Cultch

Overview

Cultch is a complete husbandry, harvest, purification, classification and trade platform for a native oyster and mussel fishery working a tidal estuary. It manages shellfish beds, hatchery operations, depuration and official classification, then handles grading, packing and buyer traceability through a portal styled as an Admiralty hydrographic chart.

What you get

• Bed ledger holding 610 hectares across nine named grounds, with character, gear, stocking density, standing stock, mortality and closure state
• Hatchery workflow from broodstock conditioning through spawning events, larval rearing and spat settlement on cultch
• Four intertidal trestle sections and a relaying ground, scheduled against tide table, salinity and water-column readings
• Six ultraviolet depuration tanks with cycle times, flow rates and signatory sign-off
• Statutory classification and biotoxin regime: official monitoring points, E. coli results, biotoxin assays and phytoplankton counts with grounds opening and closing on the record
• Grading and packing by run and format under live-shellfish handling rules
• Merchant and restaurant accounts tracked against the R-months convention
• Buyer portal that traces a box back to its ground and tide

The signature screen

The bed ledger is the central record, holding all nine named grounds with their character, gear, stocking density, standing stock, mortality and closure state across the 610 hectares of regulated shellfish beds. It anchors the husbandry and harvest workflow, connecting every tidal operation and depuration cycle to its source ground and regulatory status.
