Table 1

Overview of demersal marine fish data (ordered taxonomically) used in analysis and their population trends over time. (Regions: NEA, Northeast Atlantic; NWA, Northwest Atlantic; NMA, North mid-Atlantic; NEP, Northeast Pacific. Abundance metrics: SSB (model-based estimates of spawning stock biomass), BTOT (model-based estimates of total population biomass), NSSB (model-based estimates of the abundance of spawning individuals), CPUETOT (catch-per-unit-effort of all individuals in a fisheries-independent survey), CPUESSB (catch-per-unit-effort of the breeding population in a fisheries-independent survey). Change in abundance: D, decreased; I, increased; S, stable; ?, status unknown. Life-history data review: Amat (age at maturity), Lmat (length at maturity), growth (length-at-age or weight-at-age from fishery or population assessment data), age-structure (numbers-at-age from research survey or population assessment data): (1, time-series of data available; 0, otherwise).)

  • d Research survey gear changed in this area in 1995, such that for stocks where comparisons of catchability between the gear were not done, time-series prior to and after the change are not comparable. As such, post-1992 slopes for these populations are the slope from 1995 onwards, and total change in abundance is undetermined.
