Salmonid enhancement program aquaculture licence - Appendix VIII - Licence conditions for net pens operated by enhancement facilities

This webpage is intended for informational purposes only.

1. Containment structures and net pen support systems

1.1 Facility operators shall ensure that equipment used at the net pen facility is designed, constructed and maintained to meet generally accepted standards prevalent in the aquaculture industry.

1.2 Containment structures shall be repaired or replaced with materials that meet or exceed the specifications prevalent in the aquaculture industry.

1.3 All net pen support system weights, anchoring equipment and other equipment shall be designed, constructed, installed and maintained in a manner as to prevent entanglement, catching, chafing or abrading any component of the containment system.

1.4 Above-water visual inspections of active net pen support systems including, anchoring-line buoy orientation and the general integrity of the anchoring system shall be conducted at all net pen facilities. Inspections shall be done daily or at a minimum, at every feeding.

1.5 Any irregularity or damage during the visual inspection must be corrected or repaired immediately.

1.6 A record of the visual inspection and any repairs carried out under this section must be made and a copy of the record must be retained at enhancement facility for not less than one year.

1.7 Anchoring equipment design must be compatible with the containment structure equipment and biophysical conditions of the location.

1.8 Anchoring equipment shall be repaired or replaced as required with materials that meet or exceed specifications generally accepted in the aquaculture industry.

1.9 Navigation marker buoys shall be deployed as required by Transport Canada.

2. Containment structure design, installation and maintenance

2.1 Primary net mesh shall meet or exceed 30 lb breaking strength.

2.2 Net mesh size shall be of a size to contain smallest fish in each pen.

2.3 Net pens shall be weighted at sufficient number of points to ensure the tension or weight is distributed evenly.

2.4 Sufficient weight or pressure shall be used to keep net panels taut.

2.5 Containment structures shall be stored in a manner that minimizes deterioration of the containment structure material.

2.6 Facility operators shall ensure that all tears found while handling or inspecting net pens in use or intended for use at any time are repaired immediately.

2.7 A complete visual inspection of the entire containment structure shall be completed for signs of abrasions, tears, or holes fish prior to the initial introduction of a new group of fish.

2.8 Any damage to the containment structure shall be repaired as needed.

2.9 After fish are released, nets must be washed, repaired and stored. Records of net use and servicing must be maintained for each net.

2.10 Net washing must be done in a manner that the activity does not damage fish habitat or shed fish pathogens and deleterious substances into fish habitat.

3. Predator control

3.1 Net pens shall be installed and maintained such that the upper edges are secured high enough out of the water to prevent mammalian predators such as seals or otters from coming in over the top edge.

3.2 Avian predator nets (bird netting) should be stretched over the net pens to prevent fish from being taken by birds.

4. Fish health

4.1 No fish shall be introduced to the net pens except in accordance with the Fish Health Management Plan (FHMP).

4.2 The FHMP of the enhancement facility shall be followed for the fish reared in net pens. Measures to control and monitor the presence of pathogens and pests in the net pens must be included in the plan

4.3 Mortalities must be collected on a regular basis to ensure conditions set out in Section 5.5 to 5.7 of Part C of this licence are met.

4.4 Water quality in the area of the nets must be monitored before fish are transferred to the net pens and while the fish are reared in the pens to ensure the biological requirements of the fish are met.

5. Antifouling

5.1 All anti-fouling coatings on net pens must be in compliance with accepted industry standards.
