Compare one measured mesh opening with an externally verified range using the same convention—without selecting mesh from fish length or declaring gear legal.
Choose your path
Reconcile one measured net-mesh opening with an externally verified minimum–maximum range using one documented measurement convention without selecting mesh from fish length.
Align the actual net, section, tension, convention and units.
Enter measured mesh and the externally verified range using the same convention.
Sees distance to the entered boundaries without a selectivity recommendation.
Avoid mixing bar, square, knot-to-knot and stretched mesh.
Document the measurement method and repeat measurements under the required tension.
Can isolate measurement differences without claiming compliance.
Keep species, area, season, closures and protected-species measures current.
Check controlling federal/state/tribal/local rules and permit conditions externally.
Never uses the worksheet as authorization to possess or set a net.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Reconcile a completed knot-retention percentage from matching straight-reference and knotted mean peak-force records without inventing universal knot rankings.
Enter the actual opening and external boundaries in millimetres under the same bar, square, knot-to-knot or stretched-mesh convention and required tension. Mixing conventions makes the arithmetic meaningless.
The engine reports how far the measured opening is below the entered minimum, above the entered maximum or inside the entered range. It rejects a minimum greater than the maximum and never derives mesh from fish length.
Gear type, net section, species, area, season, closures, permits, marking, protected-species measures and current federal, state, tribal or local rules remain outside the comparison. No result predicts catch selectivity or authorizes use.

Enter the measured opening and externally verified range using one convention, then record its distance from the nearest entered boundary.
Confirm whether each record used bar, square, knot-to-knot or stretched mesh, the same net section and the specified tension before comparing numbers.
Use the worksheet only as one measurement record beside current permit, fishery, closure, protected-species and gear-marking requirements.
Document and use one required convention and tension for the actual net, section and all three entered values. Convert every measurement to millimetres first.
Check current species, fishery, area, season, closure, permit, protected-species, marking and possession rules. Mesh is only one part of gear authorization.
This worksheet reconciles one measured net-mesh opening with an externally verified entered range. It removes the unsupported fish-length formula and keeps measurement convention, fishery rules and gear authorization explicit.
