Available tools
- Catch Record Length Type Tag Tool Preserve explicit fish catch length transcription and measurement definition without converting length types.
- Catch Sample Selection Factor Tool Report explicit sampled-catch fractions without assuming random or representative sampling.

- Fish Condition Relative Weight Reference Tool Relative weight against an independently supplied length-specific reference mass, without selecting a species condition standard.
- Fish Egg Density Subsample Factor Tool Homogeneous sample-volume expansion followed by independently measured filtered-water volume normalization.
- Fish Finclip Tissue Parent Label Tool Link an explicit fish tissue sample to a supplied parent specimen and site label without identifying organisms.

- Fish Net Soak Time Unit Convert an explicitly recorded net soak duration to hours using fixed elapsed-time units.
- Fish Sample Preservation Shrink Factor Tool Separate caller-calibrated length and mass retention corrections; an isotropic mass-length relation is not imposed.
- Fish School Transect Density Term Tool Strip-area density with an explicitly supplied detection correction, without estimating school geometry or detectability.
- Fish Standard Total Length Gap Tool Calculate fish standard total length gap from explicit caller-supplied inputs.
- Fish Standardlength Bodydepth Ratio Tool Divide explicitly supplied fish standard length by positive body depth without inferring species, age or condition.
- Fish Survey Net Depth Span Tool Calculate an explicitly ordered survey-net depth span from a shared surface datum without estimating sampled volume.
- Fish Swimming Body Lengths Per Second Tool Calculate fish swimming body lengths per second from explicit caller-supplied inputs.
- Fish Tag Detection Gap Subtract explicitly recorded ordered fish-tag detection times without estimating movement between detections.
- Fish Tag Recapture Length Increment Tool Signed observed length increment with an explicit 365-day annualized rate, not an extrapolated biological growth curve.

- Ichthyological Voucher Preservative Label Tool Record an explicitly supplied fish-voucher preservative transcription without preservation recommendations or composition inference.
- Larval Fish Yolk Sac Volume Term Tool Supplied rotational ellipsoid-like shape factor times long diameter and squared short diameter; the geometry coefficient is explicit.
- Net Effort Missing Panel Budget Tool Calculate net effort missing panel budget from explicit caller-supplied inputs.
- Net Effort Time Area Term Tool Calculate net effort time area term from explicit caller-supplied inputs.
- Otolith Annulus Edge Status Token Tool Label an explicitly supplied otolith edge status without counting annuli or assigning age.
- Otolith Annulus Label Label an explicitly numbered otolith annulus without inferring fish age or annual periodicity.
- Otolith Edgeage Reference Offset Tool Increment-count bookkeeping with a supplied edge/reference convention, not biological age validation.
- Otolith Image Calibration Microns Pair Tool Scale one explicit otolith pixel length by supplied micrometers per pixel without detecting increments or estimating age.
- Otolith Radius Fish Length Back Calc Term Tool One Fraser-Lee linear body-length/otolith-radius back-calculation with an explicitly supplied intercept.
