Fish Farm Predator Deterrent System Check Checklist [FREE PDF]

Predator intrusion at fish farms poses significant biosecurity, animal welfare, and production risks, and the management of protected predatory species such as great blue herons, double-crested cormorants, and otters is governed by the U.S. Migratory Bird Treaty Act (MBTA) and USDA APHIS Wildlife Services guidelines. BAP Best Aquaculture Practices and ASC Certification Standards require documented predator management programs that prioritize non-lethal deterrence, and facilities must maintain ex

  • Industry: Fish Farming
  • Frequency: Weekly
  • Estimated Time: 30-45 minutes
  • Role: Biosecurity Officer
  • Total Items: 36
  • Compliance: USDA APHIS Wildlife Services Depredation Order 50 CFR 21.47 (Cormorant), U.S. Migratory Bird Treaty Act 16 USC 703-712, BAP Best Aquaculture Practices Standard Issue 3.0 - Biosecurity Section 6, ASC Salmon Standard v1.3 Section 7 (Wildlife Interactions), USDA APHIS Aquaculture Biosecurity Guidelines (National Aquaculture Act 16 USC 2801)

Predator Activity Review

Review recent predator sighting logs and assess current predator pressure before inspecting physical deterrent systems.

  • Has the predator activity log from the previous 7 days been reviewed prior to this inspection?
  • Have any predator intrusion events or stock losses attributable to predation been recorded since the last inspection?
  • Have any protected species been observed within the facility perimeter during the past week?
  • What is the current predator pressure level assessed for this inspection period?
  • Have all required predator interaction reports been submitted to USDA APHIS Wildlife Services if lethal control was used?

Overhead Netting and Exclusion Systems

Inspect overhead netting systems covering raceways, ponds, and cages for structural integrity and absence of entry points.

  • Is overhead netting present and installed over all production areas designated to require bird exclusion?
  • Is the netting free from holes, tears, sagging sections, or gaps larger than 1 inch that would permit bird or otter entry?
  • Are netting support structures (poles, cables, tensioners) in good structural condition without corrosion, bending, or failure?
  • Has a photo inspection of the overhead netting system been completed and attached to this record?
  • Is access netting or panel netting at pond entry points secured and closed when not in active use?

Perimeter Fencing and Mammalian Predator Barriers

Inspect ground-level perimeter barriers designed to exclude otters, mink, raccoons, and other mammalian predators.

  • Is perimeter fencing intact around all pond and raceway production areas with no gaps, breaches, or undermining?
  • Are electric fence energizers (if used) operational, properly grounded, and delivering adequate voltage?
  • Are fence lines free from vegetation overgrowth, debris, or tree fall that could compromise the barrier or short electric fences?
  • Are gates and access points properly secured with predator-proof latching mechanisms?
  • Have any signs of predator digging, climbing attempts, or barrier breaching been observed along the perimeter?

Active Hazing and Non-Lethal Deterrent Devices

Verify that all active hazing devices including pyrotechnics, acoustic deterrents, and visual scares are operational and deployed correctly.

  • Are all installed acoustic deterrent devices (propane cannons, underwater acoustic deterrents) functional and activated on schedule?
  • Are visual deterrents (predator decoys, reflective tape, Mylar balloons, laser devices) in place and in good condition?
  • Is pyrotechnic hazing equipment (if used) stored safely, inventoried, and used only by trained personnel?
  • Has the hazing deterrent program been rotated or modified since the last inspection to prevent predator habituation?
  • Are all active deterrent device inspection and maintenance records current and filed?

Cage and Net Pen Structural Integrity

For cage or net pen operations, inspect the integrity of containment and predator exclusion components of each production unit.

  • Are all net pen or cage side nets free from tears, holes, or abrasion damage that could allow predator entry or fish escape?
  • Are anti-predator nets or collars installed around the perimeter of all net pens or cages?
  • Are mooring lines, anchor systems, and cage collars in structurally sound condition without excessive wear or corrosion?
  • Has an underwater inspection of net pen integrity been conducted within the required frequency per the farm's net inspection protocol?
  • Are predator incident alarm systems or CCTV monitoring systems covering net pen areas operational?

Mortality Management to Reduce Predator Attraction

Verify that fish mortality management practices minimize predator attraction and comply with biosecurity requirements.

  • Are dead fish removed from production areas at the required frequency (typically daily) to minimize predator attractants?
  • Are fish mortalities stored in sealed, predator-proof containers prior to disposal?
  • Is the fish mortality disposal method compliant with state solid waste or composting regulations?
  • Are daily mortality counts recorded and reviewed for unusual spikes that may indicate disease or predation-related losses?
  • Are feed areas and uneaten feed managed to prevent accumulation that could attract predators?

Corrective Actions and Compliance Documentation

Document all deficiencies identified during this inspection, assign corrective actions, and confirm regulatory compliance status of the predator management program.

  • Does the facility have a written Predator Management Plan approved by USDA APHIS Wildlife Services or equivalent authority?
  • Have all farm personnel responsible for predator management received documented training on non-lethal deterrence and MBTA requirements?
  • Are all permits or authorizations for any lethal predator control measures current, posted, and accessible on-site?
  • Have all deficiencies identified during this inspection been assigned a responsible party and target completion date?
  • Describe all deficiencies found during this inspection, corrective actions assigned, and any predator incidents requiring regulatory notification.
  • Has a photo record of all identified deficiencies been captured and attached to this inspection report?
