WHY PROPER HANDLING MATTERS

Every handling event is a stress event. Minimising contact time, using fish-safe materials and grading accurately all contribute to better survival rates, faster growth and healthier stock.

Stress & Slime Coat Damage

When fish are handled with coarse nets or bare hands, their protective slime coat is stripped away — leaving them vulnerable to bacterial infection, fungal colonisation and osmotic shock.

  • Slime coat is the first line of immune defence
  • Damage opens pathways for opportunistic pathogens
  • Recovery costs energy that should go to growth
  • Soft knotless mesh eliminates abrasion damage

Grading Accuracy & Growth

Size variation in a cohort leads to competitive feeding — larger fish dominate, smaller fish fall behind. Accurate grading produces uniform cohorts that feed efficiently and grow predictably.

  • Uniform cohorts reduce feed waste by 15–25%
  • Graded fish show consistent FCR across the batch
  • Adjustable bar graders size fish without manual chasing
  • Non-invasive sorting preserves skin integrity

Stock Counting & Auditing

Accurate stock counts are the foundation of feed budgeting, health forecasting and production planning — yet most operations still rely on manual estimates prone to significant error.

  • Automated counting eliminates human estimation error
  • Real-time data logging for inventory reconciliation
  • Gentle handling preserves fish condition during counting
  • Critical for sales grading and pond stocking records

Common Questions

HANDLING FAQ

Why does knotless mesh matter?

Knots in standard mesh abrade the fish's protective slime coat on every contact. Soft knotless mesh removes that abrasion point, keeping the first line of immune defence intact during transfers.

How does grading improve growth rates?

Mixed-size cohorts lead to competitive feeding where larger fish dominate. Accurate grading produces uniform cohorts that feed efficiently, show consistent FCR and grow predictably.

Do the MAG graders need tools to adjust?

No. The Fresh-Flo MAG graders use a manual adjustment system — bar spacing changes in seconds without extra tools or racks, and the graders float in both fresh and saltwater.

Why automate stock counting?

Manual estimates carry significant error that compounds through feed budgeting and production planning. An automatic counter eliminates estimation error and logs real-time data for inventory reconciliation.
