Mortality Count and Removal

Record total dead fish observed and removed from each production unit during morning inspection.

  • Have all floating and sinking dead fish been counted and removed from the unit today?
  • What is the total number of mortalities recorded for this unit today?
  • Does today's mortality rate exceed 0.5% of total standing stock?
  • Have mortalities been disposed of using an approved method (burial, composting, rendering)?
  • Has the cumulative 7-day mortality trend been reviewed and documented?

Water Quality Parameters

Measure and record key water quality parameters that directly influence fish health and mortality risk.

  • What is the current water temperature in this production unit?
  • Is dissolved oxygen (DO) at or above the minimum threshold for the species (typically ≥5 mg/L)?
  • What is the current dissolved oxygen reading in mg/L?
  • Is water pH within the acceptable range for the species (typically 6.5–9.0)?
  • Have ammonia and nitrite levels been tested and confirmed within safe limits?
  • Are any unusual odors, colors, or foam present in the water that may indicate contamination?

Clinical Signs and Behavioral Observations

Observe live fish for behavioral changes and external clinical signs indicating disease or stress.

  • Are fish exhibiting normal swimming behavior without listing, spiraling, or surface gasping?
  • Have any fish been observed with visible external lesions, hemorrhages, or ulcers?
  • Are fish feeding actively and responding to feed distribution within normal time parameters?
  • Have any moribund (near-death) fish been identified and isolated for examination?
  • Are gill coloration and opercular movement rate within normal parameters for the species?

Mortality Investigation and Gross Necropsy

Conduct gross post-mortem examination of representative mortalities to identify potential causes.

  • Have at least 3–5 representative mortality samples been selected for gross necropsy today?
  • Do internal organs (liver, spleen, kidney) appear grossly normal on examination?
  • Have necropsy findings been photographed and documented in the health record?
  • Have tissue samples been preserved and submitted to a diagnostic laboratory if cause is unclear?
  • Has the attending fish health veterinarian been notified of today's mortality findings?

Biosecurity and Disease Response Measures

Verify biosecurity protocols are in place to prevent disease transmission between units and farms.

  • Are disinfection footbaths at all unit entry points active and at correct concentration?
  • Is all equipment used in affected units being disinfected before transfer to other units?
  • Has fish movement between units been restricted pending investigation of elevated mortality?
  • Is access to production units restricted to essential personnel only during elevated mortality events?
  • Have all biosecurity breach incidents been documented in the site biosecurity log?

Feed and Medication Management

Confirm feed quality and any medicated feed use is properly documented for regulatory compliance.

  • Has feed consumption been measured and compared against expected intake for the unit?
  • If medicated feed is in use, has it been prescribed by a licensed veterinarian with a valid VFD?
  • Are withdrawal periods for any medications in use being observed and tracked?
  • Has feed storage been inspected for moisture, pests, or spoilage that could compromise quality?
  • Are feed lot numbers and delivery records current and available for traceability audit?

Reporting and Record-Keeping

Ensure all daily mortality data is recorded accurately and escalated appropriately per regulatory requirements.

  • Has today's mortality count been entered into the farm management information system or paper log?
  • Have any reportable disease signs been escalated to the state veterinarian or USDA APHIS?
  • Has the farm manager been briefed on today's mortality data and any significant findings?
  • Are all corrective actions taken today documented with date, description, and responsible party?
  • Please provide a summary of today's observations and any recommended follow-up actions.
