Stock assessment research in 1998 focused on acoustic biomass estimation of mid-winter aggregation of widow rockfish. The mid-winter aggregation near Triangle Island is well known to fishers. They suggested that the aggregation might, if estimated, be large enough to alter Department perceptions of harvest limits. A joint Fisheries and Oceans and Industry survey aboard the C.G.R.S. W.E. Ricker and Fishing Vessel Frosti was conducted in January-February 1998. The aggregation was surveyed 20 times with a maximum estimate of 2,000 t of widow rockfish. This biomass observation was not sufficient to alter current yield recommendations.
