The upper plate indicates southern albacore spawning biomass over time, projections with aconstant catch of 25,000 t over the next years and the reference B MSY level with 80% confidence bounds. Thelower plate indicates catch relative to replacement yield vs. current biomass relative to the biomass at MSY forthe period 1970-2005. The circles are the current state of the stock for all the sensitivity runs.69
