Results of the regular GAMs (a) and QGAMs (b) for the total egg data, and the regular GAMs (c) and QGAMs (d) for seasonal data of the spring (April) assuming a Gaussian and ELF error distribution; temperature (Temp10, °C), salinity (Sal10,psu), and dissolved oxygen (DO10, ml/L) at the 10 m depth layer, the salinity difference between 10 m and 50 m depth layer (Sal1050, psu), and zooplankton biomass (Zoop, Log10 mg/m3). The solid lines represent the main effects of the independent variables. The dotted lines represent the 95% confidence intervals in the GAMs (a and c). Each legend (b and d) represents the quantiles (0.1th, 0.5th, 0.7th, 0.9th) of the egg density
