Summary of the outputs of the final GAM for the biomass index (kg/km²).

Explanatory variables included the single effect of factor Time of the Day (ToD) and Fishery, Year-Fishery interaction (Yr:Fishery) for each level of the factor (“Y” fishery allowed, “L” limited fishery, “N” fishery ban), longitude (Y), depth (D), percentage of dissolved oxygen (Oxy) and salinity (Sal); “SE”, standard error; “edf”, estimated degrees of freedom; “df”, degrees of freedom.本数据集的解释变量包含：日间时段（Time of the Day，ToD）因子、捕捞活动（Fishery）的单独效应，以及针对该因子各水平（允许捕捞的Y级、限制捕捞的L级、禁捕的N级）的年份-捕捞活动交互效应（Year-Fishery interaction，Yr:Fishery）；此外还包括经度（记为Y）、水深（D）、溶解氧百分比（Oxy）与盐度（Sal）；其中“SE”代表标准误（standard error），“edf”代表估计自由度（estimated degrees of freedom），“df”代表自由度（degrees of freedom）。
