Required disinfection of holding facilities will be completed at the owner's expense. If the owner disagrees with the Division's determination he shall have the right to appeal the decision to the Wildlife Commission provided notice of such appeal is given to the Director within seventy-two (72) hours of receipt of the order.

2. Regulated Disease Agents

a.Myxobolus cerebralis (Whirling Disease - WD)

1.Myxobolus cerebralis testing

a. At the time of the annual inspection for whirling disease certification, all facilities in Colorado or facilities importing fish into Colorado shall be tested using either of the two methodologies listed below.

1. Spore Concentration Technique: The facility shall provide at least one lot of live salmonids (minimum lot size of 260 fish) for whirling disease testing. As a screening procedure, fish shall be tested for the presence of Myxobolus cerebralis using a spore concentration technique ("SCT"). Minimum sample size of lots in aggregate shall be determined at the assumed prevalence level of 5% with 95% confidence.

a. Any negative finding will be conclusive for the absence of Myxobolus cerebralis.

b. Any positive finding will be presumptive for the presence of Myxobolus cerebralis. All presumptive SCT findings shall be confirmed by PCR. PCR results shall be conclusive as to the presence or absence of Myxobolus cerebralis.

2. Polymerase Chain Reaction (PCR) Technique: As an alternative to SCT, susceptible salmonids held at least 4 months in the water supply may be tested by PCR. A positive finding in such instance shall be considered presumptive for the presence of Myxobolus cerebralis. Confirmation shall be determined by a second PCR conducted by a different laboratory.

b. Sample size - for the purpose of annual inspections for Myxobolus cerebralis, the minimum sample size for determination of prevalence shall be sixty susceptible fish per water supply in a fish production facility.

c. Stocking from facilities which are presumptive for Myxobolus cerebralis.shall comply with the provisions of release of Myxobolus cerebralis positive fish during confirmatory testing. PCR tests for presumptive positives will be the highest priority for testing and every effort will be made to complete the test within 21 days.

d. For the purpose of conducting confirmatory testing, should it become necessary, at least 100 fish from each lot tested, with at least 200 total fish from tested lots, shall be held at the facility for up to 3 weeks after the initial inspection date.

e. Diagnostic or incidental observations of Myxobolus cerebralis by histology (presence of morphologically correct organisms within salmonid skeletal tissues) shall be presumed positive for the organism. Presumptive findings by histology shall be confirmed by PCR.

2. WD Negative Recertification: In order for the Myxobolus cerebralis status of a salmonid fish production facility to change from positive to negative, the owner and/or operator of the facility must complete all of the requirements of either aa or bb below:

a. Method 1 - Facility modifications and testing for Myxobolus cerebralis:

1. Render all originating water sources at the facility free of all fish and enclosed so as to prevent outside contamination by Myxobolus cerebralis.

2. Construct all rearing spaces and water conveyances of concrete, fiberglass, steel, or other manufactured impermeable materials that are not conducive to colonization by the alternate oligochaete host(s) of Myxobolus cerebralis.

3. Completely purge all sediments from rearing spaces and water conveyances at least once every two months.

4. After completion of steps 1 through 3, have the facility tested and found negative for Myxobolus cerebralis according to the following procedures and schedule:

a. A minimum of three hundred rainbow trout at least four months of age shall be designated as the sentinel lot and must be individually marked by a state fish pathologist. These fish will then be placed in approved rearing spaces selected for optimal exposure, at which time the exposure period shall begin.

b. Fish shall be collected and tested for Myxobolus cerebralis by a qualified fish pathologist during two inspections. A minimum of sixty fish from the sentinel lot, still bearing the previously placed tags, shall be included in each sample. The inspections shall occur at least ten months and at least fourteen months after the exposure period begins if a Spore Concentration Technique (SCT) is used. The testing shall occur at least 8 months and at least 12 months after the exposure period begins if Polymerase Chain Reaction (PCR) is used as the testing technique. The time frame for such testing by PCR may be shortened further if it is determined by the Director after consultation with the Fish Health Board that an additional reduction of the time frame for testing would present a negligible risk of not detecting the presence of Myxobolus cerebralis, after consideration of the following criteria:

1. Water supply(s).

2. Distance between water supply(s) and rearing spaces.

3. Nature of connecting pipes and conveyances.

4. Possibility of fish entering and exiting in water supply lines.

5. Nature and construction of rearing spaces.

b. Method 2 - Testing for Myxobolus cerebralis with partial or no facility modification.

1. A minimum of three hundred rainbow trout at least four months of age shall be designated as a sentinel lot, and must be individually marked by a qualified fish pathologist. These fish will then be placed in approved rearing spaces selected for optimal exposure to Myxobolus cerebralis, at which time the exposure period shall begin.

2. Fish shall be collected and tested for Myxobolus cerebralis by a qualified fish pathologist during four inspections. A minimum of sixty fish from the sentinel lots, still bearing the previously placed tags, shall be included in each sample. The inspections shall occur at least ten, fourteen, twenty-four, and twenty-eight months if SCT is used, or at least eight, twelve, twenty, and twenty-four months if a PCR is used as the testing technique after the exposure period begins. A second sentinel lot will be placed in the same rearing spaces after collection of the fourteen month sample for SCT or twelve month sample for PCR. The time frame for testing by PCR may be shortened further if it is determined by the Director that an additional reduction of the time frame for testing would present a negligible risk of not detecting the presence of Myxobolus cerebralis after consideration of the following criteria:

a. Water supply(s).

b. Distance between water supply(s) and rearing spaces.

c. Nature of connecting pipes and conveyances.

d. Possibility of fish entering and exiting in water supply lines.

e. Nature and construction of rearing spaces.

f. Nature and reliability of treatment technology.

g. System redundancy and back-up power supply.

3. Sampling in these inspections will be conducted at a minimum assumed prevalence level of five percent at the ninety-five percent level of confidence per lot at least eight months old; and at a minimum assumed prevalence level of two percent at the ninety five percent level of confidence for the facility as a whole.

c. Upon satisfactory completion of the requirements under either Method I or Method II, the State Fish Pathologist shall provide certification of negative Myxobolus cerebralis status.

3. Operation of Myxobolus cerebralis Positive Fish Production Facility.
