Reconciliation of processed catch statistics with log data for 1992-97 flatfish in 4vwx/5y / G.M. Fowler and W.T. Stobo. : Fs70-1/1999-149E-PDF

During recent years (1992-97) 30-60% of Scotia-Fundy area landings are represented in the Commercial Landings database as unspecified flounder. This creates difficulties when attempting to assess stock status of individual species (American plaice, winter flounder, witch flounder, yellowtail flounder) where the unspecified portion of the landings acts as an ambiguous catch-all for much of the catch. Given the desirability of obtaining Commercial Landings data associated with correct species assignments. The relationships between the Commercial Landings data and computerized logbook (Fishing Log) data for recent years (1992-97) were investigated. The main goal was to reconstruct commercial landings of the major commercial flatfish stocks of American plaice, winter flounder, yellowtail flounder, and witch flounder where the processed Commercial Landings data record unspecified flounder. A secondary objective was an examination of differences in species identity between the Commercial Landings data and the Fishing Log data in instances where species were named.
