Fishery tools

Box Label Maker

Create seafood box labels from product name, lot, catch date, weight, and storage temperature. Export A4 sheet PDF or PNG, switch between QR and Code128, import CSV in bulk, and adjust field names, order, units, and date formats for buyer rules.

Fish Box Loading Calculator

Estimate the maximum box count, layers, and leftover space from cargo-space dimensions and fish box or cooler dimensions. Includes floor rotation, stack limits, margin %, 2D layout preview, CSV/print memo, and shareable URLs.

Fish Yield Calculator

Calculate edible seafood weight, loss weight, effective cost per edible kg, and estimated servings from raw weight, yield percentage, or a loss breakdown. Save company standards, combine multiple lots, export CSV, and print.

Boat Fuel Cost Calculator

Estimate fuel use and fuel cost for a fishing trip from distance, average speed, fuel burn (L/h or L/nm), and fuel price. Add multiple legs, idle time, and a safety factor for wind, waves, and detours.

Brine Concentration Calculator

Calculate the salt needed from a target brine percentage. Switch between %w/w (weight %) and %w/v (weight/volume %). Includes initial salinity, g/oz display, and optional additives such as sugar.

Rope Length Calculator

Estimate rope length for mooring, anchoring, or buoy lines from depth, tide range, wave and wind factor, scope ratio, and extra allowance. Show minimum, recommended, and purchase-ready length in m or ft.

Fish Ice Calculator

Estimate required ice from fish weight, temperature, and transport time. Includes insulation and ice-type adjustments, shareable URLs, and CSV export.

Seafood Thawing Time

Estimate a seafood thawing time range from weight, thickness/shape, and method. Room-temperature thawing is not recommended. Includes short notes on drip and bacterial-growth risk.

Fish Length to Weight

Estimate fish weight from body length in cm or inches. Use preset or custom coefficients a and b, save coefficient sets in the browser, share them as JSON, derive a from one sample, fit a and b from multiple samples, and batch-calculate many fish at once.

Traceability QR Generator

Create traceability QR codes offline from lot data, review the text content, and verify scannability on one screen. No personal data required and nothing is uploaded.
