摘要: It is easier to monitor the spawning area of Pacific sardine than mount a full-scale effort precisely estimate biomass. Monitoring may be particularly economical when extremely rare or abundant. Such imprecise estimates will probably not answer management question whether set specific biomass quota. Thc candidate- with acrial surveys, scale sedimentation rates, and acoustic-trawl surveys- for use in interpolating betwren ycars whcn iiiorc prrcisc SWFC daily egg production method used.
