Estimated spawning output expressed as a share of the egg production of the unfished stock. It is the fishery’s primary biological sustainability limit — the line management is most determined not to cross.
The fishery’s limit reference point requires egg production to stay above 30% of the unfished level, and management aims to meet it with 90% probability.
IMAS Tas Fisheries ↗Egg production is the guarantee that the stock can replace what is caught. Holding it above the 30% limit with high confidence is what keeps the fishery certified and open; watching it flags when catch limits must tighten before recruitment is put at risk.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Release all berried (egg-bearing) females unharmed.
Respect size limits that let females spawn before capture.
Back area and seasonal closures that protect spawning stock.
