根据西班牙水面延绳钓船队在23年（1989-2011年）期间捕捞南大西洋箭鱼种群的行程，使用一般线性建模程序更新了数量和生物量的标准化渔获量。同期的名义渔获量也作了更新。用来界定区域、时间段、渔具、鱼饵、捕鱼战略和模式等因素的标准与以前的文件中使用的标准相似。最终模型分别解释了数量和重量的65%和71%的CPUE变异性。统计诊断非常令人满意。结果表明，随着时间的推移，标准化CPUE和平均体重趋势非常稳定。恢复
SUMMARY Standardized catch rates in number and biomass were updated using General Linear Modeling (GLM) procedures from trips carried out by the Spanish surface longline fleet fishing the South Atlantic swordfish stock during a period of 23 years (1989-2011). Nominal catch rates were also updated for the same period. The criteria used to define factors such as area, time periods, gear, bait, fishing strategy and models were similar to those used in previous papers. The final models explained 65% and 71% of the CPUE variability in number and weight, respectively. The statistical diagnoses were highly satisfactory. The results point to very stable standardized CPUE and mean weight trends over time. RESUME
